There are a few instances in the literature of the coexistence of these two abnormal pigments in the same patient.1 Although it must occur commonly after treatment with certain drugs,2 no well documented reports were found of the spontaneous occurrence of both hemolytic anemia and abnormal intracellular pigments.
