Often neglected by large clinical trials, patients with uncommon breast malignancies have been rarely analyzed in large series.

Uncommon breast malignancies: presentation pattern, prognostic issue and treatment outcome in an Italian single institution experience.

Remission of autoimmune hyperthyroidism after chemotherapy for cancer.

Secondary breast angiosarcomas are a well-known entity generally characterized by a poor outcome, especially in patients with advanced disease. Among the drugs with demonstrated activity, taxane derivatives are one of the most effective histology-driven treatments against angiosarcomas. We report two cases of secondary breast angiosarcoma, both characterized by a very peculiar behavior towards paclitaxel. Both patients showed local recurrence of angiosarcoma after primary surgery, and they achieved complete remission following treatment with weekly paclitaxel. When a locoregional recurrence was observed as a result of a brief treatment interruption or a treatment delay, a new complete remission was rapidly achieved with the resumption of the drug, without evidence of any significant adverse effects.

Secondary breast angiosarcoma and paclitaxel-dependent prolonged disease control: report of two cases and review of the literature.

Noninvasive breast lesions encompass a heterogeneous group of risk indicators and nonobligate precursors of breast cancer, such as apocrine hyperplasia (AH) and columnar cell lesions (CCLs). Given the different expression of ER and ER-regulated genes in AH and CCL, these two alterations are currently considered discrete conditions. However, whether they share early biologic changes is not clear to date. Here, we sought to define the clinicopathologic and immunohistochemical features of a prospective series of combined lesions made up by CCLs and AH forming a continuum within single terminal duct-lobular units. The study group included 19 cases, whereas 25 cases of synchronous contiguous CCLs and AH served as control group. The different components of each case were subjected to immunohistochemical analysis for ER, PR, AR, HER2, BCL2, CCND1, MUC1, and PIP. Although CCLs and AHs arising in continuity showed opposite patterns of ER expression, the PIP-positive apocrine signature was consistently present in both components. In conclusion, apocrine changes are highly recurrent in CCLs growing within foci of AH, regardless of the ER activation. Our results suggest that PIP-positive and PIP-negative CCLs are likely to represent biologically distinct conditions and that apocrine changes might occur earlier than ER activation in the natural history of breast precursor lesions.
