CT confirmed the presence of a locally recurrent mass not observed on the previous CT exam performed immediately postresection (Figure 1).
Rhabdoid cells grow in loosely cohesive sheets. 
The cells are rounded to ovoid, have rounded nuclei with prominent 
nucleoli; homogeneous, deeply, eosinophilic hyaline cytoplasmic inclusions displace 
the nucleus laterally (hematoxylin and eosin stain, X 600). A magnified part by electron microscopy shows that paranuclear spherical aggregates of intermediate filaments displace most organelles and the nucleus. No tonofilaments are present (original magnification is X 9660).

The tumor had brisk mitotic activity  (Figure 2). There were large whorls of intermediate filaments forming aggregates adjacent to the nucleus (Figure 2).
