Mohs micrographic surgery is a specialised surgical technique used to treat the most common malignant skin tumours, such as basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). It is also suitable for the treatment of various other skin cancers.

It is considered the gold standard for skin cancer surgery due to its higher cure rates compared with conventional surgical techniques.

Mohs surgery is particularly suitable for tumours located on the face and other functionally important areas (e.g., scalp, hands and feet, genital region, shins). Unlike standard excision, it preserves healthy surrounding skin to the greatest possible extent.

It is recommended for fast-growing (aggressive) tumours, recurrent (relapsing) tumours, and primary tumours with a high risk of recurrence.

After excision of the skin tumour, a microscopic histopathological examination of the entire deep surface and all peripheral margins is performed. If the analysis reveals residual tumour cells, the surgeon continues with an additional stage of targeted excision, removing tumour remnants only from those specific areas where cancer is still present.

This technique ensures complete tumour removal while maximally preserving surrounding healthy tissue, resulting in a smaller scar and an improved cosmetic outcome.

The procedure is performed under local anaesthesia. A preoperative consultation is essential for planning the treatment, during which the extent of surgery and scarring will be discussed.

Recovery lasts 7 to 14 days. Postoperative discomfort is mild, and complications are rare.
