Abstract:  Sebaceous hyperplasia is a common benign proliferation of the sebaceous gland. It commonly presents in middle-aged people as soft, yellow papules with central umbilication on the face, particularly on the forehead. We report a newborn with striking unilateral sebaceous hyperplasia and suggest that this may represent a unique sebaceous hamartoma rather than “premature sebaceous hyperplasia.”
