Presentación atípica de la poliangeítis microscópica con compomiso renal, pulmonar, dermatológico y del sistema nervioso central

Atypical presentation of microscopic polyangiitis with renal, pulmonary, dermatological and central nervous system involvement

La poliangeítis microscópica (PAM) es una vasculitis autoinmune caracterizada por la inflamación de los vasos sanguíneos de pequeño calibre y la presencia de anticuerpos anticitoplasma de neutrófilos (ANCA). Clínicamente se caracteriza por presentar glomerulonefritis y capilaritis pulmonar aunque la afectación de la piel, los nervios y el tracto gastrointestinal no es infrecuente. Presentamos el caso de un paciente de 17 años con manifestaciones atípicas dadas por glomerulonefritis pauci-inmune, hemorragia pulmonar, vasculitis leucocitoclásica cutánea y hemorragia cerebral. Además revisamos las características histológicas y radiológicas.
