Figure 2. (a) The resected mass. (b, c) Hematoxylin-eosin staining showed sections of bone with mature lamellar bone and bony spicules. Medullary spaces between bony trabeculae revealed irregularly dilated capillaries. Original magnification: b 20; c 200.
A 57-year-old woman with no significant medical history was admitted because of a mass in the right aperture, which was discovered on a chest radiograph (Figure 1(a)). Computed tomography demonstrated a localized mass, measuring 6 cm, along the inner surface of the right 1st rib, with accompanying bone destruction (Figure 1(b), 1(c)). She underwent resection of the 1st rib and apex pulmonis which were adherent to the mass (Figure 2(a)). The pathological findings showed bone sections with mature lamellar bone and bony spicules. Medullary spaces between bony trabeculae contained numerous ectatic blood capillaries (Figure 2(b), 2(c)). The diagnosis was cavernous hemangioma.
