Mohs micrographic surgery may be used for melanoma in situ beyond excision margins

Mohs micrographic surgery was used effectively to treat melanoma in situ exceeding traditional excision margins of 5 mm, according to published study results.

Researchers examined the long-term outcomes of 882 primary or recurrent melanoma in situ tumors (mean patient age, 62 years; 52.4% male) located on the trunk or proximal extremity and treated with Mohs micrographic surgery (MMS), and compared the outcomes with those of historical controls. Surgical margin intervals determined complete excision rates. Read more
