[Large cell calcifying Sertoli cell tumour: A case report].

A 19-year-old male Caucasian, without prior medical history, noticed a painless right testicular mass. Physical examination revealed neither gynecomastia nor abnormal skin pigmentation. Serum alpha-fetoprotein, β-HCG and testosterone levels were normal. Sonography depicted an intratesticular diffusely hyperechoic lesion with acoustic shadowing. The patient underwent right orchiectomy. Histology revealed a benign large cell calcifying Sertoli cell tumour. This tumour is rare and may be associated with genetic abnormalities.
