• Dark blue-black pigmentation has persisted in areas of previous acne scarring in a young woman. By histologic and electron microscopic examination, the pigment is demonstrated to represent hemosiderin. Much of the hemosiderin is lying free within macrophages, not bound by lysosomal membranes that normally would protect the cell from this toxic material.
