FIGURE LEGEND.Figure 1. Erythematous subcutaneous nodules and angular purpura on the posterior lower legsFigure 2. Histopathological section of lower limb subcutaneous nodule. The findings demonstrated a mixture of lymphocytes, neutrophils, histiocytes and scatted eosinophils surrounding the small arteries and extending into the fibrous septa and peri-septal lobules of the subcutaneous tissue. The internal elastic lamina of the arteriole was preserved. There were no granulomas, and further stains indicated no mycobacterial or fungal elements. These findings were consistent with PAN.Figure 3. Stellate ulcer with retiform purpura. The incisional biopsy demonstrates a prominent lymphohistiocytic infiltrate of small to medium sized vessels in the deep dermis and subcutis. A moderate lymphohistiocytic infiltrate was noted within vessel walls with endarteritis obliterans, degenerate vessel walls and fibrin thrombi with karyorrhexis in the affected lumen.
