title: [Pulmonary metastasis of extranodal high malignancy B-cell non-Hodgkin lymphoma of the bulbus duodeni and pylorus of the stomach].
abstract: We report a 71-year-old female patient with repeated vomitus, meteorism, epigastric pain and reflux for more than four month. She had a palpable mass in the upper abdomen and lost 7 kg of weight during the last four months. Chest X-ray showed two masses, 2 cm and 3 cm in diameter, in the left and right lower lung. A stenosing polypoid mucosal swelling in the antrum and the duodenal bulb. The pulmonal masses were biopsied under CT-guidance. Biopsy proved a high malignant B-cell non-Hodgkin's lymphoma of the stomach. The masses in the lung were identified as metastases of the gastrointestinal lymphoma. In conclusion on this tumor was an extranodal non-Hodgkin's lymphoma stadium BE IV according to Musshoff. A CHOP-chemotherapy was initiated. Restaging after three cycles of CHOP revealed a complete remission. Primary gastrointestinal non-Hodgkin's lymphomas are relatively rare neoplasms of the abdomen. Unusual and interesting in this case ist the metastatic pattern involving the lung periphery without local lymph node metastases.
