Keloid scarring following skin cancer removal. Close-up of keloid scarring on the neck of a 22-year-old male patient following dissection (removal) of metastatic (spreading) melanoma. Melanomas are the most dangerous form of skin cancer. They are invasive and may spread to other parts of the body (metastasis). If this occurs, the prognosis is poor. If the cancer has not spread, surgical removal may effect a cure. Keloid scars consist of a masses of collagen, a tough fibrous protein, and form as a result of a defective healing process.
