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, p...

Hermansky-Pudlak syndrome is a rare autosomal recessive disorder characterized by excessive bleeding post surgery. Here we reported such a case and reviewed the clinicopathological features and our current understanding of this rare congenital disorder.

OBJECTIVES To evaluate the spectrum of foveal architecture in pediatric albinism and to assess the utility of spectral-domain optical coherence tomography (OCT) in ocular imaging of children with nystagmus. METHODS Spectral-domain OCT imaging was performed on study subjects in 3 groups: subjects with ocular albinism (OA) or suspected OA with foveal hypoplasia, with nystagmus, and with or with...

BACKGROUND Many platelet functions are dependent on bioactive molecules released from their granules. Deficiencies of these granules in number, shape or content are associated with bleeding. The small size of these granules is such that imaging them for diagnosis has traditionally required electron microscopy. However, recently developed super-resolution microscopes provide sufficient spatial r...

Objective. The aim of this paper is to report the case of a patient diagnosed with Hermansky-Pudlak syndrome, as a result of bleeding diathesis. Clinical Presentation and Intervention. A 23-year-old male presented with recurrent epistaxis and, upon physical examination, was found to be remarkable for albinism and suborbital ecchymosis. The absence of dense bodies in the platelets was demonstrat...

Inherited platelet function disorders (IPFDs) encompass a heterogeneous group of haemorrhagic diseases caused by congenital defects of platelets function affecting various elements of the platelet physiology (membrane receptors, intraplatelet signalling proteins, granules), and leading to different clinical manifestations (1–3). Platelets have three types of secretory granules that differ in th...
