Epidermoid cysts of the testis: the case for conservative surgery

The series comprises 6 patients (mean age, 21 years) who presented with an epidermoid cyst of the testis between 1991 and 1998. Pre-operative ultrasonography suggested the presence of a testicular cancer in 3 patients who underwent a radical orchidectomy. The ultrasound successfully predicted the true diagnosis in 3 patients who had a wedge excision of the cyst together with a cuff of normal surrounding tissue. All patients are free of disease with a mean follow-up of 3 years. With increasing awareness of the condition coupled with accurate pre-operative radiological imaging, local excision of an epidermoid cyst with preservation of the remainder of the testis is now a feasible and rational alternative to more radical surgery.
