REPORT OF A CASE  A 5-month-old girl was referred to us for evaluation of several cutaneous lesions noted immediately after birth. The family had no history of similar lesions.On the arms, torso, thighs, and labia majora were several depressed lesions in a linear and cribriform configuration (Figs 1 and 2). In these areas the skin was thin and pink, and telangiectases were visible. The left pectoralis major muscle was not palpable, and the left nipple appeared lower than the right. The left arm was shorter than the right arm. Hypoplasia was noted on the second and third metacarpal bones of the left hand, and the fingernails on that extremity were thinned and longitudinally split. She also presented with syndactyly of the second and third toes of the right foot. The head was small and had a peculiar round configuration.A skin biopsy specimen was obtained from an atrophie lesion on the arm. The specimen was stained with hematoxylineosin (Fig 3).What is your diagnosis?
