Pathology and Microbiology
We discuss a case of 25 year old male who was evaluated for primary infertility following marriage. He had no previous history of urogenital complaints or abnormalities. In fact, his past medical history was unremarkable. On examination epididymal masses were found. Semen analysis showed azoospermia. Right epididymal mass was surgically excised. Histopathology showed an epididymal neoplasm composed of simple and complex papillary processes lining and filling the ducts. The tumor cells were clear and positive for cytoplasmic glycogen. Immunohistochemistry was also supportive. Diagnosis of clear cell papillary cystedenoma was made based on histopathological and immunohistochemical features.
