  • The plasmacytoid variant is an extremely rare form of urothelial carcinoma in which the malignant cells resemble those of plasmacytoma. We report the cytologic features of 3 cases of this disorder. All 3 patients were male and presented with painless macroscopic hematuria. The voided urine cytology revealed a few scattered clusters of tumor cells in a bloody background. Each tumor cell had an abundant amount of cytoplasm that was clear or densely stained and characterized by eccentrically located nuclei. A histological examination of tissue obtained from a radical cystectomy confirmed the cytologic diagnosis in each 3 case, revealing a diffusely infiltrating tumor composed of round, noncohesive tumor cells demonstrating a high nuclear grade. These cells had infiltrated the tunica propria in 2 cases, but were limited to the submucosa in 1 case. The tumor cells were plasmacytoid in appearance, each demonstrating an eccentric nucleus and dense cytoplasm, as seen in the cytologic findings. All of the tumors were immunoreactive for pancytokeratin, CK7, CK20; negative for epithelial membrane antigen (EMA), leukocyte common antigen (LCA), kappa, lambda, and CD79a. Thus, it is important to consider the plasmacytoid variant of urothelial carcinoma in addition to plasmacytoma or lymphoma as a diagnosis when encountering plasmacytoid tumor cells in a voided urine sample.

  • 목적 : 골단일 형질세포종의 방사선 소견을 알아보고자 하였다. 대상 및 방법 : 최근 5년동안 골단일 형질세포종으로 진단받았던 9례의 방사선 소견을 후향적으로 검토하였다. 이 중 2례는 골수검사 소견의 이상으로 대상에서 제외되었고 다른 2례는 전산화단층촬영(1례)와 자기공명영상(1례) 소견의 이상 소견에 의해 대상에서 제외되었다. 결과 : 5례 중 4례에서 단순방사선검사상 경화성 변연이 없는 지도 모양의 골파괴 소견을 보였으며 대퇴골에서 발생한 1예는 골경화증 병변을 보였다. 전산화단층촬영과 자기공명영상 검사는 단순방사선검사에 비해 소주형성을 한 골파괴와 연부조직 침범 등 보다 많은 정보를 보여주었다. 4례의 자기공명영상에서 T 1강조영상에서는 비교적 고신호강도, T2강조영상에서 는 근육보다 약간 높은 중등도 신호강도를 보여주었다. 1례에서는 광범위한 연부조직 침범이 있었고, T1강조영상에서 같거나 저신호강도로, T2강조영상에서는 비균일한 고신호강도를 보이는 다발성 괴사가 있었다. 조영증상 T 1강조영상에서는 괴사부위를 제외한 병변의 강한 조영증강소견이 보였다. 결론 : 전산화단층촬영과 자기공명영상 검사는 골단일 형질세포종의 특징적인 소견의 일부를 보여줄 수 있고 형질세포 침윤이 있는 다른 부위를 찾을 수 있다. 이러한 것들이 골단일 형질세포종의 진단과 치료에 도움을 줄 수 있을 것이다.

  • Multiple myeloma (MM) is a disease reported to account for 1% of all cancers and 10% of hematological malignant diseases. Unlike other malignant diseases that are transferred to the osseous tissues, MM does not show new bone formation, is associated with characteristic osteolytic lesions, and shows monoclonal protein (M-protein) on the immunohematological test, which is an important index in its diagnosis. Solitary lesions of MM are rare in the head and neck area, and, in most cases, MM of the head and neck area is related to systemic sympomts.

  • To develop hybridomas secreting monoclonal antibodies to be used as unlimited sources of reagents indispensable for the diagnosis and treatement of leukemic malignancy, a monoclonal antibody was generated to human pre-T leukemia cells (Jurkat). Hybridomas were produced against Jurkat cell line by fusing spleen cells from hyperimmunized mice with murine plasmacytoma cells (P3$\times$63Ag8. V653). One monoclonal antibody derived from this fusion, designated DMJ-2 was reactive with T-cell lines (Jurkat, Molt-4 and RPMI-8402) and normal peripheral E-rosette forming T cells, but unreactive with B-cell lines (Daudi, Nalm-6) and non-T, non-B cell line (K562). Conclusively DMJ-2 reactive with mature and immature T-lineage lymphoid cells.

  • Multiple myeloma is a clonal neoplastic proliferation of terminally differentiated B-lymphocytes involving the skeletal system in a multifocal fashion. Its oral manifestations are less common in the maxilla than in the mandible due to the lower amount of hemopoietic bone marrow in the maxilla. We report the case of a 50-year-old man who presented with a mass in the left maxillary alveolar region with tooth mobility. The mass had become enlarged after the teeth were extracted 15 days previously. Radiographs demonstrated multiple punched-out radiolucent lesions in the skull and pelvic region. Computed tomography images showed a soft tissue density mass in the left maxilla, eroding the floor and walls of the maxillary sinus. Although several analytical techniques were used to characterize the lesion, it was finally confirmed as multiple myeloma through immunohistochemistry.

  • BiP, immunoglobulin binding protein, is an ER homologue of Hsp70. However, unlit other Hsp70 proteins, regulatory protein(s) for BiP has not been identified. Here, we demo strafed the presence of potential regulatory proteins for BiP using a pull -down assay. Since BiP can bind any unfolded protein, only the ATPase domain of BiP was used for the pull -down assay in order to minimize nonspecific binding. The ATPase domain was cloned to produce recombinant protein, which was then conjugated to CNBr-activated agarose. The structural conformation and ATP hydrolysis activity of the recombinant ATPase domain were similar to those of the native protein, light proteins from metabolically labeled mouse plasmacytoma cells specifically bound to the recombinant ATPase protein. The binding of these proteins was inhibited by excess amounts of free ATPase protein, and was dependent on the presence of ATP. These proteins were eluted by ADP. Of these proteins, Grp170 and BiP where identified. while the other were not identified as known ER proteins, from Western blot analyses. The presence of the ATPase-binding proteins for BiP was first demonstrated in this study, and our data suggest similar regulatory machinery for BiP may exist in the ER, as found in prokaryotes and other cellular compartments.

  • Seven monoclonal antibodies were produced by fusing splenocytes from Balb/C mouse immunized with partially purified human interferon-a (HUIFN-a) with NSO plasmacytoma cells. aery were identified as five IgG class (432.22: IgG2b/n, 460.52: IgG2b/a , 548.46: IgG2a/n , 573.10: IgG2b/h , 625.12: IgG2b/n ), one IgA class (460.50: IgA/n ) and one IsM class (465.27: IgA/n ), and all of them revealed highly sensitive to HUIFN- a IgG class monoclonal antibodies have pts ranged from 8.2 to 8.6. Ascites fluids produced from primed Balb/c mice and were purified through column chromatography. The cytopathic effect (CPE) inhibition assay to examine neutralization of HuIFU-a by IgG class monoclonal antibodies, gave that MAbs 460.52, 548.46, 573.10 can neutralize HUIFU- a arith varying degrees except 432.22. Therefore, it is deduced that these various monoclonal antibodies may recognize the distinct epitopes on HUIFN-a.
