Inverted follicular keratosis.
Attention is drawn to a benign skin tumour which has escaped recognition in the British lieterautre. Inverted folliculr keratosis can be mistaken clinically for basal cell carcinoma and a variety of benign skin lesions. Pathologically it is easliy confused with squamous carcinoma, a serious error because this lesion occurs dominantly on the face. The lesion is thought to arise from the infundibulum of hair follicte.
