RESUMO

BACKGROUND: Appendectomy remains one of the most common emergency operations. Recent research supports the treatment of uncomplicated appendicitis with antibiotics alone. While nonoperative management of appendicitis may be safe in some patients, it may result in missed neoplasms. We present a case of acute appendicitis where the final pathology resulted in a diagnosis of a Burkitt-type lymphoma. CASE PRESENTATION: An 18-year-old male presented to the emergency department with 24 h of right lower quadrant pain with associated urinary retention, anorexia, and malaise. Past medical history was significant for intermittent diarrhea and anal fissure. He exhibited focal right lower quadrant tenderness. Workup revealed leukocytosis and CT uncovered acute appendicitis with periappendiceal abscess and no appendicolith. Laparoscopic appendectomy was performed and found acute appendicitis with associated abscess abutting the rectum and bladder. Pathology of the resected appendix reported acute appendicitis with evidence of Burkitt-type lymphoma. A PET scan did not reveal any residual disease. Hematology/oncology was consulted and chemotherapy was initiated with an excellent response. CONCLUSIONS: Appendiceal lymphomas constitute less than 0.1% of gastrointestinal lymphomas. Primary appendix neoplasms are found in 0.5-1.0% of appendectomy specimens following acute appendicitis. In this case, appendectomy allowed for prompt identification and treatment of an aggressive, rapidly fatal lymphoma resulting in complete remission.
