We report an extremely rare case of pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma with a pulmonary arteriovenous fistula (PAVF). A 60-year-old woman with vulvar carcinoma was admitted to our hospital for further examination of an abnormal shadow on chest computed tomography (CT). She showed hypoxemia in the arterial blood gas analysis. (18)F-Fluorodeoxyglucose positron emission tomography (FDG-PET) showed consolidations in the left lower lobe and soft-tissue density lesions in the anterior mediastinum. Each lesion showed heterogeneous FDG uptake. Although needle biopsy of these lesions was performed, a pathological diagnosis was not obtained. For the evaluation of hypoxemia, chest contrast-enhanced CT was performed, and a PAVF in the consolidation of the left lower lobe was revealed. For diagnostic and therapeutic purposes, we performed left lower lobectomy under video-assisted thoracoscopic surgery. In the surgical specimen the PAVF measured 3 cm, and histopathological examination revealed pulmonary MALT lymphoma adjacent to the PAVF.

A CASE OF SCHWANNOMA OF THE MESOSIGMOID SHOWING HIGH RADIOTRACER CONCENTRATION ON FDG-PET

SHIEN Kazuhiko, KUBO Yoshiro, KOBATAKE Takaya, NOZAKI Isao, TANADA Minoru, KURITA Akira

The journal of the Japanese Practical Surgeon Society 71 ( 2 ) 541 - 545 2010.2

Language：Japanese Publisher：Japan Surgical Association

We report a case of a benign mesosigmoid schwannoma showing high radiotracer concentration on FDG-PET. A 66-year-old woman was admitted for abdominal pain. Computed tomography showed a 5-cm mass in the abdomen ; the FDG-PET examination showed a high radiotracer concentration. Malilgnant lymphoma or abdominal mesenchymal tumor was thought to be the most likely diagnosis. The tumor was resected. The inferior mesenteric artery was involved. On histopathology, the tumor was found to be composed of spindle-shaped cell bundles ; it was S-100 protein-positive, CD34-negative, CD117-negative, and α-SMA-negative. There were no findings suggestive of malignancy. A final diagnose of a benign mesosigmoid Schwannoma was made.

We report two cases of esophageal schwannoma. A 66-year-old woman (case 1) and a 56-year-old man (case 2) were admitted for abnormal shadows pointed out in barium esophagography. In case 1, an esophageal sub-mucosal tumor was resected by transthoracic esophagectomy with gastric tube reconstruction. In case 2, esophageal tumor was enucleated by thoracoscopic surgery. To remove the tumor from the muscular layer, a Sangstaken-Blakemore tube (S-B tube) was used intraoperatively inserted into the esophagus preoperatively. Both tumors consisted histopathologically of spindle-shaped cell bundles and S-100 protein expression was im-munohistochemically confirmed in both tumors. The definitive diagnose was benign esophageal schwannoma in both cases. Esophageal schwannoma is extremely rare, and we review 26 cases from the Japanese literature. © 2010 The Japanese Society of Gastroenterological Surgery.

呼吸器周術期の上室性不整脈に対するランジオロール塩酸塩の使用経験

呼吸器術後に発生した上室性不整脈に対するランジオロール塩酸塩の使用経験を報告した。症例は56歳男で、検診の胸部X線写真で異常を指摘された。気管支カメラの生検で扁平上皮癌と診断され、手術を施行した。#10、11リンパ節が腫大し転移が疑われたので、予定どおり左肺全摘を行った。術後8時間より心房組動を発症した。ジギタリスを使用したが効果なく、ランジオロール塩酸塩を0.01mg/kg/minで開始し、漸増し、0.04mg/kg/minで洞調律に戻ったため中止した。中止約2時間後、再度心房細動あり、ランジオロール塩酸塩投与を再開し、洞調律に戻った。その他3例のランジオロール塩酸塩の使用を経験し、ランジオロール塩酸塩にて、血圧低下なく心拍数をコントロールできた。また、投与前後で酸素飽和度の変化はなく、呼吸状態に対し影響はないようであった。

肺癌、特に早期の非小細胞肺癌に対する治療において外科的切除は重要な位置を占める。医学の進歩により胸腔鏡を用いた手術、また、非浸潤肺癌に対する積極的縮小手術、術前導入療法、術後補助療法の付加など手術を取り巻く環境も次第に変化している。本稿では岡山大学で行っている肺癌手術を中心とした肺癌への取り組みについて述べる。(著者抄録)

A case of metachronous brain metastases from gastric cancer with no recurrence Reviewed

A 75-year-old man with acute myeloid leukemia brought to complete remission by systemic chemotherapy was diagnosed by gastrointestinal endoscopy with advanced gastric cancer of the upper stomach during examination for severe anemia. He underwent total gastrectomy with D2 lymphadenectomy. One year and 5 months later, he underwent magnetic resonance imaging (MRI) of the brain due to changes in personality and vomiting. MRI showed three cerebral metastases, but computed tomography (CT) of the chest and abdomen and ultrasound imaging of the abdomen found no other metastasis. Tumor markers were within normal limits. The brain tumor was biopsied because acute myeloid leukemia recurrence could not be ruled out, and histopathological examination showed moderately differentiated adenocarcinoma consistent with gastric cancer, yielding a definitive diagnosis of brain metastases from gastric cancer. He underwent cyberknife radiosurgery to lessen clinical symptoms and was discharged. Although a second cyberknife radiosurgery was required for two brain metastases 5 months after initial radiosurgery, he is doing well without evidence of metastases to the brain, chest, or abdomen, one year after the diagnosis of brain metastasis. ©2008 The Japanese Society of Gastroenterological Surgery.
