Pathology Image Detail

Caption	Central portions of the neoplasm (solid with early stage of pseudoglandular pattern): the neoplasm is composed of very thick coalescing trabeculae separated by a small amount of loose fibrovascular stroma. Numerous neoplastic cells undergo single cell necrosis which results into the formation of small punched-out areas in the neoplastic trabeculae, a pattern known as "pseudoglandular pattern". Mitotic rate is high.
