Reduced GATA3 expression during breast cancer progression: A potential anchor for pulmonary metastatic deposition.

Estrogen receptor (ER) is a direct and reciprocal target gene for GATA3. Previous studies have shown that higher GATA3 expression in primary breast cancer (BC) is associated with a reduced probability of developing lung metastasis when compared to those with metastatic recurrence to other organs. Further, GATA3 downregulates several genes promoting BC lung metastasis and upregulates genes encoding known inhibitors of lung metastasis.

Soft tissue hemangioma of the right upper extremity with intraosseous extension and secondary intravascular papillary endothelial hyperplasia.

Intravascular papillary endothelial hyperplasia (IPEH), also known as Masson's tumor, is an uncommon exuberant form of organizing thrombus that may occur within a vessel, vascular tumor, or hematoma and may change the imaging appearance to mimic an aggressive process. It must be distinguished pathologically from angiosarcoma. They have been most commonly reported within superficial soft tissue tumors, and rapid growth and effect on bone are rarely described.

p53 protein expression patterns associated with TP53 mutations in breast carcinoma.

Purpose: The importance of a TP53 mutation has been demonstrated in several tumor types, including breast cancer (BC). However, the accuracy of p53 protein expression as a predictor of gene mutation has not been well studied in BC. Therefore, we evaluated p53 protein expression associated with TP53 mutations in breast cancers from 64 patients.
