Normal Sebaceous Gland

Normal Sebaceous Gland •A normal sebaceous gland under high power. •Towards the periphery of this single acinus of a sebaceous gland is a single layer of cuboidal cells that are somewhat deeper staining. •Towards the center are large cells which are pale staining cytoplasm and a central pyknotic nucleus. •At the very center is a dark staining structure that represents the duct of this gland. •The central, light-staining cells are normally shed as such into the hair shaft and form the oily secretion that coats the hair as well as the overlying skin.
