Histopathology and Cytology of
By Ivan Dinev, DVM, PhD
Fig. 1. The neoplastic changes begin always from B. Fabricii, where intrafollicular lymphomas (lim) of a various size are observed. H/E, Bar = 50 µm.
Fig. 2. Histologically, growth of singletype lymphoblast cells with marked pyroninophilia is observed. Tissue cross-section, liver, methyl green pyronin staining, H/E, Bar = 25 µm.
Fig. 3. Equal-sized lymphoblast cells. Touch imprint preparation, liver. Diff Quik, Bar = 10 µm.
Fig. 4. Lymphoid leukosis, spleen, hen. Growth of large lymphoid cells of a slightly varying size. H/E, Bar = 25 µm.
Fig. 5. Liver, lymphoid leukosis, hen. Focal growth of lymphoblasts, single lymphocytes, resulting in atrophy of the parenchyma. H/E, Bar = 25 µm.
