Abstract

We report a case of malignant peritoneal mesothelioma with parasternal lymph node metastasis. The patient was a 34-year-old man who presented with a history of several years of abdominal pain and ascites of unknown origin. Exploratory laparoscopic biopsies yielded histological findings of malignancy, but a final diagnosis was not able to be made. A chest computed tomographic scan done the following year showed a parasternal nodule, and thoracoscopically obtained biopsied material was positive for calretinin. These findings led to a pathological diagnosis of metastasis to the parasternal lymph node from peritoneal mesothelioma.
