VARGAS-VARGAS, Renier; JIMENEZ-SOLANO, Mildred  e  GONZALEZ-BRENES, Mauricio. Clinical case review: Appendicular mucocele, in a male patient, under 40 years of age, athlete. Acta méd. costarric [online]. 2023, vol.65, n.4, pp.225-228. ISSN 0001-6002.

Clinical case of a 35-year-old male patient, an athlete, known to be healthy, who presented a clinical history with indeterminate gastrointestinal symptoms, who underwent complementary studies, detecting a fusiform lesion with a cystic appearance, with serous content, approximately 9cm, belonging to the ileocecal appendix. Initially, due to the findings in the studies carried out on our patient, an appendiceal mucocele was suspected. According to the theory, the appendicular mucocele originates from an obstruction of the ileocecal appendix, which causes a retrograde accumulation of mucinous material and this causes a dilation of the appendicular lumen, becoming a cystic mass. With this presumptive diagnosis, appendectomy with right hemicolectomy was performed. The surgical approach chosen for this case is open versus laparoscopic surgery, due to the risk of mucinous cystadenocarcinoma. Subsequently, the lesion is sent for a pathological study, where a low-grade mucinous neoplasm of the appendix is evidenced.
