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.

Ovoid intermediate-small cell size ~ 12 micrometers: Cells slightly larger than red blood cells and neutrophils. Eccentric nucleus. Nucleus usu. hugs the cell membrane. "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.
Cells decide when to divide based on their internal clocks EurekAlert! Science News
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.

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.

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.

Plasma cells have distinctive features that are clearly seen in this electron micrograph: a prominent Golgi; well developed rough endoplasmic reticulum; and a nucleus with large clumps of heterochromatin at the margin of the nucleus (clock-face nucleus). Compare these features with the high magnification light microscopic inset. Plasma cells.

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.

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:

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.

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.
