  • f 18 fdg pet ct imaging of a Leydig Cell Tumor
    Clinical Nuclear Medicine, 2010
    Co-Authors: Gilho Lee, Jai Hyuen Lee, Won Ae Lee
    Abstract:

    We report the F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) findings of a patient with a testicular Leydig Cell Tumor. A 43-year-old man was referred for whole body FDG PET/CT imaging for health care screening. FDG PET/CT imaging demonstrated the presence of a focal hypermetabolic lesion in the right testicle and no specific findings in other areas. Based on the preoperative impression, right testis-sparing surgery was attempted. The Tumor was pathologically confirmed as a Leydig Cell Tumor.

  • Ovarian sertoli-Leydig Cell Tumor with retiform pattern
    Pathology, 1995
    Co-Authors: Katherine Moyles, Yuen F. Chan, James Hamill, Richard Massey
    Abstract:

    SummarySertoli-Leydig Cell Tumors (SLCT) are sex cord-stromal Tumors which exhibit testicular differentiation. They account for less than 0.2% of ovarian neoplasms in total but comprise 4% of ovarian Tumors in females under 20 yrs of age. The morphological appearance of these Tumors varies more widely than that of any other ovarian Tumor except for the teratomas. Histologically they are now classified into 5 categories: well-differentiated, intermediately differentiated, poorly differentiated, heterologous and retiform. We describe the case of an ovarian Sertoli-Leydig Cell Tumor with retiform pattern in a 7 yr old girl.

  • long term follow up using testicle sparing surgery for Leydig Cell Tumor
    Clinical Genitourinary Cancer, 2013
    Co-Authors: Giorgio Bozzini, Renzo Colombo, Franco Gadda, Giovanni M. Colpi, Ottavio Decobelli, Stefano Picozzi, Jean Palou, Luca Carmignani
    Abstract:

    Abstract Background Our objective was to perform a long-term evaluation of conservative surgical treatment of Leydig Cell Tumors. Patients and Methods A multicenter retrospective clinical study was performed at 6 European centers. Case files of all patients diagnosed with Leydig Cell Tumor and treated with conservative surgery were examined. Patients underwent physical examination, hormone and Tumor marker assays, scrotal and abdominal ultrasonography, chest radiography, and endocrinologic examination. Results From 1987 to 2006, 22 patients with Leydig Cell Tumor underwent conservative surgery. Mean patient age was 35 years (range, 5-61 years). Mean follow-up was 180 months (range, 77-290 months). No local recurrence or metastasis was observed. Patients presented with a palpable testicular nodule (3 patients [13.7%]), a nodule diagnosed by ultrasonography (15 patients [68.2%]), gynecomastia (2 patients [9.1%]), precocious pseudopuberty (1 patient [4.5%]), or scrotal pain (1 patient [4.5%]). Diagnosis after frozen section examination was Leydig Cell Tumor in 20 of 22 patients (91%). Mean histologic size of the nodule was 1.11 cm. Follow-up was conducted for all patients every 3 to 6 months, with physical examination, Tumor marker assays, scrotal and abdominal ultrasonography, chest radiography, and computed tomography (CT). No local recurrences or metastases were observed. One hundred percent of patients are still alive with a 100% disease-free survival. Conclusions When diagnosed and treated early, long-term favorable outcomes are seen at follow-up in Leydig Cell Tumors, even with its potential metastatic behavior. In these patients, testicle-sparing surgery proved to be a feasible and safe choice and could be regarded as the first line of therapy.

    Abstract:

    Purpose: We performed a long-term evaluation of conservative surgical treatment of benign Leydig Cell Tumor.Materials and Methods: A multicenter retrospective clinical study was performed at 6 European centers. Case files of all patients diagnosed with Leydig Cell Tumor and treated with conservative surgery were examined. Patients underwent physical examination, hormone and Tumor marker assays, scrotal and abdominal ultrasound, chest x-ray, and an endocrinological examination.Results: From 1987 to 2006, 22 patients with Leydig Cell Tumor underwent conservative surgery. Mean patient age was 35 years (range 5 to 61). Mean followup was 47 months (range 1 to 230). No local recurrence or metastasis was observed. Patients presented with a palpable testicular nodule (3 patients, 13.7%) or a nodule diagnosed by ultrasound (15 patients, 68.2%), gynecomastia (2 patients, 9.1%), precocious pseudopuberty (1 patient, 4.5%) or scrotal pain (1 patient, 4.5%). Three patients were monorchid after contralateral orchiectomy...
