Therapy

Melanoacanthoma is usually a histological diagnosis by chance. Since it was removed in toto either under the suspected diagnosis "malignant melanoma" or "pigmented verruca seborrhoica", further surgical measures of this benign tumor are not necessary. If necessary, the residual tumor can be cured in LA.

Progression/forecast
This section has been translated automatically.

Benign.
