Solitary intracerebral plasmacytoma.

Solitary extramedullary plasmacytomas are rare. Most of them are seen in the nasopharynx, upper respiratory tract, lamina propria of gastro-intestinal tract, lymph nodes, testicles and other soft tissues. So far only 20 such cases are reported in the literature. Here they arise from the dura, or from the periadventitial cells of intracranial vessels. Intracerebral plasmacytomas (ICPC) are extremely rare. Till 1982, Hensen and Urich could trace only 10 occurrences. Here the 11th case, probably the first Indian case report of the occurrence of a solitary plasmacytoma within the left temporal lobe of a 16 year old boy, is presented.
