Unique presentation of a malignant melanoma in a capillary malformation: A case report

Vascular lesions can be subdivided into haemangiomas and vascular malformations. This benign tumour very rarely coexists or transforms into malignancy. In this case report, we present a disseminated malignant melanoma in a capillary malformation. The tumour grew rapidly over a period of 6 months. Changes in vascular lesions should always be investigated thoroughly, as these changes could represent a malignant transformation, metastases or a coexisting tumour – even a malignant melanoma.
