Nine cases of primary ovarian sarcoma were studied with a panel of 10 antibodies by using the avidin-biotin-complex immunoperoxidase technique. Original diagnoses included five mixed müllerian tumors (MMT) homologous type, two MMT heterologous type, and two pure sarcomas (PS). Cytokeratin
The lysozyme (muramidase) activity was measured in the sera of 84 dogs with neoplastic disease. Neoplasms included 32 lymphomas, 13 primary bone neoplasms, 5 melanomas, 5 thyroid neoplasms, 9 soft tissue sarcomas, 5 mast cell sarcomas, and 15 carcinomas. The sera from 21 healthy dogs served as
A small series of granulocytic sarcomas (GS) or 'chloromas' has been studied by means of conventional histology and immunohistochemistry. The latter was found to be most useful in the diagnosis and characterization of these neoplasms, which are rare in Great Britain. Polytypic antisera to leukocyte
This report describes four malignant tumors originating in infants, (one present at birth), for which a common origin is proposed. The common nature of these tumors was suggested by a remarkable similarity of histologic and ultrastructural features, including the presence of intracellular
Seventeen meningeal tumors were examined for pathology with electron microscopy and immunohistochemistry including glial fibrillary acidic protein (GFAP), S-100 protein, muramidase, and factor VIII. These tumors included seven meningiomas, one hemangiopericytoma, three meningeal sarcomas (1
A case of recurrent Hodgkin's disease of the "sarcomatoid" or "syncytial variant" type was seen that occurred as an extension from the mediastinum to a previously uninvolved extranodal site (breast) and pericardium after treatment of classical nodular sclerosing Hodgkin's disease based in the lymph
Clinical, microscopic, and immunohistochemical characteristics of 17 jaw sarcomas are reported. Histologic subtypes included chondroblastic (five), fibroblastic (five), osteoblastic (three), telangiectatic (one), parosteal (two), and chondrosarcoma (one). Reactivity for all antigenic markers in
Infusion of cycloheximide i.v., an antibiotic known to inhibit synthesis of protein, at a rate of 0.2 mg/kg/hr, reliably caused lysis of fever in 15 chronically febrile patients with Hodgkin's disease who did not have detectable bacterial, fungal, or viral infection. Antipyretic effects were also
Although it is well recognized that granulocytic sarcoma can cause localized lymphadenopathy, widespread nodal involvement by acute myelocytic leukemia (AML), clinically mimicking non-Hodgkin's lymphoma, has only been previously described twice. We report the clinicopathological, immunological, and
