Patient 7, a 22-year-old male, had no family history of cutaneous lesions. At physical examination, his height was 182 cm (75th percentile). The hypopigmented lesions were widely diffused over the trunk and with greater prevalence on the right side (Figure ). Left upper limb diameter was 2.5 cm larger than the right, whereas left lower limb diameter was 6 cm larger. The difference in the lower limb length was 4 cm (left > right). Right hemiface was importantly involved. Cognitive delay was present. An EEG revealed generalized spike and wave discharges, and the patient experiences epileptic seizures of the generalized tonic-clonic type. Fundus examination was normal. Convergent strabismus was noticed. Short and broad nose, macrocrania, and left kyphoscoliosis (20 degree of Cobb) were also recorded. Brain MRI was normal.
Patient 5 was a 18-year-old female who first came to our observation at the age of 24 months due to language delay. Her psychomotor development was also delayed. Convergent strabismus was present, with no anomalies at fundoscopy. Mild dysmorphic features were present, including epicanthic folds and hypotelorism. Physical examination revealed that her height was 175 cm (in the 90th percentile). The hypopigmented lesions were widely diffused in the trunk, particularly on the right side. The right upper limb diameter was 4 cm larger than the left side, and the right lower limb diameter was 7 cm larger and 3 cm longer than the left. Also, the right hemiface was involved by the disturbed growth. EEG and brain MRI were unrevealing. Left kyphoscoliosis was recorded with 10 to 15 degree of Cobb scale.
