Metastatic carcinoid diagnosed at laparoscopic excision of pelvic endometriosis

Carcinoid tumors are uncommon lesions that arise from the intestinal tract or ovaries. Metastatic carcinoid was found in a 35-year-old woman who underwent laparoscopic excision of pelvic endometriosis. The primary tumor was in the distal appendix, and metastatic carcinoid coexisted with endometriosis in both pelvic sidewall specimens. This unusual situation is another reason to consider excision of presumed pelvic endometriosis. It is important to be aware of other uncommon gastrointestinal and pelvic conditions, such as the occasional carcinoid in the appendix or ovary.
