Solid tissue cell types

  1. Image Upload 1
    Lymphoma- MANY lymphoblast cells with prominent nucleoli
  2. Image Upload 2
    Eosinophilic inflammation (> 15% Eos)- think allergy, parasite, etc.
  3. Image Upload 3
    Mast cell- Mast cell tumors are common in dogs but we will also see them in inflammatory reactions, especially in skin, airway or reproductive tract. Remember that they are characterized by large numbers of purple granules and abundant cytoplasm.

    Lymph node aspirate
    Epitheliod cells in the lymph node is an inappropriate place for them to be. SCC metastasized to l.n.
  5. Image Upload 5
    Epitheliod cell pleomorphism. Much variability- signs of malignancy
  6. Image Upload 6
    Normal epitheliod cells. Uniform. Exceptions: Round cell tumors with be uniform.
  7. Image Upload 7
    Monotonous population of cells. Fibrosarcoma in a dog.
  8. Image Upload 8
    Epitheliod cells of a SCC. Inflammation is not typically present with the exception of SCC's because of keratin stimulation of an inflammatory rxn.
  9. Image Upload 9
    Cellular piling (may suggest malignancy)
  10. Image Upload 10
    Large, abnormal nuclei with abnormally clumped chromatin. Signs of malignancy.
  11. Image Upload 11
    Multiple, large nucleoli= malignancy
  12. Image Upload 12
    Multiple, large nucleoli= malignancy
  13. Image Upload 13
    Multiple, large nucleoli= malignancy
  14. Image Upload 14
    Cellular piling and variability= malignancy
  15. Image Upload 15
    Abnormal mitotic figures= malignancy
  16. Image Upload 16
    Abnormal mitotic figures= malignancy
