title: Scrotal angiokeratoma (Fordyce): histopathological and ultrastructural findings.
abstract: Bioptic findings related to four cases of scrotal angiokeratoma-Fordyce, were studied under light and electron microscopy. A particular heterogeneity of the structural and ultrastructural patterns typical of this lesion was thus observed. Light microscopy study pointed out, in particular, different degrees of dilation of papillary vessels, whereas ultrastructural study highlighted marked alterations of endothelial cells with structural and quantitative modifications of cytoplasmic organelles.
