Fine needle aspiration cytology of spermatocytic seminoma. Report of a case.
The clinical, radiologic, cytopathologic and histologic features of a case of spermatocytic seminoma in a 56-year-old man are reported and discussed. The cytologic findings in fine needle aspiration (FNA) smears suggested a diagnosis of spermatocytic seminoma, which was confirmed by subsequent histopathologic studies. The case suggests that spermatocytic seminoma can be suspected and distinguished from other types of seminoma and germ cell neoplasms by FNA cytology. The following criteria appear to be the most useful in making the cytodiagnosis: the presence of three different types of cells (large, medium and small), a clean background, an absence of a lymphoid component and "tigroid" substances and the relative paucity and clumping tendency of the neoplastic cells in the smears.
