Axillary lymph node metastasis from colorectal carcinoma is extremely rare, and this scarcity hinders understanding of its pathogenesis and, thus, the application of appropriate management. Here, we present a case with axillary lymph node metastasis of cecal carcinoma associated with macroscopic invasion of the skin of the abdominal wall with histological evidence of such invasion, findings which support our hypothesis that the axillary lymph node metastasis developed via the lymph channels in the skin of the abdominal wall. A 76-year-old woman with cecal carcinoma (T4N1M0), complicated with an abdominal wall abscess, underwent right hemicolectomy with partial resection of the abdominal wall.

We report a 39-year-old man with intravascular large B-cell lymphoma (IVLBCL) who had been treated as a case with pulmonary arterial hypertension (PAH) for one year. After he became worse, diffuse pulmonary (18)F-fluorodeoxyglucose (FDG) uptake in positron emission tomography (PET) suggested the existence of IVLBCL in the lung showing normal CT images. The diagnosis was confirmed with random transbronchial lung biopsy, and he was then successfully treated.

Background: Previous studies have demonstrated that atheroembolism during percutaneous coronary intervention is associated with myocardial damage. The purpose of this study is to investigate the clinical and angiographic characteristics related to removable plaque elements in patients undergoing thrombectomy for myocardial infarction.

Methods: Eighty consecutive lesions in 80 patients (M/F=58/22, age 65.

Aim: To elucidate risk factors contributing to the development of hepatocellular carcinoma (HCC) among patients with sustained viral response (SVR) after interferon (IFN) treatment and to examine whether HCV-RNA still remained in the liver of SVR patients who developed HCC.

Methods: Two-hundred and sixty-six patients, who achieved SVR, were enrolled in this study. We retrospectively reviewed clinical, viral and histological features of the patients, and examined whether the development of HCC depends on several clinical variables using Kaplan-Meier Method.
