Resolution of Pseudoainhum with Acitretin Therapy in a Patient with Palmoplantar Keratoderma and Congenital Alopecia

We report on a patient with palmoplantar keratoderma (PPK) and congenital alopecia (CA) who presented with pseudoainhum and resultant constricted hand mobility. With several months of treatment with acitretin, 25 mg daily, the patient's pseudoainhum resolved, with improvement in hyperkeratosis. We therefore post acitretin as an option for treatment of pseudoainhum, a condition for which reconstructive surgery is considered the conventional treatment.1
