Mohs surgery more effectively cleared LM, despite the fact that higher-risk lesions were assigned to this technique.
When local excision is employed as a treatment modality for lentigo maligna, 0.5 to 1 cm margins are routinely used. To assess whether this approach is adequate to prevent high rates of recurrence, investigators compared wide local excision with Mohs surgery.
Hou et al performed a retrospective analysis of cases of lentigo maligna treated at the Mayo Clinic from 1995 to 2005. A total of 269 lesions were treated with wide local excision (5 mm margins) and 154 with Mohs surgery. Five-year recurrence rates were 1.9% in the Mohs group and 5.9% in the group that underwent wide local excision. This was not a randomized trial; the tumors treated with Mohs tended to be relatively higher risk, larger head and neck lesions with indistinct clinical mar…
