| melanophore | Cell type found in skin of lower vertebrates (amphibian skin, fish scales) that contains granules of the black pigment melanin. The granules can be rapidly redeployed between a dispersed state (which darkens the skin) and concentration at the centre (which lightens it).

| melanophore-expanding principle | A polypeptide hormone secreted by the intermediate lobe of the hypophysis in humans (in neurohypophysis in certain other species) which causes dispersion of melanin by melanophores, resulting in darkening of the skin, presumably by promoting melanin synthesis; this effect is readily demonstated in some lower vertebrates, such as frogs and fish; alpha-melanotropin is an N-acetylated peptide with 13 amino acids; beta-melanotropin has 22 amino acids. Synonym: intermedin, melanocyte-stimulating hormone, melanophore-expanding principle. (05 Mar 2000) |

| melanosis corii degenerativa | A congenital abnormality in which pigment is deposited in whorls and streaks; vesicles occasionally occur, and it may be associated with cardiac or neurologic disorders. Compare: incontinentia pigmenti, incontinentia pigmenti achromians. (05 Mar 2000) |

| melanoma |
a cancerous (malignant) tumor that begins in the cells that produce the skin coloring (melanocytes). Melanoma is almost always curable in its early stages. However, it is likely to spread, and once it has spread to other parts of the body the chances for a cure are much less.
