Purpose To analyze the clinicopathological characteristics of giant cell angioblastoma ( GCAB) presenting primarily in the bone. The differential diagnosis is discussed. Methods The clinical, radiological and histopathological profiles in three cases of bony GCAB were reviewed. Results The tumor occurred in two adult females and one boy. The lesion involved the second vertebrae, left distal femur and 3rd to 5th left metacarpal bones in one case each. Clinically, all three patients presented with bone pain. Two patients were accompanied with restricted mobility. Radiological examination showed bone destruction with involvement of adjacent soft tissue in two cases. Histologically, the tumor was composed of irregular angiomatoid nodules which showed striking plexiform architecture. On high power, the nodules were composed of small vessels surrounded by proliferative oval-to-spindled pericytes which showed concentric aggregation around the vascular channels. The hallmark of the lesion was the presence of multinucleated osteoclast-like giant cells scat-tered within the nodules. By immunohistochemistry, the endothelial cells were positive for CD31 and CD34, whereas the surrounding pericytes were positive for alpha smooth muscle actin and vimentin. CD68 staining highlighted the osteoclast-like giant cells. Conclu-sions GCAB is a distinctive vascular tumor of intermediate malignancy characterize by local aggressiveness. On rare occasions, GCAB may occur in adult patients and manifest as primary bone lesions. Awareness of its characteristic features will help in the distinction from a variety of disease including granulomatous lesions, plexiform fibrous histiocytoma, tufted hemangioma and Kaposiform heman-gioendothelioma.

Objective To establish the cisplatin(DDP)-resistant cell line from human endometrial cancer cell line Ishikawa and to investigate its resistant mechanism to DDP. Methods A resistant endometrial cancer cell line ISH/DDP was established by gradually increasing dose of cisplatin and high-dose stimulation. The resistant index was estimated by 3-(4,5-dimethylthiazol-zyl)-5-(3-carboxymethoxyphenyl-2-(4-sulfophenyl)-2H-tetrazolium,inner salt (MTS) assay. Cell growth curve, doubling time and cell cycle phase distribution were measured; drug-resistant protein of breast cancer resistance protein (BCRP),P-glycoprotein (P-gp) and glutathione-S-transferase-π (GST-π) were examined by immuocytochemistry. Results The DDP-resistant cell line ISH/DDP was established with the resistant index of 3. 77. The proliferation of ISH/DDP got slow, doubling time prolonged, which were 40. 1 hours, while it was 34. 1 hours in Ishikawa (P<0.05); and the cell number of G0/G1 phase [(44. 3 ±5. 7)% and (39. 0 ± 10. 7)% ,P >0. 05] and G2/M phase [(11.9 ±0.7)% and (5. 7 ±2. 4)% ,P <0. 05] decreased, while S-phase [(44. 2 ±6.1)% and (55. 3 ± 8. 4) % , P < 0. 05] increased compared with parent cells. The comprehensive score of the expression of BCRP in ISH/DDP was 16. 3 ± 2. 0, while it was 13.4 ± 1. 5 in Ishikawa (P < 0. 05). The score of the expression of P-gp in ISH/DDP and Ishikawa were 15. 5 ± 1. 2 and 16. 1 ± 1. 0 (P > 0. 05) ,respectively. The score of the expression of GST-π in ISH/DDP and Ishikawa were 15. 2 ± 1. 9 and 14. 9 ± 1.1 (P > 0. 05) . Conclusion ISH/DDP cell line showed a typical resistant phenotype and biological characteristics, which may be accounted for high BCRP expression.
