Granulosa cell tumor and concurrent endometrial cancer with (18)F-FDG uptake.

The findings and the role of fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) for the diagnosis of ovarian granulosa cell tumor (OG) are described. We present the pre-operative findings of (18)F-FDG PET/CT scan of a case of OG concurrent with endometrium cancer and endometrial hyperplasia, which revealed a 48mm mass demonstrating mild increased metabolic activity on the right ovary. Total abdominal hysterectomy and bilateral salpingo-oophorectomy was performed. Frozen and paraffin-enbeded sections showed an encapsulated OG. There were few mitoses. There was concurrent atypical endometrial hyperplasia. In conclusion, we reported a case of an encapsulated OG, which showed mild uptake of the (18)F-FDG with concurrent endometrial cancer. There has been only one report of (18)F-FDG findings in primary ovarian granulosa cell tumor, similar to ours.

Morphometric development of sphincter of oddi in human fetuses during fetal period: microscopic study.

OBJECTIVE: In this study, morphometric developments of the sphincter of Oddi in human fetuses were observed. MATERIAL AND METHODS: We observed 113 human fetuses consisting of 67 male and 46 female subjects, whose ages varied between 14 to 40 weeks who showed no signs of any pathology or anomaly externally. The common external measurements of fetuses were carried out, followed by abdominal dissection to determine where the sphincters of Oddi were localized within the duodenum and pancreas. Histological specimens of tissue samples were gathered from the inner wall of the duodenum where it was assumed that the sphincters of Oddi had been localized. The parameters of total external diameters, lumen diameters, wall thickness, diameters of ductus choledochus and ductus pancreaticus, and the distance between these two structures, which are also known as the origins of the sphincter of Oddi, were measured by using a light microscope. The standard deviations of the measurements were calculated for each gestational week and trimester. RESULTS: The calculations suggested that there were statistically significant correlations between gestational age and all of the other parameters with the exception of the ductus choledochus (p<0.001). It was observed that the wall thickness of the ductus choledochus increased at the first half of the fetal stage and decreased at the second half, as the lumen diameter increased through the 40th week. The gender difference was not statistically significant (p>0.05). CONCLUSION: The data we collected in our study were considered as useful for the evaluation of the development of the sphincter of Oddi area and fetal stage.

Pulmonary carcinosarcoma: a case report.

Pulmonary carcinosarcoma, belonging to sarcomatoid carcinomas, is a quite rare tumor that contains both malignant epithelial and mesenchymal elements. This tumor has different phenotypic characteristics and clinical course compared to non-small cell lung tumors. A case diagnosed as carcinosarcoma is presented and its clinical and pathological features and the differential diagnosis are discussed. The case was a 74-year-old male admitted with shortness of breath and cough. The chest x-ray showed a left lung mass and a bronchoscopic examination was performed. Histopathological examination of the bronchoscopic biopsy showed necrosis and a malignant tumor consisting of diffuse infiltrative anaplastic cells. Surgery was performed and the case was diagnosed as carcinosarcoma in the resection material. Pulmonary carcinosarcoma is a rare lung tumor. Determination of tumoral cells and performing advanced investigations in resection material seem to be relatively easier than in small biopsies. However, this type of tumor can be encountered in small biopsy materials as in the presented case and should be kept in mind in relation to the differential diagnosis as small tissues can have only one, particularly mesenchymal, tumoral component.
