Common Diseases of the Canine Nasal Planum with emphasis on Discoid Lupus Erythematosus Dr Robert Hilton BVSc(Hons) MANZCVS (Canine Medicine) Cert.VD MRCVS Mobile 0433-85356 . Although the exact etiology is unknown, an association with atopy has been suggested.8 Nasal planum lesions are common, along with depigmentation of mucocutaneous junctions, pronounced erythema, and scaling (Figure 12 Dermal arthritis of the nasal philtrum This is a rare disease seen in large breed dogs such as Saint Bernards, Giant Schnauzers, and Great Danes. It is unique in that it only affects the large arteries and arterioles of the nasal philtrum causing focal erosions to ulcers in that region only Mucocutaneous pyoderma (MCP) is a common condition that may affect the nasal planum. MCP is a bacterial infection usually caused by Staphylococcus pseudintermedius. German shepherd dogs are the most commonly affected breed Nasal planum SCC is common in cats and rare in dogs. Tumors: LSA, FSA, hemangioma, melanoma, MCT, and fibroma. Non-neoplastic conditions of the nasal planum include eosinophilic granuloma and immune-mediated disease. SCC associated with ultraviolet irradiation (UVA and UVB) from sunlight
Although dogs with both food allergy and atopic dermatitis have facial pruritus, it is unusual to see lesions confined to the nasal planum in either disease. White-haired animals are more prone to sunlight-induced disease. The earliest lesions appear as actinic dermatitis where there is mild erythema and scaling 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 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

This particular brand contains 7 different oils and butters (such as Shea butter, coconut oil, and olive oil) designed to absorb in layers on your dog's nose Squamous cell carcinoma of the nasal planum was diagnosed in 17 dogs over a period of 11 years. Ulceration, bleeding and sneezing were the most common clinical signs. One dog had cytological evidence of metastasis to the local lymph node. The dogs were treated by surgical resection, fractionated meg The nasal plane is the first and hairless part of the nose of dogs and cats, and is covered with thick keratinized epidermis Squamous Cell Carcinoma of Nasal Planum in Dogs The epithelium is the cellular covering of all of the internal and external surfaces of the body, protecting the organs, inner cavities and outer surfaces of the body in a continuous layer of multi-layered tissue
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 The purpose of this article is to review the therapeutic options available for the treatment of squamous cell carcinoma of the nasal planum in cats and dogs. The techniques of complete and partial nasal planum resection in the cat are described in detail. Surgical treatment offers the greatest chanc This disease is rare in very young and brachycephalic dogs, but is often seen in Golden Retriever and Rottweiler dogs in the Netherlands, male and female dogs are equally affected. Erosion of the nasal planum with depigmentation and an abundant unilateral or bilateral sanguinopurulent, mucopurulent or hemorrhagic nasal discharge are usually noted 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
Nasal Dermatoses in Dogs. Nasal dermatoses are diseases of the skin on or near the nose. The nose itself is often referred to as the nasal planum. Some of these conditions are sometimes known as Collie nose or nasal solar dermatitis, depending on the cause. Many diseases may cause these conditions in dogs. These may affect the bridge of the. How common are nasal planum tumors in cats and dogs? Cancer of the nasal planum is rare in dogs but relatively common in the cat. It is usually observed in older, lightly pigmented cats. What are the symptoms of nasal planum tumors in cats and dogs? Invasive SCC typically evolves over time (months to years) and progresses through several stages Punch biopsies are most often performed, and typically a 6-mm punch is used. Reserve 4-mm punches for pinnae, the nasal planum, or footpads of small dogs and cats. Obtain punches from the center of a lesion unless it is an ulcer, and center small lesions within the punch
nasal planum tumors. BACKGROUND. 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 Nasal arteritis in dogs is a moderate to severe inflammation of the nasal area. The artery walls are affected, causing bleeding, which can often be severe. It is also characterized by a raw and reddened inflammation on the nasal planum. Symptoms of Nasal Arteritis in Dogs The right half of the nasal planum was dry and the right nostril was occluded with dried debris (Figure 2). What are your differential diagnoses and what are your next diagnostic steps? This dog has unilateral severe keratoconjunctivitis sicca (KCS) accompanied by ipsilateral xeromycteria (dry nose) A Lesson in Anatomy. A dog's nose is composed by different parts. The visible part that one can see, basically the leather-like part that is hairless right at the end of the nose, is called the nasal planum.The very tip of the dog's nose -the rhinarium - is the part that is typically moist and cool to touch. Dogs have two nostrils (nares) which are divided by the septum in the middle 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
depigmentation of the nasal planum beneath the discharging nostril(s). Dogs with nasal tumours can occasionally have major discharge (through secondary bacterial infection or epistaxis), but this tends to be less profuse and rarely exhibits overt facial pain, and usually any discharge would be unilateral (at least initially) The most common cause of problems with the nasal planum (the normally black area of the nose) in German shepherd dogs is probably discoid lupus. Phemphigus is another possible problem. There are reports of nasal inflammation and necrosis (death of tissue) associated with Rocky Mountain Spotted Fever infections and this would also be a cause of.
The various causes of loss of pigmentation of the nasal planum (the usually black portion of the nose) that I can find good references for are: 1) Dudley nose -- loss of pigment seen in a number of breeds for unknown reasons in which the nose is black when dogs are young but fades to brown or sometimes even white as the dog ages 1. A pustule just caudal to the planum nasale of a dog; alopecia and erythema are also present in the dorsal nasal region. CLINICAL SIGNS. The earliest lesions of pemphigus foliaceus consist of erythematous macules that then progress rapidly to a pustular stage. Pustules tend to be large, irregular, and coalescing (Figure 1) Dogs with DLE typically develop erosions, ulcers, and depigmented areas (light discoloration of the skin) around the nose. In many patients, the nasal planum (the hairless area surrounding the nostrils) will become smooth, losing its bumpy, cobblestone-like texture
nasal planum vasculopathy of the Scottish Terrier dog, dermal arteritis of the nasal philtrum, discoid lupus erythematosus, pemphigus complex, squamous cell carcinoma, and leishmaniosis. The latter was unlikely because the dog lived in a nonendemic area in Northern Italy and Immunoﬂuorescence Antibody Test titer was negative Nasal tumors, regardless of histologic type, are characterized by locally invasive growth. Metastatic rate is low at diagnosis but reported in up to 50% of dogs at necropsy. Metastatic sites include lymph nodes and lungs ± bone reported in 2 dogs. Benign nasal tumors include adenoma, basal cell tumor, fibroma, and neurofibroma The nasal planum and the central part of the upper lip were absent, and two remnants of the nares were present; however, the dog could breathe and eat normally. More than one and a half years after the start of the medications, the dog is still on treatment with 5 mg/kg ciclosporin orally once daily, breathes and eats normally, and the quality.
When a dog is experiencing DLE, the following signs may be noted: Loss of color around the nasal planum (the thick, cobblestone skin around a dog's nostrils) Erosions, ulcers, bleeding, and thickening of the nasal planum; Sometimes also occurs on the ears, around the eyes, and on the feet, though that's much rare Being the last of a litter, his deformity was known as congenital defect in nasal planum aplasia. The shelter replied, We were told the little guy was six weeks old and a third of the size of his litter-mates. Rudolph's upside down nose meant that both his nostrils and snout were inverted.

There are other breeds of dogs that are prone to a seasonal lightening of the nasal planum (the hard, tough, hairless end of their nose). Sometimes referred to as Snow Nose these dogs ( Siberian Huskies , Labradors and Golden Retrievers) can have darker noses in the summer months and lighter noses in the winter A general observation, most dogs have a black nose! However, there are also variations that result in a lighter almost pink or brown pigmentation of the nose. And, in some cases, that rich black. Hereditary nasal parakeratosis (HNPK) is an inherited disorder described in Labrador Retrievers and Greyhounds. It has been associated with breed-specific variants in the SUV39H2 gene encoding a histone 3 methyltransferase involved in epigenetic silencing. Formalin-fixed biopsies of the nasal planum of Labrador Retrievers were screened by immunofluorescence microscopy for the presence and. Lupus is an immune-mediated disease stemming from one?s own immune system reacting against one?s own DNA. Discoid lupus is a form of lupus that is confined to the skin and is substantially more benign because of this confinement. Discoid lupus, or DLE is almost exclusively a canine disease and is almost always limited to the leather of the nose, called the nasal planum
The nasal planum will look normal with the only difference being that the color is slightly lighter than what it is supposed to be. Basically, it happens when a young dog can start off with a black nose, but as they get slightly older, the nose changes to brown and sometimes pink or white Introduction. Dermal arteritis of the nasal philtrum is a rarely described disease process which has been documented in a Giant Schnauzer, 1 Saint Bernard, 1 Newfoundland, 2 and a Basset hound. 3 The typical lesion is a solitary, well-circumscribed circular ulcer which is non-pruritic and most commonly non-painful on the nasal philtrum ().The nasal planum is unaffected in these patients. 1.

The respiratory system has many parts, but the two important parts of the upper respiratory system are the nose and paranasal sinuses. The paranasal sinuses are hollow spaces in the bones of the skull. They connect with the nose and help to add moisture to the air that a dog breathes in through its nose The nasal planum is the pigmented, hairless, rostralmost surface of the external nose.

A nasal tumor is a type of cancer that results from the disorganized uncontrolled production of cells that line the nasal airway. In dogs, the most common nasal tumor is nasal adenocarcinoma. Nasal adenocarcinomas originate from the glandular cells (e.g., sebaceous glands) in the nasal cavity. In cats, the most common nasal tumor is nasal lymphoma . 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. *Depigmentation of the nasal planum is usually due to one of the autoimmune diseases (discoid or systemic lupus erythematosus, pemphigus, or bullous pemphigoid) or much less commonly nasal solar dermatitis (Collie nose). However, the author has seen several dogs with this presentation, which i The clinical presentation is dependent on the type of breed, inciting factors (natural or drug induced) and the cyclical nature of the disease. Clinical lesions include pustules, crusts, erosions, ulcers and alopecia. The most common areas involved are dorsal muzzle, nasal planum, pinnae, periorbital skin and paw pads cough, but most infected dogs progress to pneumonia and a wasting syndrome. Other clinical signs include vomiting and diarrhea similar to parvovirus, dry eye, photophobia, pustular skin rashes, or development of seizures and myoclonus within 1-3 months. Some dogs develop hyperkeratosis of the nasal planum and footpads (hardpad)
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) Nasal hyperkeratosis impacts your dog's nose and muzzle area, while foot pad hyperkeratosis impacts your dog's feet.. Both types of hyperkeratosis can be incredibly uncomfortable and even painful for your dog.

And subsequently reported in a handful of further dogs. St Bernards and GSDs appear particularly over-represented amongst affected dogs. Our case, Selous, we first saw about 18 months ago Additionally, it can be difficult to obtain a large enough biopsy sample from the nasal planum of small dogs. Here's a link to an article that describes the basics about this autoimmune disorder. My favorite treatment for it is tacrolimus ointment. It's expensive, but works better than anything else
appearance of the nasal planum and eventual development of erosions, ulcers and crusts. Scarring may occur in severe and chronic cases.

nasal planum. Unlike lesions in patients with mucocutaneous pyoderma and discoid lupus erythematosus, inflammation and crusting are not associated with depigmentation. d FIGURE 6 Discrete, strikingly depigmented patches of vitiligo and leukotrichia affecting the lip margins, muzzle, and nasal planum of an adult crossbreed German shepherd dog The secondary infection of the nasal planum is probably a result of one of these disorders. There are of course other possible reasons for the problem including Rocky Mountain Spotted Fever (there would also be thromobocytopenia on a blood test), or a slight possiblity of cancer (which can only be diagnosed by a biopsy). Since your dog is older.

Chiti , Marta L P Lisi , Dario Drudi , V. Montinaro , Paolo Sommarug N2 - 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 Several breeds are known to be predisposed to this type of cancer. This tumor may affect any area of the skin, the nose/nasal planum, or the toes. Fine needle aspiration or biopsy may be performed for diagnosis. About 30% of dogs with the digital form of the disease will have evidence of spread
The gums and lips are the most common sites for the first signs of vitiligo. 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 Discoid (cutaneous) lupus erythematosus is a relatively benign variant of systemic lupus erythematosus that primarily affects facial skin. The most common site is the hairless surface of the bridge of the nose, called the nasal planum or planum nasale. Other sites are the lips, mouth, periocular area (around the eyes), pinnae (ear flaps) and. It could lead to vitiligo in dogs and exhibits symptoms such as: Skin depigmentation on the footpads, hard palate, anus, scrotum, eyelids, lips and nose. The eyes become sensitive to bright light.
