ABSTRACT
So-called sclerosing hemangioma of the lung is a rare benign neoplasm which usually presents with a coin lesion detected through routine chest X-ray. We report two cases showing characteristic cytologic appearances which have been rarely reported. Both cases were young females with coin lesions in the lung. Fine needle aspiration of each case revealed unique but some different cytologic features. Case 1 showed bland-looking polygonal epithelial cells resembling bronchioloalveolar cells having predominantly papillary configurations with loosely arranged solid sheets or isolated cells. Cytoplasms were plump, cyanophilic, and finely granular, with eccentric nuclei. The nuclei were usually monotonous, round-to-ovoid, and vesicular with a small but conspicuous nucleolus. In comparison to case 1, case 2 revealed largely loose pavement-like solid sheets or clusters rather than papillary patterns in the hemorrhagic background. The size of tumor cells were a little smaller than that of case 1. Bronchiotoalveolar carcinoma and papillary adenocarcinoma of metastatic origin were considered to be one of the important differential diagnoses with these cytologic features. Histologically, both cases exhibited findings compatible with so-called sclerosing hemangioma of the lung.
