CABRERA MORALES, C. M.. Tumor desmoplásico de células pequeñas y redondas (DSRCT) de riñón. Oncología (Barc.) [online]. 2005, vol.28, n.5, pp.38-42. ISSN 0378-4835.

Desmoplastic small round cell tumor is a rare disease consisting of a form of peritoneal surface malignancy usually affecting young males, composed of relatively small and undifferentiated cells with a high nuclear-cytoplasmic ratio. The co-expression of epithelial, muscular and neuronal antigens distinguishes this entity from other small round cell tumors. The t(11;22)(p13;q12) translocation is a recurrent characteristic of this type of tumor. However, we report a new case of desmoplastic small round cell tumor of the kidney affecting a 20 year old male where the t(11;22)(p13;q12) is absent.
