Plain-English summary
A 3-month-old Arabian filly was found to have a juvenile granulosa cell tumor, which is a type of tumor that affects the ovaries. This tumor was quite large, measuring about 32 by 27 centimeters, and had taken over the right ovary. The tumor was made up of different types of abnormal cells that formed various structures, including small and large clusters, as well as some cysts. The diagnosis was made based on the filly's age and the appearance of the tumor under a microscope.
Abstract
A juvenile granulosa cell tumour is described in a 3-month-old Arabian filly. The 32 X 27 X 27 cm tumour had replaced the right ovary. The neoplasm was composed of multiple nodules of neoplastic granulosa cells which formed microfollicles, macrofillicles and cysts, as well as solid nests and trabeculae. The supporting stroma contained theca cells. Mixing of the neoplastic granulosa cells and theca cells in disorderly fashion was noted. The diagnosis was based on age of occurrence and histological appearance.
