Pathology

 paraneoplastic dysmotility
 Hirschsprung disease
 hypertrophic pyloric stenosis
 chronic intestinal pseudo-obstruction
 slow transit constipation

Absence or altered distribution of the interstitial cells of Cajal (ICCs) has been described in association with intestinal pseudoobstruction in adults. Abnormalities of the ICCs in intestinal pseudoobstruction should be considered early in the diagnostic workup of children with intestinal pseudoobstruction. (19040916)
