AbstractAbstract PDF
Lymphoproliferative disorders, manifesting either as a primary lesion or as part of a generalized process, rarely involve the breast. The primary malignant lymphoma of the breast is rare. The cytologic features of this neoplasm have not been reported in Korea thus far. We described a case of primary malignant lymphoma of the breast, as diagnosed by fine needle aspiration cytology (FNAC) in an 84-year-old female. FNAC smears showed high cellularity. The main cytologic feature observed was a carpeting of monotonous, atypical, enlarged lymphoid cells. These lymphocytes showed relatively round elliptical nuclei with some indentation. One or more prominent nucleoli were seen. Biopy from the breast mass revealed diagnostic features of non-Hodgkin's lymphoma, diffuse large B-cell type.

AbstractAbstract PDF
Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease resulting from infection of oligodendrocytes with JC virus. PML was a rare disease, but nowadays not uncommon as AIDS prevailed. Histopathologic features of the affected lesion shows infiltrations of foamy macrophages and hyperchromatic, pleomorphic, reactive astrocytes that may raise the suspicion of a brain tumor. We recently met with 3 cases of PML. Two of the patients had AIDS and the other had been treated for lymphoma. All cases were diagnosed by histopathologic examination in stereotactic brain biopsies.

AbstractAbstract PDF
BACKGROUND
Giant cell tumors (GCT(s)) of bone are benign but can be locally aggressive neoplasms. Their clinical behavior has been difficult to predict on the basis of histology alone. This study investigated the neovascularization and expression of vascular endothelial growth factor (VEGF) as well as matrix metalloproteinase-9 (MMP-9) in GCT(s) of bone; in addition we evaluated their relationship to clinical behavior.
METHODS
We evaluated the microvessel number and density in 33 samples of giant cell tumor using CD34 immunohistochemistry. In addition, we examined the immunohistochemical expression of VEGF and MMP-9.
RESULTS
The microvessel number alone, not the microvessel density, had statistical association with the clinical stage of GCT(s) (p=0.045). The proportion of cases with strong expression of VEGF increased with advancing clinical stage, however, these results were not statistically significant (p=0.257). The percentage of the cases with strong expression of MMP-9 also increased with advancing clinical stage and this was statistically significant (p=0.022).
CONCLUSIONS
These results suggest that intratumor microvessel count and the expression of MMP-9 correlate with GCT stage. Evaluation of their expression may therefore provide prognostic information on the aggressive behavior of GCT(s) of bone.

AbstractAbstract PDF
Fibromatosis of the breast is a rare tumor. We describe here a case of mammary fibromatosis in a 37-year-old woman. The mass from the right breast was 3 cm at the greatest dimension. The lesion was poorly circumscribed, firm and white-gray on the cut surface. Histologically, the lesion infiltrated into the lobules of the breast, and the tumor was composed of relatively uniform fibroblasts and collagen. Neither mitotic activity nor cellular atypia was seen. On the immunohistochemistry, the cells were positive for vimentin and they were focally positive for smooth muscle actin. Staining results for estrogen receptor and progesterone receptor were negative.
