RESUMEN
La paraqueratosis granular es una dermatosis de probable etiología reaccional descripta en la última década. Se presenta como pápulas hiperqueratósicas y eritematosas que confluyen formando placas de aspecto reticulado. Predomina en mujeres de entre 50 y 60 años, en zona de pliegues, particularmente axilares. Comunicamos un caso de paraqueratosis granular axilar, el primero dentro de la literatura médica argentina, y revisamos la bibliografía sobre el tema.
