A rare case of epithelioid sarcoma (ES) of the penis is presented. The patient, a 35-year-old man, was initially treated as having Peyronie's disease, but the subsequent appearance of a subcutaneous nodule displayed a 'distal-type' ES. At immunohistochemical phenotypification, the tumor was positive for vimentin, cytokeratins and epithelial membrane antigen (EMA), as well as for some other multidirectional antibodies, including a membranous reaction for CD99. The review of 11 similar cases so far reported in the literature led to the conclusion that the clinicopathological characteristics of penile ES are basically the same as those of tumors in more classical locations: the age at diagnosis ranged from 23 to 43 years, the interval between first manifestations and diagnosis averaged 37 months (delayed diagnosis being common because of the slow growth rate and the harmless appearance of the lesion), the typical sign was a superficial nodule or mass, usually accompanied (better preceded) by urethral stenosis, dysuria and erectile disturbances. Total or partial penectomy was the treatment of choice in most patients, but lack of adequate follow up did not permit any definitive conclusion to be reached regarding its efficacy.
