Primary breast lymphoma in the right breast during treatment for left breast cancer

Abstract Background Primary breast lymphoma is a rare condition, and distinguishing it from breast cancer is important because their treatments differ radically. Moreover, a recent report showed that mastectomy offered no benefit in the treatment of primary breast lymphoma. Case presentation A 59-year-old woman was treated with adjuvant chemotherapy and local radiation after surgery for left breast cancer. She presented with a rapidly growing mass in the right breast at 20 months after surgery. Mammography and computed tomography revealed a massive tumour. She was diagnosed with primary breast lymphoma by aspiration cytology, and surgery was performed. Histopathological and immunohistochemical findings confirmed a diffuse large B-cell type primary breast lymphoma. Conclusion In this case, the lymphoma exhibited rapid growth despite chemotherapy for a malignancy in the contralateral breast. The patient had developed bronchiolitis obliterans organizing pneumonia due to radiation. Therefore, surgical treatment of the lymphoma was selected.</p

Laparoscopic Repair of Incarcerated Diaphragmatic Hernia as a Late Complication of Laparoscopic Right Hepatectomy : A Case Report

腹腔鏡下肝切除術は保険適応となり普及してきている．腹腔鏡下肝切除における重篤な合併症の報告は少ない．今回，腹腔鏡下肝右葉切除術20ヶ月後に発生した横隔膜ヘルニア嵌頓に対して，腹腔鏡下に嵌頓を解除し横隔膜縫縮術を施行した症例を経験したので報告する．Incarcerated diaphragmatic hernia after laparoscopic right hepatectomy is very rare. An 81-year-old man underwent laparoscopic right hepatectomy for giant hepatic hemangioma. Twenty months after the surgery, he began to complain of nausea and abdominal pain and was brought to our hospital. Chest X-ray showed an abdominal gas shadow above the right diaphragm and computed tomography showed herniation of the colon into the right thoracic cavity. We diagnosed ileus due to incarcerated diaphragmatic hernia and performed emergency operation under laparoscopic surgery. After successfully reducing the prolapsed colon back to the abdominal cavity, the diaphragmatic hernia orifice was repaired. Incarcerated diaphragmatic hernia sometimes causes the fatal state. Clinicians must therefore consider such findings a late complication of laparoscopic hepatectomy
