Benign nodular lymphoid hyperplasia of colon: a report of two cases.

Benign nodular lymphoid hyperplasia of the colon in children is a rare entity, distinct from lymphoid polyps, and must be differentiated from malignant lymphomas. We report two girls, 9 years old and 5 years old, in whom nodular hyperplasia caused intestinal obstruction. No etiologic cause was found in them. Immunochemistry (Pan B and Pan T) markers in one case showed staining in the respective areas of the lymphoid aggregates. Viral marker studies were not done. Surgical resection was done.
