Pleomorphic neuroblastoma

A focus of pleomorphic uni-nucleated and multi-nucleated giant cells.

Some pNTs contain foci of pleomorphic, uni-nucleated or multi-nucleated, giant cells of uncertain prognostic significance.

Pleomorphic neuroblastoma diffusely composed of markedly pleomorphic cells.

Pleomorphic neuroblastoma is composed of diffusely distributed pleomorphic and bizarre cells with markedly hyperchromatic single or multiple nuclei.
