Summary
Primary appendiceal lymphoma, a rare non-Hodgkin lymphoma, typically presents as acute appendicitis. This case highlights an unusual presentation with hematuria and abdominal pain, emphasizing the need for broader differential diagnoses.
Area of Science:
- Gastrointestinal Oncology
- Surgical Pathology
- Hematology
Background:
- Primary appendiceal neoplasms are rare, found in 0.5%-1.0% of appendectomy specimens.
- Appendiceal Burkitt's lymphoma is exceptionally rare, accounting for 0.015% of gastrointestinal lymphomas.
- Most appendiceal lymphomas are B-cell non-Hodgkin lymphomas, predominantly affecting males, with acute appendicitis as the common presentation.
Purpose of the Study:
- To report a rare case of primary appendiceal lymphoma.
- To describe an atypical clinical presentation of appendiceal lymphoma.
- To underscore the importance of considering rare diagnoses in abdominal pain presentations.
Main Methods:
- Case report detailing clinical presentation, diagnostic workup, and pathological findings.
- Review of relevant literature on primary appendiceal lymphoma.
Main Results:
- A rare case of primary appendiceal lymphoma was identified.
- The patient presented with hematuria and abdominal/back pain, atypical for appendiceal lymphoma.
- Pathologic evaluation confirmed a B-cell non-Hodgkin lymphoma of the appendix.
Conclusions:
- Primary appendiceal lymphoma can present with unusual symptoms beyond acute appendicitis.
- Hematological malignancies should be considered in the differential diagnosis of unexplained abdominal pain and hematuria.
- Further research into rare appendiceal malignancies is warranted.

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
01:22Appendicitis-I: Introduction
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...
