Hermansky-Pudlak syndrome is a rare, inherited, autosomal recessive di
sease, Diagnosis is based on a triad of signs: oculocutaneous albinism
, a hemorrhagic tendency due to a platelet disorder, and an accumulati
on of lipopigments in different organs, particularly the medullary mac
rophages. We describe a child with the characteristic findings of this
syndrome, which often goes unrecognized because of the discrete natur
e of the cutaneous and hemorrhagic manifestations. This diagnosis is i
mportant because of the risk not only of hemorrhage but also of granul
omatous colitis and long-term pulmonary fibrosis.
