Spontaneous cutaneous endometriosis of the mons pubis: Diagnosis, treatment, and review of the literature

Abstract

Background: Cutaneous endometriosis is usually associated with a preceding surgical scar; spontaneous cutaneous endometriosis is rare. We report on a case of spontaneous cutaneous endometriosis of the mons pubis as well as a review of the literature. Case: A 46-year-old woman with no surgical history presented to gynecology clinic with a 6-year history of a mass on the mons pubis causing severe cyclic pain with enlargement during menses. Initial fine needle aspiration biopsy was nondiagnostic; thus, pelvic ultrasound, magnetic resonance imaging, and a core needle biopsy were used to diagnose a mons endometrioma. The lesion was surgically excised with pathology confirming the diagnosis. The patient noted subsequent improvement in her symptoms. Conclusion: Spontaneous cutaneous endometriosis of the mons pubis can be successfully treated via surgical excision.
