Piebaldisme: une anomalie pigmentaire à reconnaitre: à propos d'un cas et revue de la littérature

Piebaldism is a rare autosomal dominant disorder characterized by an abnormal congenital skin pigmentation causing hypopigmented areas. It is due to an abnormal melanocytes development. It usually affects only the skin, but it may be associated with other anomalies or confused with other differential diagnoses. We report the case of a 5-year old boy with piebaldism having a family history of dermatologic phenotype without other alterations. We here highlight the pathogenesis, clinical manifestations, differential diagnosis as well as the management techniques and new therapeutic trials.
