Cytology round cells

  • Can round cells be benign?

    Cutaneous round cell tumors range from potentially self-resolving benign lesions (canine cutaneous histiocytoma) to aggressive malignancies (cutaneous lymphoma)..

  • What are round cells?

    noun. : a small lymphocyte or a closely related cell especially occurring in an area of chronic infection or as the typical cell of some sarcomas..

  • What are the round cells?

    Leucocytes and immature germ cells present in semen are collectively defined as “round cells” (2)..

  • What are the shapes of cells in cytology?

    Normal cells have more cytoplasmic than nuclear area (with some notable exceptions such as small lymphocytes).
    The nuclei of normal cells are usually round or oval shaped.
    Malignant cell nuclei are often odd shaped with irregular contours (pleomorphic)..

  • What is the difference between round and mesenchymal cells?

    Epithelial cells are round to polygonal and have a tendency to arrange in cohesive clusters.
    Mesenchymal cells often have one or more cytoplasmic tails.
    Those with one cytoplasmic tail may be described as flame shaped, those with two as spindle shaped, and those with more than two as stellate shaped..

  • Desmoplastic small round cell tumor (DSRCT) is a rare but highly aggressive neoplasm that afflicts mainly adolescents and young adults.
    The most common location is the peritoneal cavity, although tumors arising from other sites have been described.
  • Epithelial cells are round to polygonal and have a tendency to arrange in cohesive clusters.
    Mesenchymal cells often have one or more cytoplasmic tails.
    Those with one cytoplasmic tail may be described as flame shaped, those with two as spindle shaped, and those with more than two as stellate shaped.
Discrete (round) cell neoplasms. Discrete or round cell tumors often are of hematopoietic origin (lymphoma, histiocytic, mast cell tumor) and as the term suggests, consists of individualized round cells. Cells tend to exfoliate readily and aspirates are often of high cellularity.

The cells are often round with round nuclei, though some epithelial neoplasms, such as squamous cell carcinomas, can have atypical shapes.

What are the cytologic characteristics of round cell neoplasms?

Specific cytologic characteristics of round cell neoplasms include:

  1. the following:
  2. Round (discrete) cell neoplasm

Tissue aspirate.
Dog.
Discrete cells with a round shape, distinct cytoplasmic borders, and a very high nuclear-to-cytoplasmic ratio are characteristic of lymphoid cells.
This sample is taken from a lymph node effaced by lymphoma cells.

What are the results of cytology preparations?

Results of cytology preparations can indicate the number of cells present, the type of cell and the differential, the presence of tumor cells, and the presence of bacteria.
They can also give an indication of viscosity.

What is a round cell tumor?

Round cell tumors include:

  1. mast cells
  2. plasma cells
  3. lymphocytes
  4. histiocytic cells
  5. transmissible venereal tumor cells

Mast cells have distinctive granules within the cytoplasm and are usually easily identified; if they are the dominant cell type, this is diagnostic for a mast cell tumor.
,

What is cytologic material?

KEY POINT Interpretation of cytologic material may include:

  1. more than one category
    2. such as :>
  2. inflammation along with a response to tissue injury or neoplasia with inflammation

Normal tissue is generally composed primarily of mature cell types, although some organs such as:integumentary normally contain immature basal epithelium.
