 Abstract
- Recently, p53, c-erbB-2 and nm23 proteins have been studied in breast cancer. The expression of p53 protein indicates the mutation of p53 gene known as a tumor supressor gene, and c-erbB-2 gene amplification has been considered an indicator of poor prognosis and nm23 a metastsis suppressor gene. In order to elucidate the roles and relations of these proteins in the develpoment, progression and metastasis in breast cancer, we studied 89 cases of invasive breast cancer and 32 cases of lymph node metastasis for the expression of p53, c-erbB-2 and nm23 proteins using an immunohistochemical method. The results were as follows: 1) The expression rates of p53, c-erbB-2, and nm23 proteins in breast cancer were 40.4%, 34.8% and 55.1%, respectively. Co-expression of p53 protein and c-erbB-2 protein was found in 20.2% of cases, showing the highest incidence in poorly differentiated type (40%). 2) p53 protein expression was increased in poorly differentiated type but was not statistically significant.
On the other hand, the expression of nm23 protein was decreased in poorly differentiated type, which was statistically significant (p<0.05). 3) The correlation of p53 protein expression with c-erbB-2 protein expression was statistically significant (p<0.05) but that with nm23 protein was not. 4) In the cases with lymph node metastasis, discordant expression of p53, c-erbB-2 and nm23 proteins between primary tumor and the lymph node metastatic tumor was found in 9.4%, 3.1% and 18.8% of cases, respectively.
The above results suggest that overexpression of p53 and c-erbB-2 proteins and downregulation of nm23 protein are associated with the tumor progression in the breast cancer.

Abstract
- Prolymphocytic leukemia is a chronic lymphoproliferative disorder, characterized by prominent splenomegaly, prolymphocytes accounting for more than 55% of circulating lymphocytes, no significant peripheral lymphadenopathy and short term survival with terminal fatal multi-organ failure.
We report a case of B-cell prolymphocytic leukemia in a 57-year-old woman who presented with easy bruising and arthritis for 1 year and low abdominal pain for 2 months.
Physical examination revealed gingival hypertrophy and mild splenomegaly. On peripheral blood smears the leukocytes were markedly increased in number due to leukemic cells that count about 62% of leukocytes. The bone marrow aspiration smear and biopsy revealed diffuse infiltration of medium to large prolymphocytes having moderate amount of basophilic cytoplasm, round to oval nuclei with coarse chromatin, and prominent nucleoli. Abdominal pain aggravated despite chemotherapy, and pelvic computed tomography (CT) revealed a huge lobular pelvic mass which had increased in size on the follow-up CT. Total hysterectomy with bilateral adnexectomy was performed. Microscopic findings included massive infiltration of prolymphocytic cells in the uterus, upper vaginal wall, bilateral ovaries, and bilateral mesosalpinges. On immunohistochemistry, the leukemic cells showed B cell gamma light chain phenotype.

- Infection by pseudallescheria boydii is an occasional cause of mycetoma, corneal ulcers, endophthalitis, sinusitis, pneumonia, endocarditis, meningitis, arthritis, and osteomyelitis. But, it also causes serious disseminated or localized infection in immunocompromised patients. We report a case of pulmonary pseudallescheriasis developed in a 32-year-old man who has been a sofa manufacturer for several years. He presented with a cystic mass in the lung, 5cm in the largest dimension. Dark green necrotic material was evacuated from the cavity. Microscopically, the cystic wall and adjacent lung parenchyme were infiltrated by histiocytes rather than eosinophils and there was little fibrosis in the wall. The P. boydii was isolated from the cystic contents, which revealed white floccose colonies in Sabouraud dextrose agar and revealed single or multiple-celled oval conidia being produced on short hyalinated hyphae and on the elongated annellides in the slide culture. The differential findings with aspergillosis are discussed.

Abstract

- We performed dual color fluorescence in situ hybridization (FISH) for the bcr/abl fusion in CML using the peripheral blood smears without destruction of cell morphology to determine the bcr/abl fusion. Two patients of CML, one patient in accelerated phase and one patient in chronic phase, were selected. The blood smears were fixed in absolute methanol. FISH was performed with the Mbcr/abl translocation DNA probe mixture and the slides were stained with Wright's stain after FISH. The blood smears of both cases revealed distinct signals without destruction of cellular morphology. The normoblasts and lymphocytes revealed beautiful fused bcr/abl signals as well as granulocytes in both cases. The results provide a novel finding that the normoblasts and lymphocytes in CML are also neoplastic clonal cells which has not been demonstrated with a single-cell approach before.

Abstract

- A case of multiple myeloma associated with adenocarcinoma of the stomach was review. A 59-year, old Korean man had been abmitted to St. Mary's Hospital in January 1984, with chief complaint of posterior neck pain, and intermittent headache for one year prior to amission. Osteo lytic punched-out lesions were noted on skull and other skeletal x-ray films.
Bone marrow aspirates revealed diffuse infiltration of mature and immature plasma cells. Laboratory findings revealed anemia and Bence-Jones proteinuria.
Immunoelectrophoresis revealed findings consistent with IgA-lamda type multiple myloma. Alkylating agents and steroids were tried with some clinical improvements. In August 1985, the patient revisited outpatient clinic with chief complaints of epigastric pain and neck mass.
Endoscopic biopsy and excision biopsy of the cervical lymph node were performed. By microscopic examination, adenocarcinoma of the stomach and metastasis of multiple myeoma to the supraclavicular lymph nodes were confirmed.
Subtotal gastrectomy was performed. By gross and microscopic revealed metastasis to the regional lymph nodes.
