Abstract
We recently encountered a case of cystadenoma of the appendix with structual dysplasia. A 71-year-old woman was operated on for acute appendicitis because of ileocecal pain, tenderness in the ileocecal region, muscular defense, Blumberg's sign and tumor-like resistance. However, she was found to have a mucocele of the appendix. Ileocecal resection was performed.
The mucocele of the appendix was sausage shaped and measured 12×5×5cm. It was yellowish white and glossy. The wall was elastic hard. The inner surface was rough and yellowish white. The cavity of the mucocele was filled with a gelatinous substance and was comunicated to the internal cavity of the caecum.
Pathologically, it was diagnosed as a cystadenoma of the appendix with structual dysplasia, suggesting the possibility of a potential carcinoma.
