Abstract

Hoyeraal-Hreidarsson syndrome is a rare telomere biology disorder that is recognized as a severe variant of dyskeratosis congenita. We present a Libyan boy with hematologic and neurologic abnormalities with typical dermatologic manifestations of dyskeratosis congenita. Death usually occurs before the age of 4 years as a result of pancytopenia or malignant transformation of mucocutaneous lesions. The boy presented survived longer than 5 years. Early recognition and appropriate genetic counseling are crucial because of the high mortality of this genetic disorder.
