Inverted follicular keratosis. A report of two recurrent cases

Few cases of recurrent inverted follicular keratosis (IFK) have been reported in the literature, none with histopathologic confirmation. The authors report two cases of IFK that recurred within weeks of primary excision. Histologic confirmation was obtained on all four specimens. By establishing the benign nature of the recurrent lesions, unnecessary, possibly drastic surgery was avoided.
