Solitary tracheal plasmacytoma: computed tomography and pathological findings

Extramedullary plasmacytomas most frequently occur in the head and the neck, although intrathoracic cases have occasionally been described. Solitary tracheal plasmacytomas are exceedingly rare. The authors describe the computed tomography and pathological appearance of a solitary tracheal plasmacytoma and briefly discuss the treatment and implications of such a lesion.
