Rectal tonsil, a rare lymphoid tissue proliferation in the rectum, presents as benign lymphoid hyperplasia. It requires differentiation from mucosa-associated lymphoid tissue lymphomas for accurate diagnosis.
Area of Science:
- Gastroenterology
- Pathology
- Oncology
Background:
- The rectal tonsil is a rare reactive proliferation of lymphoid tissue in the rectum.
- Benign lymphoid hyperplasia of the rectum exhibits specific histological features, including large lymphoid follicles with active germinal centers.
Observation:
- This paper details a case of rectal tonsil in a 59-year-old woman.
- Endoscopic ultrasound imaging findings are presented for this rare condition.
Findings:
- Histological examination reveals benign lymphoid hyperplasia, distinct from malignant lymphomas.
- The lesion must be differentiated from polypoid mucosa-associated lymphoid tissue lymphomas.
Implications:
- Accurate differentiation is crucial for appropriate patient management.
- Understanding the imaging characteristics aids in diagnosing this rare rectal finding.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants.
