Fine-needle aspiration cytology (FNAC) findings are described in a case of spermatocytic seminoma occurring in a 52-yr-old male, involving the left testis. The smears showed three populations of cells (small, medium, and large), with a preponderance of medium-sized cells showing visible nucleoli. The background was clean, in contrast to the "tigroid" substance seen in classical seminoma. Low mitotic rate and absence of lymphocytes were the other features helpful in diagnosis. Because of these distinct morphological features, a preoperative diagnosis of spermatocytic seminoma was possible, with subsequent confirmation on histopathology. The case is being reported because of the rarity of this tumor, and because there have been only a few reported cases of FNAC diagnosis.
