This is a report on two brothers with the Hermansky-Pudlak syndrome who developed pulmonary fibrosis. In the first, a gradual course lasting 13 years was observed, the patient finally died of long-standing colitis. His brother died of progressive respiratory failure 15 months after the subjective onset of the disease. Immunosuppressive therapy proved ineffective.

The Hermansky-Pudlak syndrome (HPS) is a triad of tyrosine-positive albinism, platelet dysfunction, and the deposition of an abnormal ceroid-like pigment in the tissues. Complications of the syndrome, such as pulmonary fibrosis, renal failure, and cardiomyopathy, have been described. Granulomatous colitis has been documented in several families with the HPS. The bowel disease of the HPS is a unique type of inflammatory bowel disease with clinical features suggestive of idiopathic ulcerative colitis and pathologic features suggestive of Crohn's disease. Analogous to the presentation of Crohn's disease with perianal and perirectal involvement, we describe the occurrence of perianal disease and a perirectal abscess in a 29-yr-old woman with HPS and mild granulomatous colitis.

We present the radiologic features of four patients proven to have Hermansky-Pudlak syndrome. All four patients had evidence of pulmonary involvement characterized by a progressive, diffuse, bilateral interstitial fibrosis. Extensive bullous changes were seen in one patient. Two patients with evidence of diffuse colitis exhibited an asymmetrical pattern of focal, superficial, and deep ulcerations similar to that of Crohn's disease. The association of these radiographic abnormalities with albinism, ocular abnormalities, bleeding diathesis, and Puerto Rican ancestry establishes the diagnosis.

The Hermansky-Pudlak syndrome, a triad of albinism, platelets lacking dense bodies, and storage of ceroid-like material in tissues, occurs approximately once in 2,000 northwestern Puerto Ricans. The manifestations of storage disease are variable and include granulomatous colitis, restrictive lung disease, kidney failure, and cardiomyopathy. The autofluorescent material stored in the Hermansky-Pudlak syndrome is histochemically similar to that stored in neuronal ceroid/lipofuscinosis. The material in neuronal ceroid/lipofuscinosis contains dolichols, which are components of lysosomes, and patients show increased urinary excretion of dolichols. This study of 49 patients with the Hermansky-Pudlak syndrome found that urinary dolichol levels are increased in those patients with evidence of ceroid storage in the kidneys but are not elevated when storage occurs in tissues other than the kidneys. The excretion of ceroid was not influenced by the saturation state of dietary fat. A defect in processing of membranes of lysosomes, melanosomes, and dense bodies may be involved in the syndrome.

The Hermansky-Pudlak syndrome consists of tyrosine-positive albinism, a defect in the second phase of platelet aggregation, and widespread accumulation of a ceroidlike pigment in tissue. Pulmonary fibrosis has also been reported. In this paper, we describe two families with documented Hermansky-Pudlak syndrome in which four members, two from each family, developed granulomatous colitis. This adds another disease entity to those associated with this syndrome. We discuss possible connecting links between these disease expressions.

Colitis is an important cause of abdominal pain and diarrhoea and is the main cause of blood and mucus in the stool. The inflammation can be due to infectious or to non-infectious causes, most commonly ulcerative colitis and Crohn's disease. However, a wide variety of rarer causes of colitis also present in childhood. These include colitis or enterocolitis secondary to Hirschsprung's disease and metabolic disorders (which include Hermansky-Pudlak syndrome, glycogen storage disease type 1b and pellagra). Primary inflammation of the colon is seen in microscopic and collagenous colitis, ulcerating enterocolitis of infancy, allergic colitis and autoimmune enteropathy. The histological pattern of each of these diseases has a characteristic picture and separates them from each other from ulcerative colitis and Crohn's disease. The pathophysiology of these rare forms of colitis in childhood is not clear; but in the future they may give us an insight into the pathogenesis of large bowel inflammation, particularly when the colitis occurs secondary to an established disease.

Hermansky-Pudlak syndrome is a rare, inherited, autosomal recessive disease. Diagnosis is based on a triad of signs: oculocutaneous albinism, a hemorrhagic tendency due to a platelet disorder, and an accumulation of lipopigments in different organs, particularly the medullary macrophages. We describe a child with the characteristic findings of this syndrome, which often goes unrecognized because of the discrete nature of the cutaneous and hemorrhagic manifestations. This diagnosis is important because of the risk not only of hemorrhage but also of granulomatous colitis and long-term pulmonary fibrosis.

Hermansky-Pudlak syndrome (HPS) is a rare autosomal recessively inherited disease with oculocutaneous albinism, hemorrhagic diathesis, and multisystemic deposition of ceroid lipofuscin. We report a case with all symptoms characteristic of HPS. The patient was a mentally retarded albino with mild bleeding diathesis, and her course was complicated by granulomatous colitis refractory to medical treatment and progressive, fatal pulmonary fibrosis.

A 55-year-old man had oculocutaneous albinism and a history of frequent bruising following minimal trauma. The simultaneous occurrence of these features was first described by Hermansky and Pudlak in 1959. The Hermansky-Pudlak syndrome follows an autosomal recessive trait and is most frequently found in Puerto Rico and in the Swiss alps. It consists of the triad phenotype of hypopigmentation, prolonged bleeding time due to platelet storage pool deficiency and accumulation of ceroid pigment in lysosomal organelles. Other serious features are pulmonary fibrosis and granulomatous colitis. The disorder is caused by mutations in the HPS1 gene on chromosome 10q23. The HPS1 gene product is involved in the trafficking of melanosomes, platelet dense bodies, and lysosomes.

Hermansky-Pudlak syndrome (HPS) is an autosomal recessive disorder characterized by oculocutaneous albinism (OCA), platelet storage pool deficiency, and ceroid lipofuscin deposition. Sequelae including pulmonary fibrosis, colitis, and hemorrhagic diathesis can impact obstetric management. An 18-year-old primigravida with OCA was diagnosed during pregnancy with Hermansky-Pudlak syndrome by DNA analysis. Uneventful vaginal delivery occurred at term following prophylactic platelet transfusion. Women of northwestern Puerto Rican descent with OCA should be offered testing for HPS. Identification of affected individuals may permit optimal obstetric management.
