Reflected light microscopic phenomenon as a consequence of reactive compact hyperkeratosis of the stratum corneum, combined with epidermal hypergranulosis.
General informationThis section has been translated automatically.
Incident light microscopy: An opaque, milky glass-like veil is formed in the incident light microscopic projection plane. A bluish shimmer is produced by light reflection in the area of underlying melanophagus agglomerates (always without transepidermal pigment exudation) or the melanocyte nests (Tydall phenomenon). Accompanying neovascularizations convey reddish color effects.
OccurrenceThis section has been translated automatically.
Within the group of pigment cell tumors the characteristic of opaque appearing veil-like structures is found with a specificity of more than 95% in malignant melanomas (sensitivity about 30%). This phenomenon rarely occurs in Spitz nevi, blue nevi or recurrent nevi.
