Computed tomography (CT) image and histopathological microphotographs of our case of oral angioleiomyoma. (A) Coronal CT image revealing an oval, enhanced lesion at the right upper buccal region. (B) Hematoxylin and eosin-stained microphotograph showing a nodular mass composed of many vascular vessels with hyperplastic smooth muscle coats mingled with some smooth muscle bundles in the intervascular areas (Original magnification, 20 × ). (C) The Masson's trichrome stain confirmed the smooth muscle coats (red) and the intervascular smooth muscle bundles (red) together with some collagen bundles (blue) in the stromal connective tissues among the thick-walled blood vessels (Original magnification, 10 × ). (D and E) The thickened blood vessel walls were strongly-positive for HHF-35 (D) and moderately-positive for alpha smooth muscle actin (E) (Immunohistochemical stain; original magnification, D and E, 20 × ). (F) The endothelial cells lining the thick-walled blood vessels were positive for CD31 (Immunohistochemical stain; original magnification, 20 × ).
