Pilonidal cyst differential diagnosis

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [2]

A pilonidal cyst can resemble a dermoid cyst, a kind of teratoma (germ cell tumor). In particular, a pilonidal cyst in the gluteal cleft can resemble asacrococcygeal teratoma. Correct diagnosis is important because all teratomas require surgical complete excision, if possible without any spillage, and consultation with an oncologist.
