Unilateral methotrexate-induced lung injury with foreign bodies in the airway: A case report.

A 75-year-old woman who had been taking methotrexate presented to our hospital for fever and dry cough. Chest computed tomography showed ground-glass opacity in the upper lobe of the right lung and foreign bodies in the lower lobe of the right bronchus. During bronchoscopy, foreign bodies were removed from the airway.

Pulmonary Malignant Ameloblastoma without Local Recurrence 31 Years after Primary Resection: A Case Report and Literature Review.

A 78-year-old man with a history of surgical resection for ameloblastoma 31 years earlier visited our hospital for prolonged cough. Chest computed tomography showed multiple nodules in both lungs. Although there was no local recurrence in the mandible, the specimen taken from a transbronchoscopic bronchial biopsy showed recurrent ameloblastoma.

Promising Effects of Afatinib on Leptomeningeal Carcinomatosis Derived from Erlotinib-resistant Lung Adenocarcinoma.

We herein report a case of a 67-year-old woman previously treated with erlotinib for adenocarcinoma with an epidermal growth factor receptor (EGFR) mutation in exon 19, which rapidly developed to progressive symptomatic leptomeningeal carcinomatosis. The primary tumor and lung metastases also worsened and the performance status (PS) score declined to 3. With a re-biopsy from the pulmonary metastases, the T790M mutation was detected by the cobas EGFR mutation test, but not the cycleave test, although an exon 19 deletion was detected by both of the tests.

[A case of Carboplatin and pemetrexed combination chemotherapy for synchronous double cancers of hepatocellular carcinoma and primary lung cancer].

A 78-year-old man presented to our hospital with lung abnormality on his chest radiograph. Computed tomography (CT) showed a mass and obstructive pneumonia in the right upper lobe of the lung. The mass was diagnosed as a pulmonary adenocarcinoma with a bronchoscopy (cT4N2M0, Stage IIIB).

[A case of advanced gastric cancer with carcinomatous lymphangitis of the lung treated with docetaxel and S-1 combination chemotherapy].

A 67-year-old woman with complaints of cough and dyspnea was admitted; her chest radiographs and computed tomography (CT) scans revealed pulmonary carcinomatous lymphangitis. Endoscopic examination revealed advanced gastric cancer and the patient was treated with a combination of 40 mg/m2 docetaxel, administered on day 1, and S-1 100 mg/body/day, administered for 14 days followed by a 7-day interval, as 1 course despite her performance status( PS) being grade 3. After 2 courses of chemotherapy, CT showed that the carcinomatous lymphangitis had improved, and the patient was discharged with PS of grade 0.

[Sustained remission of blastic plasmacytoid dendritic cell neoplasm with ABVD chemotherapy].

Blastic plasmacytoid dendritic cell neoplasm is a rare but clinically aggressive tumor known to be derived from the precursors of plasmacytoid dendritic cells with frequent cutaneous involvement. Though the majority of patients initially respond to multi-agent chemotherapy, most cases without hemopoietic stem cell transplantation relapse within a year. We describe a case of a 71-year-old man with a dark-purple subcutaneous nodule (5×3 cm) under his right auricle.
