Cutaneous Endometriosis after Abdominal Myomectomy

ABSTRACT

Endometriosis is the aberrant presence of endometrial tissue outside the uterine cavity. We report a case of cutaneous endometriosis which developed on the scar of a uterine myomectomy in a 35-year-old female. The patient presented with a bean-sized, oval-shaped, erythematous nodule, which was located where a drain tube had been inserted. During her first visit to our clinic, she felt slight pain upon light touch to the lesion. She was not menstruating at this time. The lesion had been getting bigger and she reported that the pain was aggravated during menstruation. Diagnosis was confirmed by histopathologic examination, which showed multiple endometrial glands with decidualized stroma, and hemosiderin pigment. Many dermatologists are not familiar with cutaneous endometriosis. Therefore, we present this case as a good example which shows pathognomonic symptoms and characteristic histopathologic findings of cutaneous endometriosis.
