Ovarian epidermoid cyst, an extremely rare tumor occurring mostly in older females, is lined by mature stratified squamous epithelium and distinguishable from mature teratoma by the absence of skin adnexae and other tissues. In imaging, these tumors resemble solid tumors, necessitating most patients to undergo oophorectomy to verify malignancy. We herein present the case of an ovarian epidermoid cyst in a pregnant woman who underwent laparoscopic cystectomy after delivery with preserved ovarian function. To the best of our knowledge, this is the first case report of an ovarian epidermoid cyst that was detected during pregnancy and treated with laparoscopic cystectomy. Preservation of ovarian function and application of minimally invasive surgery should be strongly considered in young patients with ovarian epidermoid cysts.
