PURPOSE Although most Leydig cell tumors are benign, radical orchiectomy is currently considered the standard therapy. We retrospectively analyzed the long-term followup of a series of patients with Leydig cell tumors electively treated with testis sparing surgery. MATERIALS AND METHODS Between November 1990 and December 2005, 17 consecutive patients with Leydig cell tumors underwent testis s...

“Burned out” testicular germ cell tumors are rare, representing involuted primary tumors typically discovered during workup for metastatic disease with associated elevated serum tumor markers. Histologically, a hyalinized scar is seen, often with surrounding intratubular germ cell neoplasia. We report a 24 year-old man who presented with a two-month history of cough, dyspnea, and intermittent t...

AIMS To determine the morphological and immunohistochemical profile of retiform Sertoli-Leydig cell tumours and to compare the observed profile with that of adult rete ovarii. METHODS AND RESULTS Nineteen retiform Sertoli-Leydig cell tumours were studied, eight by immunohistochemistry, and five examples of rete ovarii from adult females were also evaluated immunohistochemically. The patients ...

Leydig cell tumor (LCT) is a rare tumor of the male testicular interstitium. This article provides an overview of the major pathologic manifestations of LCT of the testis; patient characteristics; clinical, radiologic, and laboratory features; prognosis; and management. LCTs of the testis are frequently hormonally active, leading to either feminizing or virilizing syndromes. The tumor is usuall...

A 50-year-old peri-menopausal woman presented with hard palpable mass on her lower abdomen and anemia from heavy menstrual bleeding. Ultrasonography showed a 13×12 cm sized hypoechoic solid mass in pelvis and a 2.5×2 cm hypoechoic cystic mass in uterine endometrium. Abdomino-pelvic computed tomography revealed a hypodense pelvic mass without enhancement, suggesting a leiomyoma of intraligamenta...

Abstract Introduction Leydig cell tumours (LCTs) are rare testicular stromal neoplasms classically presenting with a painless mass or swelling in adults. Symptoms secondary to hypogonadism may occur resulting from the hormonal activity of these tumours. Loss libido is described LCTs conjunction other symptoms; however, no case has reported this as sole feature. Case report We describe 42-year-o...

Leydig cell tumors represent 3% of testicular masses and usually occur in prepubertal boys and men between 30 and 60 years of age. Leydig cell tumors are benign in children but can be malignant in 10% of adults. This case report describes a 41-year-old patient who was diagnosed with a Leydig cell tumor that originated in his right testicle that subsequently metastasized to his liver, lungs, and...
