title: A solitary plasmacytoma in a dog with progression to a disseminated myeloma.
abstract: Solitary plasmacytomas are rare occurrences in dogs, consequently their potential for malignancy is undetermined. A solitary plasmacytoma was removed from the perianal region of a dog. The dog was clinically normal at that time, but was killed one year later as a result of hind limb stiffness and uremia. At the postmortem examination a disseminated myeloma was found, involving the vertebral column, liver, spleen, bone marrow and visceral lymph nodes.
