[Testicular epidermoid cyst: uncommon lesion of difficult preoperative diagnosis]

Intratesticular epidermoid cysts are rare tumours that constitute one percent of all testicular masses. They are bening lesions that make differential diagnosis from malignant testicular tumours difficult. The absence of serum markers elevation and ultrasound imaging could support these lesions being bening epidermoid cysts, and in that case, conservative surgery is adequate. We present the case of a 22 years old patient who complains of a left testicular mass. In this case ultrasound diagnosis was non-specific and a left radical inguinal orchiectomy was performed.
