Patient 8, a 25-year-old male, had no family history of cutaneous anomalies. His cutaneous anomalies were localized over the trunk and the limbs, particularly on the right (Figure ). The stature was 181 cm (75th percentile). The right upper limb diameter was 2 cm larger as compared with the left; the right lower limb diameter was 4 cm larger. Lower limb length discrepancy was 5 cm (the right side was longer). There was mild involvement of the right hemiface. Left kyphoscoliosis was present (20 degree of Cobb). The man attended school with good scores. No seizures had been recorded.
Patient 6, a 20-year-old male with no noticeable familial cutaneous anomalies, was first referred for a diagnostic work-up regarding his cutaneous manifestations, which were diffuse, as patches, and primarily found on his left side. He had been first referred at age 3 years due to his severe psychomotor delay and for generalized tonic-clonic seizures. The EEG, at that age, revealed spike and wave discharges, prevalent in the frontal regions. Moderate cognitive delay was present. At his most recent physical examination, his stature was 175 cm (50th percentile): his left upper limb was 3 cm larger than the right, and the left lower limb 6 cm larger than the right. The left lower limb was 2.5 cm longer than the right. The ears were bilaterally large and cupped with an enlargement of the left hemiface. Mild right kyphoscoliosis was recorded. Brain MRI was normal. Skin biopsy was not performed.
