A 69-year-old man presented with annular lichen planus involving both forearms, hand dorsa, wrists, inner sides of the thighs, knees and ankles. He was treated initially with systemic corticosteroids and etretinate, but rernission and recurr ence of the skin lesions were observed. During the follow-up, we found erythrasma on all his toewebs and both soles. After administration of erythromycin for the treatment of erythrasma, lesions of the lichen planus rapidly improved. Five months later, some lesions of lihen planus and erythrasma had recurred. After administration of erythromycin, the lesions of lichen planus improved again. No recurrence was observed for the following 8 months. We suspect that eradication of the chronic focus of infection and the anti-inflammatory effect, of erythromycin may lead to supression of abnormal immunological reactions and resolution of lichen planus.

Most of the malignant tumors of the pancreas are adenocarcinomas arising from the ductal epithelium. Primary leiomyosarcoma of the pancreas, even though it is the most common sarcoma of the pancreas, is very rare. We present a case of leiomyosarcoma of the pancreas, probably primary, with metastases to the stomach, lymph nodes, and abdominal wall. A 52-year-old woman visited the hospital with vague right upper abdominal pain and weigh loss of 6 kg for 2 months. The radiological and endoscopic examination revealed that she had a large heterogeneous mass, 11 cm in size, in the pancreatic body and tail, a 4 cm-sized mass in the paraaortic area, and a 3 cm-sized polypoid mass in the stomach. Histologically, they were all similar to one another and composed of markedly pleomorphic cells. Immunohistochemical and electron microscopic studies showed definite smooth muscle differentiation of the tumor cells. Two months later, the patient underwent an excision of a new 3 cm mass in the right lower abdominal wall, showing features of well differentiated leiomyosarcoma.

Fibrous dysplasia in the orbit and cranial base may involve the optic canal. Although fibrous dysplasia is benign, it may produce a mass effect along the course of the optic nerve which can then induce visual disturbance as well as contour deformities of the skull and facial bone. The treatment of fibrous dysplasia in the orbit and cranial base is to resect the lesion as much as possible and then reconstruct immediately. As well, if there is any evidence of optic canal involvement and disease progression, the treatment of fibrous dysplasia may include optic nerve decompression. It is generally understood that some patients experience improvement of visual function after optic nerve decompression. We performed radical excision and reconstruction by means of autogenous calvarial bone graft and methylmethacrylate in 7 cases. The autogenous calvarial bone was used to reconstruct the orbit. The methylmethacrylate was used to reconstruct bony defect in the temporal area. The orbit was reconstruced into one block which was made of autogenous calvarial bone with a microplate and screw. This method is superior compared to the previous multifragment wiring method with regard to stability, operation time, and appearance. The patients in our series showed satisfactory appearance. In 6 cases, we performed optic nerve decompression. Therapeutic optic nerve decompression was done in 3 cases and prophylatic optic nerve decompression was done in the others. Following therapeutic optic nerve decompression, visual acuity was improved in 2 cases while the others showed a decrease in visual acuity. There was no change of visual acuity and visual field in 1 case after prophylactic optic nerve decompression. However, the others showed decrements in visual acuity or visual field. Therefore, we believe that more attention should be paid during optic nerve decompression procedure and strict indications to that procedure should be applied.

The tuberculous infection of the skeletal system especially, tuberculous spondylitis is frequently encountered with orthopedic fields. Up to date, Various methods of the treatment are present but each method has problems. Recently, as a development of the microsurgical instrumentation and surgical technique, we had been tried to the two patients of tuberculous spondylitis by vascularized fibular bone graft and anterior fusion. The advantages were as follows; 1. Shortened the bony union times by this operative method. 2. Earlier returning to the social activities compared to the ordinary method. 3. The children involved tuberculous spondylitis with severe kyphosis, who can be corrected the severe kyphosis by this operative method. 4. We can be obtained the rigid graft bone fixation with adequate length of bone by this operative method.

Spontaneous pneumothorax is a known, but relatively rare complication of pulmonary metastases of sarcoma. A 19-year-old man was presented with chest pain and dyspnea for three days and was diagnosed as left pneumothorax. After bleb resection, microscopic examination revealed metastatic osteosarcoma forming subpleural fistula and dystrophic calcification. Four years ago, he had had limb salvage operation and chemotherapy for osteosarcoma of left femur. After two and a half years he had a bleb resection for right pneumothorax without any evidence of metastasis. Six months later, he was found to have a 4x3cm sized lung mass in the right lower lobe. After lobectomy, he was diagnosed as pulmonary metastasis of osteosarcoma. Pneumothorax is the common complication of metastatic osteosarcoma to the lung and it may be presented before the pulmonary metastasis is clinically evident. It is important to recognize a pneumothorax of the patients with osteosarcoma as a possible sign of metastases.

The term 'primary melanocytic neoplasm' covers a wide disease spectrum, from well differentiated meningeal melanocytoma to malignant melanoma, its most aggressive malignant counterpart. Previous reports have shown that due to the paramagnetic effect of melanin, melanocytic neoplasms show high signal intensity on T1-weighted images and very low signal intensity on T2-weighted images, with relatively homogeneous contrast enhancement. The differentiation of leptomeningeal malignant melanoma from benign melanocytoma is important because of their different prognosis but on the basis of imaging findings alone is difficult. Ultrastructural immunohistochemical analysis is a possible alternative. We report the imaging findings of rare primary malignant melanoma, revealed by noncontrast-enhanced CT as a high-density mass, and demonstrating high signal intensity on T1-weighted images, and very low signal intensity on T2WI, with relatively good contrast enhancement.
