Primary extramedullary esophageal plasmacytoma - a case report.

Extramedullary plasmacytomas are very uncommon tumors, may occur commonly in the upper respiratory passages. These are rarely seen in the middle and lower gastrointestinal system and exceptional to originate in the esophagus. We present a novel case of a 65-year old man who presented with dysphagia and weight loss. After taking detailed clinical history and physical examination endoscopy was performed that showed an ulcero-proliferative lesion involving the lower third of esophagus. Histopathological examination revealed sheets of malignant plasma cells, some with prominent nucleoli. Immuno-histochemistry could not be done due to unavailability. A bone marrow biopsy was performed which was negative for involvement. This is a rare case of esophageal plasmacytoma diagnosed on endoscopy in a patient presenting with dysphagia.
