Based on this observation, we compared the keratin, vimentin, and CD-34 expression of 19 SFTs and eight desmoplastic mesotheliomas. Vimentin expression was noted in 18 of 19 SFTs and in seven of eight desmoplastic mesotheliomas. We conclude that CD-34 expression distinguishes SFT from desmoplastic mesothelioma. Additionally, the results of our study support the idea that SFT is not derived from or related to conventional mesothelium. 699 AD - University of Medical Sciences, Guangzhou.
Peritoneal mesothelioma is an infrequently encountered tumor that has a poor prognosis.
Abdominal mass, pain, ascites and weight loss are main manifestations. The epithelial and mixed types are prone to produce ascites. CT scanning is helpful for preoperation diagnosis. In 3 of the 5 patients the tumors have been thoroughly removed, one patient was treated with a partial removal, and one with biopsy only. Two patients have received chemotherapy after operation.
