Abstract

We report a rare case of calcifying fibrous tumor of the gastric wall. A 44-year old woman was seen by a health checkup barium study for an abnormal observation indicating a round defect impinging on the lumen suggesting submucosal gastric tumor at the distal anterior wall. Gastroscopy revealed a 3×3cm distal anterior bulge with normal overlying mucosa. Computed tomography (CT) indicated a gastric tumor with calcification projecting from the gastric wall excised in laparoscopic gastric wedge resection. On gross examination, the surgical specimen was a firm gray-white mass 30×26×24mm well-demarcated but unencapsulated. Microscopically it consisted of dense collagenous tissue containing sparse spindle cells, psammomatous calcification, and multifocal lymphoplasmocytic infiltrates. Immunohistochemically, cells were positive for vimentin and negative for CD34, c-kit, α-smooth muscle actin, desmin, S-100, and NSE. The histology was characteristic of a rare calcifying fibrous tumor-only the second, to our knowledge, reported in Japan.
