Forty-five patients with primary neoplasm of the spine, disgnosed and operated at Dept. of Orthopedic Surgery, Seoul National University Hospital, from 1970 to 1988, were reviewed in an attempt to analyze the incidence of the primary spine tumors and effectiveness of surgical treatment. Mean follow-up was 2.5 years. Among 29 benign tumors, 7 cases of osteoid osteoma, 6 cases of giant cell tumor, 4 cases of osteoblastoma and aneurysmal bone cyst, and 2 cases of fibrous dysplasia and osteochondroma, and others were identified. Of 16 malignant tumors, 6 cases of eosinophilic granuloms, 4 cases of chordoma, 3 cases of solitary plasmacytoms, and others were noted. 17 cases occurred in the anterior compartment, 18 cases in the posterior compartment, and 10 cases involved both compartments. Surgical treatment consisted of complete or near complete excision, decompression, and additional stabilization procedure when the stability of the vertebral column was compromised. Stablization was achieved either by fusion, strut bone graft, or by additional Zielke, Cotrel-Dubousset, or Luque-Harringtion instrumentation. The results were astisfactory in most of the cases with benign tumors except cases of giant cell tumor. The results in malignant tumor were satisfactory especially in eosinophilic granuloma and solitary plasmacytoma with respects to symptoms and survival, and this fact was attaibuted to good response to adjuvant chemotherapy and radiation therapy. Recent application of Cotrol-Dubousset or Zielke instrumentation after agressive resection made early ambulation a clinical reality.

Histoid leproma usually occur in pat.ients with lepromatous leproy who have had relapsed after being undcr treatment(usually sulfones) for a long time and who have shown variable improvement. A 56 year old female patient who had been suffering from lepromatous leprosy and had been treated which clapsone relatively regularly for approximately 28 years had a history of several shiny rice grain t.o peanut sized nodules on the face and right flank. Histopathologic examination of a specimen taken from a nodular lesian revealed a well circirmscrihed nodule composed mainly of spindle-shaped cells and epithe:ioi 1 cells on the upper and mid-levmis, and granuloma composed of epithelioid cells, multinucleated wait cells and foamy histiocytes on the lower dermis. In AFB stain, numerous acid-fast bacilli were scatt red dermis and epidermis, especially stratum corneum. This study opplied a polymease chain reaction(PCR) on sections of biopsy tissues and peripheral blood of pat.ient. Positive amplification of a 530 bp fragment was deteated not only in the lesion tissues but also in the per ipher al blood.

BACKGROUND: Recent clinial observations have suggested that colchicine, which is in frequent use in gout can affect the conneciive tissue metabolism in skin and other ti.ues. OBJECTIVE: This study suggest that further development of colchiine might provide a novel means of modulating collagen gen expression in patients with fibrotic disease. METHOD: We examed the effect of colchicine on the expres, on of collagen, fibronectin and collagenase gene by skin filroblast culture hy Nort.hern and dot-blot iybridization. Result : The rate of transcription of genomic DNA corresponding o type I collagen and libvonectin was reduced in colchicine-treated cultures but collagenase was not. reduced. Canclusion : The microti.ikile disruptive agent, colchicine, reduced the expression of type I collagen and fibronectin in a dose-(lependent manner. This st.udy suppor that colchicine is one of the promising antifibrogenic drugs curvently being tested as a treatment, of hun an fibrotic disease.

Modified Mohs surgery is a procedure which eliminated chemical fixation step from Mohs chemosurgery. This technique is faster, less painful and more tissue conserving, allows for immediste repairs, yields higher quality histologic preparations and facilitates an interdisciplinary apporoach; it is the treatment of choice for recurrent or difficult skin cancers. A 58-year-old femele patient presented with a 2x 3cm sized dark brownish, ulcerated nodule on the left upper eyelid. Histopathologic findings revealed several small solid nest composed of basalioma cells in the dermis. We treated with modified Mohs surgery and obtained good result.

Transforming growth factor beta(TGF-p), initially identified in vlatelet extracts by virtue of its ability to confer anchorage of independent growth and a necplastic phenotype on mesenchymal cells, has subsequently been identified as a potent inh bit or of proliferation in most cells of epithelial origin. The family of TGF-p peptides is currenly onsisted of four subtypes (TGF-pl, p2, p3, p4). Tkiey are initially translated very larged are urssors of approximately 390 amino acids and produced by a wide variety of cell type. iricluding normal cells and tumor cells. TGF-ps promote deposition of extracellular matrix compcineits, facilitate remodeling events during embryonic development, and suppress immune ce 1 fimetion during the inflammatory process. Several nutaneous diseases are characterized typxcessive and progressive fibrosis of the dermis anil subcutaneous tissues. Prominent amon these disorders are progressive systemic sclerosi(PSS) and generalized morphea(GM), is well as the recently described syndrome of diffuse fasciitis eosinophilia(DF), also known; Shulmans syndrome. The hallmark of the pathologic alteration in these disorders is the excessive deposition of collagen and other connenctive iissues. Macromoleculse in the aerriis and/or the subcutaneous and fascial strutures often accompanied by variable degress of hronic inflammatory cell infiltrates. Now we have examined the expression of TGF-b1 mRNA using of northern blot hybridization with specific sequenced cDNA probe in the normal curltured fibroblasts, placental tissues, and fibrosarcorna derived tumor cell line(HT1080). We found that the size of TGF-b mRNA of each specimen was 2.5kb and theres no alteration of its quality.

Eccrine spiradenoma is clinically characterized by a solitary, movable, tender nodule occurring most frequently on the ventral surface of the upper body. A striking symptom is paroxysmal pain. Occasionally multiple lesions may be present and may occur in a linear or zosteriform pattern. A 48-year-old female was seen with painful or tender, nomal skin colored, firm nodules distributed in a zosteriform pattern on the right thigh for 10 years, which had been slowly growing. The histopathological features were quite a characteristic of eccrine spiradenoma. We report a rare case of zosteriform network of eccrine spwadenoma occurred on the right thigh.

We present a case of lymphangioma circumscriptum in a 17 year-old girl according to tihe clinical and histopathological findings. This case is unusual in that lesions developed on the vulva and thigh without preceding lymphedema. Our patient had a plaque of grouped vesicle-like papules resembling frog's apawn on The both labia majora of vulva and several scattered, skin tag like soft papules on the right upper thigh of theree years duration. Histopathologic findings showed variable sized, dilatated lymphatic channels lined by single layer of normal endothelial cells confined to the only upper dermis.
