A 71-year-old woman was admitted to our hospital with the tumor at the right lower abdominal area.
On barium enema study, a deformity from the cecum to the ascending colon was demonstrated and the appendix itself was not visualized. The colonoscopy disclosed that the submucosal tumor like lesion was visible from the cecum to the ascending colon, the orifice of the appendix was not detected. The tumor infiltrated into the ascending colon, and the biopsies histologically showed well differentiated adenocarcinoma with product of mucin. The CT and the ultrasound study revealed the cystic tumor at the right lower abdomen. These findings suggested that the tumor was suspected the cystic type appendeceal cancer.
The curative right hemicolectomy with lymphnode dissection was performed. The preoperative diagnosis of the appendiceal cancer is extremely difficult because of its growing pattern, but in our case histopathological diagnosis was obtained by colonoscopic study with biopsy.
