체성 연부 조직에 생기는 평활근육종은 매우 드물다. 66세 남자 환자가 방사선 소견상 경계가 좋은 양성 종양이 의심되어 절제술을 시행 받았다. 육안조직소견상 경계가 좋은 둥근 종괴이나, 현미경 소견에서 세포충실도가 증가되고 부분적으로 중증도의 핵이형성을 보였다. 또한 면역조직화학염색상 Smooth muscle actin과 Desmin에 동시에 양성이어 평활근세포 기원으로 생각되었다. 저자들은 괴사가 없고 유사분열은 단 한 개만이 관찰되었으나 중증도의 핵이형성을 보였기에 평활근육종으로 진단한 증례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Leiomyosarcoma of somatic soft tissue is a rare tumor compared with retroperitoneal lesion. We report a case of a leiomyosarcoma of the somatic soft tissue in a 66-year-old man. He presented as an enlarging mass in the left thigh for eight months. Radiologic examinations revealed a well defined round mass, suspicious of benign tumor, such as hemangioma or leiomyoma. He underwent surgical resection. The mass was 3.0 cm in diameter, and it was confined within adductor longus muscle without any connection to adjacent neurovascular bundles. Histologic examination showed moderately cellularity and focal marked atypia with a fascicular growth pattern of spindle cells showing blunt ended nuclei. In addition, the proliferation index was 2~3% by immunohistochemistry using monoclonal antibody MIB-1. But only one definite microscopic mitotic feature was found. Although it showed low mitotic activity without necrosis, this case was diagnosed leiomyosarcoma according to marked cellular atypism.

N/A Background : The green fluorescent protein (GFP) from jelly fish, A equorea victoria, has become a versatile reporter for monitoring gene expression in a variety of cells and organisms . Using GFP as a marker protein we studied whether there are any differencies in the expression patterns among organs in mouse after intravenous injection of adenovirus vectors with GFP gene. Methods : Recombinant E1, E3- defective type 5 adenovirus vectors (2×10(8)/mouse) with CMV promoter and GFP gene were injected into mice via tail vein. On 3, 6, 9, 14, 21, 28 days after gene transfer, 5 mice per experiment s were sacrificed by cervical dislocation and obtained liver , lung, heart , kidney, spleen, small intestine and bone. Half of them were examined by optical microscope after H-E stain. Another half were examined by fluorescent microscope after frozen section. Western blotting were done for each samples with anti- GFP monoclonal antibody and obtained GFP bands were quantitatively compared using Gel-Doc (Bio- Rad, USA) image analyzer. Results : In all organs that we obtained, expression of GFPs are noticed 3 days after gene transfer and reached a maximum around 9th to 14th days, after then the intensities are slightly decreased but maintained until 28th days as determined by Western blotting. On fluorescent microscopic examination, GFPs are well and most frequently expressed on lung among all the examined organs. There are little expression of GFPs on liver parenchymal area around the sinusoids and central veins, although patchy expression of GFPs are observed along the liver capsules. GFPs are highly expressed around the splenic trabecula area but splenic pulp area, it is very spar sely expressed. GFPs are more frequently and highly expressed around the renal tubular area than gromerular area in kidneys. In small intestine, GFPs are expressed on mid portion of microvilli. GFPs are not expressed on myocardium except scanty expression on endocardium. Bone marrow showed GFPs but precise localization is difficult because bony spicules mashed bone marrow during the preparation of frozen section. No specific pathologic lesions possibly related with adenovirus administration are observed on microscopic examination of H-E stained specimens. Conclusions: GFPs can be detected in cells without the fixing and staining and a good marker to studying the kinetics and persistence of adenovirus mediated gene therapy. And there are different GFP expression patterns according to the organs after intravenous injection of adenovirus vectors with GFP gene in mouse.(Korean J Med 61:537- 545, 2001)
