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%.
Bone Marrow nonneoplastic Plasma cells
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.

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 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.

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.

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.

Definition / general. Usually less than 1% of marrow cells; rare in infants. Often perivascular and in particle crush specimens. Indeterminate lifespan ranging from days to months. Produces and secretes antibodies. Plasmablast: precursor to plasma cell, produces more antibodies than B cells but less than mature plasma cells.

Clock-Face Chromatin Pattern: Within the nucleus, the chromatin forms clumps or patches, resembling a clock-face arrangement. This pattern is a characteristic feature of plasma cells and distinguishes them from other immune cell types. Localization of Plasma Cells: Plasma cells are found in various anatomical locations within the body, including:
