INTRODUCTION: Primary lymphomas of appendix are extremely rare tumors. The incidence is 0.015% ofall gastrointestinal lymphomas. PRESENTATION OF CASE: We present a case of a 75 year-old male patient who presented with acuteabdominal pain in the lower right quadrant and fever. DISCUSSION: The patient received laparotomic appendectomy. The definitive histopathological examina-tion revealed the presence of diffuse large cell B-lymphoma of the appendix. The neoplasms of appendixusually manifest clinically with sign and symptoms of acute appendicitis from luminal obstruction(30–50%). Preoperative diagnosis is difficult and often occurs through histopathological examination. CONCLUSION: Primary appendiceal lymphoma is rare and there are no clear guidelines for ther-apy. Primary surgical resection followed by post-operative chemotherapy showed high efficacy. Thehistopathological examination of all appendectomy is essential.

Abstract

INTRODUCTION: Primary lymphomas of appendix are extremely rare tumors. The incidence is 0.015% ofall gastrointestinal lymphomas. PRESENTATION OF CASE: We present a case of a 75 year-old male patient who presented with acuteabdominal pain in the lower right quadrant and fever. DISCUSSION: The patient received laparotomic appendectomy. The definitive histopathological examina-tion revealed the presence of diffuse large cell B-lymphoma of the appendix. The neoplasms of appendixusually manifest clinically with sign and symptoms of acute appendicitis from luminal obstruction(30–50%). Preoperative diagnosis is difficult and often occurs through histopathological examination. CONCLUSION: Primary appendiceal lymphoma is rare and there are no clear guidelines for ther-apy. Primary surgical resection followed by post-operative chemotherapy showed high efficacy. Thehistopathological examination of all appendectomy is essential.
