Chronic constipation due to Hirschsprung's disease and desmosis coli in a family.

Five members of a family are described, all of whom suffered from chronic constipation and megacolon. Detailed clinical and histologic evaluation of each member revealed that two individuals have histologic evidence of desmosis coli and three have Hirschsprung's disease, one of whom also has desmosis coli. The latter combination has never been described before, either in a family or in a single patient.
