  Figure 2.. Primary pulmonary leiomyoma. A, Hematoxylin and eosin stain: fragment of the tumor showing well-differentiated spindle cells with mature chromatin and rounded edges. Cytoplasm is eosinophilic, and no mitotic figure or necrosis is observed. A–E, Immunohistochemical staining was positive for caldesmon (B), smooth muscle actin (C), and Epstein-Barr encoding region in situ hybridization (D) and negative for human herpesvirus 8 (E). F, Ki-67 is 10%–15%, signifying a low proliferate status and a benign nature.
