Chromatin is heavily clumped, and dense masses of chromatin show the typical "spoke wheel" or "clock face" chromatin pattern. Nucleolus is not visible. The cytoplasm is abundant, always basophilic and usually deep blue. A well-defined large and colorless perinuclear hof is present in almost all PC and corresponds to the uncolored Golgi.
Transcriptional Architecture and Chromatin Landscape of the Core
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.

Chromatin landscape and circadian dynamics Spatial and temporal
Abstract In the fully-developed megaloblast of vitamin B 12 or folate deficiency, unique alterations occur in the chromatin adherent to the nuclear membrane. This chromatin is often tenuously connected to or separated from other chromatin, and gives the nucleus a clockface appearance.
Pathology Cases LN review
Chromatin associated with the nuclear membrane gives the nuclei the appearance of a clock-face or cartwheel. The cytoplasm contains a prominent Golgi apparatus and endoplasmic reticulum. The precursors of plasma cells are plasmablasts which migrate to bone marrow after stimulation by cytokines from helper T cells in the germinal centers of.

Pathophysiology refers to changes in bodily processes that result from disease. In the case of multiple myeloma (MM), which is a type of bone marrow cancer, the pathophysiology is complex. It can.
Cold‐induced chromatin compaction and nuclear retention of clock mRNAs
Mature plasma cells: oval with abundant basophilic cytoplasm, perinuclear hof, round eccentric nuclei, "clock face" chromatin and indiscernible nucleoli Immature plasma cells: higher nuclear / cytoplasmic ratio, more abundant cytoplasm and hof region compared to plasmablastic, more dispersed chromatin, often prominent nucleoli.

"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 Perinuclear hof (prominent Gogli apparatus). Pale perinuclear crescentic - may be up to the size of the nucleus in active plasma cells. Note:
Clockdependent chromatin topology modulates circadian transcription
The chromatin at clock-controlled genes undergoes rhythmic modifications mediated by the activities of histone modifiers and chromatin-remodeling proteins, thus facilitating rhythmic gene expression over the 24-hour cycle [29-31]. There is accumulating evidence showing that these proteins interact with core clock components to impose temporal.
The plasma cell clockface or cartwheel nuclear pattern as seen in 2D
Definition Solitary lesions of clonal plasma cells that are cytologically, immunophenotypically, and genetically similar to plasma cell myeloma. Clinical Features Bone pain and cord compression due to vertebral lesions. Localization Dura-based (D.D. meningioma), intrasellar (D.D. pituitary adenoma), rarely intraparenchymal.

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.

summary 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%.

The well-differentiated or "mature" plasma cell (so called Marshalko-type) shows the characteristic round eccentric nuclei with "clock face" chromatin without nucleoli and abundant dense basophilic cytoplasm with clear perinuclear hof corresponding to the Golgi zone.
