To report a case of Hermansky-Pudlak syndrome. A seven-year-old boy presented with marked generalized hypopigmentation, ocular exodeviation and nystagmus. He had history of easy bruising. Examination revealed green irides with marked transillumination, hypopigmented fundi and foveal hypoplasia. Further investigations disclosed platelet storage defect with adenosine diphosphate deficiency and abnormal aggregation compatible with Hermansky-Pudlak syndrome.
