RESUMEN
Uterine sarcoma is a rare female neoplasm that accounts for about 2-4% of all uterine malignancies. According to the classification of Norris and Taylor, the subgroup of endometrial stromal sarcoma (ESS), comprising approximately 7-15% of all uterine sarcomas, can be divided into low-grade ESS and high-grade ESS and is characterized by proliferations composed of cells with endometrial stromal cell differentiation. We experienced this infrequent malignant tumor in a 52-year old woman and was treated by total abdominal hysterectomy with bilateral salpingo-oophorectomy followed by adriamycin chemotherapy. We present a case of low-grade ESS with a brief review of the literature.

OBJECTIVE: We studied the possibility that addition of Tyrphostin AG 1478 which is selective epidermal growth factor inhibitor, would enhance the effect of radiation on human cervical cancer cell lines, HeLa and CaSki. METHODS: Tyrphostin was added to the cells which were irradiated. The ratio of dead cells was estimated by trypan blue dye examination, and survived cell fractions were estimated by clonogenic assays. The presence and degree of apoptosis were examined by DNA electrophoresis and nuclear dye using propium iodide. RESULTS: The growth was completely inhibited in both cell lines, but the addition of tyrphostin resulted in different effects on the radiation induced cell death and apoptosis in each cell line. However, the percentage of dead cells and apoptotic cells was decreased in HeLa cell line compared with CaSki cell line. The ultimate survived cell fractions determined by clonogenic assays were decreased in both cell lines and the size of colony was also decreased. CONCLUSION: These data suggest that the addition of Tyrphostin is able to increase the radiotherapeutic effects on human cervical cancer cells, and this synergistic effect may result from effective blocking of radiation-induced accelerated repopulation of cancer cells by tyrphostin.

A virus-associated hemophagocytic syndrome is characterized by high fever, liver dysfunction, coagulation abnormalities, pancytopenia, and a benign histiocytic proliferation with prominent hemophagocytosis in bone marrow, lymph node, spleen, and liver. Three phases of disease progression can be defined. In the first week, there is mild leukocytosis and myeloid hyperplasia in the marrow and the fever is resistant to antipyretics and antibiotics. In the second phase, usually corresponding to the 2nd to 3rd week of the illness, the fever persists and jaundice and hepatosplenomegaly may develop and the marrow now reveals the presence of atypical or transformed T lymphocytes and a scattering of histiocytes with hemophagocytosis. In the third phase, the disease progresses to a full-blown hemophagocytic syndrome with coagulopathy and lung infiltrates. The marrow in this stage is usually hypoplastic with florid histiocytic proliferation and hemophagocytosis and the patients usually die within 1-2 months. We describe a pregnant woman with fatal hemophagocytic syndrome. Virologic study strongly suggests that Epstein-Barr virus implicated in the pathogenesis of this patient.
