Lymphoid Polyps (Focal Lymphoid Hyperplasia) of the Colon in Children

Lymphoid polyps (focal lymphoid hyperplasia) of the colon are rare in children. These lesions are benign, but must be differentiated from malignant lymphomas. Grasp biopsies of the lesion are inadequate for this purpose and the polyp should be submitted in toto for pathologic examination. No treatment other than local excision is warranted. Two cases are presented and the literature is reviewed.

Lymphoid hyperplasia of the colon in children. Roentgen observations.

Lymphoid hyperplasia of the colon has been identified in aircontrast studies of the colon in 19 infants and children, the majority of whom presented with rectal bleeding. In each, multiple umbilicated polypoid lesions have been observed. Umbilication in multiple polyps in the colon appears to be diagnostic of lymphoid hyperplasia and differentiates it from juvenile and other polyps in children. This benign lesion probably represents the normal response of lymphoid tissue in children to a variety of stimuli. There is no evidence that the rectal bleeding is caused by the lymphoid hyperplasia.

Diseases of the Colon in Children

Constipation, rectal bleeding and rectal prolapse in children are often overtreated. Prompt and proper management of imperforate anus plays a large role in the eventual outcome. The importance of detecting anomalies of the urinary tract is stressed, together with adequate postoperative care to prevent fecal impactions.Hirschsprung's disease may masquerade as intestinal obstruction in the newborn period. Rectal biopsy establishes the diagnosis by demonstrating the absence of ganglion cells in Auerbach's plexus in the distal segment of the colon. Colostomy is indicated, with closure of the stoma and reconstruction of the colon when the child is one year of age.

Radiologic Diagnosis of Polyps of the Colon in Children

Because of the importance of early and accurate recognition of polypoid lesions of the colon, in order to prevent death from cancer, the emphasis in radiologic diagnosis of colonic polyps has been upon the adult patient (2, 4, 8, 10, 11). The polyps found in childhood are not precancerous (6), except in familial multiple polyposis, and bleeding per rectum is the chief clinical problem. The rigors of preparation and the co-operation needed from the patient in the performance of a barium-enema study make the direct application of adult procedures awkward in children. This report presents the experience in The Montreal Children's Hospital from 1946 to 1959 with polyps of the large intestine and describes a simple and accurate method of radiologic diagnosis. Radiologic Examination The method of radiologic search for polyps of the colon is basically that described by Christie, Coe, Hampton, and Wyatt (4), modified to permit examination of the entire mucosa. It was found that several enemas over a short time wi...

Polyps of the colon in children.

Adenomatous polyps of the colon are sessile or pedunculated, and single or multiple. If multiple, they may be few and scattered or so numerous and diffuse that they virtually replace the lining of the colon. The most significant feature of polyps of the colon in adults is the fact that they are known precursors of adenocarcinoma. From this fact stems the generally accepted view that colonic polyps in adults should be removed. Although adenomatous polyps sometimes occur in the colons of children, carcinoma of the colon is rare in pediatric practice. Gross, with the considerable experience of the Children's Hospital in Boston at his disposal, describes only one case, that of a girl 12 years of age, who had polyposis of the colon associated with an adenocarcinoma of the rectum. The present study of colonic polyps in children was carried out in the hope that data might emerge to guide
