Solitary extramedullary plasmacytomas are rare tumors, reported to occur most commonly in the upper respiratory passages, but which also are rarely seen in the middle and lower gastrointestinal system. This report documents the first primary plasmacytoma of the esophagus. A 67-year-old Caucasian man complained of dysphagia and weight loss. Preoperative diagnosis, based on functional inquiry, radiology, and biopsy, was undifferentiated carcinoma involving the lower third of esophagus. The patient was treated by esophagogastrectomy. The pathology specimen revealed the typical histology of plasmacytoma. The extramedullary nature of the tumor was established postoperatively on the basis of the following criteria: 1) Absence of Bence-Jones proteinurea; 2) normal serum electrophoresis; 3) normal bone marrow biopsy; and 4) absence of distant metastases on liver scan and bone survey.

Solitary plasmacytoma involving the larynx is very rare. To the best of our knowledge, there are only 73 cases reported in the world literature. The clinical picture was chronic cough, hoarseness and discrete dysphagia. Complete work-up to rule out systemic evidence of plasmacytoma is necessary. Microscopically, solitary plasmacytoma must also be distinguished from plasma cell granuloma.

Solitary extramedullary plasmacytomas are uncommon neoplasms. They occur most frequently in the upper aerodigestive tract and account for 4% of the nonepithelial tumors in this site. The evolution of a plasmacytoma is unsteady and symptoms at presentation have included dystonia, dysphagia, oral pain, cough, and dyspnea on exertion. Plasmacytoma of the upper aerodigestive tract has not been previously reported as a cause of obstructive sleep apnea.

An uncommon manifestation of plasma cell neoplasia occurs outside the bone marrow and is designated "extramedullary plasmacytoma." These are usually encountered in mucosal sites of the head and neck region. The gastrointestinal tract may be secondarily involved in multiple myeloma or be the site of primary extramedullary plasmacytomas (PEMPs). The esophagus is the least common site of gastrointestinal PEMP. A 58-year-old man presented with dysphagia for solids over a period of 2 months. Otherwise, he was well and systemic examination did not reveal anything of note. After a nondiagnostic biopsy, the patient was subjected to esophago-gastrectomy. Gross examination of the esophagus revealed a large polypoid tumor. Histologically, it was composed of mature plasma cells, plasmablasts (some of which appeared anaplastic), and a minor admixture of lymphoid cells. Focally, the infiltrate permeated the squamous epithelium simulating lymphoepithelial lesions. The neoplastic cells were positive for epithelial membrane antigen, CD79a, IgG, and kappa, while the lymphoid cells were predominantly B cells. The patient did not have a monoclonal gammopathy. Skeletal x-rays and bone trephine examination were both normal. PEMP is biologically and prognostically different to other plasma cell neoplasms. Although rare, esophageal PEMP should be considered in the differential diagnosis of so-called undifferentiated malignant tumors of the esophagus.

Plasmacytoma is a discrete solitary mass of neoplastic monoclonal plasma cells in either bone marrow or soft tissue sites. Extramedullary plasmacytoma or multiple myeloma of the larynx is extremely a rare condition. We report a 77-year-old male patient diagnosed with multiple myeloma and presented with dysphagia. The rarity of the disease incidence and difficulty of the diagnosis of this disease is discussed. We present this case to increase the awareness of the Otolaryngologists of this rare disease to expedite its diagnosis and management.

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.
