Malignant Leydig cell tumour of the testis

Leydig Cell Tumor of the Testis. New Cases and Review of the Current Literature

Leydig cell tumors are the most frequent non-germ cell tumors of the testis, accounting for 1-3% of all testicular tumors. They present most commonly as a testicular mass or with endocrine symptoms. We report three new cases of Leydig cell tumori that presented in different forms. The relevant literature is reviewed and the management of these tumors is discussed.

Eleven patients with testicular leydig cell tumors: clinical, imaging, and pathologic correlation

We present the sonographic and magnetic resonance imaging findings of Leydig cell tumors in a series of patients, along with a brief review of the literature. We evaluated the sonographic features of 11 cases of Leydig cell tumors, including echogenicity, size, margins, and patterns of vascularity. The magnetic resonance imaging characteristics of 9 patients were also assessed, with special attention to the appearance of the tumors on T2-weighted imaging and postcontrast T1-weighted imaging. Seven tumors were hypoechoic, and 4 were almost isoechoic. Ten patients showed various patterns of hypervascularity in the tumors, combined in some cases with feeding vessels. One case presented with a single feeding vessel. The tumors showed homogeneous or heterogeneous low signal intensity on T2-weighted imaging and marked enhancement on postcontrast T1-weighted imaging. The small size of these tumors, the various patterns of vascularity on color and power Doppler sonography, and the marked enhancement on postcontrast T1-weighted imaging are considered valuable but generally nonspecific for identification of these tumors.

Hemorrhagic shock caused by rupture of an intra-abdominal leydig cell tumour: case report

The rupture of an intra-abdominal testicular neoplasm is a rare cause of acute abdomen and massive intra-abdominal haemorrhage. We report the case of a 70-year-old male presenting a massive intra-abdominal bleeding caused by a Leydig cell tumour in an undescended testis. The clinical details and pathology of this rare testicular tumour are discussed.
