ANAPLASTIC MYELOMA

Anaplastic myeloma (AM) represents a rare variety of multiple myeloma (MM) with poor prognosis. One case with special interest is reported, which presented with manifestations due to the extramedullary localiza tion and arose in the absence of an initial diagnosis, of MM. In addit ion, differential diagnosis was based on morphological and immunocytoc hemical findings while treatment with radio-chemotherapy had no effect on the extramedullary sites.
