title: Angiocentric T cell lymphoma masquerading as cutaneous vasculitis.
abstract: Angiocentric T cell lymphoma may present with cutaneous inflammatory lesions masquerading as cutaneous vasculitis both clinically and pathologically. We describe a case of angiocentric T cell lymphoma. Although initial biopsies in this patient resembled polyarteritis nodosa, subsequent biopsies exhibited more characteristic changes and immunohistochemical stains confirmed the diagnosis of large cell angiocentric cutaneous T cell lymphoma. It is important to differentiate these diseases as treatment and prognostic implications are very different.
