Cutaneous Endometriosis: Report on Two Different Surgical Presentations and the Role of FNAC

Abstract

Background: Cutaneous endometriosis is a rare entity that can occur after gynecologic surgery as well as spontaneously. This condition can resemble general conditions in patients with indications for surgery and, thus, such patients are commonly referred to general surgeons instead of gynecologists. Cases: This article covers two cases of cutaneous endometriosis with two different surgical presentations diagnosed by fine-needle aspiration cystology (FNAC) and confirmed by histopathologic examinations. One woman, age 50, presented with an umbilical nodule with rapid enlargement, and the other woman, age 25, presented with an abdominal scar from a caesarean section performed 8 months prior. FNAC smears revealed high cellularity with, groups of glandular and stromal cells accompanied by some inflammatory cells and hemosiderin-laden macrophages in a hemorrhagic background. Both patients had excision of the mass. Results: During a 1-year follow-up, the patients' recoveries were unevenful and there were no recurrences. Conclusions: Presentation of cutaneous endometriosis can be varied and FNAC can play a role in diagnosing the condition quickly, obviating the need for biopsy. (J GYNECOL SURG 29:339)
