Abstract

We present the case of a 16-year-old boy with hemolytic anemia with investigations showing pancytopenia, which turned out to be due to B12 deficiency. Whenever we see a teenager presenting with pancytopenia the common causes, we think of are hemaltologic malignancies, Drug induced cytopenias, hypersplenism etc. Anemia as a presentation is common in B12 deficiency, yet it is presenting with jaundice is a very uncommon and easily overlooked presentation, same is the case of B12 presenting as pancytopenia which is a well described entity yet omitted initially owing to its uncommonality in this modern developed world.
