A 5.5-year-old girl was brought to our hospital with a complaint of disproportionate overgrowth and lengthening of the right leg accompanied by marked hypopigmented lesions over the trunk and legs, which reportedly had become noticeable by 2-weeks postpartum and gradually increased and spread. She was born to non-consanguineous parents and had been under monitoring for delayed speech. On examination, her height and weight were 110 cm (10th to 25th percentile) and 23 kg (75th to 90th percentile), respectively. The dermatological examination was remarkable for hypopigmented patches following the Blaschko lines over the trunk and both legs, more prominently on the right leg (, ), which was thicker and longer (~2 cm) than the left (). Apart from these findings, the systemic examinations, routine haemogram and biochemical tests, and magnetic resonance scans of the cranium and lower extremities were normal. When the Denver Developmental Screening Test was administered for speech delay, it was graded as ‘delayed’, correlating with the age of 3.5 years. After consultation with the dermatology department, a skin biopsy was considered unnecessary.
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.
