DefinitionThis section has been translated automatically.
Asymptomatic, self-limited, trauma-induced bleeding into the skin (horny layer) in the heel area, which appears as black spots over many weeks. They are differential-diagnostically eminently important for the differentiation of a malignant melanoma. Often such bleedings also occur in other mechanically strained regions of the feet (e.g. blakc toes or toe edges in football players).

DiagnosisThis section has been translated automatically.
Reflected light microscopically, a bizarre, splatter-like boundary and remaining red tones indicate a hematoma. If there is further uncertainty regarding the diagnosis, the horny layer can be removed horizontally in layers with a sharp scalpel. Bleeding can usually be completely eliminated in this way. If necessary, the removed material can be processed histologically (detection of blood pigment).

TherapyThis section has been translated automatically.
First of all, reliable diagnosis to exclude a malignant melanoma by reflected light microscopy, if necessary histology. Often a simple securing is achieved by flat cutting of the str. corneum with a scalpel. If necessary, a melanoma can be excluded from the horn material with the Fontana-Masson staining by iron detection.
