Gastric Calcifying Fibrous Tumor Resembling Gastrointestinal Stromal Tumor: A Case Report.

Calcifying fibrous tumor (CFT) is a rare mesenchymal tumor, affecting children and young adults with a predilection for the soft tissue and the abdominal cavity. CFT of the tubular gastrointestinal tract is very rare with less than 20 cases of gastric CFTs reported in English literature. This benign hypocellular fibrosclerotic calcifying lesion can resemble other spindle cell tumors particularly sclerosing gastrointestinal stromal tumor of the stomach. Differentiating between these lesions is particularly important for prognostic and therapeutic purposes. Herein a case of gastric calcifying fibrous tumor incidentally detected during bariatric surgery in a 27-year-old woman is described, with a discussion on its clinicopathological features and differential diagnoses.
