A case of congenital folliculosebaceous cystic hamartoma in infant is reported. A 2-year-old infant presented with a gradually growing papule on the right face at birth. Physical examination showed a hemispherical reddish well circumscribed papule, with a diameter of 0.8 cm, and a crusted surface. Histopathological examination showed many enlarged deformed fol- lieulosebaceous cystic structures in the upper dennis, and numerous proliferated sebaceous lobules radiated from the deformed cystic follicular structures. There were clefts between the stroma and the cystic tissue. Moreover, disseminated ectopic adioeytes and deposits of mucoid substance were found in the stroma. Congenital folliculosebaceous cystic hamartoma was diagnosed.
