A – cabot ring, B – Howell-Jolly Body What are Cabot’s rings? - They are delicate threadlike inclusions in the red blood cells in the peripheral blood of some patients with severe/megaloblastic anaemia. - They may appear as rings, figures-of-eight, or twisted. They are blue-staining and their origin is unknown. Contrary to Cabot’s belief, these structures have nothing to do with the nucleus or the nucleus’ membrane. #Clinical #Pathology #Microscopy #BloodSmear #CabotRings
