title: Spermatocytic seminoma.
abstract: A case of spermatocytic seminoma is described. The lesion illustrates the characteristic macroscopic and microscopic pathology of this relatively rare tumour, and is the largest recorded example. The long history of 15 years draws attention to the slow growth pattern and excellent prognosis. Chromosomal analysis, hitherto undescribed for spermatocytic seminoma, reveals moderate aneuploidy of tumour cells.
