HER2-Positive Metaplastic Breast Cancer with Resistance to Neoadjuvant Chemotherapy: Case Report.

Introduction: Metaplastic breast carcinoma (MBC) is a rare histologic subtype of breast carcinoma, which is usually negative for estrogen receptor, progesterone receptor, and HER2. HER2-positive MBC is therefore extremely rare. Most MBCs have poor response to chemotherapy.

Pulmonary vein thrombosis following a right upper lobectomy preceding acute arterial occlusion: a case report.

Our medical team observed a right upper lobe nodule in a 78-year-old man who was treated with warfarin for chronic atrial fibrillation. The nodule was diagnosed as adenocarcinoma via intraoperative frozen sectioning. We performed video-assisted right upper lobectomy and mediastinal lymph node dissection.

Combination treatment by the cervical approach with mediastinal drainage and continuous saline irrigation for descending necrotizing mediastinitis type IIb: a three-case series.

Descending necrotizing mediastinitis (DNM) is a severe, life-threatening disease and requires prompt treatment. The primary treatment for DNM is cervical and mediastinal drainage in addition to antibiotic treatment. However, the most appropriate drainage approach and the effectiveness of additional treatment remain unclear.

Granulation after stenting for tuberculous bronchial stenosis treated with tranilast: A case report.

A 63-year-old woman was diagnosed with tuberculous bronchial stenosis of the left main bronchus following recurrent pneumonia. She underwent airway dilatation and stenting for long and severe stenosis. Initially, a Dumon Y-stent was implanted, but repeated granulation occurred at the distal end of the stent.

Resection of a capillary haemangioma using robotic-assisted thoracic surgery: A case report.

Capillary haemangioma is a rare condition that is difficult to diagnose preoperatively because of its rarity and nonspecific imaging findings. In this report, we describe a case of capillary haemangioma diagnosed by robot-assisted thoracic surgery (RATS). A 72-year-old man was incidentally found to have an anterior mediastinal tumour on chest computed tomography.

A rare case of thymoma with CA 19-9 production.

A 72-year-old man was diagnosed as having myasthenia gravis (MG). He underwent computed tomography which revealed an anterior mediastinal tumour. Laboratory examination revealed elevated levels (106.
