Extramedullary plasmacytoma is a rare form of plasma cell tumor occurring in a wide variety of organs and tissues. Most tumors occur in the head and neck, involving the nasal cavity, paranasal sinuses, and upper airway. Tl-201 and Ga-67 scan findings in a patient with extramedullary plasmacytoma in the right side of the chest wall are presented. Only a few publications have described Tl-201 or Ga-67 uptake in extramedullary plasmacytoma. This is the first report of both Tl-201 and Ga-67 uptake in an extramedullary (or intramedullary) plasmacytoma.
