Vitamin B12 deficiency: report of a childhood case.

Author information

Department of Pediatrics, Bhumipol Adulyadej Hospital, Donmuang, Bangkok, Thailand.


An 11-year-old boy who presented with anemia, premature grey hair, hyperpigmented skin, paresthesia, recurrent aphthous ulcers and epistaxis was eventually proved to be a case of vitamin B12 deficiency. Due to the paucity of this deficiency, the diagnosis may easily be delayed and overlooked resulting in unfavorable consequences. Therapeutic response to vitamin B12 was dramatic in this reported case.
