Moritz Kaposi (1837-1902) was a Hungarian physician and dermatologist. Kaposi's main work was Pathologie und Therapie der Hautkrankheiten in Vorlesungen f羹r praktische ?rzte und Studierende (Pathology and Therapy of the Skin Diseases in Lectures for Practical Physicians and Students), published in 1880, which became one of the most significant books in the history of dermatology. Kaposi was the first to study Lichen scrofolosorum and Lupus erythematosus and is credited with advancing the use of pathologic examination in the diagnosis of dermatologic diseases. His name entered into the history of medicine in 1872, when he described for the first time Kaposi's sarcoma, a cancer of the skin, which he had discovered in five elderly male patients and which he initially named "idiopathic multiple pigmented sarcoma". He lived to the age of 64.
