The series comprises 6 patients (mean age, 21 years) who presented with an
epidermoid cyst of the testis between 1991 and 1998. Pre-operative ultrason
ography suggested the presence of a testicular cancer in 3 patients who und
erwent a radical orchidectomy. The ultrasound successfully predicted the tr
ue diagnosis in 3 patients who had a wedge excision of the cyst together wi
th a cuff of normal surrounding tissue. All patients are free of disease wi
th a mean follow-up of 3 years.
With increasing awareness of the condition coupled with accurate pre-operat
ive radiological imaging, local excision of an epidermoid cyst with preserv
ation of the remainder of the testis is now a feasible and rational alterna
tive to more radical surgery.
