Plasmacytomas are a localized proliferation of plasma cells in the bone marrow and soft tissue. Extramedullary plasmacytomas are rare and typically solitary plasma cell neoplasms originating from extraosseous organs and tissues. A 31-year-old woman was referred to our hospital with a rapidly growing abnormal shadow on a chest roentgenogram. Chest computed tomography showed that the lesion was located in the anterior mediastinum. She underwent surgery, and the tumor was diagnosed as an extramedullary plasmacytoma. She remains well 2 years postoperatively without recurrence. An extremely rare case of an anterior mediastinal extramedullary plasmacytoma is presented.
Occurrence of bronchial artery aneurysm is rare, and it has been detected in less than 1 % of all selective bronchial arteriography cases. Here, we present a case of a bronchial artery aneurysm caused by a tracheal stent migration. A 59-year-old man was operated on for esophageal cancer, where an esophageal-tracheal fistula occurred 1 week after operation. Surgical repair of the esophageal-tracheal fistula was performed using a muscle flap, but this not results in fistula closure. Consequently, a self-expanding covered metallic tracheal stent was implanted for rescue, and this resulted in fistula closure. After 1 year, there was frequent hemoptysis caused by migration of the stent. He was referred to our hospital where removal of the stent was planned. A sudden occurrence of massive bleeding from trachea occurred, and extracorporeal membrane oxygenation (ECMO) was used. Although removal of tracheal stent was performed successfully, the patient subsequently died from multi-organ failure. Post-mortem autopsy revealed that the massive bleeding is originated from the rupture of a bronchial artery aneurysm.
<b><i>Background:</i></b> Normal bronchial epithelium has been described in terms of transparency and smoothness. No studies have compared bronchoscopic and pathological findings in the identification of bronchial epithelium. <b><i>Objectives:</i></b> This study aimed to classify bronchoscopic findings for peripheral pulmonary tumour (PPT) for accurate bronchoscopic diagnosis accounting for the presences of bronchial epithelium and bronchial stenosis using an ultrathin bronchoscope. <b><i>Methods:</i></b> We performed endocytoscopy using narrow-band imaging (NBI) of specimens immediately after lobectomy to investigate the normal bronchial epithelium under the physiological saline injection technique (PSIT) prior to classification of PPT. A retrospective study to classify bronchoscopic findings included 46 patients diagnosed with malignancy by bronchoscopy for PPT. <b><i>Results:</i></b> We recognized a “light blue line” (LBL) with NBI under PSIT, corresponding to strong reflection of short-wavelength light by cilia on the epithelial surface in an ex vivo endocytoscopic study. Bronchoscopic findings of PPT were classified morphologically into stenotic type (ST) and non-stenotic type (NonST). Tumours were also classified as exposed type (ET) and non-exposed type (NonET) based on the presence of epithelium. Most ST and NonET lesions (74%) were adenocarcinoma. Among squamous cell carcinoma, 55% were categorized as ST and ET. All NonST and NonET cases were adenocarcinoma. A significant difference in the presence of LBL was seen between ET and NonET. <b><i>Conclusions:</i></b> Our simple classification based on the appearance of stenosis and LBL in PPT may facilitate pathological diagnosis.
