NCIt synonyms : Testicular Leydig Cell Neoplasm; Leydig Cell Tumor of the Testis; Leydig Cell Tumor of Testis; Leydig Cell Neoplasm of the Testis; Leydig Cell Neoplasm of Testis;

NCIt definition : A sex cord-stromal tumor that arises from the testis and is characterized by the presence of cells that resemble the successive stages of development of Leydig cells. It usually presents as a painless testicular mass. Gynecomastia is present in approximately thirty percent of the cases. Libido may be decreased. In children, precocious puberty may be present.
