Myofibrosarcoma of the upper jawbones: a clinicopathologic and ultrastructural study of two cases.

abstract：:Lymphoma diagnosis rarely needs electron microscopy (EM), but one area where it can be useful is in the distinction of cytokeratin-positive lymphoma from carcinoma. The authors describe such a case, where difficulties were encountered due to lack of antibody specificity, distinguishing reactive from tumoral cells, and...
