Epidermoid Cyst of Testis: A Report of 3 Cases

Abstract

We report 3 cases of simple epidermoid cyst of the testis. These tumors often are mistaken clinically for malignancy. Conservative surgical treatment with preservation of the testis is desirable when preoperative ultrasound reveals a well demarcated cystic nodule confirmed by histological frozen sections.

Extratesticular Epidermoid Cyst with Extension into the Pelvis

“…Epidermoid cysts of the testis occur predominantly between the ages of 20 and 40 years, but may also be found in childhood (7). A right-sided location, very few symptoms such as localized discomfort and a diameter ranging from 1 to 3 cm have been reported (1).…”

Epidermoid Cyst of the Testis

“…Within the advent of ultrasound of the testis, a reliable method is now available for determining whether a mass is intratesticular or extratesticular and for establishing whether a testicular mass is com posed of a cystic or solid component [4][5][6]. Sonograms are also helpful in ruling out multiple testicular lesions [4], Malignant testic ular tumors generally reveal decreased echogenicity within the testi cle, which is usually enlarged [6], but there are also tumors demon strating focal areas of mixed echogenicity [16], More aggressive forms tend to invade the tunica distorting the testicular contour.…”

“…According to few reported cases [6][7][8], the sonogram of a simple testicular or an epidermoid cyst demonstrated well-defined walls, even an echogemc rim due to calcification. The center of a simple testicular cyst was free of echoes [8], while the center of two epider moid cysts gave either only minute internal echoes [6] or high inten sity echoes [7].…”

“…The center of a simple testicular cyst was free of echoes [8], while the center of two epider moid cysts gave either only minute internal echoes [6] or high inten sity echoes [7]. This is possibly due to the varying echogenic prop erties of the inner amorphous mass.…”
