The staples were removed this morning and surgeon is very pleased with the incision. We discussed the pathology report which confirmed OSA. The good news is the lymph node was clean! As were the lungs on day of surgery! I have sme vocabulary to look up but maybe some in the group can translate? Now we need to see the onc again and discuss chemo options.

right humerus mass: the initial tissue sections examined reveal a soft tissue mass composed of a dense sheet of neoplastic cells. These cells have large round, oval or irregular hyper chromatic nuclei with prominent nucleoli and have moderate to abundant amounts of amphophilic cytoplasm. Some neoplastic cells are multinucleated. There are about 30 mitotic figures seen in 10 high power fields examined. This neoplasm extends into bone tissue where there is extensive bone necrosis. In some areas of sheet neoplastic cells exhibit formation of irregular trabeculae ofosteoid matrix material. In other areas there is dense fibrous connective tissue intermixed with neoplastic cells. 

Right axillary lymph node: there is moderate hyperplasia of the lymphoid follicles.
