The use of the flexible scalpel for minimally invasive and minimally scarring surgery: a case series of four patients with large scalp tumors.

Reconstruction of the scalp after Mohs surgery can pose dilemmas for the dermatologic surgeon, especially for extensive tumors. The authors present a unique technique for removing large in-situ epidermal tumors of the scalp during Mohs surgery in four patients. Although invasive tumor was removed with a standard No. 15 scalpel, the extensive epidermal component of the tumor was removed through the mid-dermis using the flexible scalpel. This technique allowed the superficial defect to heal by second intention. The results showed minimal scarring and hair regrowth in what could have been large defects requiring complex reconstruction.
