CASE HISTORY AND CLINICAL FINDINGS: A 15-year-old neutered male domestic short-haired cat was presented due to multiple 0.5-2 cm-diameter crusting plaques in the left preauricular region, over the bridge of nose, and in the right periocular region. The plaques did not appear to cause discomfort....

Four Felis catus papillomavirus (FcaPV) types have been fully sequenced from domestic cats. Of these, FcaPV-2 and -3 are thought to cause feline viral plaques and Bowenoid in situ carcinomas. Two short sequences of DNA from a previously unreported PV type were amplified from a feline viral plaque...

A 2-year-old castrated male cat presented with alopecia and itching on the head for approximately two months. Macroscopically there were ulcerative lesions with reddish crusts and alopecia with dander and follicular casts on the skin of top of the head and neck. Histologically, there were diffuse...

Background: Exfoliative dermatitis has been described in cats as a paraneoplastic skin disease associated with thymoma. There are anecdotal reports of cases without thymoma, with various suspected aetiologies. Hypothesis/Objectives: To identify common features, underlying causes, response to...

Skin tumors with adnexal differentiation are commonly reported in dogs and cats, while only anecdotal evidence is available in sheep. Here we illustrate the macroscopic, histologic, and immunohistochemical features of a cutaneous lesion with adnexal differentiation in a 6-year-old female Sarda...

We propose a new scenario for mammary evolution based on comparative review of early mammary development among mammals. Mammary development proceeds through homologous phases across taxa, but evolutionary modifications in early development produce different final morphologies. In monotremes, the...

The clinical presentation, diagnosis, prognosis, and treatment of abscesses, panniculitis, neoplastic nodular lesions, non-neoplastic nodular lesions, nodular sebaceous hyperplasia, and neoplastic mast cell in dogs and cats are dicussed.

In this analysis of sebaceous gland tumours of 9 cats submitted over 3 years, 8 of the cats were domestic shorthairs, 6 were male, and the cats ranged from 5 to 17 years of age. The sebaceous gland tumours accounted for 9 of 281 feline skin tumours received during this period. Of the lesions, 6...

A survey was undertaken aiming to obtain an overview of ocular and periocular lesions diagnosed in domestic mammals over a period of 50 years in a veterinary pathology diagnostic laboratory in the Central Region of the State of Rio Grande do Sul, Brazil. In this lab, 33,075 histophatological exams...
