Recurrent basal cell carcinoma: a clinicopathological study and evaluation of histomorphological findings in primary and recurrent lesions.

Abstract

BCC recurrences may vary considerably with respect to various tumor- and host- -related factors, and so it is impossible to predict them precisely. Although aggressive histological types and positive excision margins are considered the strongest predictors, we demonstrated that half of the primary cancers had shown an indolent character, and that more than half of them had appeared to be completely resected. We can conclude that all patients that have had BCCs removed should be re-examined regularly even after microscopically adequate excisions, or lesions with an indolent histomorphology. Careful monitoring must be undertaken for at least 3 years; however, the most appropriate course is a lifetime of regular follow-up.
