Reflected light microscopic phenomenon in which the architectonics of the lesion is predominantly characterized by differently shaped vessel figures with caliber fluctuations and bulges.

General information
This section has been translated automatically.

Reflected light microscopy: Aneurysmatically dilated capillaries with pronounced caliber fluctuations and isolated microscopic bleeding runs through the entire lesion. As an indication of the presence of a pigment cell tumor, often only discrete brownish-cloudy areas or a light brown background pigmentation are found. Discrete slate-grey pigment cell agglomerates are rare. Polymorphic vessel figures remind in their shape of Greek lower case letters (minuscule).
