Electron microscopic identification of aberrant melanosomes using a combined dopa/Warthin-Starry technique.

A method combining the DOPA and Warthin-Starry techniques is described in order to positively establish the nature of pleomorphic granules observed in the cytoplasm of cells of putative amelanotic melanoma. The technique identifies these granules as aberrant melanosomes by discretely depositing electron dense silver on suitably prepared sections of DOPA-treated tissue blocks.

Membrane-bound structures at the interface between tumour and dermis in basal cell carcinoma. An ultrastructural study.

During an ultrastructural study of the interface area between tumour and dermis in 23 basal cell carcinoma (BCC), membrane-bound structures were noted in the dermis adjacent to the basal lamina in 12 tumours (52 per cent), but none of the controls. Serial sectioning demonstrated cytoplasmic connections between these structures and tumour cells. Their formation and interaction with adjacent stromal cells is discussed.
