A case of an inguinal dermoid cyst presenting as an incarcerated inguinal hernia in a 18-year-old boy is reported. A differential diagnosis of masses in the inguinal region is discussed and includes not only hernias but also gynecologic and vascular lesions. Dermoid cysts must be included in the differential diagnosis. Histologically, these cysts are characterized by an external lining composed of squamous epithelium with an underlying fibroconnective tissue containing hair follicles, sebaceous, eccrine, and apocrine glands. The presence of all the skin appendages in these cysts distinguishes them from epidermoid and sebaceous cysts. The lack of structures foreign to skin differentiates them from dermoids (benign cystic teratomas) in the ovarian, testicular, retroperitoneal, and sacrococcygeal region.
本文报道了一例18岁男孩腹股沟皮样囊肿表现为嵌顿性腹股沟疝的病例。文中讨论了腹股沟区肿物的鉴别诊断，包括不仅有疝，还有妇科及血管性病变。皮样囊肿必须纳入鉴别诊断。从组织学上看，这些囊肿的特征是外层由鳞状上皮构成，其下方的纤维结缔组织含有毛囊、皮脂腺、小汗腺和大汗腺。这些囊肿中所有皮肤附属器的存在使其有别于表皮样囊肿和皮脂腺囊肿。缺乏皮肤以外的结构则使其有别于卵巢、睾丸、腹膜后及骶尾部的皮样囊肿（良性囊性畸胎瘤）。
