Abstract
Solitary fibrous tumors (SFTs) are relatively rare neoplasms that commonly occur in the pleura. The pathological feature of SFTs is a proliferation of spindle-shaped cells in interlacing or storiform fascicles. SFTs appear to derived from pluripotential submesothelial cells, but not the covering mesothelium. SFTs distinctively show diffuse staining for CD34 but lack staining for smooth muscle markers. We herein report a relatively rare case of a 68-year-old male patient without symptoms, who underwent resection for what was considered to be SFT.

Solitary fibrous tumors (SFTs) are relatively rare neoplasms that commonly occur in the pleura
The immunohistochemical findings were compatible with SFT, as the tumor cells were positive for CD34 and bcl-2, whereas alphaSMA, desmin, and S-100 were negative
Careful long-term follow-up is needed for the early detection of growth of the residual tumors, as SFT can develop malignant behavior
