Intra-muscular extraskeletal myxoid chondrosarcoma of the thigh: a case report.

Soft tissue sarcomas are mesenchymal tumors that account for about 1% of all malignancies. We retrospectively analyzed a rare case of a painful intra-muscular extraskeletal myxoid chondrosarcoma in the thigh of a 35-year-old man, that had undergone excision. Histological and immunohistochemical analysis of the mass revealed extraskeletal myxoid chondrosarcoma.

Inhibitory effect of miR-145 on RPE cell proliferation.

Objective: This study aims to explore the impact of micro RNA miR-145 on retinal pigment epithelial cell proliferation and apoptosis.
