Bednar’s tumor is a skin growth, thought to be a rare variation of a form of skin called dermatofibrosarcoma protuberans (see also dermatofibrosarcoma protuberans). Bednar's tumors are characterized by dark color pigmented cells. They are most often benign (non-cancerous) as compared to other dermatofibrosarcoma protuberans (DFSP) which can be cancerous. Bednar's tumors generally appear anywhere from early to middle adulthood. This type of skin tumor most often grows on the shoulders, trunk, and neck areas and appears to grow outward from the surface of the skin. This type of tumor usually does not spread, however, recurrent growths are common even after surgical removal.
Symptoms include lumps in the growth areas, hard skin nodules, red-lumps on the skin, and red-blue skin lumps. Although the risks for this form of cancer are not well understood, it is not thought to be an inherited condition and happens randomly (sporadic) in the population. Studies do show however that Bednar's tumor occur more frequently in the African population but are still very rare. More research is needed to better understand what causes Bednar’s tumor; however, risks for DFSP include a scar that arises after a burn or surgery. Diagnosis includes a biopsy, a sample of cells taken directly from the tumor or discolored region, which is then examined under a microscope. The most effective form of treatment is surgery despite the regrowth risk. It is critical to talk with your physician if are experiencing these symptoms. If you or your family member have been diagnosed with Bednor’s tumor, talk with your doctor and specialist about the most current treatment options.
