Inverted follicular keratosis is believed to be an inflammatory variant of seborrheic keratosis. This is an acquired lesion, similar to seborrheic keratosis. It commonly is found on the face and sun-exposed areas of elderly patients. Typically, this lesion is located on the upper eyelid. Anatomically, it represents an upside-down or endophytic process within the epithelium of a pilosebaceous follicle. The lesions tend to be single and present as a papule or nodule.
