Solitary fibrous tumor arising from hyperplastic thymus.

One case of a solitary fibrous tumor arising from the hyperplastic thymus is recorded. The patient was a 37-year-old female who presented with an anterior mediastinal mass. Thoracotomy was performed and revealed that the tumor arose on a pedicle from the posteroinferior surface of the enlarged thymus. The pathologic findings were characteristic of a solitary fibrous tumor. This is a very rare neoplasm that occurred in the mediastinum and had evidence of thymus gland in origin.

Video thoracoscopic lung biopsy in diffuse interstitial lung diseases.

The present study examined the use of video thoracoscopic lung biopsy (VTLB) in diffuse interstitial lung disease, in comparison with open lung biopsy (OLB). Twenty and fifteen patients underwent VTLB and OLB, respectively, from 1987 to 1997 at the Central Chest Hospital, Thailand. Data in mean (SD). The mean age was 39 years in both groups. VTLB yielded equivalent size of lung tissues, 4.7 (2.32) cm3, and was as diagnostically useful as OLB. Estimated blood loss, 60 (37) mls, and length of pleural drainage, 2.8 (0.5) days, were comparable in either technique. As OLB had been in practice for decades, it took shorter operative time, 64 (11) mins, than VTLB, 105 (30) mins, (p = 0.005). Both VTLB and OLB approaches were safe and not associated with major postoperative complications.
