Lymphangiomas are relatively rare benign tumors of the lymphatic system, characterized by congenital lymphatic malformation such as anastomosis or obstuction of the lymphatic channels. There are most frequently diagnosed in children younger than 3years. In contrast to that of the hemangioma, the sex distribution of the lymphangioma is nearly evenly divided. The head and neck lymphangioma represents about $70{\sim}75%$ of all lymphangiomas, and they are difficult to manage. Spontaneous regression is rare, and rapid intermittent enlargement occurs secondary to infection or trauma. Enlargement may cause serious sequelae such as airway obstruction, feeding difficulties, and cosmetic problems. Treatments previously used for lymphangiomas include surgical excision and intralesional injection of sclerosants. Problems associated with surgical excision include the risk of cosmetically unacceptable scarring and the risk of damage to surrounding vital stricture and the high risk of incomplete excision. The sclerosants previously used have numerous other local and systemic side effects. This report describes a case that was successfully treated using OK-432 as a new sclerosant drug and secondary surgical excision for congential cavenous lymphangioma extensively enlarged to tongue, mouth floor and submandibular region.

The incidence of lung cancer and its mortality rate are increasing in Korea. At the time of diagnosis, 40% patients of lung cancer patients had metastatic lesions. The common metastatic sites are the contralateral lung, bone, liver, adrenal gland and the brain. Metastasis to oral mucosa is rarely encountered in lung cancer and metastasis to the gingiva is more uncommon. Approximately 1% of malignant carcinomas in the oral cavity are the result of metastases, and 10-25% of metastatic cancers originate from lung cancer. Clinically metastatic gingival lesions are benign including hemangioma, pyogenic granuloma, giant-cell granuloma or a peripheral fibroma. Often metastases to the gingiva are diagnosed too late and by the time they are detected, they have metastases to other organs. Here we report a case of small cell lung carcinoma that had metastased to the gingiva with review of relevant literature.

Object When angiogenesis is excessive, Cancer, RA, Blindness, Psoriasis, Hemangioma, Diabetic retinopathy, Granulation, etc are induced. On the contrary, when it is insufficient, Stroke, Heart disease, Ulcer, Infertility, Scleroderma, artherosclerosis, delay of the wound recovery, etc occur. In recently, the methods which is control of abnormal angiogenesis are researching actively in relathion to anticancer research. This study is search for effective drugs which suppress this angiogenesis, in the ingredients of the herbs that invigorate and dispel blood stasis using to treat intravascular coagulation in the oriental herbal medicine. Methods We maked 80 % methanole extracts of Cnidii Rhizoma, Olibanum, Myrrha, Corydalidis Tuber, Curcumae Radix, Curcumae longe Rhizoma, Zedoariae Rhizoma, Salviae miltiorrhizae Radix, Polygoni cuspidati Rhizoama, Leonuri Herba, Persicae Semen, Carthami Flos, Trogopterorum Faeces, Achyranthis Bidentatae Radix, Manitis Squama, Eupolyphaga, Hirudo, Tabanus, Lycopi Herba, Artemisiae anomalae herba, Vaccariae Semen, Sappan Lignum, Gleditsiae Spina, Draconis Resina, Leonunari Semen, Selaginelliae Folium, Spatholobi Caulis, and these extracts were tested for MTT viabilaty test, BrdU incorporation, Tube foramtion assay on ECV304(immotalized human umbilical vein endothelial cell) at the concentration of $50{\mu}g/ml$, $100{\mu}g/ml$, $200{\mu}g/ml$, $400{\mu}g/ml$ Results All extracts except Draconis Resina have no cytotoxicity at the $100{\mu}g/ml$, and in BrdU incorporation test, proliferation rate were reduced below 60% at the concentaraion of $100{\mu}g/ml$ by Zedoariae Rhizoma, Sappan, Lignum Gleditsiae, Spina Draconis Resina Vaccariae Semen.

Purpose : To compare Multi Echo Data Image Combination (MEDIC) and fast SE T2-weighted images with fat saturation (T2FS) to suggest more accurate evaluation of the histologic components of soft-tissue tumors. Materials and Methods : The experimental group included 25 histologic tissues (5 vascular, 4 neural, 4 fibrous, 4 hypercellular, 2 hemorrhagic necroses, 2 cystic, 2 lipoid, 1 myxoid stroma, and 1 thrombus) in 10 patients who had pathologically confirmed schwannoma (n = 3), hemangioma (n = 2), lipoma (n = 1), angiokeratoma (n = 1), synovial sarcoma (n = 1), liposarcoma (n = 1), and malignant fibrous histiocytoma (n = 1). The inhomogeneity values were measured using the standard deviation value (SD) divided by the mean value as SD presents an error amount similar to that of imaging heterogeneity. Results : The inhomogeneity values of 25 histologic components were lower on MEDIC than those on T2FS (p < .001). Conclusion : We conclude that MEDIC is more accurate than T2FS for evaluating the tissue components of soft-tissue tumors using digitalized data because MEDIC images have far lower inhomogeneity.

Purpose: Benign bone tumor of the talar body have rarely been evaluated according to the therapeutic methods because of the scarcity of their incidence. Here, we report our experience of 8 cases who were treated by using of posterior approach and curettage through the posterior process of the talus. Materials and Methods: Between February 1986 and October 2001, we experienced 8 cases of benign bone tumor occurring in the talar body. They included two osteoid osteomas, two giant cell tumors, one capillary hemangioma, one chondroblastoma, one simple bone cyst, and one osteochondroma. Their mean age was 22.1 years (ranging from 10 to 41 years). Mean follow-up period was 7.7 years (ranging from 1 to 16 years). All patients were treated by using of posterior approach. Two osteoid osteomas and one osteochondroma were treated by excision of tumors. Other cases were treated with curettage through the cortical window on the posterior process of the talus. Results: There was no recurrence during the follow-up period. one infection occurred. Except this case, all patients had no pain in weight-bearing, and complete range of movement at the ankle joint was reserved in each case. Conclusion: In this study, we suppose that posterior approach to the talar body may be a safe method with minimal damage of normal tissues and sufficient of curettage is capable through the cortical window on the posterior process of the talus.

Kimura's Disease is a chronic inflammatory and proliferative condition producing subcutaneous masses especially in the head and neck area. This report of our experience with 5 patients with this disease is the first in the Korean surgical literature. Kimura's Disease is thought to be part of the larger spectrum of the entity known as angiolymphoid hyperplasia with eosinophilia (ALHE). It is characterized pathologically by hyperplastic lymphoid follicles, eosinophilic infiltration, and vase 비 ar proliferation. It produces masses which are most common in the area of the parotid, submandibular gland and upper neck. These masses occupy the subcutaneous tissues but also extend into salivary tissue and into upper neck nodes. One of our patients had masses in the groin. The tumors are extremely vascular due to the presence of new proliferative vessels and sinusoids. The average age of our 5 patients was 35, but all but one case were younger than 38 years of age. The male: female ratio was 3 : 2, and the average duration of symptoms was 5,2years. All patients had peripheral blood eosinophilia. All had multiple masses, sometimes symmetrical. The management was surgery alone in one case, surgery and steroids in one case, surgery and radiotherapy in two cases, and all three modalities in one case. The relationship of this entity to ALHE and our experience in the management of this disease are presented. A clinicopathological discrepancy alerted us to the existence of Kimura's Disease. A nineteen-year old male presented with subcutaneous masses over both mastoid areas present for 3 years (Case III). When biopsy on each side was reported as 'eosinophilic granuloma' we submitted the slides to an internationally expert pathologist. Symmetrically occurring tumors in the peri-parotid subcutaneous areas did not fit any category of neoplasm or granuloma known to us. The diagnosis, made by Dr. Gist Fan at the Ochsner Clinic, was Kimura's Disease. We found two additional cases in a review of soft tissue eosinophilic granuloma previously reported at Presbyterian Medical Center, and since then have diagnosed two new cases. These five cases constitute the basis for this, the largest series to be reported in Korea. These vascular, tumor-like lesions of the skin, subcutaneous areas and subjacent structures of the head and neck have been a variety of names, such as angiolymphoid hyperplasia with eosinophilia, eosinophilic hyperplastic lymphogranuloma, angioblastic lymphoid hyperplasia with eosinophilia, histioid hemangioma, and epithelioid hemangioma. The history of this disease spectrum dates back to 1937 when Kimm and Szeto (1) reported 7 cases of 'eosinophilic hyperplastic lymphogranuloma' in the Proceedings of the Chinese Medical Journal. In 1948 Kimura and his associates(2) reported additional cases in Japan under the title 'On the unusual granulation combined with hyperplastic changes of lymphatic tissue.' From then until 1966 several hundred cases were reported in China and Japan. The first report from the West was by Wells and Whimster(3) in the British Journal of Dermatology, in 1969. These authors coined the term, angiolymphoid hyperplasia with eosinophilia (ALHE). Since that time a debate has ensued as to whether Kimura's Disease and ALHE are distinct entities, or whether Kimura's is part of the larger spectrum of ALHE, perhaps a later or advanced phase. From the clinical perspective, surgeons should be aware of the diagnosis of Kimura's Disease not only as part of the differential diagnosis of head and neck tumors but also because these lesions are indolent, and generally require conservative surgical removal as part of the management program. CASE I. A 37-year-old female company employee presented in August 1982 with submental swelling of 12 years' duration and with inguinal swelling of 7 years' duration. The submental mass measured 5x5cm. and the inguinal mass was 8x4cm. in size. Peripheral eosinophilia varying from 14% to 40% was found. On August 20, 1982, the submental mass was removed and a superficial groin dissection was done. In May 1983 an intraoral lesion of the palate was removed. The patient is free of disease. CASE II. A 23-year-old unemployed man visited this hospital for the first time in July, 1984, with swelling of the right cheek present for 6 years. The mass was soft and ill-defined but measured 10x20cm. and extended from the submandibular upper neck to the zygomatic arch, and from the mastoid to the cheek, over the parotid gland. Eosinophilia varying from 27% to 29% was noted in the peripheral blood. On March 21, 1986, the lesion was resected. The procedure comprised an extended superficial parotidectomy from the temporalis fascia to the upper neck. Post-operatively radiotherapy 3000 rad tissue dose was administered using the 6 MeV linear accelerator. The patient remains free of disease. CASE III. A 19-year-old student came to the clinic with masses over both mastoid areas, present 3 years. On the right there were two adjacent lesions, one over the mastoid, the other in the upper jugular level of the neck. On the left it was a single mass over the mastoid. Eosinophilia varied from 13 to 32% in the peripheral blood, and 11.6% in the bone marrow. Incisional biopsy revealed 'eosinophilic granuloma' and a trial of predisolone was employed. The mass increased in size so a small dose of radiation (600 rads) was used, with substantial regression,. The lesion on the left was excised and follwed by 1000 rads radiotherapy. Finally recurrent tumor on the right side was removed on November 5, 1985. The patient remains free of disease. CASE N. A 29-year-old local merchant had had swelling of both upper necks since childhood. At the time of his first visit on March 17, 1986, the right submandibular mass measured 5x3.5cm. and the ,right upper neck and parotid tail mass measured 2.5cm. On the left there were masses in the upper neck, the largest of which measured 2.5cm, and of the parotid tail, 2.0cm. in size.(See Fig. 1) Peripheral eosinophilia of 39% was recorded. Left side partial parotidectomy and resection of the upper neck and subdigstric mases was done on May 2, 1986. The mass involving the right parotid tail and upper neck nodes was removed on Angust 7,1986. Postoperatively the patient was placed on prednisolone 30 mg. per day. No definite masses are palpable. CASE V. A 66-year-old housewife informed us, at the time of her first visit in May, 1986, that she had had multiple neck masses since 10 years ago. On the right side there was a 2.5cm. subcutaneous mass of the upper neck, over the upper jugular chain. On the left there was a 9x4.5cm. mass involving the entire parotid, the post-auricular area and the upper neck. A third mass presented in the submental area and measured 3.5cm. (See Fig. 2) Eosinophilia of 51% was noted in the peripheral blood. partial excision of the left upper neck lesion and complete excision of the submental mass were performed on june 6, 1986. post-operatively she was placed on 20 mg. of prednisolone daily, but when the mass re-grew after two months she was referred to Radiation Therapy for a 2500 rad course of treatment. A barely palpable thickening remains.

The aim of this retrospective study was to determine whether a nephron sparing surgery might be feasible in patients with a small solid renal tumor. Materials and methods: Between 1988 and 1999, 21 patients with a radiologically detectable small solid renal tumor underwent enucleoresection, wedge resection and polar segmental nephrectomy. The mean age of the 11 men and 10 women in this study was 43 years (range 14 to 68). According to the preoperative radiological diagnosis, 15 among the 21 patients were considered to have renal cell carcinoma, 4 were considered to have angiomyolipoma, and in the remaining 2 patients, radiological differentiation of renal tumors was difficult. Among 15 patients considered to have renal cell carcinoma, 14 were found to have renal cell carcinoma and the remaining one patient was diagnosed as having oncocytoma on pathologic examination. Radiological determination of angiomyolipoma in four patients was confirmed to be correct on pathological examination. The 2 patients whose radiological diagnose was difficult were found to have cavernous hemangioma and angiomyolipoma. One patient with renal cell carcinoma developed arteriocaliceal fistula, the only immediate complication in this series and underwent nephrectomy on postoperative 10th day. The mean follow up duration for the 14 patients with renal cell carcinoma was 18.6 months (range:1-103). There was no other tumor involvement in the resection margins following the nephron sparing surgery. These results suggest that nephron sparing surgery provides an effective treatment for patients with a single, small, unilateral, localized renal tumor. Longer follow-up is suggested for more definite verification of the role of nephron sparing surgery.
