Final answer:
Plasmacytes with Russell bodies are referred to as Mott cells, cells with Morular inclusions, or grape cells. These terms describe plasma cells with heavy accumulations of immunoglobulins, appearing as eosinophilic inclusions in the cytoplasm.
Step-by-step explanation:
A plasmacyte with Russell bodies is known by several names depending on its appearance and the context in which it is being discussed. The presence of Russell bodies indicates that a plasma cell is producing a large amount of immunoglobulins, which can accumulate in the form of eosinophilic inclusions within the cytoplasm. This situation can give rise to three common terminologies:
- Mott cell: The most commonly used term, it refers to plasma cells filled with spherical inclusion bodies (Russell bodies).
- Plasma cells with Morular inclusions: This is another term used to highlight the morphology of the inclusions, likening them to morula, which is an early stage in embryonic development where cells resemble a mulberry.
- Grape cell: This name is used less often but conveys a similar visualization of plasma cells crowded with inclusions, giving them a grape-like appearance.
These terms are often used in the field of hematology and pathology to describe variations of plasma cells under microscopic examination.
