Mohs surgery beyond the face: scalp, hands, and lower legs
The technique is best known for facial skin cancer, but tight scalps, working hands, and slow-healing shins each change the plan in their own way.
Mohs micrographic surgery is best known as a facial procedure, and the central face is where its precision earns the most attention, as covered in why the nose, ears, and lips are prime Mohs territory. But a meaningful share of Mohs cases happen elsewhere: on the scalp, the backs of the hands, and the lower legs. The cancer biology is the same in these locations. What changes is the anatomy around the tumor, and each site brings its own practical wrinkles that are worth understanding before the appointment.
Why these sites qualify for Mohs at all. The decision framework does not change off the face: Mohs is favored where tumors recur more often, where borders are hard to define, or where there is little spare tissue, the same logic laid out in when Mohs is the right choice, and when it is not. The scalp, hands, feet, ankles, and shins all appear in the appropriate-use criteria that guide the choice, because these areas combine heavy sun exposure with anatomy that punishes an incomplete excision (American College of Mohs Surgery). A small, low-risk cancer on the back or shoulder, by contrast, is often still treated perfectly well with a standard excision.
The scalp: tight skin and hidden borders. Scalp skin has very little stretch, so even a modest defect can be difficult to close in a straight line, and repairs there lean more often on flaps, grafts, or healing by second intention, the options described in reconstruction after Mohs surgery. Hair complicates things in both directions: it can hide a tumor's true edge before surgery, and it usually needs a small trimmed area on the day. Two reassurances help. Hair regrows around most repairs, though a graft or a scar line itself will not grow hair, and the numbing and staged rhythm of the day are identical to facial Mohs.
The hands: function first. On the backs of the hands and fingers, the concern is not cosmetic so much as mechanical: tendons and joints sit close beneath thin skin, and a repair must preserve a full range of motion. Surgeons plan closure lines around how the hand moves, sometimes splint the area briefly, and may ask patients to limit gripping and lifting with that hand for a week or two. Squamous cell carcinoma is the more common cancer here, and it deserves timely treatment on the hands, where it behaves somewhat more assertively than on the trunk (American Academy of Dermatology).
The lower legs: the slow-healing zone. Shins and ankles have the least forgiving circulation of any common Mohs site, especially in older patients and anyone with swelling, vein disease, or diabetes. Wounds there close more slowly, open more easily, and carry a higher infection risk, which is why surgeons often favor grafts or second-intention healing over tight closures, and why aftercare instructions lean heavily on elevation, compression when advised, and patience. The warning signs that deserve a call are the same ones reviewed in signs of infection after Mohs surgery, watched a little more closely here. A lower-leg repair that takes six or more weeks to settle is not failing; it is healing on that region's schedule (MedlinePlus: after surgery).
What patients can do differently by site. For the scalp, arrange the week so hats and helmets are optional, and expect a bulkier dressing than a facial repair. For the hands, plan around typing, tools, and lifting for a week or two, and mention your occupation to the surgeon, since it genuinely changes the repair choice. For the lower legs, build elevation into the day, sofa time with the leg up is part of the treatment, and take the walking-not-running guidance seriously, echoing the pacing in Mohs recovery and scar care.
The encouraging summary is that Mohs travels well. The cure rates that made the technique the standard on the face hold elsewhere, and the site-specific differences are matters of repair and recovery, not of whether the cancer can be cleared. Knowing what your particular patch of skin asks of the process turns each of these locations from a surprise into a plan.
