MOHS Micrographic Surgery

Mohs micrographic surgery (also known as Mohs chemosurgery) is a state-of-the-art treatment for skin cancer in which the diseased area is removed with the accuracy and precision of a microscope. Of all techniques to remove skin cancer, Mohs micrographic surgery has the highest cure rate and minimizes the extent of scarring. Mohs surgery is a one day, outpatient treatment which is generally reserved for use only with certain skin cancers. Those that are large, have recurred following conventional treatment, or those found in certain anatomic locations such as the central face are very effectively treated with this technique. Mohs surgery is utilized most often for the treatment of basal cell carcinoma, squamous cell carcinoma, and lentigo maligna (an early form of melanoma usually occurring on the face). However, the Mohs technique is also useful for other, less common forms of skin cancer, including sebaceous carcinoma, merkel cell carcinoma, atypical fibroxanthoma, microcystic adnexal carcinoma and dermatofibrosarcoma protuberans.
