Compromiso del apéndice cecal por linfoma folicular grado 2. Reporte de un caso de presentación clínica atípica

The involvement of the appendix by lymphomas, both primarily or secondarily, is extremely rare; primary lymphomas account for less than 0.02% of gastrointestinal neoplasm. We present the rare case of a patient who debuts with low gastrointestinal bleeding as the main symptom. Colonoscopy found an extra mucosal tumour on the posterior aspect of the ceccum and bleeding from the appendicular orifice. Primary appendicular tumour is confirmed on multislice computed tomography and laparoscopic right hemicolectomy is performed. The patient had an uneventful postoperative course and was discharged on the 6th postoperative day. The pathology report shows a infiltration of the cecal appendix by grade 2 follicular lymphoma.
