Caption: Figure 3: Histopathologic findings: (a) intermediate magnification of "jigsaw pattern" with biphasic cell nests showing outer somewhat palisaded small blue cells and central basaloid cells with slightly more abundant eosinophilic cytoplasm as well as fibrous stroma, H&E stain, 200x; (b) basement membrane material investing periphery of epithelial nests, PAS stain, 200x.
The basal and peritrophic membranes exhibited a moderate reaction to PAS, allowing their identification; whereas the regenerative cell nests and muscle layers were negative for this histochemical test (Fig.
Gonads destined to be males were identified by duct structures within the gonad lobe as well as by more elongated germ cell nests. These morphologically distinct features resulted in an early demonstration of the corradiating pattern of ducts and lobules seen in more advanced testes.
B, High-power photomicrograph showing spindle and epithelioid cell nests with intermixed osteoid formation.
Microscopically, tumorous tissue revealed proliferating squamous cell which were characterized by presence of epithelial pearls and cell nests. Electron microscopic examination of tumorous tissue revealed pleomorphic epithelial cells with enlarged nuclei.
