© 2021 Turkish Journal of Dermatology | Published by Wolters Kluwer - Medknow.Biotinidase deficiency (BD) is an autosomal recessively inherited inborn error of metabolism that causes multisystemic manifestations, including developmental delay, seizures, hypotonia, vision problems, hearing loss, ketolactic acidosis, and various cutaneous findings at the early stages of life. Treatment consists of oral biotin that is effective in the prevention of complications. We present a case of a 4-year-old boy with partial BD with fingertip desquamation that could be resolved by increasing biotin dosage.
