Resumo: The clinical, gross and microscopical features of a granulosa cell tumour in the ovary of a 2-year-old cat are described. This is a rare tumour in cats, moreover because of the animal’s age. It was diagnosed clinically by ultrasound examination. The tumour, a cystic mass in the region of the left ovary, metastasized to the epiplon and lungs. Tumour cells expressed vimentin and were arranged in a diffuse sarcomatous pattern, supported by a fine fibrovascular stroma. The presence of hair loss and repeated oestrus as clinical signs are indicative of orthoendocrine paraneoplastic syndrome, due to excessive oestrogen stimulation. This tumour should be considered in the differential diagnosis of behavioural disturbances in female cats.

Essa neoplasia é rara em gatos, principalmente devido à idade apresentada pelo animal. O diagnóstico foi feito clinicamente através de exame ultra-sonográfico. O tumor, uma massa cística na região do ovário esquerdo, metastatizou para o epíploo e para os pulmões. As células tumorais expressaram vimentina e arranjavam-se num padrão sarcomatoso e difuso, sustentado por fino estroma fibrovascular. A presença de sinais clínicos, como perda de pêlos e repetição de estros, é indicativa de síndrome paraneoplásica ortoendócrina, devido à excessiva estimulação estrogênica. A existência desse tipo de tumor deve ser considerada no diagnóstico diferencial de distúrbios comportamentais em gatas.Universidade de São Paulo.
