Vitamin B 12 deficiency is a rare cause of fever of unknown origin. We describe here a case report of a 24-year-old pure vegetarian male who presented to us as pyrexia of unknown origin (PUO). After meticulous evaluation and exclusion of infective, inflammatory and endocrine causes, the cause of illness was attributed to Vitamin B 12 deficiency. There was swift and dramatic recovery with parenteral Vitamin B 12 supplementation. Vitamin B 12 deficiency should be borne in mind, whereas evaluating a febrile patient particularly with pancytopenia and hyper pigmentation as it is one of the rarer, but easily correctable and reversible causes of PUO.
