Fibrous Tissue Abnormalities – Dermatofibrosarcoma Protuberans

Dermatofibromsarcoma Protuberans (DFSP) is a malignant fibrous tissue abnormality that I rarely encounter in both my The Woodlands dermatology and Conroe dermatology offices.  Clinically, DFSP resembles a large flesh colored/reddish brown protuberant nodule that may have an appearance of a keloid.  They are most often found on the trunk and proximal extremities.  DFSPs become larger over time and can become very locally invasive and they do have the ability to metastasize to other organs such as the lungs.  Mohs sugery is the treatment of choice.
