Superior vena cava syndrome as unilateral right breast enlargement.

This case report describes a postmenopausal woman presenting to the breast surgery clinic with right breast enlargement, new spider veins on the chest, dyspnea, and facial swelling. She was treated for lung cancer. Imaging showed her right hilar mass causing critical superior vena cava (SVC) stenosis. She was transferred to thoracic surgery, underwent SVC stent placement, and her symptoms improved. SVC syndrome as a cause of right breast enlargement is unusual; therefore, carefully reviewing symptoms, medical history, and physical examination is crucial for diagnosis.

Pregnancy-associated breast cancer patients can safely undergo lymphatic mapping.

As more women put off pregnancy until their 30s and beyond, the possibility of pregnancy-associated breast cancer (PABC) will rise. Treatment options for patients with PABC need to consider possible harm to the fetus. The goal of this study is to review our institution's experience with sentinel lymph node (SLN) biopsies in patients with PABC. A prospectively accrued breast Institutional Review Board (IRB) approved data base was searched under separate IRB approval for cases of SLN biopsy in patients with PABC. Ten patients were identified between 1994 and 2006 out of 5,563 patients. A chart review was performed on all 10 patients. Ten patients with PABC and an average gestation age of 15.8 weeks underwent SLN biopsy. All patients successfully mapped. Positive SLN were identified in 5/10 patients (50%) while there was no evidence of metastases in 5/10 patients (50%). 9/10 (90%) of patients went on to deliver healthy children without any reported problems. One patient (10%) decided to terminate her pregnancy in the first trimester following surgery prior to the start of chemotherapy. SLN biopsy can safely be performed in patients with PABC with minimal risk to the fetus. By performing a SLN biopsy, a large proportion of patients with PABC may be spared the risk of a complete axillary lymph node dissection.

Problems with the use of breast conservation therapy for breast cancer in a patient with neurofibromatosis type 1: a case report.

Patients with neurofibromatosis type I and breast cancer represent a subset of people who may be considered at high risk for secondary cancers after conventional whole breast radiation therapy and breast conservation surgery. A case of a 49-year-old woman with neurofibromatosis type I is presented. She was diagnosed with a 1.1-cm right breast infiltrating ductal carcinoma. Clinical, diagnostic imaging, and pathologic features are discussed. Her initial treatment plan of breast conserving therapy was thwarted when her sentinel node biopsy was positive for micrometastatic disease in 1/14 lymph nodes. She elected to have a bilateral simple mastectomy. This case addresses the rare dilemma of offering breast conservation therapy as a viable option for patients with neurofibromatosis type I. Current data on radiation-induced secondary cancers such as sarcoma after treatment for breast and other cancers are reviewed.
