RESEARCH on the biochemistry of melanogenesis can be divided historically into three periods. 1 1. The identification of tryosinase, in 1895, by Bertrand and Bourquelot in certain varieties of mushrooms. 2. The demonstration of "dopa oxidase" in human skin, in 1917, by Bruno Bloch and the elicitation of some of the chemical steps in the conversion ...

AbstractA 24‐year‐old male patient suffering from a large‐coconut‐sized neurofibroma is described. In the tumor, sharply demarcated areas of melanin containing cells were seen. These cells were identified as melanin producers by the premelanosomes seen by electron microscope. Although the coexistence of neurofibroma with another melanin‐producing tumor,
