[A patient with lymphoma of mucosa-associated lymphoid tissue (MALT) and adenocarcinoma in the same tumor of the lung].
A 60-year-old woman with no symptoms was found to have a mass shadow in the left lower lobe of the lung on chest radiography. Open lung biopsy and left lower lobectomy were performed. Histopathological study of the specimen revealed two distinct neoplasms. One tumor was a low grade B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) of the lung, while the other was an adenocarcinoma. The two neoplasms were admixed to form a composite tumor.
