Another diagnostic challenge is presence of a heavy inflammatory infiltrate that obscures the neoplastic cells (Figure 4).
The neoplasm was composed of islands and trabeculae of neoplastic cells embedded in abundant loose fibrovascular stroma.
Multiple section studied shows tumour composed of neoplastic cells arranged in sheets, cords, tubules, cribriform, lobules and solid patterns (Figure 3).
Cases of disseminated neoplasia in bivalve mollusc species are characterized by the presence of large (2-4 times the diameter of normal hemocytes), neoplastic circulating cells that have a hyperchromatic and often pleomorphic nucleus containing 1 or more prominent nucleoli (Barber 2004), and a high nuclear-tocytoplasmic volume ratio in neoplastic cells (Mix 1975).
All positive neoplastic cells exhibited firmly fibrillary diffuse cytoplasmic staining using both TU-20 and TuJ-1 (Fig.
In conclusion, hypothyroidism, regardless of the functional state of the gonads, resulted in a delayed growth of the ascitic form of Ehrlich tumor as it reduced the liquid volume and did not reduce the number, viability, or diameter of neoplastic cells.
Furthermore, the neoplastic cells failed to react with histochemical stain, although the colloidal substances appeared pale.
On histopathologic examination, the mass was composed of a proliferation of neoplastic cells organized in dense sheets in a variably dense fibrous stroma.
Varying degrees of bone marrow interstitial involvement by the neoplastic cell infiltrate with reactive histiocyte hemophagocytosis are commonly seen in ANKL.
Microsatellite instability surveys since the 2010A survey period have asked laboratories to estimate both the percentage of neoplastic cells within the lesional area and the percentage of neoplastic cells for the entire section of tissue on a hematoxylin and eosin-stained glass slide.
