Late onset Darier´s disease in a genetically predisposed individual: a case report

Abstract

Keratosis follicularis also called as Darier's disease, is a rare autosomal dominant cutaneous disease. It is characterized by greasy keratotic sometimes crusted red to brown papules and plaques over seborrheic areas and in flexures with nail abnormalities. It is well established that the disease begins between the ages of 6 and 20 years, with a peak onset during puberty. The disease tends to manifest early, especially with the family history of the disease. Hereby, we report a case of Darier's disease with a special interest in its late onset presentation despite having significant family history of the disease, along with clinicopathological and dermoscopic features. We also highlight the use of non-invasive investigative technique of dermoscopy as a tool to diagnose the disease.
