Systematic review of Mohs micrographic surgery in children: Identifying challenges and practical considerations for successful application.

BACKGROUND

Few data exist to guide the application of Mohs micrographic surgery (MMS) in the pediatric population.

OBJECTIVE

We sought to summarize the clinical characteristics of children undergoing MMS, identify challenges that limit the use of MMS in this population, and examine how these challenges can be overcome.

METHODS

A systematic review of PubMed and EMBASE, from inception of databases to November 2, 2019, identified all cases of pediatric skin lesions treated with MMS.

RESULTS

A total of 111 patients were included. The median patient age was 11 years (range 6 weeks to 17 years). The most commonly treated tumor was dermatofibrosarcoma protuberans (n = 62), followed by basal cell carcinoma (n = 30). The most common location was the head and neck (n = 34), followed by the trunk (n = 28) and the extremities (n = 23). The most commonly cited challenges in the application of MMS in children included patient cooperation, concerns for the safety of prolonged general anesthesia, availability of a MMS service in the pediatric setting, and access to a histopathology laboratory experienced in MMS sectioning.

LIMITATIONS

Many articles did not report specific patient characteristics.

CONCLUSION

Multiple obstacles limit the application of MMS in pediatric patients. This review describes practical methods to circumvent these obstacles to facilitate the appropriate use of MMS in children.
