Melanotic Cancer of Forehead with Metastases in Lymph Vessels and Glands. (Mr. D.P.D. Wilkie's case.)

"Melanotic Cancer.- Under this head are included all new growths which contain an excess of melanin pigment. Many of these were formerly described as melanotic sarcoma. They nearly always originate in a pigmented mole which has been subjected to irritation. The primary growth may remain so small that its presence is not even suspected, or it may increase in size, ulcerate, and fungate. The amount of pigment varies: when small in amount the growth is brown, when abundant it is deep black. The most remarkable feature is the rapidity with which the disease becomes disseminated along the lymphatics, the first evidence of anatomical group of glands should be remove with the tumour in one continuous piece".
