Calcifying Fibrous Tumor Complicated by Empyema.

Calcifying fibrous tumor (CFT) is a rare, benign proliferation of fibroblasts and inflammatory cells that is non-invasive and usually arises in deep tissue structures. Due to its overall paucity, no accurate incidence has been reported yet. We understand this disease via a handful of case studies published in the medical literature, first of them being from 1988.
