Melanoma arises from melanocytes - cells that make up the pigment. The reason for their malignancy is not certain. The development of melanoma moles (nevi), papilomatoznyh age spots contribute to injury, cautery, cuts, excessive sun exposure, and other annoyances.
The main feature - the strengthening or weakening of the pigment nevus, increasing it in size, ulceration, bleeding, brown, pink corolla or radial strands forming around tumors or stains. Soon comes the dissemination process: first to the neighboring areas of the skin in the form of nodules satellite, then in regional lymph nodes, in later periods gives metastases in the internal organs. Early melanoma ulceration is a poor prognostic sign. Malignant process increases sharply during trauma tumor.
