[Microhematuria secondary to mucocele and appendicular cystoadenoma].
Appendiceal mucocele is a rare entity consisting of cystic dilatation of the appendix as a result of increased mucus production. Most cases are related to the presence of a cystadenoma. This appendiceal neoplasm is frequently associated with other extraintestinal and colonic tumors and therefore adequate abdominal examination is necessary. The clinical presentation is nonspecific and varies from asymptomatic forms to abdominal discomfort and, less frequently, to urological manifestations. We describe the case of a woman with hematuria associated with an appendiceal mucocele. Only a few cases have been reported in the medical literature. The treatment of choice of cystadenoma is surgery and simple mucocele cannot be macroscopically differentiated from cystadenoma and cystadenocarcinoma. Survival in patients with appendiceal cystadenoma is excellent. The 5-year survival rate is reduced by at least half in patients with cystadenocarcinoma associated with pseudomyxoma peritonei.
