The involvement in the spine of eosinophilic granuloma is not common. Especially, involvement of cervical spine and posterior neural arch is quite rare. In addition, radiographic findings including magnetic resonance images of eosinophilic granuloma are manifested as vertebral body collapse, loss of pedicle and paravertebral soft mass formation; it must be differentiated with other conditions, such as malignant bone tumor, metastatic cancer or tuberculous spondylitis. We experienced three cases of eosinophilic granuloma involving posterior neural arch of C4, C7, and body of C4 respectively, which were performed surgical treatment and achieved complete healing. We report these cases with review of literatures.

Langerhans cell histiocytosis (LCH), previously called histiocytosis X, refers to a spectrum of disease characterized by idiopathic proliferation of histiocytes producing focal or systemic manifestations. Causes and pathogenesis remain unclear The basic histopatholgic fndings are identical in the three well-established clinical syndromes (eosinophilic granuloma, Hand-Shuller-Christian disease, Letterer-Siwe disease). The disease has a predilection for children, although it may occur in adults. We experienced two cases of adult onset Langerhans cell histiocytosis in the ribs. One case was associated with diabetes insipidus and the other case had a solitary lesion.

Pulmonary eosinophilic granuloma or histiocytosis X is a chronic interstitial lung disease characterized by proliferations of Langerhans cells and, therefore, not truly histiocytosis. Both histiocytes and Langerhans cells are believed to be related to the mononuclear phagocyte system. In Eosinophilic granuloma, extra-pulmonary such as mediastinal or hilar lymph nodes involvement is very rare in adult. We report a case of young man with eosinophilic granuloma involving lung and anterior mediastinal lymph node simultaneously which is confirmed by open thoracotomy.

Pulmonary eosinophilic granuloma, a rare form of Langerhans cell histiocytosis confined to lung, has no known etiology and variable natural history. It is characterized by discrete proliferation of Langerhans cells. It is known that over 90% of the patients are cigarette smokers, and it is rarely reported in non- or passive-smoking patients, especially female. Here we describe a case of pulmonary eosinophilic granuloma in a passive-smoking, reproductive female patient presented with spontaneous pneumothorax. We identified S-100 and CDla positive histiocytes on immunohistochemical stain of the lung tissue obtained by open lung biopsy.

Background : Transforming growth factor-$\beta$(TGF-$\beta$) may play a role in a variety of fibroproliferative disorders including pulmonary fibrosis via the induction of extracellular matrix accumulation. TGF-$\beta$ not only stimulates extracellular matrix production, but also decreases matrix degradation. Interstial lung diseases have demonstrated marked expression of TGF-$\beta$. Methods : To evaluate the possible role of TGF-$\beta$ in human pulmonary fibrosis, by using neutralizing antibody of TGF-$\beta$ we investigated immunohistochemically the expression of TGF-$\beta$ in the formalin-fixed, paraffin-embedded tissue sections of the 5 normal cases for the control, and a couple of pieces of tissues taken out of 3 cases with idiopathic pulmonary fibrosis, 3 cases with ILD from bleomycin toxicity, 3 cases with ILD from sarcoidosis, and 3 cases with ILD from eosinophilic granuloma. Results : In the 5 normal cases for the control, the TGF-$\beta$ was expressed in bronchial and alveolar epithelial cells. Up-regulation of the TGF-$\beta$ expression was showed in the interstitial fibroblast cells of alveolar septa in 5 pieces and proliferated alveolar pneumocytes in 1 piece among 6 pieces tissues taken out of 3 cases with idiopathic pulmonary fibrosis. Also up-regulation of the TGF-$\beta$ expression was showed in alveolar lining pneumocytes, intra-alveolar mononuclear cells, and epithelioid cells in most of cases of ILD from bleomycin toxicity, sarcoidosis and eosinophilic granuloma. Conclusion : These findings suggest that up-regulation of the TGF-$\beta$are involved in pathogenesis of interstitial lung fibrosis from variety of causes.

Eosinophilic granuloma (histiocytosis $\times$) is an uncommon granulomatous disorder affecting the mononuclear phagocytic cell system caused by unknown etiology. When confined to the lungs, it is also known as pulmonary eosinophilic granuloma or pulmonary histiocytosis $\times$. After the first case was described in 1951 by Farinacci et ai, more 250 cases were reported in the English literature. However only 4 cases has been introduced in our country. We describe two additional cases. In both cases, open lung biopsies are performed for definite diagnosis and examined by immunohistochemical stain for S-100 protein and electron microscopy for ultrastructural identification of Birbeck granule.

One dog and a cat with a history of diarrhea, anorexia and depression were referred. They showed normal laboratory examination results. Radiographic findings included a mid abdominal mass with ill-defined margin and serosal detail loss of peritoneal space. On abdominal ultrasonography, the round mass with heterogenous parenchymal echogenicty with irregular contour was found. It revealed as inflammation through ultrasound guide fine needle aspiration. After surgical removal of the masses in both cases, the clinical signs were resolved and focal pyogranuloma was confirmed through histopathologic examinations.

Purpose : Eosinophilic granuloma is a rare benign tumor that is characterized histologically by the presence of destructive granulomas containing numerous Langerhans, cells. The most common presentation of eosinophilic granuloma is a painful, immobile scalp mass in the frontal and parietal bones occurring predominantly in children and adolescents or young adults. We report a representative case of eosinophilic granuloma. Methods : A 16-year-old woman complained of an enlarging fixed scalp mass without pain and tenderness which measured $3{\times}4.5cm$ at the frontal area, which had been found incidentally 2 months before. Plain skull x-ray showed a punched-out bone lesion. Computed tomography and magnetic resonance imaging showed a non-enhancing osteolytic lesion. The tumor and surrounding bony edges were completely removed via a bicoronal approach. The bony defect was reconstructed with bone cement. Results : The tumor was involved frontal bone and dura mater. We confirmed the tumor by the documentation of Birbeck's granules by electron microscopy. There is no evidence of local recurrence during postoperative 1.5 years. Conclusion : The present case shows the characteristic feature of frontal bone involvment of the eosinophilic granuloma. The prognosis of eosinophilic granuloma depend on age at diagnosis and number of bones involved. We consider that best choice of treatment for eosinophilic granuloma is surgical excision.

Schistosomiasis is a snail-transmitted trematodiasis acquired by immersion in water which contains the cercariae. In Korea, six imported cases of urinary schistosomiasis by Schistosomc haematobium and one case of imported cerebral schistosomiasis by S. mansoni were reported. Herein we report a case of S. monsoni infecting rectum of a 46 year-old Korean male, who had been to Saudi Arabia for two years. On colonoscopy for routine physical check up, a 0.4 cm polyp in the rectum was detected and biopsy was done. Microscopically, rectal mucosa showed several granulomas which were composed of macrophages, Iymphocytes, neutrophils and eosinophils. The center of each granuloma showed an ovoid egg often containing miracidium. The eggs measured 130 × 60 ㎛ in average size. They had yellowish-brown transparent shell loth the characteristic lateral spille. This is the 8th imported case of schistosomiasis in Korea and the second one infected by S. mansoni. Key words: Schistosomc mansoni, rectum, Korea, imported case.

Purpose: We evaluate the results of treatment of pathologic femur fractures secondary to bone tumors in children. Materials and Methods: Between January 1995 and June 2004, 18 patients(20 cases) were evaluated. Their mean age of the first episode of fracture was 10.2 years and mean follow-up period is 42.5 months. Primary bone tumors, the location of fracture, time to union and complications were evauated. Results: Fractures occurred at proximal portion in 14 cases, shaft 3 cases and distal portion 3 cases. The bone tumors causing pathologic fracture were fibrous dysplasia(9 c ases), simple bone cyst(4 cases), aneurysmal bone cyst(4 cases), nonossifying fibroma(2 cases) and eosinophilic granuloma(1 case). In the treatment for fractures, cast was in 11 cases, internal fixation 8 cases and external fixation in 1 case. In the treatment for tumors, observation was in 11 cases, curettage & bone graft in 8 cases and resection in 1 case. In polyostotic fibrous dysplasia, all cases were treated by cast initially but deformity developed in all cases. Fracture prevention and deformity correction were obtained with intramedullary nailing. Conclusion: Adequate choice of treatment of bone tumor and fracture will result in good prognosis.
