BACKGROUND:A malignant fibrous histiocytoma,recently referred to as an undifferentiated pleomorphic sarcoma (UPS),is very rare in the liver,and only 34 cases of primary hepatic malignant fibrous histiocytoma have been reported in the English literature. METHODS:We report a rare case of a hepatic UPS presenting as a unilocular cystic lesion with respect to histopathologic features,the newly revised diagnostic criteria,and the differential diagnosis. RESULTS:A 60-year-old man presented for evaluation of epigastric pain of 7 months *** computed tomography revealed a hypodense,unilocular cystic mass in the right lobe of the liver,measuring 14.0×11.1 cm.A right lobectomy was ***,the cut surface showed a single,well-circumscribed unilocular cystic tumor mass containing dark red-brown necrotic debris and blood clots, which occupied most of the ***,the tumor consisted of haphazardly arranged mononuclear pleomorphic tumor cells,admixed with abundant osteoclast- like multinucleated giant ***,the tumor cells expressed vimentin *** histopathologic and immunohistochemical findings were compatible with a *** patient is alive and well 41 months after surgery without recurrence. CONCLUSIONS:Clinically,most of the hepatic UPSs are solid *** two cases have presented as multilocular cystic masses.A primary hepatic UPS presenting as a unilocular cyst has never been reported.A UPS should be included in the differential diagnosis of unilocular cystic lesions in the liver.

Protective effect of sulfated polysaccharides from a Celluclast-assisted extract of Hizikia fusiforme against ultraviolet B-induced photoaging in vitro in human keratinocytes and in vivo in zebrafish

引用

Marine Life Science & Technology 2019年第1期1卷 104-111页

作者： Lei Wang Jae Young Oh Hye-Won Yan hyun soo kim You-Jin Jeon Department of Marine Life Sciences Jeju National UniversityJeju CityJeju Self-Governing Province 63243Republic of Korea Marine Science Institute Jeju National UniversityJeju CityJeju Self-Governing Province 63333Republic of Korea

Our previous study evaluated the in vitro and in vivo antioxidant activities of sulfated polysaccharides from a Celluclastassistedextract of Hizikia fusiforme (HFPS). The results indicate that HFPS possesses potent antioxidant activity and suggestthe potential use of HFPS to combat photoaging. In this study, we investigated the ultraviolet (UV) protective effect of HFPSin vitro in keratinocytes (HaCaT cells) and in vivo in zebrafish. The results indicate that HFPS significantly reduced thelevel of intracellular reactive oxygen species (ROS) and improved the viability of UVB-irradiated HaCaT cells. In addition,HFPS remarkably decreased apoptosis formation in UVB-irradiated HaCaT cells in a dose-dependent manner. The in vivotest results also demonstrate that HFPS significantly reduced intracellular ROS levels, cell death, NO production, and lipidperoxidation levels in UVB-irradiated zebrafish in a dose-dependent manner. These results suggest that HFPS possessesstrong in vitro and in vivo UV-protective effects, making it a potential ingredient in the cosmeceutical industry.
