Mammary adenocarcinoma and granulosa cell tumour in an aged Toggenberg goat.
An adenocarcinoma of the mammary gland was diagnosed in an aged goat with suspected chronic mastitis. On cross-sectioning, the tumour had a lobulated appearance and contained areas of calcification. Histologically, it was multicentric, exhibiting various growth patterns, including comedo, papillary and solid. There was no evidence of metastasis to the regional lymph nodes. A well-differentiated granulosa cell tumour of the right ovary was also present.
