Abstract
Pulmonary sclerosing pneumocytoma (PSP) is pathologically classified as an adenoma and behaves in a benign manner. However, some cases of PSP displayed pathologically malignant behavior, such as lymph node metastasis and necrosis. A 64-year-old woman was referred to our hospital complaining of a cough and breathlessness. Histopathological analysis of the resected specimen by left pneumonectomy and lymph node dissection revealed a large PSP measuring 15 × 14 cm in size, with massive necrosis and vascular invasion. This case was the largest ever reported and suggested that clinico-histological presentation of PSP sometimes showed an aggressive phenotype like advanced lung cancer.

Abstract
Sclerosing hemangioma (pneumocytoma) is a rare benign lung tumor with uncertain histogenesis but characteristic histology. Reports of the cytopathology of this tumor are even rarer with only a handful of cases in the literature--many of these incorrectly diagnosed by cytology initially. Herein, we describe a case of sclerosing hemangioma diagnosed prima facie by fine-needle aspiration cytology. A cell block preparation with accompanying immunohistochemistry was instrumental in making the diagnosis. A review of the literature is also presented.

Abstract
A 44-year-old woman underwent surgery for lung cancer. Although preoperative computed tomography did not reveal a tiny nodule, pathological examination of the background lung showed that type II pneumocyte-like tumor cells grew papillary in an area of approximately 2.3 × 1.2 mm. This lesion exhibited hemorrhage, hemosiderosis, calcification, and varying degrees of fibrosis, leading to the diagnosis of sclerosing hemangioma. This is the first reported case of microscopic sclerosing hemangioma undetectable by chest computed tomography.
