Squamous cell carcinoma (SCC) is the most common tumor of the nasal planum in cats, but this tumor is rare in dogs. SCC of the nasal planum and ear pinnae is caused by ultraviolet radiation and white-haired cats have a 13.4-times greater risk of nasal planum SCC. They are locally invasive tumors Squamous cell carcinoma Squamous cell carcinoma most commonly affects pinna, eyelids and nasal planum in cats that lack pigment in these areas. Nasal planum SCC reflects 13 per 10,000 hospital admissions. Cutaneous SCC generally is 9-25% of feline cutaneous neoplasia Skin: neoplasia
Nasal Dermatoses in Cats. Many diseases affect the skin on the noses of cats. This can include bacterial or fungal infections of the skin, or mites. These diseases may affect the bridge of the nose where there is hair, or the smooth part of the nose, where there is no hair. Often, it is the portion of the nose that has hair that is affected Lymphoma, or cancer of the lymphocytes, is the most common cause of nasal cancer in cats. The most common cause of feline nasal cancer is lymphoma. Lymphoma is a cancer of the lymphocytes, which are white blood cells that function as part of the immune system. It can affect many different regions of the body, one of which is the nasal passages Other causes of nasal planum dermatitis are: Eosinophilic furunculosis of the face, feline herpes virus dermatitis, mosquito bite hypersensitivity, solar nasal dermatitis, drug eruptions, erythema multiforme, toxic epidermal necrolysis, bullous pemphigoid, Distemper, leishmaniasis, necrolytic migratory erythema (hepatocutaneous syndrome), hereditary pyogranuloma with vasculitis of Scottish terriers, tyrosinemia, parasympathetic nose, histiocytomas, and dermatomyositi
Neoplasia of the nasal planum is more common in cats than dogs, and squamous cell carcinoma is thought to be the most common form of neoplasia arising on the nasal planum. 36, 192 Other tumors reported in this location include lymphoma, 123 malignant histiocytosis, 122 fibrosarcoma, 93, 101 malignant melanoma, 193 lymphomatoid granulomatosi, 193 basal cell carcinoma, 193 fibroma, 36 mast cell tumor, 53 hemangiomas, hemangiosarcoma, 115 and eosinophilic granulomas. 3 Sneezing and nasal discharge in the cat can result from infectious, inflammatory, or neoplastic disease. The most common syndrome is likely chronic rhinosinusitis (CRS), a disease with high morbidity in the feline population but uncertain etiopathogenesis SCC of the nasal planum is common in the cat but rare in the dog, probably because dog plana are more reliably pigmented. SCC most commonlyaffects the nasal planum, pinnae and eyelidmargins of cats, while the dog is most frequently affected in the caudal abdomen, flank and nail bed. It is a disease of older animals. White-haired cats have 13.4 times the risk of developing SCC than other-coloured cats There are many types of skin diseases that may develop on the nose of a cat. We would consider a fungal or bacterial infection, cat acne, a bite wound, cancer or other condition that causes nasal lesions. Symptoms of Nose Skin Disease in Cats The symptoms may vary according to the origin of the skin disease, but usually consist of
PF is the most common condition of the pemphigus complex 3,8 and is the most frequently occurring autoimmune skin condition in dogs, cats, and horses. The disease usually appears to be idiopathic, although it has been associated with drug administration and can develop subsequent to chronic, usually allergic, skin disease. . The most common clinical sign for owners to seek veterinary care in reference to the nasal planum is depigmentation in dogs and ulceration in cats. Proliferative (nodular) diseases are less common in dogs than in cats, because cats are more prone to develop squamous cell carcinoma of the nasal planum
Proliferative (nodular) diseases are less common in dogs than in cats, because cats are more prone to develop squamous cell carcinoma of the nasal planum. Because a wide variety of diseases may present with similar clinical signs, the most helpful diagnostic test (after a thorough history and physical examination) is a skin biopsy. Discoid. Diseases of the nasal plane in cats are uncommon with the exception of tumours. The most common tumor of the nasal plane in cats is squamous cell carcinoma (SCC). This tumor manifests itself as a progressive ulcerative and erosive inflammation of the nasal plane
Squamous cell carcinoma (SCC) is one of the most common skin tumors of the cat and tends to occur in sites which are nonpigmented and have relatively little hair covering, such as the nasal planum, eyelids, and pinnae. 1 SCCs are classified according to the World Health Organization staging system for feline tumors of epidermal origin. 2 Cutaneous tumors, classified as T is, T 1, or T 2 can be. The most common sites of lesion development on a cat, she says, are the temples, the outer tips of the ears (pinnae), the eyelids, the lips and the nasal planum, which Dr. McEntee refers to as the little button at the end of a cat's nose. About one-third of cats diagnosed with SCC of the skin, she notes, have multiple lesions Cases with lesions but without concomitant signs of nasal disease probably result from cat scratch injuries. Under certain circumstances, such lacerations result in the introduction of saprophytic microorganisms in such large numbers that host defence mechanisms are overwhelmed Nasal planum neoplasia. The nasal planum consists of stratified nonhaired epithelium of the nose. Cancer of this area is less common in dogs and more common in cats-ultraviolet (UV)-induced squamous cell carcinoma (SCC) being the most common, says Fan. UV-induced SCC starts out as a nonhealing wound Cats with SCC of the nasal planum that were managed with nosectomy have good to excellent prognosis.1 Median survival time and disease-free interval for cats having nosectomy is 673 days and 594 days respectively.1 Ideally, avoidance of sunlight is advised for all patients even after surgical treatment to prevent recurrence or new lesions in.
SCCs are the most common tumors in cats and account for approximately 10.4% of feline skin tumors above all involving the nasal planum, with ear pinnae and eyelids also affected [1-3]. Cats older than 10-12 years are usually at higher risk [2,4]. In cats, cutaneous SCCs are mainly associated with chronic solar exposure (UV light)ā Nine cats and five dogs were subjected to completed surgical removal of the nasal planum for various neoplasms. Local recurrence occurred in three cats with advanced squamous cell carcinoma. Functional results were good in all patients, while the cosmetic result was good in cats and fair in dogs
OBJECTIVE: To evaluate curettage and diathermy as a treatment for actinic dysplasia and superficial squamous cell carcinoma of the feline nasal planum. METHODS: Thirty-four cats clinically assessed to have actinic dysplasia and superficial squamous cell carcinoma involving less than 50% of the nasal planum were treated with a three-cycle. For Peer Review 1 Response, disease-free interval and overall survival of cats with nasal planum 2 squamous cell carcinoma treated with a fractionated versus a single-dose 3 protocol of strontium plesiotherapy 4 5 Authors: 6 Berlato, D., Oncology Unit, Animal Health Trust, Newmarket, United Kingdom 7 Murphy, S., Oncology Unit, Animal Health Trust, Newmarket, United Kingdo Cutaneous squamous cell carcinoma of the nasal planum in cats is a common indication for antitumor treatment such as external beam radiation therapy. Curative-intent radiation therapy has been described as a valuable treatment option, resulting in long and stable tumor control in these patients. The aim of the current study was to evaluate outcome and toxicity, as well as possible prognostic. 1,146 days, 23 (45%) cats were alive and disease free, 17 (33%) had to be euthanized due to tumor recurrence, and 11 (22%) treatment of superļ¬cial nasal planum SCCs of cats and offers an alternative to conventional therapy. Although initial response rates were high, this treatment did not lead to a durable remission or cure in all cases.. Crusts then form followed by fissuring and erosion in some cases. A purulent discharge is often present and the crusting can extend to the dorsal aspect of the nasal planum (NP). DLE is the most common ddx and it can be difficult to distinguish between these two diseases clinically and histologically

From 528 quotes ranging from $200 - $1,800 IDIOPATHIC nasodigital hyperkeratosis is a condition that manifests as excessive accumulation of keratin on the dorsum of the nasal planum and/ or footpads. Brachycephalic breeds and cocker spaniels may be predisposed. The characteristic sign is thickened, dry and hard keratin accumulating in the sites mentioned
Phaeohyphomycosis has been described in cows, cats, horses, and dogs. The most common clinical presentations include ulcerated cutaneous nodules of the digits, pinnae, nasal planum, and nasal/paranasal tissues in cats. The nodules may ulcerate and have draining fistulous tracts. These pyogranulomas contain pigmented, septate hyphae with. Nasal Arteritis. Cause: Nasal arteritis is an ulcerative disease of the center of the nasal planum in dogs, caused by immune mediated inflammation of the walls of the nasal arteries/blood vessels. Affected animals: This condition is most commonly seen in certain breeds such as St. Bernards and Standard Schnauzers, but can occur in other breeds as well.. Pemphigus is a cutaneous auto-immune skin disease which most commonly occurs in middle aged to older cats and is characterized by pustular and crusted lesions commonly observed on the ears, nasal planum, periocular area, chin, and paws.. The most common form of this disease in cats is pemphigus foliaceus, but a number of variants have been reported, including pemphigus vulgaris (which involves.

Diseases of the nasal planum and footpads in cats and dogs range from benign disorders to severe, life-threatening conditions. Changes in the architecture of the skin in these regions can, in the early stages, be very subtle. Close observation and knowledge of specific differential diagnoses of diseases of these specialized areas of skin can be very useful as the treatment and prognosis vary. Cats with squamous cell carcinoma of the nasal planum treated with an accelerated radiation protocol (10 Ć 4.8 Gy, over one week) were retrospectively evaluated. Tumor- and treatment-associated variables were evaluated in respect to local control and survival An injured nose -- mostly likely from a cat fight or accident -- may bleed or swell, causing your cat to paw at his nose. If it worsens, this can lead to a secondary infection. Nose growths are more common in white cats, who are prone to certain skin cancers. Other growths may results can result from primary or secondary infections Feline respiratory disease complex (FRDC) is an umbrella term for respiratory illnesses in cats caused by a group of organisms and/or viruses, and is estimated to occur in approximately 25.8% of cats in high-risk group settings. These illnesses can be complicated by secondary infections, and so it is important to recognize symptoms of FRDC The front portion of the nose is flattened and devoid of hair, and is called the planum nasale, which includes the nares or nostrils. The nostrils are the entrance openings of the nasal cavity and are supported by cartilage. The nasal cavity is the air passageway within the facial area of the skull
Neoplasia of the nasal planum and palatal defects Nasopharyngeal polyps are also common in cats Why is it important to differentiate between primary tumors of the nasal cavity and oral tumors that extend into the nose Objectives: The main aim of the study was to establish response, disease-free interval (DFI) and overall survival of cats with nasal planum squamous cell carcinoma (SCC) treated with Sr90 plesiotherapy. A secondary aim was to determine whether a fractionated protocol is more effective than a single-dose protocol in terms of response, DFI and overall survival Cryptococcosis is the most common fungal disease in cats and should be an important differential diagnosis when a cat presents with sneezing and nasal discharge that is unresponsive to antibiotics. The age range of infected cats varies widely (1-13 yrs), with a mean age of 5 years. There is a predilection for infection in male cats, most likely.
The pinnae, nose/nasal planum, and footpads are most frequently affected. Lesions may include erythema, papules, plaques, crusting, punctate ulcerations, serosanguineous discharge, and erosions. Cats with outdoor access are most frequently affected. Indoor confinement to minimize mosquito exposure is best for successful management sparsely-haired areas of the skin (particularly the eyelids, nasal planum, and ears), as well as other locations within the body, such as the tonsils, under or on the tongue, mouth, esophagus, or lungs. Most cats with SCC are middle-aged to older, though this disease can affect cats of any age. White cats or cats
accurately dosing nasal tumours with radiation therapy. Radiography has been largely superseded in some practices and most referral hospitals by advanced imaging modalities, such as CT (Figure 2) and MRI. However, radiography remains the mainstay of initial nasal disease workup for most practitioners and is a great diagnostic tool Noli C, Koeman J P & Willemse T (1995) A retrospective evaluation of adverse reactions to trimethoprim-sulphonamide combinations in dogs and cats.

Vet Clin North Am Small Anim Pract 24 (5), 887-895 PubMed Medical records from a laboratory database and six contributing institutions were searched to identify cats with histologically confirmed sarcoids. Forty-two cats were included in the study. The majority of sarcoids occurred on the face, particularly rostral locations such as the lips and nasal planum Many cats do very well after a mandibulectomy, and the majority of guardians report a high quality of life in spite of some challenges relearning to eat, drink, and groom. Overall, however, any SCC of the mouth is considered very, very bad news. Cutaneous SCC of the nasal planum and ear tips carries a much better prognosis when treated early sparsely-haired areas of the skin (particularly the eyelids, nasal planum, and ears), as well as other locations within the body, such as the tonsils, under or on the tongue, mouth, esophagus, or lungs. Most cats with SCC are middle-aged to older, though this disease can affect cats of any age. Whit
SKIN DISORDERS OF THE NOSE (NASAL DERMATOSES) BASICS OVERVIEW Conditions characterized by abnormalities of the skin on the nose, involving either the haired portion (bridge of the nose) or non-haired portion (known as the nasal planum) SIGNALMENT/DESCRIPTION of ANIMAL Species Dogs and cats Breed Predilection Deformity of the face, epiphora, inability to retropulse the eyes, or ulceration on the muzzle itself often suggest space-occupying neoplastic disease.15 Loss of pigment on the nasal planum suggests sinonasal aspergillosis,23 whereas ulcers of the nasal planum can be either fungal or neoplastic in origin A locked padlock) or https:// means you've safely connected to the .gov website.

Cats predominantly have sino-nasal disease, either alone or together with local spread to the skin/subcutis of the nasal planum/nasal bridge, regional lymph nodes and less commonly to the CNS and optic nerves via the cribriform plate . It can then spread to the muzzle, nasal planum, inside the mouth and onto the hard palate and mucosa, eyelids, eyelashes, and the ears. But vitiligo can also occur on the feet, nails, legs, neck, and other places on the body Nasal planum refers to the tip of the nose and cancer development in this area is associated with exposure to ultraviolet. light and lack of pigment. The most common type of cancer is called squamous cell carcinoma (SCC) which can be further. classified into SCC in situ (localized), superficial SCC, or deeply infiltrative SCC Squamous cell carcinoma of the nasal planum is a disease commonly seen in older cats. This type of neoplasm is caracterized by thick, rough, scaly patches that may crust and bleed, or form skin lesions and erythema. The tumor can be slowly progressive and locally invasive with a low rate of metastasis to the remote tissues and lymph nodes
Almost all cats with mucopurulent or purulent nasal discharge have a fluoroquinolones can be used for cats with chronic disease. For cats that are difficult to treat, cephalosporin injections can be considered. However, this drug class is ineffective for and ulcerative lesions on the nasal planum are common. Submandibular. Animalsā49 cats with SCC of the nasal planum. ProceduresāInformation including FIV infection status, diagnosis of SCC vs SCC in situ (ie, evidence that the tumor did or did not penetrate the epidermal basement membrane, respectively), 90 Sr dose and number of probe applications, treatment-related response and complications, and recurrence. There are also usually skin sores around the edges of the nasal planum, on the bridge of the nose, around the eyelids or places like that. 7) I have seen cats with squamous cell carcinoma lose the pigment in the nasal planum as an early sign. I am not sure that this same problem occurs in dogs but I wouldn't want to totally rule it out
Seasonal nasal depigmentation (loss of pigment in the tough, hairless skin of the nose [known as the nasal planum] that occurs seasonally) Albinism (inherited disorders characterized by lack of pigment in the skin, hair, and/or eyes, due to abnormal production of melanin Hawkins1992). Body weight loss, lethargy and inapetence are the signs of general disease in the cat (mycotic infections, neoplasia). Aggressive lytic processes accompanying neoplasia and polyps may damage nasal conchae and bones and cause deformities of planum nasale. Obstruction to the respiratory tract causes snorting, intensity and frequency.
Several skin diseases in the dog may affect the nasal planum. Salient features of the common infectious skin diseases affecting the nasal planum of dogs is presented. Mucocutaneous pyoderma (MCP) is a common condition that may affect the nasal planum. MCP is a bacterial infection usually caused by Staphylococcus pseudintermedius Results Seventy-four cats were included in the study. Thirty-two were treated with a fractionated protocol and 42 with a single-dose treatment. Sr90 plesiotherapy was able to induce complete response in 74% of cats with nasal planum SCC
Morphologic Diagnosis: Nasal planum: Chronic, locally extensive, severe granulomatous rhinitis with superficial focal dermal ulceration and hemorrhage . Contributor Comment: Cryptococcus is an important dimorphic, basidiomycetous encapsulated fungal organism causing disease in humans and animals. 3,5 Cats seem to be the most susceptible species. Six cats (four males and two females) exhibited a unique dermatosis characterized by fissures, crusts, erosions and ulcers limited to the nasal planum. No other skin or internal lesions were noted, except for a heart murmur in one cat. The age of onset varied between 4 months and 1 year. The skin disease did not appear to be contagious
trigeminal ganglion. As affected cats often have a history of previous respiratory disease or recent stress, recrudescence of a latent herpesvirus infection is likely. The macroscopic lesions consist of crusts, ulcers, and vesicles, frequently on the face or nasal planum, which can be persistent or recurrent (Figure 1) The nasal planum is the pigmented, hairless, rostralmost surface of the external nose. The philtrum is the midsagittal external crease in the nasal planum. The nasal openings are referred to as nares or nostrils and open into the nasal vestibule (Figure 99-1) In cats, lesions tend to be more localised and present on the muzzle, nasal planum, pinnae, around the nipples, in the footpads and in the ungual folds. Malaise, pyrexia and anorexia may also be noted Nasal Dermatoses in Cats. Many diseases affect the skin on the noses of cats. This can include bacterial or fungal infections of the skin, Cat's noses are wet primarily due to fluid production from sweat glands on the nasal planum (hairless nose skin), although some of the moisture also comes from drainage of the inferior tear duct. In all four cats reported with PV, skin lesions were confined to the head/face, and ulcers (Fig. 4) were the only lesion described . All cats had oral cavity, lips and nasal planum involvement. In one , nearly the entire oral cavity was affected; it also had lymphadenopathy, halitosis and hypersalivation

Ear, Nose and Throat Diseases of the Dog and Cat is the ultimate reference for veterinarians and other professionals trying to diagnose and treat both common and less frequently diagnosed diseases and conditions of the ear, nose and throat A six-point scale was used for ECT toxicity. The median tumor size was 1.5 cm. CR was achieved in 65.6% of cases, PR in 31.1% and SD in 3.3%. The overall response rate was 96.7%, RR was 22.5%, median DFI was 136 days, and median PFS was 65.5 days. ECT toxicity was ā¤2 in 51% of cats In cats, the skin is most commonly affected at the temples, the outer tips of the ears (pinnae), the eyelids, the lips and the nasal planum (tip of the nose). An oral form also commonly afflicts cats, normally in the gums. An internal form that affects the liver or lungs is considered much less common. Behavior The disease may wax and wane, and fever and depression may occur if it is severe. Pemphigus erythematosus. It is similar to pemphigus foliaceus but lesions are usually confined to the face, especially the nose. There are pustules, crusts, erosions and depigmentation of the nasal planum and the dorsum of the muzzle
Nasal tumors make up approximately 1% of all cancers seen in dogs. It is thought that long-nosed breed dogs living in urban environments are at higher risk for the development of nasal tumors. Nasal tumors are seen less commonly in cats and are more frequently seen in older animals. What are the signs of Evidence of Trauma seen - yes, swollen nose, mild hemorrhagic nasal discharge. Objective: P = wnl R = wnl BCS = 5/9 EENT: Eyes clear, PLRs intact, pupils symmetrical, very mild hemorrhagic/mucoid discharge from OS. Ears clean. Nasal planum moderately swollen and erythematous/bruised with mild-mod serous to hemorrhagic nasal discharge and sneezing Nasal dermatoses of dogs may be caused by many diseases. Lesions may affect the haired bridge of the muzzle, the planum nasale, or both. In pyoderma, dermatophytosis, and demodicosis, the haired portions of the muzzle are affected.In systemic lupus erythematosus or pemphigus, the whole muzzle is often crusted (with occasional exudation of serum) or ulcerated
