Phenotype Image Detail
Image
Caption (A & B) The spleen of a Prkar1atm1Gsm/Prkar1a+ is enlarged by a tumor (white arrow). Histology shows splenic hemangiosarcoma with vascular channels lined by malignant endothelial cells (black arrows). (C & D) Left forelimb soft tissue mass (white arrow). Histology reveals myxoid fibrosarcoma comprised of highly anaplastic spindle cells (black arrows) with hyperchromatic enlarged nuclei and distinctive nucleoli dispersed in a myxoid stroma. (E & F) The liver (one lobe shown) has a multinodular (white arrows) appearance. Histology shows hepatocellular carcinoma with multiple nodules comprised of malignacy hepatocytes (black arrows) with loss of normal hepatic architecture. (G & H) Sarcoma mass involving the calvaria (white arrow) with distinct myxomatous areas (*). Insert in H: Typical stellate cell from myxomatous region. (I & J) Extradural lumbar chondrosarcoma causing compression and axonal degeneration in the spinal cord white matter (black arrow). Insert in J: A typical binucleated chondrocyte within the tumor. Scalebar: 50um B; 25 um D & F; 10 um H & J
