All of the following conditions are associated with palpable purpura, EXCEPT:: (A) Giant cell aeritis, (B) Henoch Schonlein Purpura, (C) Wegner granulomatosis, (D) Polyaeritis nodosa
Answer is A. Differential diagnosis of palpable purpura includes Henoch-Schonlein purpura (HSP), cryoglobulinemia or cryofibrinogenemia, polyaeritis nodosa (PAN), Wegener's granulomatosis, infections, and collagen vascular disorders. Giant cell aeritis being a large vessel vasculitis does not cause any purpura.
