We reported the case of a 35-year-old man with Klinefelter's syndrome and a malignant Leydig cell tumor of the testis. Bilateral gynecomastia and right testicular enlargement led the patient to seek medical assistance. Despite initial orchidectomy two years later the patient developed lung and iliac lymph node metastases. The tumor appeared to be refractory to chemotherapy and to hormonal treatments including op'DDD. Finally, the patient died within 20 months of developing metastases. Leydig cell tumor is an exceedingly rare tumor, especially when associated with Klinefelter's syndrome. This association as well as presentation, pathologic features, hormonal abnormalities, clinical course and response to therapy of malignant Leydig cell tumors are discussed.

Adrenocortical carcinoma (AC) is a rare tumor of poor prognosis. Its treatment by o,p'DDD remains a reference after initial surgery. Two galenic forms were recently available in France: Lysodren and Mitotane AP-HP. As Lysodren got a European registration in april 2004, Mitotane is no more produced. O,p'DDD is an adrenolytic and cytotoxic agent. It also reduces the hormonal secretion in AC. Its blood level must reach a therapeutic window (14-20 mg/l) to be effective and to limit toxicity. It is given orally three times a day (3 grams a day for Lysodren and 6-12 grams a day for Mitotane. Its posology is adapted according to serum levels of o,p'DDD and tolerance. Side effects are essentially gastrointestinal (GI), neurologic and hepatic. Five patients (four with AC and one with a metastatic Leydig cell tumor of the testis) were treated by Lysodren. Three patients had early Lysodren discontinuation due to toxicity (skin rash, weight loss, GI toxicity). Studies of combination with other treatments as chemotherapy and targeted drugs are warranted. Surgery is an important part of metastatic disease treatment.
