Malignant leydig cell tumor: Clinical, histologic and electron microscopic features

Abstract: A 51-year-old man had a malignant Leydig cell tumor of the testis with elevation of serum estrone and androstenedione as well as urine chorionic gonadotropin. The fine structural features of the neoplasm resembled those of nontumorous Leydig cells as well as cells of Leydig cell adenomas, except for, nuclear pleomorphism, the absence of Reinke's crystals and the infrequency of microvilli. The abundance of smooth surfaced endoplasmic reticulum, well-developed mitochondria with tubular and vesicular cristae were… Show more

“…In some diseases such as Down's syndrome, XX-male syndrome or malignant tumours of Leydig cells, Reinke's crystals are absent. The same goes for stimulated and ectopic Leydig cells (Feldman et al 1982;Mori et al 1978;Sasagawa et al 1995). When infertile patients are concerned, our observations concur with observations of Exaire et al (1982) and Söderström (1986).…”
