title: Leukocyte adhesion deficiency mimicking Hirschsprung disease.
abstract: An infant had clinical signs suggestive of Hirschsprung disease as the initial manifestation of leukocyte adhesion deficiency. Chromosome studies showed a deletion of the distal third of the long arm of one chromosome 21, and flow cytometric studies confirmed the defective expression of CD18.
