Human melanoma associated with 24 nm particles.
Electron microscopic examination of epidermal tissue adjacent to a skin melanoma in a White male showed the presence of 24 nm particles within a cytoplasmic vacuole. No aetiological significance can be attributed to this single finding but it is possible that examination of tissues proximal to these neoplasms may be of value. As these tumors induce strong antibody responses in allogeneic and xenogeneic hosts it has often been suggested that they may be viral in origin.
