Leprechaunism (Donohue's syndrome) in a low birth weight infant.

A 910 gm infant with leprechaunism, the smallest reported infant with this syndrome, was described. Marked discrepancies were noted between gestational age as assessed by physical examination, bone and dental roentgenographic studies, and renal histology. Radiographic and pathologic features of this syndrome were discussed. Failure to thrive characterized the course of this infant despite adequate caloric intake. The precarious nature of these infants and difficulties encountered in obtaining adequate studies to delineate the cause of this syndrome were emphasized.
