CONGENITAL CHYLOTHORAX IN SIBLINGS

We describe two cases of congenital chylothorax in siblings with impor tant differences from previously described familial cases. Our finding s support the likelihood of an autosomal recessive inheritance in some cases of this condition. rather than X-linked recessive inheritance, which has also been suggested. Autopsy findings from one of these case s and others previously described suggest that the pathophysiological mechanisms involved may be variable.
