Definition

Reflected light microscopic phenomenon of immunologically controlled inflammatory processes within melanocytic and epidermal skin lesions. Loosely aggregated melanophages accumulate in the immediate vicinity of skin vessels.
General information
This section has been translated automatically.
- Reflected light microscopy: Grey, grey-blueish, grey-brown or grey-violet, loosely distributed pigment spots (melanophages) accumulate in the area of skin vessels and can accompany them over longer distances. Differently strong and asymmetrically distributed accumulations of melanophages within the dermal papilla indicate malignant processes.
Occurrence
