Dermatofibrosarcoma protuberans growing around plantar aponeurosis: excision by Mohs micrographic surgery.
BACKGROUND
Dermatofibrosarcoma protuberans (DFSP) is a spindle cell malignancy that has a high local recurrence rate after excision with minimal or no immediate tissue margin assessment. DFSP is exceedingly rare on the palms and soles.


OBJECTIVE
To report a case of a locally aggressive DFSP on the sole excised using Mohs micrographic surgery.


METHODS
Case report and review of the literature.


RESULTS
Mohs micrographic surgery unmasked tumor infiltration that extended around plantar aponeurosis and into underlying plantar muscle fascia.


CONCLUSIONS
Mohs micrographic surgery should be considered the treatment of choice for DFSP, especially in acral locations. This technique allows the surgeon to trace out deep tumor extensions that may wrap around underlying tendon, a finding that may not be appreciated clinically.
