Objective: Report of a sertoli cell tumor.
Animal: An eight-year-old intact male terrier.
Procedure: On the basis of clinical signs, laboratory findings, radiographic, ultrasonographic, surgery of tumor, and histopathologic study diagnesis was confirmed.
Results: In clinical examination a spherical, firm mass in caudal part of right hypogastric region was observed. Plain radiography survey showed a round radiopaque mass. Ultrasonography delineated an echogenic spherical mass. This mass and atrophied testicle were
removed. Microscopically, the tumor consisted of masses of elongated, fusiform cells, with eosinophilic, vacuolated cytoplasm and round or ovoid pleomorphic nucleus. The neoplastic cells were arranged in a palisading pattern in which adjacent tumor cells laid parallel to one another with long axes perpendicular to basement membrane.
Clinical implications: The mass on the basis of location, gross and histopathologic charactristics was diagnosed as sertoli cell tumor. J. Fac. Vet. Med. Univ. Tehran. 58,4:373-374,2003.
