Abstract
Estrogen receptors (ER) and progesterone receptors (PR) were evaluated in 173 primary ovarian cancers and in 6 ovarian metastases. In epithelial ovarian carcinomas 63% had ER and 46% PR. Almost all granulosa cell tumours were receptor-positive, while sarcomas, dysgerminomas, and teratomas lacked ER and PR. Both receptors were found less often in tumours of the histological grade I than in those of grade II and III. During the development of metastases and during chemotherapy there was a loss of PR in 27% and 53% of the cases, respectively, while the amount of ER remained more or less constant. In addition to ovarian cancers ER and PR were present in carcinomas of the fallopian tube as well. ER-negative and especially PR-negative tumours seemed to respond better to chemotherapy than receptor-positive carcinomas. The possible significance of ER and PR with regard to the success of an endocrine treatment is discussed.

Abstract
Normal and well differentiated neoplastic canine tissues were immunohistochemically stained for keratin, vimentin and desmin intermediate filament proteins using commercially available monoclonal antibodies. Keratin was detected in 56 of 57 carcinomas, vimentin in 59 of 62 sarcomas and desmin in three of four muscle cell tumors. Most normal and neoplastic tissues expressed only one type of intermediate filament; exceptions were one hemangiosarcoma and one pulmonary carcinoma in which there was coexpression of vimentin and keratin proteins. Since immunohistochemical detection of intermediate filaments has tissue-specific distribution in the majority of well differentiated canine neoplasms, these stains may be useful in the differential diagnosis of anaplastic canine tumors. However, the monoclonal antibodies to cytokeratin which were tested in this study failed to detect intermediate filaments in liver, pancreas and salivary glands which suggests that these antibodies may also be unable to detect epithelial tumors derived from these tissues. In addition, in nine neoplasms, the normal tissues adjacent to neoplastic cells failed to stain for the intermediate filament normally expressed. When this occurs, evaluation of intermediate filament expression is invalid for the determination of tissue of origin of the neoplastic cells.

Abstract
Twenty-three hepatoblastomas of childhood, sixty-two adult hepatocellular carcinomas, and two hepatic sarcomas were examined immunohistochemically with the use of a polyclonal antibody against rat liver fatty acid-binding protein (L-FABP), which cross-reacts to human L-FABP. All the hepatoblastomas and half of the hepatic cell carcinomas contained L-FABP immunoreactive tumour cells, whereas two hepatic sarcomas were negative. The overall frequency of immunostained tumour cells was 43.5 per cent in hepatoblastomas and 18.6 per cent in hepatocellular carcinomas, respectively. Histologically well-differentiated areas contained more numerous immunopositive cells than undifferentiated or immature ones. These results indicate that L-FABP immunoreactivity is a new candidate for a tumour cell marker in hepatic cell malignancies, although its biological role has not been elucidated.

Abstract
Two cell lines, NF and JoN, derived from human ovarian carcinosarcomas, were established in tissue culture and in nude mice. Both lines, growing in monolayers, showed morphologic features of adenocarcinoma cells (NF being aneuploid with a modal number of 53, and JoN being pseudodiploid with a modal number of 44). Intermediate filaments were demonstrated immunohistochemically; the JoN line expressed keratin, but not vimentin or desmin, whereas the NF line expressed vimentin and desmin, but not keratin. Plasminogen activator activity was found in both lines. It is concluded that both of these lines are potentially useful models for studying the diverse characteristics of malignant mixed Müllerian tumors.

Abstract
Increased expression of P-glycoprotein is associated with multidrug resistance (MDR) in many cell lines. Significant levels of P-glycoprotein have been detected in a number of human tumors. The purpose of this study was to determine whether P-glycoprotein expression correlates with both response to chemotherapy and prognosis in soft tissue sarcoma of childhood. In a retrospective study, biopsy samples from 30 cases of rhabdomyosarcoma (RMS) and undifferentiated sarcoma (US) treated at The Hospital for Sick Children in Toronto were analyzed using a semiquantitative immunohistochemical procedure. P-glycoprotein was detected in nine patients, four at diagnosis, and five at subsequent biopsy. All nine patients relapsed after a clinical response (complete [CR] 55%, partial [PR] 45%) to chemotherapy. Twenty of 21 patients with consistently P-glycoprotein-negative tumors received chemotherapy and they all responded clinically (CR 80%, PR 20%). Only one of these 20 patients has relapsed. The probability of relapse-free survival was significantly different (P less than .000000012) in chemotherapy-treated patients whose tumors contained detectable levels of P-glycoprotein (n = 9), compared with those whose tumors contained no detectable P-glycoprotein (n = 20). The overall probability of survival was also significantly different in these two groups (P less than .0000267). Both relapse-free and overall survivals remained statistically different in the two groups of patients when analyzed by the log-rank method, after adjustment for differences in stages and sites. The incidence of other adverse prognostic factors in the two groups, for example, younger and older ages, low pretreatment lymphocyte counts, large tumors, and unfavorable histology were not significantly different. Thus, detectable P-glycoprotein appears to be an important adverse prognostic factor in children with soft tissue sarcoma, and consistent absence of the protein is associated with a favorable prognosis.

Abstract
Twelve cases of alveolar soft part sarcoma (ASPS) were reviewed. Seven of them arose primarily in the lower extremities, three in the head and neck region, and two in other parts. ASPSs in the head and neck region occurred in children before 10 years of age, whereas ASPSs in the other regions occurred in rather older patients. Moreover, ASPSs of the head and neck were relatively small in size, and were diagnosed earlier than those in other regions. Histologically, six cases (including all the head and neck cases) contained considerable area of small and indistinct alveolar structures. Four cases showed remarkable cellular pleomorphism. Immunohistochemical demonstration of vimentin, desmin, the beta-subunit of enolase and the MM isozyme of creatine kinase, together with the absence of immunoreactive cytokeratin, supported the myogenic nature of this rare tumor. A small number of S-100 protein-positive tumor cells were also observed. Follow-up data for these cases disclosed that the tumors containing considerable area of small alveoli and uniform small tumor cells formed distant metastases at an early stage.

Abstract
We studied an unusual sarcoma with morphologic features diagnostic of epithelioid sarcoma by conventional light microscopy, transmission electron microscopy, and immunohistochemistry. The primary tumor, which was located in the deep soft tissues of the buttock of a 32-year-old woman, and its metastases to lymph nodes, liver, and lung were available for investigation. The histomorphological and ultrastructural appearance of the primary tumor and its metastatic deposits were typical of epithelioid sarcoma. Immunohistochemistry revealed a strong and uniform reactivity for vimentin in both the primary tumor and its metastases. In contrast, a marked cytoskeletal heterogeneity became evident for cytokeratins and neurofilaments, which were observed exclusively in lymph node metastasis. To our knowledge, the observation of neurofilaments in epithelioid sarcoma has not previously been reported.

Abstract
The immunohistochemical expression of cytoskeletal proteins in alveolar soft part sarcoma (ASPS) was studied by light and electron microscopy. Of the five cases examined by the avidinbiotin-peroxidase complex method, variable numbers of immunoreactive cells for desmin were found in three, for vimentin in two, for muscle-specific actins in three, and for alpha-smooth muscle actin in four. Immunoelectron microscopic study demonstrated that desmin and vimentin were localized on whorled bundles of intermediate filaments in the perinuclear cytoplasm. In addition, a few dispersed intermediate filaments became evident in specimens treated with saponin and fixed with tannic acid. These immunohistochemical results indicate that a few tumor cells of ASPS may express some properties of the cytoskeleton of smooth muscle cells in addition to those of skeletal muscle cells. Considering the discrepancies reported in the actin isoforms demonstrated in myogenic tumors, we conclude that ASPS is probably a peculiar, primitive myogenic tumor that does not show any distinctive features of rhabdomyogenic or leiomyogenic differentiation.

Abstract
Elevated activities of cysteine proteinases such as cathepsins B and L and cancer procoagulant have been linked to tumor malignancy. In the present study we examined the hypothesis that these elevated activities could be due to impaired regulation by the endogenous low molecular mass cysteine proteinase inhibitors (cystatins). Inhibitors from human sarcoma were compared to those from human liver, a normal tissue in which the inhibitors had been characterized previously. An extract of cystatins from sarcoma was less effective against papain and cathepsin B (liver or tumor) than was an extract from liver. This reduced inhibitory capacity in sarcoma was not due to a reduction in either the concentrations or specific activities of the cystatins or an absence of any family or isoform of cystatins. We purified two members of the cystatin superfamily (stefin A and stefin B) to homogeneity and determined their individual inhibitory properties. Stefins B from liver and sarcoma exhibited comparable inhibition of papain and cathepsin B. In contrast, stefin A from sarcoma exhibited a reduced ability to inhibit papain, human liver cathepsins B, H and L and human and murine tumor cathepsin B. The Ki for inhibition of liver cathepsin B by sarcoma stefin A was 10-fold higher than that for inhibition of liver cathepsin B by liver stefin A, reflecting a reduction in the rate constant for association and an increase in the rate constant for dissociation. Cancer is now the third pathologic condition reported to be associated with alterations in cystatins, the other two being amyloidosis and muscular dystrophy.

Abstract
The expression of human nerve growth factor (NGF) receptor in tumors and normal tissue was investigated with the use of a monoclonal antibody recently developed against that protein. This antibody, NGFR5, reacted strongly with 100% of 25 nerve sheath tumors. Eight of nine pheochromocytomas and three of three paragangliomas also had positive results, but the immunoreactivity was restricted to the sustentacular cell population. Within cells of melanocytic lineage, there was no immunostaining of melanocytes in normal epidermis, whereas 13 of 14 benign nevi had positive results, primarily involving spindled nevocytic structures within the dermis. NGF receptor was scarcely expressed in human melanoma; 9 of 19 melanomas had positive results, but immunoreactivity was generally restricted to rare cells within the larger tumor cell population. Among nonneurogenic mesenchymal tumors, results were generally negative: 0 of 5 chondrosarcomas, 0 of 6 malignant fibrous histiocytomas, 0 of 3 meningiomas, and 1 of 8 leiomyosarcomas were immunoreactive. Carcinomas were variable in immunoreactivity: 12 of 16 squamous cell carcinomas had positive results, whereas adenocarcinomas demonstrated focal, basal epithelial immunoreactivity and neuroendocrine tumors generally had negative results. Among normal tissues, in addition to expected neural immunostaining, NGFR 5 reacted positively with several nonneural cell types, including lymphoidal follicular dendritic cells, myoepithelial cells, vascular adventitia, and basal epithelium of oral mucosa and hair follicles. Antibodies to NGF receptor may play a role in the identification of benign and malignant soft tissue lesions.

Abstract
Four cases of esophageal polypoid tumors composed of squamous cell carcinoma and spindle cell sarcomatous components were investigated. Squamous cell carcinoma was consistently present in the base of the polypoid lesions in all four cases and was also intermingled with spindle-shaped sarcomatous cells in two cases. Metastases in the lymph nodes were observed in two cases: one was squamous cell carcinoma with a sarcomatous component and the other consisted of a pure sarcomatous component. All tumors involved at least the muscularis mucosae. In the sarcomatous region, the tumor was composed of highly anaplastic cells with or without forming interlacing fascicles. Pleomorphism was marked and bizarre giant cell forms were frequent. Mitoses were frequently present. Immunohistochemical study revealed that the anaplastic cells in the sarcomatous component in all cases were immunoreactive to desmin, muscle actin, vimentin, and alpha 1-antichymotrypsin, but were negative for cytokeratin, even in the metastatic tumors of the lymph nodes. The immunohistochemical results favor myogenic differentiation of the anaplastic cells, and these tumors were considered to be true carcinosarcomas composed of squamous cell carcinoma and leiomyosarcoma.

Abstract
Epithelioid sarcoma (ES) and malignant rhabdoid tumor (MRT) have heretofore been regarded as two separate clinicopathologic entities. However, they have some histologic similarities, and both represent histogenetic and phenotypic enigmas. This study reports the pathologic and immunohistochemical findings of four vulvar neoplasms occurring in young women that represented diagnostic dilemmas because of their similarity to both ES and MRT. Only one case had the classic histologic features of ES, whereas, in our opinion, the other three cases fulfilled the histologic criteria of MRT, despite the fact that two of the three cases were reported earlier as examples of ES. Neither electron microscopy nor immunohistochemistry has been found to be helpful in separating ES from MRT, mainly because they share several ultrastructural and immunophenotypic features. The behavior of these vulvar tumors--ours and the few published examples of ES--is generally aggressive, more in keeping with MRT than classic ES. We believe that some, if not most, putative ES of the vulva are in fact MRT, a neoplasm with an unfavorable prognosis.

Abstract
The cytoplasmic filament composition of two pure high-grade endometrial stromal sarcomas and five pure endometrial rhabdomyosarcomas was studied using the immunoperoxidase avidin-biotin method. Ultrastructural correlates were performed on the same tissues. While four of the seven tumors presented as high-grade undifferentiated neoplasms, they were readily categorized on the basis of immunocytochemical findings in which the five rhabdomyosarcomas were positive for muscle-specific actin (HHF 35) and the two stromal sarcomas were positive for vimentin only. Ultrastructure on the HHF 35-positive cases showed the presence of thick filaments and Z-band material, whereas the other tumors showed no cytoplasmic differentiation. Muscle-type actin differs stromal cells, and is useful when used in conjunction with a panel of antibodies in the categorization of undifferentiated endometrial sarcomas.

Abstract
Glycoproteins IIb and IIIa, a heterodimer complex, play a vital role in blood platelet aggregation and are members of a wide family of membrane receptors known as integrins or cytoadhesins. Cellular interaction to extracellular matrix (ECM) adhesive proteins is mediated by integrins. Certain tumor cells are known to interact with ECM and blood platelets in the process of metastasis. However, it is not known if tumor cells, compared with their normal counterparts, acquire IIb-IIIa-like receptors to help them in their metastatic spread. In this study, monoclonal antibodies directed against the IIb-IIIa platelet glycoprotein complex were used on frozen biopsies of normal and various tumor tissues to detect the presence of these integrins. These studies demonstrate the presence of IIb-IIIa-like glycoproteins on the cells of metastatic malignant melanoma but not on benign melanocytes and rarely on other tumors. The presence of integrins on melanomas may help explain their propensity for frequent metastasis.

Abstract
The clinicopathologic, ultrastructural and immunohistochemical features of eleven cases of clear cell sarcoma are described. There were 6 males and 5 females with an average age of thirty-six (10-59 years). Tumors were found arising from the tendons, aponeuroses and fascial structures with a predilection for the lower and upper extremities. Follow-up data was available in 8 patients. Five of them are alive. Nevertheless, 3 of the five showed evidence of recurrence or metastasis. The other 3 patients died of tumor with metastasis. Microscopically, the tumors were composed of short fascicles of fusiform cells with a clear to eosinophilic cytoplasm and vesicular nuclei with prominent nucleoli. Melanin was demonstrated in 5 cases and S-100 was known present focally in all cases, but no positive keratin staining was obtained. Electron microscopic studies revealed cell attachments and mature melanosomes. The exact histogenesis remains obscure, but our ultrastructural and immunohistochemical findings support the idea of neural crest origin of this tumor.

Abstract
We describe a case of sarcomatous tumor of the chest wall with differentiation toward bone and cartilage that was observed in an asbestos-exposed worker. Although the mesothelial nature of the tumor was at first considered, it was not proven. Later, the tumor was shown to be a mesothelioma using a panel of pertinent antibodies that included a recently described anti-mesothelial cell marker. In addition, asbestos bodies were found in association with the sarcoma cells. Our findings indicate that whenever physicians encounter any type of primary sarcomatoid tumor involving serous membranes, the possibility of malignant mesothelioma should be regarded a priori.

Abstract
Fourteen alveolar soft part sarcomas were studied using electron microscopic analysis and a battery of immunocytochemical procedures in order to critically assess the extent to which these methods could explain the histogenesis of the tumor. All the tumors were stained with antibodies against keratin, vimentin, S-100 protein, Leu-7, neuron-specific enolase, desmin, muscle-specific actin, myoglobin, smooth muscle myosin, and fast and slow myosins. Eight tumors stained for vimentin, eight for desmin, eight for neuron-specific enolase, two for muscle-specific actin, and one for fast myosin. No reactivity was detected with the other antibodies. Electron microscopic study showed a consistent pattern of fine structure and clarified the mode of formation of the distinctive cytoplasmic crystals which were detected in all 14 tumors. Intermediate filaments were sparse and specific myofilaments were not detected. Alveolar soft part sarcoma has a myogenic phenotype and the cells show skeletal muscle differentiation but do not closely resemble any known prototypic normal cell.

Abstract
Proliferative activity of soft tissue sarcomas (STS) in 34 cases was estimated by immunohistochemical procedures (avidin-biotin complex [ABC] method) with monoclonal antibody Ki-67 which reacts with a nuclear antigen expressed in all phases of cell cycle except G0. In 20 of 34 cases (59%), varying numbers of Ki-67-positive tumor cells were detected with a range from 5 to 382 per 10 high power fields (HPF) (mean 57.2/10 HPF). Ki-67 index (the number of Ki-67-positive tumor cells/10 HPF) positively correlated with mitotic count (r = 0.428, P less than 0.02), cellularity (r = 0.447, P less than 0.01), and histologic grade (r = 0.473, P less than 0.01). The Ki-67 low index group (less than 50/10 HPF) showed more favorable prognosis than the high index group (more than 50/10 HPF) (P less than 0.005). Three cases with low mitotic count and unfavorable prognosis were proved to be the Ki-67 high index group (142-382/10 HPF). These results indicated that reactivity of tumor cells for Ki-67 is a useful prognostic marker in the patients with STS, and might be used as one of the histologic factors for the grading of STS.

Abstract
Two cases of low-grade endometrial stromal sarcoma (ESS) presenting as cystic pulmonary metastases are reported. Both lung lesions were initially thought to represent examples of so-called mesenchymal cystic hamartoma. A diligent search of the past medical records in the first case revealed that a primary low-grade ESS of the uterus had been resected 27 years earlier. In the second case, a uterine tumor was seen by computed tomography scan and subsequent pathologic examination of the hysterectomy specimen established the presence of a low-grade ESS. Peritoneal metastases, present in both cases, also presented diagnostic problems until the uterine primaries were recognized. Immunoreactivity for desmin was detected in all primary and metastatic tumor sites examined. We conclude that ESS should be included among the desmin-positive spindle cell sarcomas and that metastatic ESS should be included in the differential diagnosis of "benign" mesenchymal cystic hamartoma of the lung.

Abstract
The estrogen receptor content, determined immunohistochemically by staining with monoclonal antibodies, was studied in seven consecutive cases of endometrial stromal sarcoma. In addition, the mitotic rate and immunohistochemical patterns (vimentin, desmin, actin, cytokeratins) were determined. Five of seven cases contained estrogen receptors, three low-grade (fewer than 10 mitoses/10 high-power fields [hpf]) and two high-grade (10 or more mitoses/10 hpf), the latter having a relatively low mitotic rate. The two negative cases were high-grade with a very high number of mitoses. Tumor cells were positive only to vimentin. Based on these results, we postulate that estrogen receptors are undetectable only in highly proliferating neoplasms. Thus, immunohistochemically determined estrogen receptor levels may indicate the aggressiveness of endometrial stromal sarcoma, and might be a guideline in selecting patients for hormonal therapy. The presence of positive immunostaining to vimentin confirms the mesenchymal origin of endometrial stromal sarcoma.

Abstract
In order to analyze the mucoid substance in the epithelial component of synovial sarcoma, electron microscopic and cytochemical studies were made on three of these neoplasms. The mucoid substances in the glandular lumen were intensely stained with ruthenium red (RR), appearing as granular, fibrillar and amorphous structures. RR staining of proteoglycans was diminished after treatment with chondroitinase AC or ABC, and was partially diminished by exposure to streptomyces hyaluronidase. Trypsin treatment did not affect RR staining of proteoglycans in the lumen. On thin sections stained with periodic acid-thiocarbo-hydrazide-silver proteinate (PA-TCH-SP), deposits of reaction product were observed on the mucoid substances within the lumen, and were localized in the Golgi complex, including the rough endoplasmic reticulum, small vesicle and lysosome-like dense body. Trypsin digestion decreased the stain intensity of PA-TCH-SP. These results indicate that the lumen of the gland-like component contains glycoproteins as well as proteoglycans mainly consisting of chondroitin sulfate and hyaluronic acid, and suggest that GERL (Novikoff) is closely related to production, storage and transport of glycoproteins in the cytoplasm of tumor cells.

Abstract
Clear cell sarcoma (CCS) is an uncommon, clinicopathologically distinct neoplasm that typically arises in association with tendons and aponeuroses. It shares several histologic and ultrastructural features with malignant melanoma. Clear cell sarcoma occasionally may be confused with other tumors of soft tissue that have a predominantly epithelioid appearance, including epithelioid leiomyosarcoma, epithelioid neurofibrosarcoma, synovial sarcoma, and epithelioid sarcoma. To assess the potential contribution of immunohistochemistry to this differential diagnosis, a panel of immunostains was applied to examples of each of these neoplasms. All six CCSs contained vimentin, and five were reactive with the melanoma-specific monoclonal antibody HMB-45. In addition, five CCSs expressed neuron-specific enolase, four cases displayed S100 protein, and four examples contained LN3 antigen. Synaptophysin and Leu-7 antigen were present in one case each. Cytokeratin, epithelial membrane antigen, carcinoembryonic antigen, desmin, muscle-specific actin, and leukocyte common antigen were invariably absent. No other primary epithelioid neoplasm of soft tissue reacted with HMB-45. Clear cell sarcoma could be separated from epithelioid leiomyosarcoma by the presence of desmin and muscle-specific actin in the latter neoplasm. Similarly, both synovial sarcoma and epithelioid sarcoma differed from CCS by their expression of cytokeratin and epithelial membrane antigen. Clear cell sarcoma and malignant melanoma were immunohistochemically indistinguishable, supporting the concept that they share a common pattern of differentiation.

Abstract
Crystalline specimens imaged in the electron microscope are analysed using digital processing. Some principles of structural analysis using the method of Fourier decomposition are discussed. Complementary techniques, such as enhancement by gradient and Laplacian operators, have been found useful in analysing electron micrographs. The application of these techniques to some problems in Materials Science and Biology are reviewed. By selecting and phase-correcting spots in the computed diffraction pattern, it was possible to localize atoms, molecules, and their defective arrangement in evaporated gold, sputter-deposited tungsten films, and single crystals of cadmium selenide. Digital processing based on the theory of helical diffraction was used to explore the three-dimensional arrangement of molecules in cellular components of alveolar soft part sarcoma, Hirano bodies, and neurofibrillar tangles in the human brain.

Abstract
Primary sarcomas of the aorta are rare; fewer than 30 cases have been reported. Among these, the majority are intraluminal and apparently intimal in origin. Extensive histochemical and electron-microscopic evaluation of these tumors has not previously been performed. We present a case of aortic intimal sarcoma in a 70-year-old man whose resected aorta showed multifocal, intimal tumor that appeared on light microscopy to be undifferentiated sarcoma. Electron microscopy was not helpful; however, immunohistochemical studies confirmed the endothelial nature of this neoplasm. The multifocal pattern of the tumor and the presence of intervening, atypical, proliferative endothelial cells suggests that endothelial dysplasia may have been a precursor lesion.

Abstract
Two cases of alveolar soft part sarcoma have been studied immunocytochemically using antisera against epithelial membrane antigen, lysozyme, keratins, S-100 protein, desmin, vimentin, fetal myosin, slow myosin, alpha-skeletal muscle actin, alpha-smooth muscle actin and myoglobin. The neoplastic cells were negative with all antisera employed with the exception of the alpha-skeletal muscle actin antiserum which stained the cytoplasm of numerous neoplastic elements, including the crystalloid rods, typical cytoplasmic inclusions of these tumours. It is suggested that the presence of this protein indicates rhabdomyoblastic differentiation of these tumours.

Abstract
The existence of a tumor necrosis factor (TNF) receptor on KYM human myosarcoma cells was elucidated by Scatchard plot and cross-linking analysis. The average number of specific binding sites per cell was 15,300 and the apparent dissociation constant Kd was 4.0 X 10(-10) M. The estimated relative molecular mass of a TNF receptor on KYM cell was approximately 95,000.

Abstract
Normal differentiation and malignant transformation of human cells are characterized by specific changes in surface antigen phenotype. In the present study, we have defined six cell-surface antigens of human sarcomas and normal mesenchymal cells, by using mixed hemadsorption assays and immunochemical methods for the analysis of cultured cells and immunohistochemical staining for the analysis of normal tissues and greater than 200 tumor specimens. Differential patterns of F19 (Mr, 120,000/95,000 glycoprotein), F24 (Mr, 95,000 glycoprotein), G171 (Mr, 75,000 glycoprotein), G253 (Mr, 90,000 glycoprotein), S5 (Mr, 120,000 glycoprotein), and Thy-1 (Mr, 25,000 glycoprotein) antigen expression were found to characterize (i) subsets of cultured sarcoma cell lines, (ii) cultured fibroblasts derived from various organs, (iii) normal resting and activated mesenchymal tissues, and (iv) sarcoma and nonmesenchymal tumor tissues. These results provide a basic surface antigenic map for cultured mesenchymal cells and mesenchymal tissues and permit the classification of human sarcomas according to their antigenic phenotypes.

Abstract
The presence of alpha 2-macroglobulin (alpha 2M) was detected with the avidin-biotin technique in more than 20-yr-old paraffin blocks from human sarcomas. alpha 2M was found mainly in the cytoplasm of the tumor cells, and almost all tumor cells were positive. This serum glycoprotein, which is a major plasma proteinase inhibitor with a wide specificity, was also shown to be synthesized and secreted by all three cell lines derived from primary sarcomas but was not detected in cultures of the autologous skin fibroblasts. For the detection of alpha 2M in situ and in vitro an antiserum to tumor-associated alpha 2-macroglobulin was used.

Abstract
Two monoclonal antibodies (LN-4, LN-5) reactive to human macrophages in B5 formalin-fixed, paraffin-embedded tissue sections have been produced by using deparaffinized cell extracts of peripheral blood mononuclear cells. Both monoclonal antibodies were initially identified on paraffin-embedded sections of hyperplastic lymph nodes by using the immunoperoxidase staining procedure. Specificity screens on normal human tissues show that LN-4 and LN-5 stain the cytoplasm of macrophages and histiocytes in hematopoietic organs including Kupffer's cells of the liver and Langerhans' cells of the skin. LN-4 also showed strong positivity with acini of the stomach, whereas LN-5 was positive with mantle zone B lymphocytes of the lymph node and spleen, spermatogonia, and chief cells of the stomach. Both antibodies were strongly reactive with cases of true histiocytic lymphoma but, except for infiltrating macrophages, were entirely negative in Hodgkin's disease and non-Hodgkin's lymphomas. In all cases of nodular sclerosis Hodgkin's disease, LN-4 was positive in macrophagelike cells present in the collagen bands surrounding the Hodgkin's lesions. Both monoclonal antibodies were also positive in macrophages and histiocytes present in a variety of benign lymphoid lesions including persistent generalized lymphadenopathy, Gaucher's disease, sinus histiocytosis, and dermatopathic lymphadenopathy. Because of their specificity for human macrophages, and their ability to stain B5-fixed, paraffin-embedded tissues, LN-4 and LN-5 are important new reagents for the diagnosis and classification of malignant and benign histiocytic lesions.

Abstract
The collective expression of five antigens produced in immature or mature myelin-producing glia was evaluated in nerve sheath tumors and spindle cell sarcomas with histologic features of schwannomas. Myelin-associated glycoprotein (Leu-7), myelin basic-protein (MBP), S100-protein, and, in most cases, glial-fibrillary acidic-protein (GFAP) and HLA-DR/Ia (LN3) immunoreactivity were evaluated immunohistochemically using commercially available antibodies on 53 benign nerve sheath tumors and 12 sarcomas. Leu-7 immunoreactivity was detected by a monoclonal antibody in 12 of 16 schwannomas, 12 of 20 neurofibromas, and 17 of 17 traumatic neuromas. No Leu-7 positivity was seen in the sarcomas. Distinct heavy MBP immunoreactivity, assessed using polyclonal antibodies, was identified only in all 17 traumatic neuromas. Extensive S100-protein positivity was seen in 15 of 16 schwannomas, 17 of 20 neurofibromas, and 17 of 17 traumatic neuromas. Extensive LN3 immunoreactivity was seen in Schwann cells of 50% of the nerve sheath tumors analyzed; however, it was also present in associated interdigitating reticulum cells; GFAP immunoreactivity was not detected. These data suggest that Leu-7 is an important marker of Schwann cell neoplasms, although it is not superior to S100 protein. Moreover, combined immunohistochemical evaluation of potential Schwann cell markers including Leu-7, MBP, GFAP, and LN3 using commercially available antibodies offers no advantage over analysis of S100-protein immunoreactivity alone.

Abstract
Eight primary carcinomas of the lung with a prominent spindle-cell sarcomatoid component were studied by immunocytochemical staining and electron microscopy. The eight tumors were indistinguishable by conventional light microscopy, with the exception of one unusual neoplasm that followed multiple pathways of differentiation with elements of squamous cell carcinoma, rhabdomyosarcoma, chondrosarcoma, and an undifferentiated spindle-cell population. Reticulin fiber production by individual spindle cells and a sharp demarcation of the carcinomatous and sarcomatoid domains by light microscopy were not useful differentiating features. Three of the eight tumors exhibited keratin expression in both the carcinomatous and spindle-cell components. Both immunocytochemical and electron microscopic analyses were required to detect epithelial differentiation, as in one case keratin was identified only by immunocytochemical staining and in another only by ultrastructural examination. Epithelial differentiation was undetectable in the sarcomatoid component of five tumors, and in one case immunoreactive myoglobin was identified in spindle cells; skeletal muscle differentiation was confirmed ultrastructurally. We propose that pulmonary carcinomas exhibiting evidence of epithelial differentiation in a sarcomatoid component be termed spindle-cell carcinomas and that those biphasic tumors exhibiting mesenchymal differentiation into specific tissues, such as neoplastic bone, cartilage, or striated muscle, or lacking epithelial differentiation by light microscopy, immunocytochemistry, and electron microscopy be classified as carcinosarcomas. This distinction may ultimately be unnecessary, because these two tumors may represent different points along a morphologic and biologic continuum.

Abstract
The type, differentiation and histogenesis of the tumor cells of alveolar soft part sarcoma (ASPS) have been analyzed in a series of ten cases by a light-microscopic, ultrastructural, immunohistochemical and cytologic investigation and quantitative DNA analysis. Four tumors deviated from ordinary ASPS: three were wholly or partly of the so-called pleomorphic variant of ASPS and a fourth tumor showed calcifications of the psammoma body type. The ultrastructural findings and immunohistochemical demonstration of desmin supported the hypothesis of a rhabdomyomatous differentiation and gave no support to epithelial (negative immunoreactions for cytokeratins, epithelial membrane antigen, HMFG-1 and -2, tissue polypeptide antigen (TPA] or neuroectodermal (negative for S-100 protein, glial fibrillary acidic protein, neurofilaments) differentiation. The negative immunoreactions for vimentin and myoglobin and the positive reaction for neuron specific enolase (NSE) do not exclude a rhabdomyomatous differentiation since in rhabdomyosarcomas the undifferentiated rhabdomyoblasts generally contain vimentin and the differentiated tumor cells contain myoglobin and rhabdomyosarcoma has previously been reported as being positive for NSE. The production of external lamina material peripherally in the tumor cell nests and around vessels in the vascular septa was demonstrated both ultrastructurally and by immunohistochemistry using antibodies against collagen IV and laminin. The cytologic appearance in smears obtained by fine-needle aspiration from a case of the pleomorphic variant showed some resemblance to that of a carcinoma. The seven tumors with an ordinary cell appearance were found to show a diploid DNA-distribution at a quantitative analysis performed on paraffin sections, while the three tumors wholly or partly of the pleomorphic type showed an additional tetraploid peak.

Abstract
The clinicopathologic picture of a case of so-called 'sarcoglioma' is reported. This tumor is characterized by a core of sarcomatous tissue, surrounded by an area of gradual transition from reactive to neoplastic glial cells; it occurs in children or in young adults and is very rare in comparison with the secondary sarcoma deriving from the vascular component of a glioblastoma (so-called 'gliosarcoma'). The clinical and laboratory features and the pathology of this case are discussed in detail.

Abstract
Overexpression of an immunologically conserved, cell-surface glycoprotein (P-glycoprotein) is consistently associated with multidrug resistance in cell lines in vitro. A preliminary survey of specimens from 12 solid tumor types in our laboratories indicates significant overexpression of P-glycoprotein in some sarcomas. When tested by immunoblotting with monoclonal antibodies directed against P-glycoprotein; tumors from six of 25 sarcoma patients displayed elevated levels of P-glycoprotein. Three of the sarcoma patients exhibiting P-glycoprotein had not previously been exposed to chemotherapy, implying that overexpression of this marker and possible concomitant multidrug resistance may not depend only on selection during prior drug treatments. The P-glycoprotein overexpression in the sarcoma specimens is evidence for the presence of multidrug resistant cells in these tumors; thus, our data suggest that this mode of resistance may have clinical significance in sarcoma patients.

Abstract
A 26-year-old woman was operated on for a bulky tumor in the sacral region; she died of massive local tumor recurrence and pulmonary metastases 3 months later. Most of the original tumor showed a highly cellular spindle-cell sarcoma compatible with a fibrosarcoma of a high grade of malignancy. In a few small areas of the tumor, a chordoma-like pattern surrounded by growth of spindle-cell sarcoma was found. The spindle-cell component exhibited vimentin positivity in all tumor cells, but many cells were also cytokeratin-positive. The chordoma-like areas showed cytokeratin in all tumor cells. The chordoma-like areas, but not the spindle-cell areas also were positive for epithelial membrane antigen and S-100 protein. This case indicates that the sarcomatous change associated with chordoma may contain keratins as a sign of epithelial differentiation, and may thus represent sarcomatous transformation of chordoma cells, rather than a coincidental soft-tissue sarcoma or collision tumor.

Abstract
A study of immunocytochemical staining for apolipoprotein B (apo B) in 52 human sarcomas and eight benign soft-tissue tumors is described. A peroxidase-antiperoxidase technique was employed using a rabbit anti-apo B antiserum. All 27 liposarcomas examined were positive for apo B, and 23 of these tumors showed at least 2-plus staining on a scale of 0 to 3 plus. Of the ten myxoid liposarcomas within this group, seven showed 2-plus or 3-plus staining, while the other three stained 1 plus. By contrast, 11 of 13 malignant fibrous histiocytomas were negative for apo B; the remainder showed 1-plus staining. Myxoid areas present in three of these cases were negative for apo B. Five of seven rhabdomyosarcomas stained at least 2 plus for apo B. Both benign and malignant peripheral nerve sheath tumors showed no consistent pattern of staining. We conclude that apo B immunocytochemical staining tends to be high in tumors whose normal tissue counterparts exhibit relatively large numbers of low-density lipoprotein receptors. Furthermore, immunoperoxidase staining for apo B should be a useful adjunct in the evaluation of soft-tissue sarcomas, particularly in cases with myxoid differentiation.

Abstract
Using an avidin-biotin immunoperoxidase technic, the authors studied 29 anaplastic thyroid tumors (ATTs) to determine the frequency of hormonal (thyroglobulin--TG; calcitonin--CT), epithelial (epithelial membrane antigen, monoclonal keratin), or sarcoma (desmin; alpha-1-antichymotrypsin--ACT; vimentin) markers. Their results indicate that 27% of ATTs stain for TG and none for CT. Fifty-five percent showed epithelial markers, 48% marked for ACT, and 47% for vimentin. Coexpression of keratin and vimentin was found in 39% of cases tested. The expression of the tested antigens did not correlate significantly with histologic pattern (epithelial vs. "sarcomatous"). Of note is the fact that 30% of the ATTs the authors tested expressed none of the markers they examined, indicating total lack of differentiation.

Abstract
The immunohistochemical findings in 14 epithelioid sarcomas, neoplasms of uncertain histogenesis, indicate that they react with antibodies against cytokeratin, epithelial membrane antigen, and vimentin. All cases were nonreactive for leukocyte common antigen, myoglobin, and Factor VIII-related antigen. These results point to the fact that epithelioid sarcoma expresses phenotypic characteristics more often associated with epithelioid neoplasms, rather than the mesenchymal profile of most soft tissue sarcomas. One explanation for this observation is that epithelioid sarcoma is in fact a carcinoma originating in the deep soft tissues. On the other hand, the pluripotential mesoderm has a known embryonic capacity to differentiate into epithelium and, therefore, it is plausible that epithelioid sarcoma is a mesenchymally derived neoplasm. Aside from histogenetic considerations, epithelioid sarcoma may be confused with a number of other neoplastic and granulomatous processes. Differential immunohistochemical stains are useful in selected instances wherein light and electron microscopic findings are diagnostically equivocal.

Abstract
Biochemical and blood perfusion changes in a mouse tumor system (MDAH MCaIV) were studied relative to normal tissues under conditions of normal blood flow and clamped blood supply. Further studies were performed during tumor growth and after local X irradiation. The biochemical profiles of three untreated human soft tissue sarcomas were also investigated. Animal tumors were irradiated in situ with either a single or fractionated regime to total doses of 20 or 49 Gy. Assays of lactate, pyruvate, AMP, ADP, and ATP were made on freeze-clamped tissue following authentic or sham treatments. Blood perfusion to tumors treated in the same way was measured using iv injection of 201Tl. The human tumors were found to have a lower lactate to pyruvate ratio (L/P) than the MCaIV tumors; their ATP levels were also lower. L/P was much higher in the MCaIV tumors than in normal liver, kidney, and muscle in the mouse. Occlusion of the blood supplies of the normal kidney and the MCaIV tumor caused an increase in the lactate and L/P levels in both cases. However, whereas the ATP level in the kidney fell, the level in the tumor was maintained. There was some evidence that the adenine nucleotides were not in equilibrium via the adenyl kinase catalyzed reaction. In addition, tumors were found to contain the enzyme creatine kinase. These results suggest that energy charge calculations cannot be computed in a meaningful manner because the creatine kinase catalyzed phosphorylation of ADP would maintain a higher than normal ATP level. Lactate and L/P ratio was found to increase during tumor growth and decrease following X irradiation. The total adenine nucleotides (AMP + ADP + ATP) exhibited a trend toward lower values with increasing tumor size. There was no significant change in total adenine nucleotides after a single 20-Gy dose; however, fractionated radiation caused some fall in total nucleotides. It is concluded that, in this tumor system, lactate level is a sensitive index of radiation-induced biochemical changes which are likely to reflect changes in tumor oxygenation.

Abstract
A cell line (RM-HS1) derived from a human epithelioid sarcoma was established in tissue culture. Ultrastructurally, the cells show features of those found within the primary tumor. A mixed mesenchymal-epithelial phenotype, defined by reactivity with antibodies to epithelial membrane antigen and to vimentin and keratin intermediate filaments, was found in the tumor, and a similar phenotype persisted in the cultured cells. Cytogenetic analysis revealed a mode of 66 chromosomes. With the use of a variety of banding techniques together with in situ hybridization of a 3H-labeled molecular probe for 18s and 28s ribosomal RNA genes (pX1r101), the karyotypes were shown to contain extensive numerical and structural rearrangements, with up to 24 marker chromosomes.

Abstract
Eleven cases of endometrial stromal sarcoma were obtained from the files of Yale New Haven Hospital from 1969 to 1981 for clinicopathologic correlation and determination of the outcome after hormonal therapy with progestational agents. Histologically, nine of the tumors were classified as low grade stromal sarcomas, and two were of a high grade. All of the patients underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy as the main modality of treatment. Two patients received radiation, three adjuvant chemotherapy, two hormonal therapy (Megace 160 mg qd), three received no therapy at all, and the treatment is not known in one case. Two of the patients who received no therapy had recurrences and were placed on hormonal therapy. The remaining patient was a stage IV and died of disease 3 months after diagnosis. All four of the patients who were treated with hormonal therapy are alive, free of disease, or with stable tumor from 2 to 6 years after diagnosis. The presence of estrogen receptors (ER) and progestin receptors (PR) was demonstrated in the tumor in some of the cases; this may explain the sensitivity of this neoplasm to hormonal therapy.

Abstract
We report the occurrence of rhabdoid cells in several specified soft tissue sarcomas of round cell variety. The rhabdoid cells had an acidophilic cytoplasm containing a globular perinuclear inclusion and were characterised ultrastructurally by the presence of aggregates of 10 nm intermediate filaments. These filaments contained both cytokeratin and vimentin, as demonstrated immunohistochemically. Extensive sampling of soft tissue sarcomas revealed the presence of such cells in different types of soft tissue round cell sarcomas as follows: 12 of 13 cases of epithelioid sarcomas, 8 of 13 synovial sarcomas (composed predominantly of round cells), 6 of 20 extraskeletal myxoid chondrosarcomas and 4 of 4 round celled malignant mesotheliomas. We wish to stress that the appearance of rhabdoid cells is not a monopoly of one particular type of tumour.

Abstract
Immunocytochemical studies of malignant mixed Müllerian tumors revealed the presence of neoplastic cells showing strong immunoreactivity for glial fibrillary acidic protein, a protein specific for astrocytes, in 9 of 13 cases. Undifferentiated malignant tumor cells of endometrial stromal sarcoma and astrocytes in glioma of the uterus also demonstrate GFAP immunoreactivity. GFAP immunostaining in these neoplastic cells is highly specific and shows no cross-reactivity with cytokeratin, actin, myoglobin, epithelial membrane antigen or factor VIII. It is postulated that the GFAP immunostaining within neoplastic cells of Müllerian origin may be a reflection of the phenotypic diversity of intermediate filament proteins that can be expressed by malignant neoplastic cells, that the polypeptides of GFAP may be heterogeneous, that there may be an ontogenic relationship between the cells of Müllerian origin and neuroectodermal cells, or that this may represent neometaplasia of Müllerian cells.

Abstract
Estrogen and progesterone receptors were measured in tissues from 43 patients with various uterine sarcomas using the dextran-coated charcoal assay. Estrogen receptor was present in 55.5% and progesterone receptor in 55.8% of samples, at median estrogen and progesterone receptor concentrations of 10.7 and 15.8 fmol/mg cytosol protein, respectively. These median values are much lower than those in 30 consecutive endometrial adenocarcinomas and 50 breast carcinomas assayed in our laboratory. Progesterone receptor status correlated strongly with estrogen receptor status in uterine sarcomas (P = .001). Estrogen and progesterone receptor levels were not influenced by stage, grade, or mitotic count. Patients 50 years of age or less had significantly higher progesterone receptor than those over 50. No such age effect was seen for estrogen receptor. Endometrial stromal sarcoma had higher estrogen and progesterone receptor levels than other histologic types. Low-grade endometrial stromal sarcomas had higher median estrogen receptors (238.9 fmol/mg) and better survival (all patients alive at 6-12 months) than did high grade (N = 7) endometrial stromal sarcomas (median ER = 6.6 fmol/mg, all dead of disease at 8-27 months). For all histologic types, evaluable patients with stage I or II disease (N = 16) were more likely to survive longer than one year than those with stage III or IV disease (N = 13, P = .003). Evaluable patients with estrogen receptor-positive sarcomas were more likely to survive longer than one year than those with estrogen receptor-negative tumors (P = .006). With one exception, an endometrial stromal sarcoma, hormonal therapy exerted no beneficial effect.(ABSTRACT TRUNCATED AT 250 WORDS)
