ABSTRACT
Calcifying fibrous tumor (CFT) is a rare, benign mesenchymal tumor usually affecting children and young adults, and it shows a predilection for the soft tissue and the abdominal cavity. Intrinsic visceral CFT is extremely rare and we present herein the case of a 59-year-old man with an asymptomatic gastric lesion, incidentally detected 1 month before this presentation. Thus, gastric endoscopy revealed a polypoid submucosal mass in the fundus, covered by an erythematous mucosa. The polypoid mass was a 3.9 x 2.7 cm-sized well-defined tumor located in the proper muscle, with extension to the subserosa. The tumor showed characteristic hypocellular sclerosis with coarse collagen, mononuclear inflammatory infiltrates, sparse fibroblastic spindle cells and occasional, psammomatous or dystrophic calcifications. Immunohistochemically, the spindle cells were negative for CD117, CD34, platelet-derived growth factor receptor-alpha, S100, smooth muscle actin, desmin and anaplastic lymphoma kinase.
