title: Avascular necrosis of bone in dyskeratosis congenita.
abstract: A case of dyskeratosis congenita, a rare X-linked disorder, is presented. The patient had the classic triad of cutaneous findings: reticulated hyperpigmentation, nail dystrophy, and leukoplakia. In addition, a previously unreported finding developed, avascular necrosis of bone without systemic steroid therapy. Recognition of this disorder is important because pancytopenia and malignancy develop in up to 50 percent of patients.
