A 55 year old female presented with anemia and dysphagia. There is a feeling of something stuck in the throat. The esophagus can’t be negotiated beyond the crico-pharynx. What is the most probable diagnosis?

The key is B. Plummer Vinson syndrome. [The picture fits two D/D. 1. Plummer Vinson syndrome 2. Oesophagial carcinoma. Lower oesophagial stricture is more common for Ca. So presenting case is likely a case of Plummer Vinson syndrome. It can be differentiated by the type of anemia. If it is IDA diagnosis is Plummer Vinson syndrome].
