[A priori benign Leydig cell testicular tumor: enucleation or radical orchidectomy?]

The histological sections of 5 patients treated for clinically benign Leydig cell testicular tumour (LCTT) were reviewed according to histological criteria presumptive of malignancy. The absence of any sign of severity was only verified in a single case, as none of the other tumours could be considered to be strictly benign. In the light of these findings, great caution is required in conservative indications, especially as these tumours, when they are malignant, are particularly serious due to the inevitable diagnostic delay and their absence of radio- or chemo-sensitivity.
