Is Tumor of Follicular Infundibulum a Reaction to Dermal Scarring?

Tumor of follicular infundibulum (TFI) is currently believed to be a benign epithelial neoplasm with follicular differentiation. It has been suggested that TFI is associated with dermal scarring, but further investigation is needed to confirm this correlation. To approach this question, a retrospective study was presented, a total of 67 cases (64 lesions) were found in a search covering cases over a 10-year period.
