MUCINOUS CYSTADENOMA OF APPENDIX CONCOMITANT WITH PERITYPHLIC GRANULOMA

We describe a case of mucinous cystadenoma of the appendix with perity phlic granuloma. The patient developed a hard palpable mass in the rig ht lower quadrant and barium enema inducted irregular bowel wall at th e cecum. Based on a preoperative diagnosis of carcinoma of the appendi x, we performed a laparotomy. On operation, we found a tumor mass in t he region of the appendix; the mass adhered strongly to the retroperit oneum and cecum. Right hemicolectomy was carried out on a diagnosis of carcinoma of the appendix. Microscopic examination revealed mucinous cystadenoma of the appendix with perityphlic granuloma. Mucinous cysta denoma in the appendix is a rare tumor. In this patient, the tumor was accompanied by granuloma formation in adjacent tissues because of muc in expelled from the appendix. This case emphasizes that granuloma for mation can make of difficult to differentiate mucinous cystadenoma in the appendix from cancer.
