Paravertebral malignant rhabdoid tumor in an adult. A case report with immunocytochemical study.
A case of paravertebral malignant rhabdoid tumor in a 59-year-old man is described. The location of the tumor and age of the patient appear to be unique. The clinical evolution was aggressive and resulted in the death of the patient. The tumor exhibited the light microscopic features of a typical rhabdoid tumor. It was composed of poorly differentiated round or polygonal cells with acidophilic glassy inclusions and vesicular nuclei exhibiting prominent nucleoli. Immunohistochemistry revealed the coexpression of cytokeratin and vimentin in neoplastic cells.
