A 19-year-old male presented with a 6-year history of white papulas on palmoplantar, follicular-like papules on scalp and tempus for more than one year, and a 2-month history of follicular-like papules on neck. There were no similar patients in his family. Dermatological examination revealed whitish and hard palmoplantar hyperkeratosis. The dark brown and greasy follicular papules of sizes between needlepoint and rice distributed symmetrically on scalp, tempus and neck. Histopathological examination of lesions showed hyperkeratosis of epidermis and focal parakeratosis. The formation of rounds and grains-like horus could be seen in some sections. Acanthosis, papillomatosis and acantholysis were also observed. There was lacunae formation at the top of the basal lamina with spines release cells and villi structures. Mononuclear cells infiltrated around blood vessels in the superficial dermis. Based on clinical and histopathological manifestation, a diagnosis of follicular keratosis was made.
