BASSO, Marcelo Pandolfi et al. Appendicular endometriosis as a cause of chronic abdominal pain alone in the right iliac fossa: case report and literature review. J. Coloproctol. (Rio J.) [online]. 2012, vol.32, n.1, pp.79-82. ISSN 2237-9363. http://dx.doi.org/10.1590/S2237-93632012000100012.
Endometriosis is a disease characterized by the presence of ectopic endometrial glands and stroma. Although its etiology is undefined, it is suggested to be a result of coelomic metaplasia, retrograde menstruation, to provide a genetic component, or to be one that occurs due to blood or lymphatic spread. The involvement of the gastrointestinal tract is common. However, appendicular endometriosis is a rare condition. It is usually asymptomatic. Recurrent pain in the right iliac fossa is an unusual clinical manifestation. There are no non-invasive complementary tests to confirm the diagnosis. Laparoscopy is the main option for research, due to its diagnostic and therapeutic features. A histopathological examination is necessary for the diagnosis. Although surgical and drug therapies have special indications, the combination therapy showed lower symptom recurrence. This study reports a case of appendicular endometriosis that was diagnosed and treated in the service of Coloproctology of the Base Hospital at Faculdade de Medicina of São Jose do Rio Preto. There is also a literature review about this situation.
