ELECTRON MICROSCOPY OF MELANIN SYNTHESIS IN INTRADERMAL NEVUS CELLS

[摘要] The above findings represent the process of melanization in various developmental stages of an enzymically active cytoplasmic organelle, which is not phagocytized but rather formed within intradermal nevus cells and possesses the essential properties of the described melanosome. This may suggest a melanocytic origin for these intradermal nevus cells rather than a neural origin.
