[Risk of breast cancer of low differentiation in tumors with estrogen-negative receptors].

The risk for poorly differentiated invasive ductal carcinoma was evaluated in negative estrogen receptor tumors determined by immunohistochemical method. The results were correlated with the histological grade. The poorly differentiated tumors had a major risk (OR = 17.8) to be negative. A high risk of correlation was found between the estrogen receptor positivity and the well differentiated tumors (grade I), p = .0001. Our results are similar to other previous reports. The usefulness of this findings and its occasional role when it was not possible the determination of this receptor for lacking economical or technological resources is discussed.

[Spinal primitive neuroectodermal tumor].

The term primitive neuroectodermal tumor (PNET) names a group of malignant neoplasms of presumed neural crest origin; they are composed of round small cells, and may be centrally located or outside. The former are currently seen in childhood, mostly in reference to the posterior fossa, and include medulloblastoma and neuroblastoma. Outside of the central nervous system includes peripheral neuroectodermal tumor of the bone (PNET-B, Tefft's tumor), Askin's tumor, and even Ewing's sarcoma. We describe a case in a young adult, with extremely unusual spinal localization, in which histopathological and immunohistochemical analysis were done; also, a review of some features is presented clinical-histopathological issues concerning related.
