A case of contralateral inguinal lymph node metastases from breast cancer.

Background: Breast cancer is well known to tends to invade through the lymphatic chains mainly to the axillary and subclavian nodes or occasionally to the internal mammary nodes. However, inguinal lymph node metastasis from breast cancer is extremely rare.

Case Presentation: We have experienced a case of an 82-year-old woman showing left inguinal lymph node metastases from right breast cancer.

Prediction of pathological complete response after neoadjuvant chemotherapy in breast cancer by combining magnetic resonance imaging and core needle biopsy.

Background: Pathological complete response (pCR) is often achieved by neoadjuvant chemotherapy (NAC), particularly in hormone receptor-negative breast cancer. Contrast-enhanced magnetic resonance imaging (cMRI) is the most reliable imaging modality to evaluate the pathological effect of NAC. Ultrasonography is indispensable to collect representative specimens from the target lesion by core needle biopsy (CNB).

Chyle leakage after axillary node sampling in a patient with breast cancer: a case report.

Background: Chyle leakage is a well-known complication after thoracic surgery, such as esophagectomy, cardiac surgery, mediastinal lymph node dissection, and neck surgery. However, chyle leakage is a rare complication after dissections of the lateral or subclavian axillary nodes for breast surgery. It is particularly unusual for chyle leakage to occur after minimally invasive dissection of the axillary nodes.

[A case of peritoneal serous papillary carcinoma].

A 65-year-old female was admitted to our hospital with abdominal distension. Abdominal CT and MRI revealed massive ascites and an omental cake, but the ovaries were of normal size. After an omentum biopsy was performed during open abdominal surgery, she was diagnosed as peritoneal serous papillary adenocarcinoma.
