What are round cell tumors?

The term round cell tumor describes a group of highly aggressive malignant tumors composed of relatively small and monotonous undifferentiated cells with increased nuclear-cytoplasmic ratio.[1] Malignant small round cell tumors (MSRCT) is a term used for tumors composed of malignant round cells that are slightly larger …

Do round cell tumors spread?

Since DSRCT often is not diagnosed until the cancer is advanced, tumors grow large and spread through the lymph system or blood stream to other parts of the body. They can spread to many areas of the body, including the lymph nodes, lungs, bone and liver.

What are the six types of tumors on the round cell neoplasm category?

There are six types of round cell neoplasms: histiocytic tumors, lymphoma, mast cell tumor, transmissible venereal tumor, plasma cell tumor, and melanoma. These are very distinctive neoplasms, and they are easily identified cytologically.

Are histiocytes round cells?

On cytology, malignant histiocytes are large, pleomorphic discrete cells that contain abundant, often vacuolated, deeply basophilic cytoplasm. Nuclei are oval to reniform and contain lacy chromatin and prominent nucleoli.

Is round cell tumor curable?

What causes small round blue cell tumors?

Desmoplastic small round blue cell tumors (DSRCTs) originate from a cell with multilineage potential. A molecular hallmark of DSRCT is the EWS-WT1 reciprocal translocation.
