Report of a child with disseminated ganglioneuromatosis of the gut. The complexity of the intestinal nervous system malformation is proved by histochemical, histoenzymological and ultrastructural studies. The malformation is characterized by: hyperplasia and hypertrophy of enteric plexus and nerves bundles in the meso, high acetylcholinesterase activity, aplasia of the sympathetic innervation with the exception of perivascular plexus, qualitative and likely quantitative integrity of the endocrine digestive system.
