Testicular epidermoid cyst

Abstract

Epidermoid cyst of the testis is a benign, non-teratomatous tumour. It is often possible to make the diagnosis pre-operatively, combining typical sonographic features with normal biochemical tumour markers. The accurate pre-operative diagnosis will allow for testis-sparing surgery and prevent unnecessary orchiectomy. An 11-year-old boy with testicular epidermoid cyst who presented with pain in testis was presented in this report.

“…The central echogenic center seen at ultrasound corresponds to the lower signal intensity zone seen at MRI and is thought to represent the keratin debris. [4]…”

Testicular epidermoid cyst: A rare case

“…[ 2 ] An “onion ring” or “bull's eye” appearance describing the alternating hypo- and hyperechogenic layers consistent with of keratin deposition within the lumen may also be seen. [ 6 10 ] MRI can help in the diagnosis showing hyperintense T1-weighted areas representing intracystic lipid aggregates of proteinaceous cystic contents. Ultimately, the histological analysis is required to confirm the diagnosis and is done intraoperatively through frozen section.…”

“…No reported cases of local recurrence or metastasis have been found in the literature, thus, testis-sparing excision has recently become the treatment of choice. [ 6 ] This treatment method requires partial orchiectomy followed by intraoperative frozen section to rule out malignancy. If the pathology is reported as benign the procedure can be terminated, however, if the final pathology describes a teratoma or malignant pathology, radical orchiectomy is required.…”

“…[ 4 ] Epidermal cysts, also, lack testicular intraepithelial neoplasia and carcinoma in situ of the surrounding seminiferous tubules of teratomatous lesions and 80%–100% of germ cell tumors. [ 2 6 ] Therefore, this theory has been rejected by the current literature. A second supported theory is described as a metaplasia of epidermal cells from the rete testis secondary to an obstruction of the epidermal tube.…”

Lesión quística testicular en un lactante: consideraciones diagnósticas y terapéuticas

“…No obstante, en las últimas décadas la cirugía conservadora, definida como enucleación o tumorectomía con preservación del parénquima sano, se ha posicionado como el estándar de tratamiento de tumores testiculares en menores de 12 años, puesto que se ha descrito una tasa de benignidad cercana al 80% (16,17). En casos de lesiones quísticas que se presumen benignas, el abordaje quirúrgico de elección es la enucleación (2,18), dado el mínimo riesgo de recidiva, metástasis o atrofia residual (8,11,19,20,21,22).…”
