History of left humerus pathological fracture.
MRI and CT of left arm: Expansile osteolytic lesion of the proximal humeral shaft measuring 5.5 cm in length.
Left humerus true cut biopsy: cores of bone and soft tissue exhibit infiltration by sheet of plasma cells with attached bony tissue and fibromuscular tissue noticed. Features consistent with plasma cell neoplasm.

Comment / Findings
- Cellularity: Mild hyper-cellular Bone marrow (Although partially diluted sample)
- Differential Cell Count: Promyelocytes: 4% - Myelocytes: 9% - Metamyelocytes: 11.5% - Band neutrophils: 9.5% - Segmented Neutrophils: 10.5% - Eosinophils: 2% - Basophils: 0.5% - Monocytes: 1.5% --- Lymphocytes: 6% --- Plasma cells: 12.5% --- Erytheroid cells (Normoblasts) : 29%
- Plasma cells: are Increased. There is plasma cells dysplastic features ; immature forms , pleomorphism, mitotic features, nuclear lobulation, binucleation and multinuceation. Mott cells are seen (multiple pale bluish-white, grape-like cytoplasmic accumulations; contain condensed or crystallized cytoplasmic Ig )
- Comment: A case of plasma cell neoplasm mostly plasma cell myeloma to be confirmed by bone marrow trephine biopsy iimmunohistochemistry, immunophenotyping, serum protien electrophoresis and bone scan. Other plasma cell disorders are differential diagnosis.
