Erythremic crisis

Erythrematic crisis (syn. erythremia, erythraean disease, paroxysmal nocturnal hemoglobinuria or benzine typhuginous purpura) is a rare myeloproliferative disease characterized by the development of bone marrow aplasia and severe hemolysis with the release of hemosiderin in the urine and feces. Due to the staining of the latter with red blood cells, they are called “bath bottles”. The disease was previously called homozygous band erythremia. This form of the disease is characterized by an increased content of hemomelatine, a pigment saturated with hemosiderin, which colors the urinary sediment brownish-black. Also noted
