[Pathologic appendix findings in gynecologic operations].

We report our experiences on three cases with pathologic findings of the appendix vermiformis diagnosed during gynecological operations including mucocele, carcinoid and adenocarcinoma. Mucocele of the appendix is a descriptive term for an abnormal mucous accumulation distending the appendiceal lumen, which can be complicated by pseudomyxoma peritonei. Carcinoid tumours arise from the neuroendocrine system and present a characteristic morphologic picture. Predilicted sites are the appendix and the small bowel. Adenocarcinomas of the appendix that are not associated with mucoceles have a clinical course resembling large bowel cancer. Patients with pathological findings of the appendix may be asymptomatic or present with a palpable right lower quadrant mass and/or pain. We discuss differential diagnosis and present a spectrum of histologic findings.
