A 56 year old man was brought to emergency by his wife, who reported that he was playing catch with his son when he suddenly experienced acute pain in his right arm, accompanied almost immediately by swelling and loss of mobility.

Images hosted on PathOut server: Bone marrow biopsy has blast-like cells.

Chronic antigen stimulation, exposure to radiation or toxins results in increased risk but most patients do not have these associated df.

CT of skull with multiple maladle bone lesions. Accessed December 31st, Board review answer 3. In situ hybridization for kappa left and lambda right.

Interactions between bone marrow stroma and plasma cells directly influences disease with a potential key role of IL6 to support survival and expansion of myeloma cells IL6 with other cytokines promotes osteoclastic activity and lytic bone lesions. Peripheral blood shows plasma cells right: Large tubular casts blocking the lumen. Hypercellular marrow with plasmacytoid cells. Rouleaux formation in the peripheral blood.
