Mohs surgery

(redirected from Moh's surgery)

Mohs che·mo·sur·ger·y

a technique for removal of skin tumors with a minimum of normal tissue, by prior necrosis with zinc chloride paste, mapping of the tumor site, and excision and microscopic examination of frozen section of thin horizontal layers of tissue, until all of the tumor is removed. More recently, the preliminary step of chemical necrosis has been omitted.

Mohs surgery

A therapy for broad-based, shallow BCC or SCCs, especially for lesions that are 1–2 cm, recurring or on recurrence-prone sites (nose, eyes, ears), or are aggressive histologic subtypes (e.g., sclerosing (morphoeic) BCC).

The surface of the lesion plus 3–5 mm margin of normal tissue is coagulated with dichloracetic acid, overlaid with a 20% zinc chloride paste and covered with an occlusive dressing. The ZnCl2 fixes the tissue similar to formaldehyde; after 24–48 hours, a “saucer” of tissue is removed and submitted for frozen section analysis to determine sites, if any, of deep tumour extension. Mohs surgery reduces the incidence of recurrent disease while preserving non-involved tissue.

Of prior authorizations tracked at the University of Utah, 39.1% were for nonbiologic therapies, 21.6% were for excisions, 16% were for Moh's surgery, 11% were for biologies, and the remainder was for an array of other procedures or therapies.
In high-risk lesions, Moh's surgery shows the best results regarding local recurrence and appearance of metastases (Motley et al.
Further, amputation has to date been the most preferred method of 'treatment' for plantar SCCs with soft tissue involvement, as the efficacy of Moh's surgery and sentinel lymph node biopsy remain inconclusive (2).
