Sertoli-Leydig cell tumor https://www.malacards.org/card/sertoli_leydig_cell_tumor ONCOTREE:SLCT MONDO:0002479 A sex cord-gonadal stromal tumor consists of leydig cells; sertoli cells; and fibroblasts in varying proportions and degree of differentiation. Most such tumors produce androgens in the Leydig cells, formerly known as androblastoma or arrhenoblastoma. Androblastomas occur in the testis or the ovary causing precocious masculinization in the males, and defeminization, or virilization (virilism) in the females. In some cases, the Sertoli cells produce estrogens. DOID:2997 MESH:D018310 UMLS:C0206723 MEDGEN:61669 GARD:0009967 testicular sex cord-stromal neoplasm
