Understanding Dermatofibrosarcoma Protuberans: A Guide for Patients

Dermatofibrosarcoma protuberans (DFSP) is a rare skin cancer that begins in the dermis and can affect the skin, fat, and occasionally deeper tissues. It is slow-growing and rarely spreads, but it often returns if not treated fully. This resource explains how DFSP may appear as rough patches, bumps, or discolored areas on the skin, and why it can be mistaken for benign conditions in its early stages. Diagnosis typically involves a skin biopsy and sometimes imaging, with Mohs surgery or wide local excision being the main treatments. Additional options such as radiation therapy or targeted medications like imatinib may be considered in certain cases. Regular follow-up skin checks and exams are essential after treatment to monitor for recurrence and support long-term health.
