Evaluation of nail involvement in patients with chronic cutaneous graft versus host disease: a single-center study from Turkey.

Although graft versus host disease (GVHD) is associated with a myriad of cutaneous signs, nail involvement is rarely mentioned in the literature. This study was conducted at the Department of Dermatology and The Bone Marrow Transplantation Unit of Hematology. All patients were examined clinically for presence of nail abnormalities. Severity of nail involvement was assessed as mild or severe. Of 28 patients diagnosed with chronic cutaneous GVHD, 14 had nail manifestations. Longitudinal ridging was the most frequently observed nail change on both the fingernails and the toenails. Severe nail changes such as ptergyium and onicoatrophy were noted in a few patients. As a result we could not find any relationship between nail changes and clinical severity but there was a relationship between nail changes and duration of disease. Nail manifestations could be responsible for considerable morbidity.
