Kupffer cells are tissue macrophages (histiocytes) fixed in hepatie sinusoids. Since malignant hepatocytes are the only tumor parencymal cells of the hepatocellular carcinoma, theoretically there are no Kupffer cells within the hepatocellular carcinoma. To clarify whether it is true or not, 12 cases of hepatocellular carcinoma of the trabecular type with some extents of the non-neoplastic surrounding liver were subjected to immunoperoxidase staining for lysozyme and S-100 protein and the results are as follows. 1) Kupffer cells were stained positively by the immunoperoxidase staining for lysozyme but not for S-100 protein, indicating that they are monocyte derived macrophages. 2) Kupffer cells were also present within the hepatocellular carcinoma, but were 2-7 times fewer within the hepatocellular carcinoma than in the non-neoplastic areas (p<0.05). 3) The non-neoplastic hepatic tissue of patients with serum HBsAg shows a tendency to have more kupffer cells than those without HBsAg.

The authors attempted to choose what has the best reproducibility and predictability for prognosis of the prostatic adenocarcinoma among four most widely used gradings methods; the Gleason's Mostofi's, Bocking and MD Anderson hospital systems. According to these gradings systems, each of two pathologists made histologic gradings of 40 consecutive prostatic adenocarcinomas which had been diagnosed with the surgically resected specimens. Correlation between the histological grades and the clinical stages was studied and a comparison was made among each system. For the comparison, the Gleason's and MDAH systems were revised as 3 grades and adjusted to the other gradings systems. In this study, MDAH grading system yielded the highest reproducibility as represented by 90% agreement, as compared with the other systems which showed 82.5~87.5% agreement. By the Gleason's, Mostofi's and Bocking's systems, 46.2%, 23.1% and 46.2% of grade 3 tumors respectively fell under the clinical stage A. On the contrary, there were no cases of grade 3 in stage A and no cases of grade 1 in stage D, by MDAH gradings system. These results suggest that MDAH gradings system is superior to the other systems in reproducibility and for predicting the biological behavior.

Primary pericardial tumors are rare than those originating within the myocardium or endocardium and, moreover, primary benign pericardial tumors are much rare in occurrence. Fine(1986) was able to collect only 43 cases of lipoma. Most cases are diagnosed only at autopsy. One fourth of the cardiac lipoma arise subepicardially, where they suggest the presence of pericardial effusion with compression or displacement of the heart. A case of primary intrapericardial lipoma simulating pericardial effusion is presented. This tumor originated in left anterior aspect of pericardium. The tumor was measured 30x30x5cm in size and 2,200mg in weight. Total excision of the mass was accomplished by posterior lateral thoracotomy incision, resulting in complete cure. This is the first case of primary benign lipoma of the pericardium in literatures in our knowledge.

PURPOSE: Complete fibrovascular ingrowth within the hydroxyapatite ocular implant is necessary for peg drilling which is performed to prevent infection and to provide motility to the ocular prosthesis. We compared planar bone scintigraphy and SPECT for the evaluation of the vascularization within hydroxyapatite ocular implants. MATERIALS AND METHODS: Seventeen patients (M:F=12:5, mean age: 50.4+/-17.5 years) who had received a coralline hydroxyapatite ocular implant after enucleation surgery were enrolled. Patients underwent Tc-99m MDP planar bone and SPECT imaging by dual head gamma camera after their implant surgery (interval: 197+/-81 days). Uptake on planar and SPECT images was graded visually as less than (grade 1), equal to (grade 2), and greater than (grade 3) nasal bridge activity. Quantitative ratio of implanted to non-implanted intraorbital activity was also measured. Vascularization within hydroxyapatite implants was confirmed by slit lamp examination and ocular movement. RESULTS: All but three patients were considered to be vascularized within hydroxyapatite implants. In visual analysis of planar image and SPECT, grade 1 was noted in 9/18 (50%) and 6/18 (33%), respectively. Grade 2 pattern was 7/18 (39%) and 4/18 (22%), and grade 3 pattern was 2/18 (11%) and 8/18 (44%) respectively. When grade 2 or 3 was considered to be positive for vascularization, the sensitivity of planar and SPECT imaging were 60% (9/15) and 80% (12/15), respectively. In 3 patients with incomplete vascularization, both planar and SPECT showed grade 1 uptake. The orbital activity ratios on planar imaging were not significantly different between complete and incomplete vascularization (1.96+/-0.87 vs 1.17+/-0.08, p>0.05), however, it was significantly higher on SPECT in patients with complete vascularization (8.44+/-5.45 vs 2.20+/-0.87, p<0.05). CONCLUSION: In the assessment of fibrovascular ingrowth within ocular implants by Tc-99m MDP bone scintigraphy, SPECT image appears to be more effective than planar scintigraphy.
