title: Angiomyolipoma of the lung.
abstract: Extrarenal angiomyolipomas are rare tumors that have been reported in several organs, including the liver, reproductive organs, skin, and retroperitoneum. In this report, we present the clinicopathologic findings of an angiomyolipoma of the lung in a 67-year-old man with no history of tuberous sclerosis or lymphangioleiomyomatosis. To our knowledge, this is the second reported case of pulmonary angiomyolipoma. The tumor was coincidentally found in the left lower lung in association with a hemothorax. Our case was histologically identical to angiomyolipoma occurring in the kidney, but immunohistologic staining for HMB-45 was negative, similar to the first reported case.
