Introduction:
Becker's nevus is a dermatological disease sometimes associated with a malformation such as hemifacial bone dysplasia.
Observation:
A 11-year-old male patient presented with a delayed growth of the left maxillary and dental impactions. At 15 years of age, Becker's nevus appeared on the upper torso, both shoulders and cheeks. Le Fort I segmented osteotomy with an iliac bone graft was complicated because of maxillary dysplasia.
Discussion:
The chronology of our patient's cutaneous and maxillary abnormalities was similar to previously reported cases. Conversely, the Becker's nevus-bone dysplasia association has been reported only twice. It may not be a coincidence and could belong to a Becker's nevus syndrome.
