Solitarni fibrozni tumor SOLITARY FIBROUS TUMORS

927AbstractThe solitary fibrous tumors (STF) are mesen-himal neoplasm. In 2002, WHO classified STF in two groups: benign and malignant. Patohistologi-cal classification is based on three characteristics: more then 4 mitosis in 10 high power fields, pleo-morfismus, and necrosis are malignant signs. Sur-gical en block resection is basic treatment tech-nique. Adjuvant treatment in malignant form, by literature, is not very effective. Surgical treatment is first line of treatment even in case of recidive. Neo-adjuvant treatment suggested for mali-gnant form of this tumor is limited because it is impossible preoperatively to determine definitive patohistological diagnosis. It is due to insufficient amount of tissue example, provided by punction biopsy under CT.In this paper we will show STF operated at 1997 year, and recidive after nine years which was successfully extracted.Key words: The solitary fibrous tumors, thora-cotomy, recidiveSažetakSolitarni fibrozni tumor (SFT) je neoplazma mezenhimalnog porijekla koja se na osnovu WHO (World Health organization) klasifikacije iz 2002 god dijeli na benignu i malignu formu. PHD veri-fikacija se vodi trima karakteristikama- vise od 4 mitoze u 10 vidnih polja, izražena celularnost (pleomorfizam) te nekroze su karakteristike ma-lignih formi.Radikalna hirurska resekcija en block je osnov-ni vid lijecenja.Adjuvantna terapija kod malignih formi ne sma-tra se u literaturi jako uspijesnom-hirurska resekcija na prvom mjestu cak i kod recidiva ovog tumora.Neoadjuvantna terapija koja je bila predložena za maligne forme bila je limitirana nemogucnoscu postavljenjanja preoperativne dijagnoze jer trans-torakalna biopsija pod kontrolom CT-a u vecini slucajeva nije dala dovoljno materijala za adek-vatnu PH verifikaciju.U ovom radu prikazacemo SFT operisan 1997 godine, te recidiv tumora devet godina poslije, koji je uspijesno hirurski uklonjen.Kljucne rijeci: Solitarni fibrozni tumor, tora-kotomija, recidiv
