T cell type immunoblastic sarcoma diagnosed primarily by CSF cell membrane features.
The case of a 65 year-old female with an immunoblastic sarcoma of T cell type (reticulosarcoma) is reported. Post mortem tumor cell infiltrations with the typically histomorphological criteria of an immunoblastic sarcoma were found in the uterus, bone marrow and leptomeninges. With the aid of immunological markers the T cell type of this malignant lymphoma was diagnosed intra vitam on the basis of CSF cells. Until now, only one case of an immunoblastic sarcoma of the T cell type has been described in the literature.
