Abstract

Most solitary gastrointestinal (GI) polyps in children are either inflammatory or hamartomatous. Solitary hyperplastic polyp, sentinel polyp and solitary adenomatous polyp have been occasionally diagnosed in adults, but very rarely reported in Korean children. We recently came across a case with adenomatous polyp in the colon, a case with hyperplastic polyp beneath the gastroesophageal junction, a case with hyperplastic polyp in the prepyloric area, and a case with sentinel polyp in the distal esophagus, which are unusual pathologic types in children. These mucosal lesions were diagnosed incidentally during elective endoscopic examinations for GI symptoms. Most polyps do not cause significant symptoms, so the diagnosis might be delayed, especially in children, in whom GI endoscopy is not commonly performed for screening purpose as in the adults.

  Fig. 1 (A) Left: a solitary, non-pedunculated polyp with smooth surface in the rectum. Right: the polyp shows proliferation of irregular dysplastic glands (H&E stain, ×100). (B) Left: there is a non-pedunculated polyp with rough and markedly congested surface beneath the gastroesophageal junction (GEJ) area. Right: the polyp shows hyperplastic foveolar glands, suggestive of hyperplastic polyp (H&E stain, ×100). (C) Left: there is a non-pedunculated polyp with moderate congestion and coarse surface in the prepyloric area. The surrounding antral mucosa is nodular and edematous. Right: the polyp shows hyperplastic foveolar glands, suggestive of hyperplastic polyp (H&E stain, ×100). (D) Left: there is a longitudinal, broad-based polyp with a smooth surface in the GEJ region. Right: the biopsy reveals hyperplastic foveolar glands, suggestive of hyperplastic polyp (H&E stain, ×100).
