Abstract
Dyskeratosis follicularis (Darier’s disease, DD) is rare autosomal dominant disease characterized by hyperkeratotic papules that coalesce into plaques and occur primarily in seborrheic or intertriginous areas. Associated findings include nail abnormalities. A 3-year-old boy presented with porcupine-like appearance for 2 years. The lesion from the back was taken for light microscopy and electron microscopy. He was treated with acitretin (0.31 mg/d to 0.66 mg/d) for 8 years. Light microscopy and electron microscopy showed that the typical features of DD. The patient show good respond to the treatment. During 8 years treatment, the patient had dry mouth and pruritus. The skeletal abnormalities didn’t happen in the patient. The serum lipid profile, liver function and renal function within normal lever after treatment. Our findings showed that porcupine-like appearance is a unique pattern of DD. Acitretin may be a useful therapeutic agent in children with DD and less likely to cause skeletal problems.
