A<unk>  cyst can resemble a dermoid cyst, a kind of teratoma (germ cell tumor).  In particular, a<unk>  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.
