Fig. 4From: The identification of H3F3A mutation in giant cell tumour of the clivus and the histological diagnostic algorithm of other clival lesions permit the differential diagnosis in this locationClival GCT expresses Tenascin-C and high levels of RANKL. Tenascin-C reactivity in the extracellular matrix and RANKL-positive mononuclear cells in tumour biopsies of patient 1 (left) and patient 2 (right) are shown (20× objective, scale bar 100 μm)Back to article page
