A 64-year-old man who underwent sigmoid resection for Stage 4 colon cancer had a growing nodule on the left upper lobe during follow-up. Surgical resection revealed primary pulmonary adenocarcinoma. Subsequently, a new nodule appeared in the contralateral S(1)b, for which endobronchial ultrasonography with a guide sheath (EBUS-GS) was performed for diagnosis. However, histopathologic examinations were inconclusive. Gene analysis of the liquid samples from this lesion revealed KRAS mutation, which on hindsight was not detected in the metachronous left upper lobe cancer but was detected in the resected sigmoid colon. Hence, the right upper lobe nodule was diagnosed by bronchoscopy as colon cancer metastasis, confirmed after wedge resection. For specimen obtained by EBUS-GS, search for gene mutation in the liquid specimen is useful as an ancillary test especially when histological diagnosis is equivocal. Thus, developments on diagnostic tools using liquid samples are highly expected in the future.

A 75-year-old male with a history of alcoholic liver cirrhosis, sigmoid colon cancer, and metastatic liver cancer was admitted to our institution with a complaint of a prickly feeling in his chest. On admission, a chest radiograph revealed a normal cardio-thoracic ratio of 47%. Echocardiography revealed pericardial effusion and blood chemical analyses revealed elevated C-reactive protein levels (14.7 mg/dL). On day 3, chest radiography revealed cardiomegaly with a cardio-thoracic ratio of 58% and protrusion of the left first arch. Contrast-enhanced chest computed tomography revealed a saccular aneurysm in the aortic arch with surrounding hematoma; thus, a ruptured thoracic aortic aneurysm was suspected. Emergency surgery was performed, which revealed a ruptured aortic aneurysm with extensive local inflammation. The diagnosis of an infected aortic rupture was therefore confirmed. The aneurysm and abscess were resected, followed by prosthetic graft replacement and omental packing. Histopathology of the resected aneurysm revealed gram-positive bacilli; and Listeria monocytogenes was confirmed as the causative organism by culture. Postoperative course was uneventful; on postoperative day 60, the patient was ambulatory and was discharged. Here we report the case of a male with a ruptured thoracic aortic aneurysm infected with L. monocytogenes.

Two cases of successful primary closure of a bronchopleural fistula with favorable infection control using latissimus dorsi musculocutaneous flaps are reported. Case 1 was a 70-year-old man who underwent resection of the right lower pulmonary lobe due to right lung metastasis of sigmoid colon cancer. A bronchopleural fistula was found on day 28 after surgery. Infection was controlled by antibiotic administration and tube drainage. Closure of the bronchopleural stump, thoracoplasty and plombage of latissimus dorsi muscles were performed for single-stage closure without open treatment, based on a negative pleural effusion culture. Case 2 was a 64-year-old man who underwent right lower pulmonary lobe resection due to right lung cancer. A bronchopleural fistula was found on day 14 after surgery. In single-stage closure, thoracoplasty and plombage of latissimus dorsi muscles were performed due to infection control and a negative pleural effusion culture. Both cases had a good postoperative course.

This report describes the case of a 57-year-old man with an anterior mediastinal tumor. Four years previously, he underwent laparoscopic anterior resection for sigmoid colon cancer. Thirty months after that procedure, bilateral pulmonary metastasectomy was performed. Twelve months later, follow-up computed tomography revealed a 1-cm pulmonary nodule on the upper lobe of the right lung and a solid mass on the anterior mediastinum, and the patient was also observed to have an elevated serum carcinoembryonic antigen (CEA) level. Repeated pulmonary nodule resection and total thymectomy were performed. Immunohistochemical staining of the anterior mediastinal tumor revealed adenocarcinoma, and his serum CEA level returned to normal after the operation. These findings strongly suggested metastatic thymic adenocarcinoma from a colorectal cancer.

5-Fluorouracil is a key element to the treatment of colon cancer. But it is also one of the most cardiotoxic chemotherapies, and the management of those that experience cardiotoxicity can be challenging. We present three cases of 5-FU cardiac toxicity that manifested as myocardial infarction, cardiogenic shock, and ventricular fibrillation. Additionally, we discuss the current literature regarding 5-fluorouracil cardiotoxicity mechanisms as well as management.
