Dog breeds commonly affected include the German Shepherd dog, Weimaraner, Golden Retriever, German Shorthaired Pointer, Saint Bernard, Newfoundland, Dogue de Bordeaux, and English Bull Terrier. The anatomic appearance of the subvalvular lesion ranges from a number of small fibrous plaques on the endocardial surface of the left ventricular outflow tract on the interventricular septal aspect, to a completely encircling fibrous band just below the aortic valve (Maxie, M.G. Pathology of Domestic Animals, 2015). | 04/29/2022 | ||||||

Arising from the conjunctiva of the right lower eyelid is a well-demarcated, oval, firm, pale tan, 2-cm diameter mass. The left ethmoturbinate and left parasinuses, including the frontal sinus, middle conchal sinus, ventral conchal sinus, and sphenopalatine sinus, are effaced by multiple firm to hard, tan, multilobulated coalescing masses. The largest mass is 9-cm x 7.5-cm x 6-cm. The mass markedly compresses and displaces the nasal conchae and invades the overlying frontal bone and the adjacent orbital bone. Multiple masses contain a necrotic center. The left parasinuses are filled with thick, tan to yellow purulent material. Histologically, the conjunctival and paranasal sinuses mass confirm a squamous cell carcinoma. (Pathologist: Dr. Katharine Horzmann). | 04/06/2022 | |||||

The mite burrows itself in the stratum corneum of the animal and results in a hypersensitivity reaction leading to severe pruritis. The lesions are first noted in the anterior aspect of the animal’s body (ears, head and neck) and then progress to other areas. Lesions associated with the mite start as macules, papules, and crusts to then progress to scaling, lichenification and alopecia. | 04/04/2022 | |||||

Botryomycosis is usually caused by Staphylococcus aureus and results in a Staphylococcal cellulitis. This is a chronic pyogranulomatous disease that affects the skin typically and in some instances internal organs. Although the lesions resemble fungal granulomas, this is not a fungal disease. The initiation of the lesion typically requires a traumatic (e.g. bite wound, foreign body, etc.) event; however, some theories exist on what predisposes the animal in developing such lesions. | 04/04/2022 | |||||
