Hermansky Pudlak syndrome: an unusual form of procto-colitis.

Hermansky-Pudlak syndrome (HPS) is a rare autosomal recessive disorder consisting of oculocutaneous albinism, platelet dysfunction and systemic complications associated with lipofuscin deposition in the reticuloendothelial system. HPS has been associated with a granulomatous enterocolitis with pathologic features suggestive of Crohn's disease. It remains uncertain if HPS represents a truly distinct form of granulomatous enterocolitis. We report a series of two patients with HPS treated in Puerto Rico, and the results from medical and surgical intervention for gastrointestinal disease. Our experience with HPS patients has shown the difficult management of perineal disease similar in the management of Crohn's. However, complications from the bleeding diathesis necessitate caution during surgery and potential anesthesia complications. Furthermore, avoidance of a perineal wound is preferred, and when possible, ileostomies have fewer complications than colostomies as they do not involve the small bowel.
