Basal cell carcinoma arising in a port-wine stain.
BACKGROUND
The occurrence of basal cell carcinoma within a port-wine stain or nevus flammeus is rare. Sixteen cases of basal cell carcinoma which developed in a port-wine stain or nevus flammeus have been reported.


OBJECTIVE
The objective was to demonstrate a rare case of basal cell carcinoma occurring in a port-wine stain successfully treated with Mohs micrographic surgery.


METHODS
This is a case report and literature review.


RESULTS
An 87-year-old man presented with a basal cell carcinoma on the margin of a previously untreated port-wine stain on the left cheek. Histologic examination showed a nodular basal cell carcinoma. The basal cell carcinoma was completely excised with Mohs micrographic surgery and complex linear closure was used to repair the wound in layers. The postoperative course was complicated by a hematoma, which developed 24 hr postoperatively. The hematoma was drained and there was no further bleeding or evidence of recurrence of the tumor after 12 months.


CONCLUSIONS
Basal cell carcinoma should be included in the differential diagnosis of a skin lesion occurring in a port-wine stain.
