“…In a series of 71.000 patients, Collins [1] noted an inci dence of 0.082%. Following the presumably first descrip tion in 1882 by Berger [2], about 250 cases of mostly welldifferentiated [3] adenocarcinomas of the appendix have been reported [4], but only 10 have become symptomatic as a result of bladder involvement (table 1) [5][6][7][8][9][10][11][12][13]. The differential diagnosis of adenocarcinomas of the bladder includes primary tumors associated with exstro phy, persistent urachus, schistosomiasis, endometriosis, nonfunctional bladder and transplantation [14] as well as secondary bladder involvement from tumors originating from the female inner genitals or the rectosigmoid [15].…”

We report a case of an appendix carcinoma invading the urinary bladder. In contrast to other bowel tumors invading the bladder, history and symptoms were consistent with a primary bladder tumor. This is due to the unique anatomical position of the appendix where the tumor did not hinder passage of bowel contents or cause melena. Findings on physical examination as well as diagnostic imaging and transurethral resection were inconclusive. Consideration of local progression of an appendix carcinoma is an important differential diagnosis. In contrast to other vesical or extravesical T₄ tumors, the appendix carcinoma offers a good chance for resection en bloc by right-sided hemicolectomy and partial cystectomy.

“…Rarely the tumor can invade the abdominal wall with an enterocutaneous fistula or the urinary bladder with an enterovesical fistula, as shown in this case. International literature report only nine cases of vesico-appendiceal fistulas derived from mucinous appendiceal adenocarcinomas until present data 1,2,3,4,8 . This type of tumor usually perforates before diagnosis and may spread to the peritoneal cavity, producing mucinous intraperitoneal ascites, resulting in the pseudomixoma peritonei 7 .…”

BACKGOUND: A rare case of vesicoappendiceal fistula secondary to mucinous adenocarcinoma of the appendix is presented. CASE REPORT: A 62-year-old man with a one year history of recurrent urinary tract infections. After two months he developed pneumaturia and fecaluria. An abdominal and pelvic computed tomography demonstrated a trans-mural mass in the posterior wall of the bladder with a vesicoenteric fistula leading to the terminal ileum. Laparotomy revealed a tumor arising from the appendix contiguous with the bladder posterior wall. The bladder was opened and a large fistula and tumor on the posterior bladder wall near the trigone was identified. Frozen pathological analysis showed a mucinous adenocarcinoma. En-bloc right hemicolectomy and partial cystectomy, preserving bladder trigone was performed. After manipulating the tumor, grossly leakage of mucinous materials occurred into the pelvic cavity. A peritoneal washing with a mytomicin solution at 42º C was then performed, to prevent peritoneal seeding. The patient had a prolonged postoperative ileus and was discharged at the 15th day. Five months after the procedure the patient was recieving chemotherapy with 5-fluoracil and leucovorin and there was no signs of recurrent disease. CONCLUSION: The presentation with vesico-appendiceal fistula is extremely rare with only a few cases reported in the literature. Knowledge of different types of neoplasm and appropriate treatment allows the surgeon to provide patients optimal care referring to specialized centers whenever appropriate.

“…To date, only eighteen cases have been reported including ours [3,[9][10][11][12][13][14][15][16][17][18][19][20][21]. Appendiceal adenocarcinoma most often presents in patients during their 50 s-60 s, significantly older than patients with appendicitis.…”

The appendiceal diseases, particularly appendicitis, are the most common disorders in the digestive system localized at the right lower quadrant area. However, appendiceal carcinoma with vesico-appendiceal fistula is a rare clinical phenomenon. Lacking specific symptoms, appendiceal carcinomas with fistula formations are often misdiagnosed as acute appendicitis cases. The purpose of this study is to increase awareness of appendiceal neoplasms and appendicovesical fistulas. We reported our experiences in three complex cases related to digestive and urological systems, and reviewed the literature on diagnosis with various X-ray imaging techniques for this lesion. In this report, the first case failed to be diagnosed. The other two patients with appendicovesical fistulas secondary to appendiceal adenocarcinomas were successfully detected with computed tomography (CT) and cystoscopy. The patients recovered after right hemicolectomies and en bloc partial cystectomies and survived without tumor metastasis up to 7-year follow-up. In conclusion, a combined use of CT imaging and endoscopy techniques provides an accurate diagnostic alternative for appendicovesical fistula secondary to appendiceal adenocarcinoma.
