title: Cutaneous North American blastomycosis and black dots.
abstract: The presence of black dots may be an aid in the diagnosis of blastomycosis of the skin. Degeneration of papillary blood vessels leads to extravasation of red blood cells. The cells are found in the dermis and between epidermal cells.
