Primary Inferior Vena Cava smooth muscle tumor with diffuse bizarre giant nuclei and low mitotic rate: a nomenclatural conundrum

A male patient with obstructive jaundice was found to have an incidental nodule within the inferior vena cava (IVC), below the level of the renal vein, on abdominal imaging. At the time of the Whipple's procedure for pancreatic adenocarcinoma, the IVC mass measuring 3.4 x 2.7 x 2.2cm, was also removed.Histologically, the lesion was well-circumscribed, composed focally of spindle shaped cells with cigar-shaped nuclei reminiscent of smooth muscle, and a dominant pervasive, pleomorphic, bizarre giant cell component.
