Mohs surgery report: design of an appropriate rhombic flap for a circular defect created by Mohs microscopically controlled surgery.

The rhombic flap is a transposition flap based on exact geometric design. The rhombic transposition principle, however, can be applied to circular as well as to geometric wounds. A method is suggested by which the best rhombic flaps for any specific anatomic site can be generated without conversion of the wound to a rhombic design.
