Noniatrogenic neonatal gastric perforation is a rare and life-threatening condition whose etiology is often unclear. Interstitial cells of Cajal act as gastrointestinal pacemaker cells and express the proto-oncogene c-Kit. Six new cases were identified at our institution which presented with no mechanical, pharmacologic, or otherwise medical-related intervention prior to rupture. The number of interstitial cells of Cajal in nonnecrotic muscularis propria from five random high-power fields per specimen was compared using immunohistochemical stains for c-Kit. The authors show that a lack of interstitial cells of Cajal in the stomach musculature may be implicated in the development of noniatrogenic gastric perforation (p = 0.008). Further large-scale studies, including molecular and genetic analysis, may help to better understand this phenomenon.
