BACKGROUND
Wide local excision (WLE) with 2 to 5 cm margins has been conventionally used for the treatment of superficial leiomyosarcoma (LMS). Because margin control is the strongest predictor of clinical recurrence, many dermatologic surgeons have recently recommended Mohs micrographic surgery (MMS) over wide local excision (WLE) as the primary treatment modality.
OBJECTIVE
To determine the aggregate rate of local recurrence after treatment of superficial LMS with MMS among the few reports in the literature.
METHODS
A systematic literature search using the PubMed/MEDLINE database and the Cochrane Library was performed from inception to June 2017. One case report from our institution was included.
RESULTS
A meta‐analysis of 14 reports of 48 cases of superficial LMS treated with MMS showed a mean recurrence rate of 2.08% to 6.25% with a mean follow‐up period of 1570.9 days, compared to reported recurrence rates of 30% to 50% for WLE. Among these cases there were no reports of distant metastases.
CONCLUSION
Treatment of superficial leiomyosarcoma with MMS shows markedly lower rates of recurrence compared to reported rates of recurrence after WLE. Further prospective trials with larger sample sizes are needed to compare both modalities.
This survey highlights a promising state of pediatric dermatology training among current graduating dermatology residents. The majority of current graduating dermatology residents are satisfied with their pediatric dermatology education, feel confident treating pediatric patients, and plan to see pediatric patients in clinical practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
