  Fig. 2. (A) Histopathologic features of a solitary pulmonary capillary hemangioma (SPCH). Hematoxylin and eosin staining (original magnification, ×200) show alveolar structures with proliferated capillaries and enlarged endothelial cells without cytological atypia. (B–D) Immunohistochemical staining of the SPCH (original magnification, ×200) revealed positivity for thyroid transcription factor-1 (B) in the nuclei of alveolar epithelial cells and for CD31 (C) and CD34 (D) in the cytoplasm of endothelial cells.
