Basal-cell carcinoma of the vermilion mucosa and skin of the lip.

In a series of 652 basal-cell carcinomas, twelve were on the upper lip and five were on the lower lip. Three cases of basal-cell carcinoma located on the vermilion mucosa, with only slight involvement of the contiguous skin at the mucocutaneous junction, are reported. Two were on the lower lip and one on the upper lip. The patients were 74, 81, and 81 years of age. All underwent adequate wide local excision. None of the lesions recurred clinically or metastasized over periods of 41 to 80 months.
