BACKGROUND: Several modalities have been used for the treatment of livedo vasculitis. However, in some cases conspicious morbidity is caused by recurrent painful ulceration resistant to therapy. OBJECTIVE: This study was conducted to determine the effectiveness and adverse effects of the danazol in treatment of livedo vasculitis. METHODS: Nine patients with ulcerative lesions due to livedo vasculitis were included for danazol therapy. Danazol 200mg was administered daily for 4 to 8 weeks. RESULTS: Eight of the patients showed remarkable improvement and were satisfied with this therapy. Significant adverse effects were not observed. CONCLUSION: We suggest that a low dose of danazol may be considered as the first line of treatment and is worthwhile to try in cases recalcitrant to the other treatment.

30 year-old female patient with acutely ill appearance was admitted to Sacred Heart Hospital because of high fever, nausea and, vomiting and severe headache 4 days duration. On physical examination, slight stiffness of the neck and Kernig's sign was noted. Skin signs showed rice sized erythematous grouped papulovesicular eruption on the right side of the neck and chin. C.S.F. findings were elevated pressure, increased protein and decreased sugar level of C.S.F. On funduscopic examination, revealed slight papilledema and mild blurring of the disc margin. Skin biopsy was performed on the vesicular lesion and showed marked ballooning degeneration of cell in which an inclusion body was present. She was healed completely after treatment with analgesics and corticosteroids.

A case of cutaneous cartilaginous tumor was diagnosed from solitary nadular skin lesion on a toe of 59-year old female. Lack of information about cartilage tumors in the dermatologic literature suggest that they rarely develop as supeficial lesions. General clinico-pathologic feature of the tumor is reviewed.

Normal human glomerular basement membrane (GBM) and mesangial matrix (MM) contain several different basement membrane components in varying degrees. The characteristic morphological and ultrastructural changes in patients with diabetic nephropathy are the thickening of the GBM and the expansion of the MM. In order to investigate the changes of extracellular matrix components in diabetes, the immunohistochemical localization was performed in 17 cases with different degrees using antisera to human collagen types I, III, IV, VI, fibronectin, and laminin. The following results were obtained: 1. The reactivity for collagen IV was increased in expanded MM in the diffuse glomerulosclerosis (GS). With the progression to the nodule formation, collagen IV was prominently decreased in the peripheral area of the nodules. 2. Collagen VI was increased in GBM and MM in the diffuse GS, it was especially prominent in the expanded MM. With the progression to nodule formation, collagen VI was prominently increased in the periphery of the nodules. 3. Interstitial collagen I and III were not stained in many of the cases with the diffuse GS. With the progression to nodule formation, these were slightly expressed. A lamellar pattern of positive reaction was noted at the periphery of the late nodular lesions. 4. Fibronectin was increased in GBM & MM in the diffuse GS, it was especially intense in the MM. With the progression to the nodule formation, the reactivity of antibody to the fibronectin was decreased. 5. Laminin was weakly stained along the GBM & trace in the MM, but was not changed in the nodular GS. In summary, the expanded mesangial matrix in the diffuse GS showed a markedly increased staining for collagen IV, fibronectin and collagen VI. Less intense linear staining for collagen VI, fibronectin, laminin, collagen IV and collagen III was noted along the GBM. In the nodular GS, the composition of the early nodules resembled that of the diffuse GS. However, the late nodular lesion of the nodular GS revealed decreased reactivity for collagen IV and fibronectin at the periphery of the nodule, where collagen VI and interstitial collagen I and III were increased in laminated pattern.

This is an analysia of 126 cases(14.1%) of segmental vitiligo among 892 vitiligo patient who had visited vitiligo special clinie in Severance Hospital. The results are summarized as follow : 1. There were 53 males(42.1%) and 73 females(57.9%). 2. The mean age of onset was 15.4 years, the mean age on the first visit was 19.3 years, and mean duration of the disease was 4.8 years. 3. Mode of onset was single in 86.5% and the disease was table in 57.1% of patients at the visit. 4. The mean percentage of depigmented lesions was 3.3% and less than 5% of body surface area was involved in 86.5% of patients. 5. The most common site of involvement was head and necl(59.6%), especially face(43.7%) and the trigerminal dermatome was most commonly involved. 6. Poliosis was observed in 39.7%. 7. Family history of vitiligo was obtained in 11.1% of patients. There was no precipitating factors in 126 cases prior to development of vitiligo. 8. Koebner phenomenon was found in 4% of patients. 9. Association with diseases of a proven or suggested allergic or immunologic etiology including atopic dermatitis, halo nevus, uveitis, thyroid disease, lopecia areata and premature graying of hair was found in 10.3% of patients.

Malignant rhabdoid tumor of the kidney(MRTK), an uncommon renal tumor found in children, is one of the most lethal neoplasms of early life. It was first recognized during a review of the first National Wilms' Tumor Study(NWTS) as an extremely aggressive neoplasm whose appearance often mimicks those of skeletal muscle tumors, but without histological, immunohistochemical, and ultrastructural markers of rhabdomyogenesis. Herein we present two cases of malignant rhabdoid tumor of the kidney, one occurring in a 6-month-old male baby, and the other in a 123-month-old girl. They presented a huge tender mass on the left upper quadrant of the abdomen. Microscopically, each case was very cellular and composed of sheets of round or polygonal cells with ample cytoplasm often containing eosinophilic filamentous inclusions and round vesicular nuclei with prominent nucleoli. Case 1 showed lymphomatoid pattern, but case 2 showed foci of several variant patterns associated with classic appearances. The tumor cells showed a strong reactivity for vimentin in both cases. Unusually, case 2 showed focal reactivity for epithelial membrane antigen(EMA), muscle specific actin, and smooth muscle actin. Ultrastructural study confirmed the presence of whorled bundles of intermediate filaments in paranuclear position, and a prominent nucleolus.

OBJECTIVES: The TGF-Beta1 (transforming growth factor-Beta1 ), which has been shown to inhibit cellular proliferation in vitro as a growth regulator, has been demonstrated to enhance tumori-genicity in vivo. The proteolytic processes of cancer are thought to be the crucial point in tumor invasion and metastasis, mainly by matrix metalloproteinases.(MMPs) We investigated the serum TGF-Beta1 and MMP-2 levels in patients with cervical cancer in contrast to those of normal, patients with benign myoma, and cervical intraepithelial neoplasia (CIN). And we questioned whether these serum levels are different according to the therapy of cancer or not. METHODS: We measured serum TGF-Beta1, MMP-2 concentrations by ELISA in 34 patients with cervical cancer, as well as 5 normal volunteers, 14 patients with benign myoma and 23 patients with CIN. Especially in 7 patients with cervical cancer, we measured serum TGF-Beta1, MMP-2 levels before and after therapy. RESULTS: The serum TGF-Beta1 levels in patients with cervical lancer(37.8 +/-15.4pg/ml) were significantly lower than those of the patients with CIN(46.2+/-9.2pg/ml)(p<0.05). But there is no differences among the serum MMP-2 levels in the patients with cervical cancers(680.30+/-116.6pg/ml), CIN(715.2+/-150.0pg/ml), and benign myoma(682.4+/-112.5pg/ml)(p>0.05). Patients undergoing cancer therapy did not have different values of serum TCF-Beta1 and MMP-2 levels as those without cancer therapy.(p>0.05) CONCLUSION: So we suggest that serum TGF-Beta1 may be helpful in differential diagnosing cervical cancers from CIN.
