Abstract
ABSTRACT Lymphoma is the most common lymphoproliferative disorder in cats. However, cutaneous lymphomas are uncommon in this species and can be classified as epitheliotropic or non-epitheliotropic. Epitheliotropic lymphomas are typically of T-cells and have tropism for epidermis and/or adnexal epithelium. Non-epitheliotropic lymphomas can be of either T-cell or B-cell and involve predominantly the dermis. The present study describes a case of multifocal cutaneous anaplastic large T-cell lymphoma. The skin nodules were multiple and variable in size, alopecic and erythematous in appearance and randomly distributed. Immunohistochemistry revealed positivity for the CD3 antigen, consistent with T-lymphocytes. This neoplasm should be remembered whenever multiple cutaneous nodules are observed in cats.
期刊介绍:
Publica artigos originais de pesquisa sobre temas de medicina veterinária, zootecnia, tecnologia e inspeção de produtos de origem animal e áreas afins relacionadas com a produção animal. Atualmente a revista mantém 628 permutas (419 internacionais e 209 nacionais), sendo um verdadeiro suporte para o recebimento de periódicos pela Biblioteca da Escola.
A partir de 1999, a Escola de Veterinária delegou à FEP MVZ Editora o encargo do gerenciamento e edição de todas suas publicações, inclusive do Arquivo, ficando somente com o apoio logístico (instalações, equipamentos, pessoal etc.). O apoio financeiro é exercido pelo CNPq/FINEP e pela própria FEP MVZ.
