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.

Keywords: Acute appendicitis; Appendix; Case report; Lymphoma.
