Superior cure rates to conventional surgery, combined with the potential benefit of sparing healthy tissue, have established Mohs micrographic surgery (MMS) as one of the pillars of skin cancer treatment in recent decades.

The number of Spanish hospitals offering MMS, using either the fresh-tissue technique or slow Mohs, is increasing. In 2013, the Foundation of the Spanish Academy of Dermatology and Venereology (AEDV), together with academy's working group on Surgical Dermatology, Laser, and Cutaneous Oncology (GECIDOC), launched the Spanish Mohs Surgery Registry (REGESMOHS) to compile quantitative and qualitative data on the use of MMS in different regions of Spain.

The article by De Eusebio-Murillo et al.1 in this issue of Actas Dermo-Sifiliográficas presents the results for 1796 MMS cases included in the registry up to January 2016. The authors describe, along with other data, key findings related to resource planning, such as type of anesthesia, surgical technique, hospitalization, number of MMS stages, and surgery duration. All dermatologists planning to perform MMS at their hospital should be acquainted with information on the current state of MMS in Spain.
