Solitary plasmacytoma of the skull is very rare and only 35 cases have been
reported in the English literature. It remains controversial whether
solitary plasmacytoma of the skull is essentially identical with solitary
plasmacytoma of bone or not. Solitary plasmacytoma of bone including
solitary plasmacytoma of the skull is characterized by a radiologically
solitary bone lesion, neoplastic plasma cells in the biopsy specimen, fewer
than 5% plasma cells in bone marrow, less than 2.0 g/dl monoclonal protein
in the serum when present and negative urine test for Bence Jones protein
(monoclonal light chain). Solitary plasmacytoma of bone tends to
disseminate or progress to multiple myeloma even as long as 7-23 years
after presentation. We report the first case of solitary plasmacytoma of
the skull in which both beta2-microglobulin for detection of early renal
disturbance and neoplastic plasma cell labeling index for detection of DNA
synthesis were examined in order to predict the clinical course of solitary
plasmacytoma of the skull.
