Abstract:
Epidermoid cysts are rare tumours, which account for 1% of all testicular tumours. Very rarely, they are intrascrotal but extratesticular. We present a rare case of an intrascrotal extratesticular cyst. The triad of findings were sonographic appearance of an onion ring, avascularity on Doppler sonography and negative results of tumour markers; these are highly suggestive of an epidermoid cyst.
