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 ≥10%.

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.

"Clock-face" chromatin pattern. Small dots symmetrically rim the nuclear membrane - like the numbers on a clock. Abundant cytoplasm. Nucleus-to-cytoplasm ratio ~1:2.

Structure Plasma cells with Dutcher and Russell bodies (H&E stain, 100×, oil). Plasma cells are large lymphocytes with abundant cytoplasm and a characteristic appearance on light microscopy.They have basophilic cytoplasm and an eccentric nucleus with heterochromatin in a characteristic cartwheel or clock face arrangement. Their cytoplasm also contains a pale zone that on electron microscopy.

Plasma cells - 1. #00004107. Author: Peter Maslak. Category: Lymphoma: Mature B-cell and Plasma cell Neoplasms > Plasma Cell Neoplasm. Published Date: 11/01/2009. Plasma cells (arrows) have eccentric nuclei characterized by a "clock face" appearance to the chromatin. The cytoplasm may range from basophilic to blue-gray and can contain vacuoles.

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 Stepwards

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.

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.

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.

Lymphocytes and histiocytes: The predominant cell type in most inflammatory skin diseases. Histiocytes are macrophages, and may be seen to have engulfed debris.

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.

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.
