1953 Science 5 June 640/1 Investigators in biology and medicine at the present time are using different terms for the same cell. For example, the term melanophore which has long been used by biologists refers to certain dendritic-shaped cells in the skin of fish, amphibians and reptiles which have ‘contractile’ properties. The melanin contained in the melanophores may, in response to certain stimuli, disperse into the dendrites or concentrate in the perikaryon, thus accounting for the color change. In human cytology and pathology the term melanophore is a macrophage.

The term ‘melanin granule’ could be reserved for the mature, fully melanized particle which has lost its tyrosinase activity and is no longer confined to the cytoplasm of the melanocyte.
