Beare–Stevenson cutis gyrata syndrome

Beare–Stevenson cutis gyrata syndrome is a rare genetic disorder characterized by craniosynostosis (premature fusion of certain bones of the skull, sometimes resulting in a characteristic 'cloverleaf skull'; further growth of the skull is prevented, and therefore the shape of the head and face is abnormal) and a specific skin abnormality, called cutis gyrata, characterized by a furrowed and wrinkled appearance (particularly in the face and on the palms and soles of the feet); thick, dark, velvety areas of skin (acanthosis nigricans) are sometimes found on the hands and feet and in the groin.
