CT and staining observations.. A. Axial CT after contrast administration in portal phase shows large mass that involved peritoneal surface without visceral organ affected. B. Coronal reformatted CT after contrast administration in portal phase demonstrates inframesocolic and paracolic gutters mass with heterogeneous enhancement and few small foci inside (arrows). C. Hematoxylin and eosin stain (20 x) shows glomus body consisting of uniform small, rounded cells with centrally placed round and pleomorphic nuclei. These cells are located around vessels. D. Smooth muscle actin immunostain demonstrating strong cytoplasmic positivity.

This mass showed extensive low-density areas (with CT density values around 25 Hounsfield units [HU]) with interspersed foci of higher attenuation (approximately 50 HU) and some small calcifications (Fig. 1A, B). Immunohistochemically, vimentin, (alpha)-smooth muscle actin, HHF-35 actin and collagen IV were stained intensely (Fig. 1C, D).
