FIG 1. (continued) E, On gadolinium-enhanced T1-weighted axial image, a homogeneous, enhancing mass is seen at the ciliochoroidal region (open arrow), as is a small amount of nonenhancing subretinal hemorrhage around the posterior pole (arrowhead).
F, Low-magnification photograph of a cut specimen shows a well-circumscribed ciliochoroidal mass involving the whole stroma of the choroids (hematoxylin and eosin staining; magnification x2). C indicates ciliary body; E, subretinal effusion; L, lens; N, optic nerve; and T, tumor.
G and H, Hematoxylin and eosin staining (G) shows spindle cells arranged in intersecting fascicles, and tumor cells that have cigar-shaped nuclei with blunted end (arrowheads). The chromatin pattern is vesicular and mitotic figures are not seen. The tumor cells are positively stained for smooth muscle-specific actin (H).
