Figure 2: (a) Lower dermis shows perivascular and interstitial neutrophilic and lymphocytic infiltrate. There is granulomatous infiltrate around the necrotic adipocytes along with neutrophils surrounding and infiltrating the vessel walls (H and E, ×100), (b) higher magnification showing necrotizing granuloma in the subcutaneous tissue with leukocytoclastic vasculitis in the vicinity (H and E, ×200), (c) the epidermis demonstrates hyperkeratosis and parakeratosis. There is dense inflammation throughout the dermis concentrated around the vessels and in the interstitium (H and E, ×40), (d) the deep dermis showing wedge-shaped areas of necrosis with palisading of histiocytes around the necrobiotic foci and dense perivascular and interstitial infiltrate of neutrophils and lymphocytes (H and E, ×200), (e) higher magnification depicting endothelial swelling, neutrophils, and lymphocytes in the perivascular area and walls of the blood vessels and fibrinoid necrosis of the capillaries (H and E, ×400)
