Representative Café-au-lait Spots Seen in McCune-Albright Syndrome. A spectrum of spots is shown; Panels A & B demonstrate “classic” spots that both respect the midline and display “coast of Maine” borders. Panel C shows a very unusual spot seen in a child with MAS and neonatal Cushing syndrome. While the spot respects the midline, the borders are smooth and the spots alternate from left to right in a harlequin pattern. Panel D depicts a very large spot with relatively smooth borders seen in a patient with relatively little FD. Panel E demonstrates a spot that clearly does not respect the midline.
