Pathology of Multiple Myeloma Pathology Made Simple
The first round of anti-CD20 depletion was performed at 1.5 years after vaccination and when tetanus-specific memory B cell frequencies were determined at 1.7 years (2.5 months after depletion.

Plasma cells vary in size from 14 to 20 micrometers. They are round-to-ovoid cells containing abundant deep blue cytoplasm with a pale perinuclear area corresponding to the Golgi apparatus. They have a round, eccentrically placed nucleus with coarse chromatin arranged in a clock face (art wheel) pattern. Most plasma cells are uninucleate; few.

However, the nuclei of these plasma cells are eccentric with a morphology typical of plasma cells (coarse chromatin, arranged in a clock face pattern). Immunophenotyping of these cases is very helpful as plasma cells in this variant are positive for CD138, in contrast to histiocytes in crystal storing histiocytosis which are positive for.

Mott cells are plasma cells that have spherical inclusions packed in their cytoplasm. The term 'Mott cell' is named after a surgeon, F. W. Mott, who identified these cells in the brains of monkeys with trypanosomiasis (1901). He termed it morular cell (from the Latin morus, mulberry) and recognized these cells to be plasma cells and.

Plasma cells: Clock face nuclei, paranuclear clearing. Characteristic of chronic inflammation near mucous membranes and often seen around invasive tumours. Lymphocytes and histiocytes: The predominant cell type in most inflammatory skin diseases. Histiocytes are macrophages, and may be seen to have engulfed debris.
Pathology Outlines Plasmacytoma
An accumulation of plasma cells demonstrates two diagnostic features that help identify plasma cells. Heterochromatin frequently clumps around the periphery of the nucleus, forming a "clock face" appearance. Additionally, a pale-staining region in the cytoplasm adjacent to the nucleus indicates the position of the large Golgi apparatus.

The plasma cell clock-face or cart-wheel nuclear pattern as seen in 2D sections/projections from almost any angle can be explained by the multiradial arrangement of peripherally placed clump units.
Multiple Myeloma Stepwards
The nucleus of the plasma cell is spherical and usually eccentrically positioned. It contains large clumps of peripheral heterochromatin interspersed with clear areas of euchromatin, giving it a characteristic cartwheel or an analog clock face appearance.

Multiple Myeloma is neoplastic proliferation of plasma cells that commonly results in multiple skeletal lesions, hypercalcemia, renal insufficiency, and anemia. Patients typically present at ages > 40 with localized bone pain or a pathologic fracture. Diagnosis is made with a bone marrow biopsy showing monoclonal plasma cells โฅ10%.

Bone Marrow nonneoplastic Plasma cells
Plasma cells and osteoblasts are sometimes confused on bone marrow aspirate smear morphology. Although both have eccentrically placed nuclei and can feature a pale paranuclear Golgi zone, note the clumped chromatin pattern of the plasma cell (sometimes described as a 'spoke wheel' or 'clock face'). Frequently the nuclei of osteoblasts.

Plasma cells are 14 to 20 microns in diameter and are characterized by a strongly basophilic cytoplasm. Electron microscopy reveals an eccentrically-located nucleus that has a well-developed nucleolus and variable amounts of condensed chromatin. Chromatin associated with the nuclear membrane gives the nuclei the appearance of a clock-face or.
