Abstract


Primary lymphomas of the appendix occur in 0.015% of all gastrointestinal lymphomas. The most common manifestation is acute appendicitis secondary to luminal obstruction. The most common is immunophenotype B low-grade non-Hodgkin lymphoma. A 53-year-old male, with a previous three-week surgical history due to acute appendicitis, histopathological report of acute appendicitis and lymphoid hyperplasia. Later, he was admitted, with abdominal pain in the right iliac fossa, an abdominal ultrasound and simple abdominal tomography were performed, with suspicion of residual abscess. Surgical intervention is decided, observing paracecal tumor in the emergency site of the appendix, the tumor is removed. Pathological study that reports an appendicular base infiltrated by mucosa-associated lymphoma. The diagnosis of appendicular tumors is mostly, intraoperatively incidental. It is necessary to have the diagnostic possibility when performing an appendectomy, since it changes the prognosis and treatment of the patient.
