Mohs Micrographic Surgery



Mohs surgery is a highly effective and highly specialised technique for the removal of skin cancer.
Microscopically controlled surgery or Mohs micrographic surgery involves removing the tumour in layers, designing a map of the extracted area and studying the entire piece under the microscope to assess whether sufficient has been removed, both at the surface and in depth. This will achieve two main objectives: it ensures complete tumour removal reducing the number of recurrences, and secondly it avoids unnecessary removal of healthy tissue in areas such as the face, thus improving the final aesthetic result. 
The recurrence percentage rate significantly decreases with Mohs surgery compared to conventional surgery, being less than 1% compared to 10% in a primary basal cell carcinoma and being 2-3% compared to over 20% in a recurrence.
Basal cell carcinoma is the most common malignant tumour in humans. Habitually it does not mestasise, however if not removed completely it may recur and progress, occasionally invading deeply. Mohs micrographic surgery is considered the treatment of choice for recurrent basal cell carcinomas and certain basal cell carcinoma varieties such as: those located on the face, around the eyes, mouth, nose and ears, areas where the tumour may be invasive. It is also the treatment of choice for determined more aggressive histological variants (morpheaform pattern, microinvasive pattern, perineural infiltration pattern) as well as recently excised basal cell carcinomas where the pathology report indicates positive surgical margins..
In addition to basal cell and squamous cell carcinomas, this type of surgery should be considered as first choice in other skin tumours such as dermatofibrosarcoma protuberans, and Merkel cell carcinoma.
