Pigmented Basal-cell carcinoma of the upper lip: A report of a case and review of the literature.

Basal-cell carcinoma (BCC) rarely occurs on the lip. We herein report a case of an 89-year-old male, who presented with a blackish nodule on the vermilion border and the outer mucosa of the right side of the upper lip. A diagnosis of pigmented BCC was made by histopathological examination. The patient was successfully treated by Abbe flap with excellent esthetic and functional results. We have reviewed 64 cases of lip BCCs previously reported. There was no gender predominance, and the upper lip was involved 1.5 times higher than the lower lip. There was no lymph node metastasis, and thus, lip BCC had a good prognosis. [ABSTRACT FROM AUTHOR]
