A primer of Mohs micrographic surgery: uncommon indications

Mohs micrographic surgery has been used for the treatment of tumors other than basal and squamous cell carcinomas. Parameters to be considered when deciding on a treatment include location, size, growth pattern, and recurrence rates. It is important to consider that sometimes the high-risk nature of the tumor is more significant than the need for tissue sparing. Modifications to the Mohs micrographic surgery technique may be used to ensure diagnostic accuracy and confirm complete removal of the lesion (e.g., immunohistochemical staining and paraffin-embedded sections).
