Abstract

Granular cell tumor was described in the testis of two rabbits. Testis from each rabbit was surgically removed and submitted for histopathological diagnosis. Both testes were about 2.0 cm in diameter, firm, and tan. Microscopically, testicular mass consisted of compact sheets of round to polygonal and occasional spindle-shaped cells. The neoplastic cells contain a large amount of eosinophilic granular material in the cytoplasm. The cytoplasmic eosinophilic granules were positive for periodic acid Schiff stain. Immunohistochemically, the neoplastic cells were immunoreactive to Melan-A and vimentin. Based on these results, the testicular mass was diagnosed as a granular cell tumor.
