Expression of the pS2 protein in breast carcinoma is a useful guide to evaluate the prognosis and response to tamoxifen. The pS2 protein is an estrogen-regulated 60 amino acid protein which was originally discovered following the screening of cDNA libraries in MCF-7 breast carcinoma cells and is induced through estrogen-dependent transcription of the pS2 gene. The presence of the pS2 protein in breast cancer is considered as valuable as the receptor status, or even more so, in predicting the response to hormonal therapy. We have investigated the pS2 protein expression in 62 cases of primary breast cancer in order to know the relationship between the expression rate of the pS2 protein and hormonal receptor status using immunohistochemical procedures on formalin-fixed and paraffin-embedded tissues. Concomitantly, both the estrogen receptors (ER) and progesterone receptors (PR) were examined using the immunohistochemical technique. Positive staining for the pS2 was seen in forty-nine cases (79%) of the tumors. Forty three cases (88%) of the pS2 positive tumors were ER positive and forty one cases (84%) of the pS2 positive tumors were PR positive ; forty six cases (93%) of pS2 positive tumors were positive for ER and/or PR. The pS2 status correlated significantly with the ER (p<0.0001) and PR (p<0.001). The results reveal a close association between the pS2 protein and either or both the ER and PR status.

2.Relation of internal echo patterns and hemodynamics by incremental dynamic CT in hepatic cavernous hemangioma.
Journal of the Korean Radiological Society 1993;29(4):775-782
To evaluate the correlation between the internal echo patterns and henodynamics in hepatic cavernous hemangioma, we compared the interanal echo pattern with the hemodynamic pattern examined by intravenous bolus CT(multi-phase incremental bolus dynamic CT) in 34 diagnosed hemangiomas (25 patients). We classified cavernous hemangiomas as two different hemodynamic patterns according to the findings of the early phase of intravenous bolus CT scans. Early enhancing type means that most portion of a mass is enhanced during the early hpase and late enhancing type means that only minimal peripheral portion of a mass is enhanced during the early phase. We classified ultrasonogrphic patterns as hypoechoic and hyperechoic according to main echogenicity of the mass. The late enhancing type tends toward the high echo type (20/21) and the early enhancing type tends to ward the low echo type (11/13) (p<0.01) Therefore, we believe that the early enhancing type which represents rapid contrast inflow toward mass, contains large portions of cavernous space and showes hypoechoic, but late enhancing type which represents late contrast inflow toward a mass, contains large portions of fibrous space and showes hyperechoic. In conclusion, there was significant correlation between internal hemodynamics and echo patterns in hepatic cavernous hemangioma.

Generalized pustular psoriasis is a severe form of paoriasis and is frequently associated with arthritis and nail deformity. We present a case of generalized pustular psoriasis in a 40 year-old man, with nail change, arthritis of both knee and ankle joints, spondylitis, and glomerulonephritis. We found a positive results of HLA A-9, B-27 in this patient. Skin lesions, arthralgia and hematuria improved marked1y by plasmapheresis and application of topical corticostertoid.

Kaposi's sarcorna is a tumor-like condition which characterized by a mixed proliferation of fibroblastic components and vascular structures. The authors report a case of nodular type of Kaposis sarcoma in 54 year-old male who had an eroded hemorrhagic nodule and few papular lesions. These lesions involved only both hands and feet without systemic involvement.

We described a 65-year-old woman with a papule on the left temple area of } year duration. The lesion showed typical findings of atypical fibroxanthoma and was located on the lesion of solar keratosis, So sunlight may be the most important one among the various insults to atypical fibroxanthoma of the skin.

The cutaneous metastaaes from carcinoma of breast produce four definite clinical types: inflammatory carcinoma, telangiectatic carcinoma, nodular carcinoma, and carcinoma en cuirasse. We present a case of 51-year-old woman who had purpuric, hard, sclerotic plaque with ulceration, crust and. several pea-sized hemorrhagic papulovesicular eruptions on the right chest wall for one year. Histopathological findings show metastatic ductal carcinoma but, the primary focus was not determined.

Keratoacanthoma is a benign neoplasm that develops as a protruding mass especially on the central part of face, We experienced a case of keratoacanthoma that developed on the nasal vestibule after the eradication of verruca vulgaris on the same site by surgical intervention 3 months before. We treated it with total excision and skin graft.

PURPOSE: To evaluate intrahepatic nodular lesions detected on CTAP but not on conventional contrast CT in regard to its relationship with satellite nodules or borderline malignancies. MATERIALS AND METHODS: From June 1991 to March 1994, CTAP was undertaken in 132 cases with confirmed hepatocellular carcinoma(HCC), of which 35 cases having 82 lesions were suitable for analysis(excluding the cases which had no follow-up studies, showed segmental abnormal portal perfusion, no additional lesions and, or inumerable lesions). The CTAP findings were compared with those on artery dominant imaging studies (angiography, DSA, bolus dynamic CT, arterial CT, Lipiodol CT) taken during the same period(to confirm the presence of lesions) and the findings on follow-up imaging studies(to assess the developemerit of malignancy). RESULTS: Arterial vascularity was identified in 35 of 82 lesions(42.7%) on arterial dominant imaging studies. Developement into malignancy was identified on follow-up imaging studies in 25 of remained 47 lesions(53.2%). CONCLUSION: The total positive predictive value of nodules on CTAP was 73.2%(35+25/82), but the predictive value for HCC by follow-up only was 53.2%. Given'the difficulties in detecting intranodular arterial flow and the short follow-up duration in many patients, the actual positive value might be higher.
