BACKGROUND: Young women with nondescript abdominal pain can be difficult to diagnose. Although extrapelvic endometriosis is infrequent, we have treated 7 patients over the past 3 years with endometriosis in the abdominal wall, inguinal canal, or surgical incisions as the etiology of their symptoms. PATIENTS AND METHODS: We reviewed the medical records of patients whose final pathology report confirmed a diagnosis of extrapelvic endometriosis. Seven women who were treated at the University of Rochester Strong Memorial Hospital from May 1, 1991 through April 30, 1994 were identified. RESULTS: All patients were premenopausal with no history of pelvic endometriosis. In 4 patients, symptoms were cyclical. Surgical excision was initially curative in 5 patients. Two women required reexcision. The diagnosis of endometriosis was established at exploration by gross appearance and by frozen section. CONCLUSIONS: Endometriosis should be included in the differential diagnosis of a symptomatic mass in a celiotomy scar, the abdominal wall, or the inguinal canal. Principles of management include obtaining an accurate diagnosis and performing an adequate excision to prevent recurrence.
