Solid and papillary epithelial neoplasm of the pancreas is a rare, low grade malignant tumor of adolescence. The tumor we described was diagnosed by following preoperative percutaneous fine needle aspiration biopsy and confirmed by tissue examination. Characteristic cytologic findings were monotonous cells arranged in papillary fronds, acinus, and cords in necrotic and hemorrhagic backgrounds. Occasional foamy histiocytes and hyaline globules were present. The cytoplasm of the tumor cells were moderate in amount, pale eosinophilic or vacuolated with distinct borders. The nuclei were centrally located and round. There were one or two small nucleoli and finely granular chromatin throughout the nucleus.

This is a case of recurrent malignant fibrous histicytoma, histologic features of which are reminiscent of a clear cell carcinoma of soft tissue or myxoid liposarcoma. The tumor recurred 2 years and 10 months after the initial removal of the primary tumors in the lateral aspect of the left tigh. In view of histogenesis of malignant fibrous histiocytoma, possibility of recurrent tumor with a wide range of histologic features including clear cell type is discussed. Pertinent clinical history with review of the initial tumor is mandatory for a definite assessment of histologic feature of recurrent malignant fibrous histiocytoma.

PURPOSE: Although breast reconstruction provides some advantages for women following mastectomy, few Korean breast cancer patients currently receive such reconstruction. Routine provision of breast reconstruction requires simplicity and easy availability for the procedure. This paper reports the possibility of performing breast reconstruction by insertion of a tissue expander by the breast surgeon. METHODS: We studied 22 cases of breast cancer patients who were treated in the Breast service of KangNam Cha Hospital. Nine cases were the group of immediate expander insertion and 13 were the group of MRM only. We evaluated age, histopathologic stage, starting time of chemotherapy, operation time, drainage amounts and periods, medication periods, time of discharge and depression score. RESULTS: The mean age of the expander insertion group was 41, which was younger than that of the MRM only group by 3 years. Histopathologic state was better in the expander insertion group and the time for chemotherapy start was almost the same between the two groups. Mean operation time in the expander insertion group was 2 hours and 41 minutes, and it was longer than the MRM only group by 1 hour, but it included additional wasting time to check the results of frozen biopsy. Periods for drainage were longer and amounts were larger, but this only delayed the medication period and time for discharge by two days. There were no other complications and mental suffering was alleviated. CONCLUSION: Tissue expander insertion for breast reconstruction could be offered on a routine basis by breast surgeons without problems. Breast reconstruction will become a more essential process for breast cancer patients to improve the quality of life. It is ideal if the same surgeon participates in both oncology and reconstruction surgery.

One hundred twelve cases of cervical intraepithelial neoplasia (CIN) were reviewed to detect the condylomatous lesion characterized by koilocytotic cells. Condylomatous lesions were present in 12 cases (30.8%) of 39 cases with mild dysplasia, 3 cases (15.0%) of 20 moderate dysplasia, 2 cases (13.3%) of 15 severe dysplasia and 4 cases (10.5%) of 38 cases with carcinoma in situ. These 21 cases with condylomatous lesions were subjected to the study on demonstration of human papillomavirus (HPV) antigen with peroxidase antiperoxidase reaction and 6 simple condylomatous lesions of the uterine cervix were included for control. Twenty seven cases with simple cervical condyloma and condylomatous lesions associated revealed 22 cases of flat type, 3 cases of exophytic type, 1 spiked type, and 1 inverted type. Cells showing a positive reaction for HPV antigen were identified in 5 cases (55.6%) of 27 cases with condylomatous lesions. HPV antigen positive nuclei were found chiefly in koilocytotic cells. The prevalence of HPV antigen positive cells was well correlated with the extent and intraepithelial level of the koilocytotic changes. The results of this study provide a confirmation of the presence of HPV antigens in CIN, and suggest that the HPV may be an important factor in the etiology of CIN.

We studied 24 cases of cutaneous T-cell lymphomas and six cases of benign lymphoproliferative diseases of the skin (2 Jessner's lymphocytic infiltration, 2 pseudolymphoma, 2 lymphomatoid papulosis) for the presence of Epstein-Barr Virus(EBV) RNA, using the in situ hybridization(ISH) method. Among the 24 cases of cutaneous T-cell lymphomas (CTCL), 18 cases including 12 cases of mycosis fungoides(MF) were primary CTCL, and the other 6 cases were secondary CTCL. The ISH study demonstrated a positive reaction for EBER probe in 6 out of the 24 cases(25%) of CTCL, and a negative reaction for BHLF nuclear RNA probe in all the cases studied. Double-labelling immunohistochemistry/ISH studies revealed that the EBV positive cells were CD45RO positive and CD20 negative. EBV genome was not demonstrated in any benign lymphoproliferative diseases of the skin. Among the EBER positive cases, none of the 12 cases of MF demonstrated EBER signals, and 6 out of the 12(50%) cases of CTCL were positive for EBER probe. In conclusion, latent infection of EBV may play a role in the development of non-mycosis fungoides T-cell lymphomas involving the skin.

Lipodystrophia centrifugalis abdominalis infantilis, an typical form of progressive lipodystrophy, is a disease mainly decribed in japanese infants. We report a case of lipodystrophia centrifugalis abdominals infantilis in Korean infant. The patient is a 2 year-old-girl with a coin sized well defined depressed lesion with surrounding redness and scaly changes in the right inguinal region. The skin from the depressed lesion revealed changes similar to those originally described by Imamura et al.

Cervical intraepithelial neoplasia in human consist of dysplasia of various developmental stages and squamous cell carcinoma in situ of various types. These lesions can be diagnosed cytologically on cervico-vaginal smears, although the diagnostic reproducibility is limited. To obtain the objects morphologic distinction between normal squamous epithelial cell in different maturation, different stages of dysplastic cells and varieties of in situ carcinoma cells, Kontron IBAS-1 imaging analyzer was applied for the measurement of nuclear and cytoplasmic areas of each categorised cells. The followings are results obtained: 1) Nuclear and cytoplasmic areas of superfical (36.9 micrometer2, 2319.9 micrometer2) intermedicate (45.7 micrometer2, 2989.7 micrometer2) and parabasal cells (50.8 micrometer2, 432.7 micrometer2) of normal squamous epithelium origin are mostly distinctive between cell types. However, cytoplasmic areas of both superficial and intermediate cells and nuclear areas of both intermediate and parabasal cells are not significantly different. 2) Normal squamous cells and various dysplastic cells show obvious difference in their nuclear and cytoplasmic areas, while difference between cytoplasmic areas of both parabasal (432.7 micrometer2) and severe dysplastic cells (409.7 micrometer2) are not statistically significant. 3) No statistical difference is observed in between nuclear areas of both moderate dysplastic (112.3 micrometer2) and severe dysplastic cell (117.6 micrometer2). 4) Varieties of carcinoma in situ cells and severe dysplastic cells are in difference in their nuclear and cytoplastic areas, whereas nuclear areas from both in situ carcinoma cells (95.3 micrometer2) of large cell type and severe dysplasia (117.6 micrometer2) are not distinctive. The results lead the author to consider that the morphometric analysis for various parameters of cell constituents are of value in making objective distinction between cells from cervical intraepithelial neoplasia in human.

The authors reviewed surgical materials from 20 patients with carcinoma of the extrahepatic biliary system, and a correlation between macroscopic appearance of the tumors with various clinical features and histopathologic findings was made. Microscopically, the tumors were classified into four types; Four (21%) patients had polypoid tumors, six (32%) had nodular growths, five (26%) were scirrhous constricting in type, and four (21%) had diffusely infiltrating type. Histologically all the differentiation in two cases. The degree of differentiation of the tumors was classified into 3 types: 11 (55%) patients were well differentiated, 3(15%) were moderately well and 6(30%) were poorly differentiated. All polypoid tumors were well differentiated and had low stage. No correlation in the degree of differentiation of the tumor with the stage was present. No correlation in clinical symptoms, duration of symptoms, laboratory findings with morphologic findings of the tumors was noted.
