RESUMO
La paraqueratosis pustulosa es una entidad poco descrita en la literatura y se define como un proceso inflamatorio cutáneo, ungueal y periungueal en el área distal de un dedo habitualmente pulgar o índice, frecuentemente en la infancia. Su evolución suele ser benigna y la respuesta a emolientes tópicos es favorable. A continuación, se presenta un caso de esta enfermedad con el objetivo de resaltar su consideración en patologías ungueales pediátricas.

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.

A 27-year-old female presented with pruritic keratotic papules over the left side of the face since one month. The lesions developed a few days after working in a hot humid environment and were preceded by severe uncontrollable pruritus for which she had repeatedly wiped the area with handkerchiefs and towels. A biopsy from one of the keratotic papules revealed granular parakeratosis with a markedly thick stratum corneum that had parakeratosis and also housed keratohyaline granules. Similar changes were seen in keratotic plugs of dilated follicular infundibula.
