[Mohs micrographic surgery: 27 year experience in the Northeast of Mexico].

INTRODUCTION Skin cancer treatment includes surgical and non-surgical techniques. Among surgical techniques, Mohs micrographic surgery permits a complete evaluation of surgical margins with maximal tissue sparing. MATERIAL AND METHODS Retrospective review of dermatology database of skin cancer cases treated with Mohs surgery at University Hospital Dr. José Eleuterio González from 1988 to 2015. RESULTS A total of 546 cases were included, of these 289 (52.93%) corresponded to women and 257 (47.07%) to men. Mean age at presentation was 64.3. Most tumors (63.2%) corresponded to infiltrative basal cell carcinoma and the majority were located on the nose and cheek; 9.7% of cases corresponded to recurrent tumors. A mean of 1 Mohs stages was used in 56%, with a mean of 2 sections in 23.6%. Cutaneous flaps were used in 47.7%, representing the predominant reconstruction technique. CONCLUSION Mohs surgery has emerged in one of the dermatology reference centres in the North of the country as one of the surgical techniques for the treatment of aggressive carcinomas with high risk of recurrence.
