Diagnosis

Tests and procedures used to diagnose dermatofibrosarcoma protuberans include:

• Skin examination. Your doctor will carefully inspect your skin to understand your condition.
• Skin biopsy. Your doctor will remove a small amount of tissue for testing. Specialized laboratory tests can determine if cancer cells are present.
• Imaging tests. In certain cases, your doctor may recommend imaging tests, such as an MRI, to better understand the extent of your cancer and to help with treatment planning.
