Abstract
Background: We examined the percutaneous aspiration cytology of 2 cases of pulmonary sclerosing hemangioma.
Cases: The first case was a 68-year-old female with hemoptysis, and the second a 40-year-old female with an abnormal shadow on her physical check-up chest X-ray.
We could not make a certain diagnosis by preoperative aspiration cytology for either case. The tumor was excised, and both were diagnosed as pulmonary sclerosing hemangioma. We reexamined the preoperative aspiration materials. Abundant hemosiderin-laden histiocytic cells were seen on a bloody background, and a few columnar or sheetlike clusters were detected, which consisted of round, pleomorphic or spindle-shaped cells. There were few fatladen histiocytes.
Conclusion: Several reports have emphasized the features of various kinds of cells characteristic of inprinted specimens of this tumor, but in percutaneous aspiration materials, numerous hemosiderin-laden histiocytic cells were conspicuous, which was thought to be a clue to the diagnosis of the disease.
