Inverted Follicular Keratosis of the Eyelid Mimicking as Cutaneous Horn

Year: 2025

Type: article

Abstract: Inverted follicular keratosis (IFK) is a rare benign tumour of skin characterized by exo-/ endophytic growth on the follicular infundibulum. Clinical as well as pathological resemblance between IFK and other cutaneous lesions commonly verruca vulgaris, actinic keratosis, seborrheic keratosis, and keratoacanthoma; less commonly between basal and squamous cell carcinoma; and most rarely with malignant melanoma is reported. IFK commonly occurs as a benign, solitary verrucous papule or nodule, predominantly on the skin of the face most often in elderly men. Clinically they are often considered to be viral warts. Rarely they present as 'cutaneous horns'. Herein we present a case of inverted follicular keratosis of upper eyelid mimicking as cutaneous horn. Lesion was completely excised and histopathological examination revealed the diagnosis of IFK.
