Rare Benign Large Lymphoid Colonic Polyp

Area of Science:

• Gastroenterology
• Pathology

Background:

• Benign lymphoid polyps are uncommon gastrointestinal lesions, primarily affecting the small bowel and less frequently the colon.
• While predominantly observed in pediatric populations, adult cases are rare and often present as polypoid lymphonodular hyperplasia.

Observation:

• A case of a large benign lymphoid polyp (3 cm, Paris 1p) in the transverse colon of a 64-year-old female patient is presented.
• The patient presented with altered bowel habits and anemia, leading to colonoscopic examination.

Findings:

• Histopathological examination, supported by immunohistochemical studies, confirmed the benign nature of the polyp.
• The lesion was successfully excised during colonoscopy.

Implications:

• Benign lymphoid polyps in adults are rare and can pose a diagnostic challenge.
• Misinterpretation as a malignant lesion is a significant concern, necessitating careful histopathological evaluation.
