ABSTRACT
A 40-year-old woman was admitted to our hospital with the chief complaint of miction pain. MRI showed fundal wall thickening of the bladder in contact with the appendix. Under cystoscopy, redness of the mucous membrane was found in the posterior wall of the bladder. Therefore, laparo-appendectomy with partial cystectomy was performed. Microscopically, adenocarcinoma cells were observed in the lumen of the appendix, invading the wall of the urinary bladder at the fundus of the appendix. We performed laparo-ileocecal resection for a regional lymphadenectomy. Thus, the patient was diagnosed with adenocarcinoma of the appendix[V, type 3, 16×7 mm, tub2, pT4b(SI, urinary bladder), int, INF b, ly0, v0, pN0, cM0, pStage â ¡]. The patient has been receiving adjuvant chemotherapy using capecitabine for 6 months. There was no evidence of recurrence after 9 months of follow-up.
