Optimum duration of neoadjuvant letrozole to permit breast conserving surgery.

The aim of this multicenter, prospective, longitudinal phase IV study was to establish the optimal duration of neoadjuvant letrozole that would allow breast conservation surgery (BCS) in patients with early breast cancer who were initially unsuitable. Primary, invasive, estrogen-receptor- and/or progesterone-receptor-positive breast cancer patients, with large tumors (≥T2 i.e.

Osteoclast-like giant cell tumor arising in the soft tissue of the breast: report of a case.

Extraosseous manifestations of osteoclast-like giant cell tumors (OGCTs) in soft tissue are unusual, especially in the breast. However, multinucleated osteoclast-like giant cells have been described in association with epithelial malignancy, as a variant of breast carcinoma. We report a case of OGCT of the soft tissue of the breast, not associated with epithelial elements.
