Large pseudoencapsulated subcutaneous angiomyxoma: Surgical management

Superficial angiomyxoma is a rare benign skin tumor of mesenchymal origin composed of a myxoid matrix, thin-walled blood vessels, and sparse small spindle cells. This tumor is reported to have a high local recurrence rate when excised, possibly because muscle and soft tissue infiltration can occur. Thus, the term superficial can be misleading. In one published series, the local recurrence rate was 36%1 and in another 38%.2 However, all reported series are pathologic studies in which details of surgical excisions are scant.
