Sertoli cell tumour of the testis is a rare tumour currently classified in three types: general, with large calcifying cells and sclerosing. These three forms differ for their potential malignancy and association with extragonadal involvement. We report on our experience with 2 cases. The first was a calcifying Sertoli large cell tumour of the testis with an unusual ultrasound finding. The second was a combination of the general and the sclerosing form. Whenever the histology examination shows no malignant features, we suggest local excision as the gold standard therapy, as it allows the testicular parenchyma to be preserved. An accurate follow-up is obviously mandatory.
