An Extraosseous Plasmacytoma of the Nasopharynx
UNLABELLED A 75-year-old long-term male smoker and poorly controlled hypertensive presented with a 3-month history of intermittent epistaxis refractory to cauterisation with silver nitrate. Nasopharyngeal examination revealed a mass in the post nasal space. An urgent endoscopic biopsy confirmed an extraosseous plasmacytoma. Post operative radiotherapy was scheduled. No evidence of recurrence of...
متن کاملExtraosseous chordoma of the nasopharynx.
BACKGROUND AND PURPOSE Chordoma is a relatively rare tumor of the skull base and sacrum thought to originate from embryonic remnants of the notochord. Chordomas arising from the skull base/clivus are typically locally aggressive with lytic bone destruction. When chordomas occur in an extraosseous location, they may mimic other lesions of the nasopharynx. We present 5 cases of primarily extraoss...
متن کاملSolitary extraosseous plasmacytoma
Plasma cell neoplasms are characterized by a neoplastic plasma cell lineage which produces a monoclonal immunoglobulin. These neoplasms can present as a single lesion (solitary plasmacytoma) or as multiple lesions (multiple myeloma). Solitary plasmacytomas most frequently occur in bone (plasmacytomas of bone), but can also be found outside bone in soft tissues (extramedullary plasmacytomas).
متن کاملIL-6 transgenic mouse model for extraosseous plasmacytoma.
Plasma cell neoplasms in humans comprise plasma cell myeloma, otherwise known as multiple myeloma, Ig deposition and heavy chain diseases, and plasmacytoma (PCT). A subset of PCT, designated extramedullary PCT, is distinguished from multiple myeloma and solitary PCT of bone by its distribution among various tissue sites but not the bone marrow. Extramedullary (extraosseus) PCT are rare spontane...
متن کاملUnusual coexistence of extramedullary plasmacytoma and nasopharyngeal carcinoma in nasopharynx
Nasopharyngeal carcinoma (NPC) is an EBV-associated malignant tumor of nasopharynx. As extremely rare condition, the second primary cancer of nasopharynx can occur in NPC patients synchronously or subsequently. Extramedullary plasmacytoma (EMP) is a rare tumor and commonly originates in the head and neck region. However, there is no report to describe a collision tumor of NPC and EMP occurring ...
