Congenital skin fossae about the shoulder

Congenital fossae, skin pits, or dimples can form about the shoulder. Little has been written about congenital supraspinous fossae or dimples. They are thought to result from the catching of tissues between a sharp bony post and the uterine wall. The skin and structures become compressed and adherent, and when the pressure is released, the surrounding parts remain tied down, forming small pits or dimples. I report on a congenital fossa in the scapular region of an infant who cried each time the arm was abducted. This congenital fossa did communicate with and adhered to the scapula. Excision of the fossa with its surrounding scar tissue about the scapula plus gentle manipulation gave free motion to the shoulder.
