Abstract
We report a very rare case of multifocal early carcinomas arising from the vermiform appendix. A 32-year-old woman was referred to our hospital with a suspected diagnosis of appendicitis. On admission, a tumor of about 5cm was palpable with tenderness at the right lower abdomen and severe anemia was revealed by the hematological study. Abdominal CT, MRI and Ba enema disclosed a tumor in the cecum that was apparently prolapsing from the orifice of the vermiform appendix on colonoscopy. Histopathologically the tumor was diagnosed as tubular adenoma with atypia. Moreover, abdominal sonography strongly suggested the presence of another tumor in the distal appendix. We performed right hemicolectomy with D3 dissection. The resected specimen showed a polypoid tumor prolapsing into the cecum from the proximal appendix and another subpolypoid tumor in the distal appendix. These tumors were histopathologically diagnosed as multifocal early carcinomas.
