title: Erythrophagocytosis by segmented neutrophils in paroxysmal cold hemoglobinuria.
abstract: The authors report a case of paroxysmal cold hemoglobinuria (PCH) with pronounced erythrophagocytosis by segmented neutrophils. This type of erythrophagocytosis, though well-documented in vitro, is a rare phenomenon in vivo. A review of the literature shows an association between PCH and erythrophagocytosis by segmented neutrophils that the authors suggest may have diagnostic value.
