Malignant fibrous histiocytoma manifesting as a cavitary lung metastasis.
Exploration prompted by acute abdominal symptoms in a 29-year-old woman discovered to have an asymptomatic right upper lobe cavitary lesion disclosed a malignant fibrous histiocytoma, the primary lesion of which was in the duodenum. At autopsy, the lung lesion was found to be metastatic. We believe this is the first recorded instance of cavitary lung metastasis from this type of tumor.
