[Leydig cell tumor with pronounced virilization]

A report is given on the rare case of a hormonactive Leydig cell-tumor in a 52-year-old patient. In spite of virilization symptoms of many years' standing, it was only because of multiple troubles with a great uterus myomatosus that she was admitted to the hospital. An ovarian tumor existing at the same time, turned out to be histologically a mere hilus cell-tumor with a strong nucleus polymorphy. In consideration of the danger of a malignant degeneration (borderline case), the patient was included in our tumor follow-up control programme.
