Figure 3: Histopathology showing (a) dense diffuse infiltrates of mast cells in the upper third of the dermis (H and E, 50X), insert (H and E, 100X); (b) telangiectasia with mild perivascular infiltrates of lymphocytes and scattered mast cells in the superficial dermis, basal layer hyperpigmentation (H and E, 100X); (c) proliferated blood vessels with moderate aggregates of mast cells admixed with occasional lymphocytes and histiocytes (H and E, 100X); (d) intraepidermal bulla with diffuse and perivascular aggregates of mast cells in the dermis (H and E, 50X) (e) Mast cells highlighted using toluidine blue stain (200X); (f) CD117 positive mast cells (immunoperoxidase stain, 100X)
