title: Basal-cell carcinoma complicating a port-wine stain.
abstract: A rare radio-resistant basal-cell carcinoma is described which presented as a recently enlarged non-ulcerated nodule on a port-wine stain. The literature on basal-cell carcinoma occurring on a port-wine stain is reviewed, and the aetiological significance of thorium-X, sun-exposure and vascular changes in the development of malignancy on this type of haemangioma is discussed.
