Abstract

Highlights: Primary lymphomas of appendix are extremely rare tumors. The incidence is 0.015% of all gastrointestinal lymphomas. The neoplasms of appendix usually manifest clinically with sign and symptoms of acute appendicitis. Preoperative diagnosis is difficult and often occurs through histopathological examination, so it is mandatory for all appendectomies. There are no clear guidelines for therapy. Primary surgical resection followed by post-operative chemotherapy showed high efficacy. Abstract: Introduction: Primary lymphomas of appendix are extremely rare tumors. The incidence is 0.015% of all gastrointestinal lymphomas. Presentation of case: We present a case of a 75 year-old male patient who presented with acute abdominal pain in the lower right quadrant and fever. Discussion: The patient received laparotomic appendectomy. The definitive histopathological examination revealed the presence of diffuse large cell B-lymphoma of the appendix. The neoplasms of appendix usually 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 therapy. Primary surgical resection followed by post-operative chemotherapy showed high efficacy. The histopathological examination of all appendectomy is essential.
