Langerhans cell histiocytosis(LCH), previously known as histiocytosis X, is rare, proliferative disorder in which the accumulation of pathologic Langerhans cell leads to tissue infiltration and destruction. The jaw is involved 10~20% of all LCH and most common oral symptoms are jaw swelling or a palpation mass. Most of subjects are males and disease appears to start before the age of 10 years. An 11 years old girl was referred from pediatric department. Histological examination confirmed the diagnosis LCH. She was treated intra-lesional injection of corticosteroid. The overall outcome was excellent. After a follow-up period of 20 month, the patient present with no evidence of residual disease on Panoramic view and whole body bone scan. We report this early recognized LCH case treated by corticoid injection in good progress with literature review.

Von Recklinghausen병에 동반되는 악성종양은 주로 신경섬유육종이지만 드물게는 폐암이 동반되는 경우가 보고되고 있고 ras 유전자가 양 질환의 발생에 영향이 있음이 알려져 있어 앞으로 이에 관한 연구가 필요하리라 생각된다.

Although the most commonly encountered orbital tumor is metastatic tumor, adenocarcinoma of stomach metastasized to the optic nerve is rarely reported. The authors discuss a rare case of metastatic adenocarcinoma of left optic nerve with a review of literature. A 44-year-old man presented with decreased visual acuity of left eye for 3 months. Neurologic examination revealed left optic neuropathy. On MR imaging, a homogenously wellenhanced mass surrounding left optic nerve around optic canal was noticed. The X-rays and the whole body bone scan sho-wed multiple bony metastasis. Subtotal removal was performed via combined subfrontal and pterional approach and metastatic adenocarcinoma from the stomach was confirmed histologically. Postoperative course was uneventful, but there was no improvement of visual acuity.

Multiple myeloma is a malignant plasma cell tumor that is thought to originate proliferation of a single clone of abnormal plasma cell resulting production of a whole monoclonal paraprotein. The authors experienced a case of multiple myeloma with severe mandibular osteolytic lesions in 46-year-old female. As a result of careful analysis of clinical, radiological, histopathological features, and laboratory findings, we diagnosed it as multiple myeloma, and the following results were obtained ; 1. Main clinical symptoms were intermittent dull pain on the mandibular body area, abnormal sensation of lip and pain due to the fracture on the right clavicle. 2. Laboratory findings revealed M-spike, reversed serum albumin-globulin ratio, markedly elevated ESR and hypercalcemia. 3. Radiographically, multiple osteolytic punched-out radiolucencies were evident on the skull, zygoma, jaw bones, ribs, clavicle and upper extremities. Enlarged liver and increased uptakes on the lesional sites in RN scan were also observed. 4. Histopathologically, markedly hypercellular marrow with sheets of plasmoblasts and megakaryocytes were also observed.

진단적 I-131 스캔에서 유방의 섭취는 주로 수유 여성에서 보인다고 알려져 있으나 수유 여부와는 관련 없이 나타나는 경우도 보고되어 있다. 갑상선 암으로 갑상선 절제술 후 I-131 치료를 위해 시행한 진단적 스캔에서 유방의 섭취를 보인 환자에서 고프로락틴 혈증에 의한 유류증의 발견 및 이를 근거로한 뇌 단층 촬영상 Empty sella가 진단되어 이를 bromocriptine으로 치료한 후, 유방 섭취의 소실이 확인 되어 I-131 치료를 시행한 경우가 있어 이를 보고하고자 한다.

A 73-year-old man presented with a chief complaint of progressive left knee pain for two months. He had a history of total thyroidectomy and central lymph node dissection due to papillary thyroid carcinoma three months ago. MRI images revealed a solid mass in the left patella. A solid mass demonstrated low signal on T1 weighed image, and high signal on T2 weighed image. And whole body bone scan showed focal photon defect in same lesion of left patella. The histologic result of left knee lesion was adenocarcinoma, consistent with metastatic papillary thyroid carcinoma. Although patellar metastasis of papillary thyroid carcinoma is very rare, when knee pain and radiologic abnormality are noted, differential diagnosis of metastasis is necessary.

갑상선 유두암에 의한 뇌전이는 극히 드물게 발견되어며 그 진단 및 치료방법의 설정이 아직 확립되어 있지 못한 상태이다. 저자들은 갑상선 유두암으로 5년전 갑상선 전절제술을 시술받고 갑상선 호르몬 복용을 하고 있던 24세의 남자에서 간헐적인 발작을 일으킨 전두골내 병소가 갑상선 유두암의 전이에 의한 것임을 조직학적으로 확인할 수 있었다. 이 병소는 전신 요오드 주사상에서는 나타나지 않았지만 Brain CT 및 MRI 소견으로만 병변의 진단이 가능하였으며 stereotactic cranitomy에 의한 종양제거로 비교적 만족스러운 결과를 얻어 현재 밀착추적중에 있다.

During image-guided radiation therapy, the patient is exposed to unwanted radiation from imaging devices built into the medical LINAC. In the present study, the effective dose delivered to a patient from a cone beam computed tomography (CBCT) machine was measured. Absorbed doses in specific organs listed in ICRP Publication 103 were measured with glass dosimeters calibrated with kilovolt (kV) X-rays using a whole body physical phantom for typical radiotherapy sites, including the head and neck, chest, and pelvis. The effective dose per scan for the head and neck, chest, and pelvis were $3.37{\pm}0.29$, $7.36{\pm}0.33$, and $4.09{\pm}0.29$ mSv, respectively. The results highlight the importance of the compensation of treatment dose by managing imaging dose.

Anaplastic carcinoma of thyroid gland account for no more than 10% of thyroid cancer, but it shows extremely poor prognosis. The purpose of this study is to review the outcome of patients with anaplastic carcinoma over the span of 5 years and to determine the patterns of clinical presentation, age, sex and other possible prognostic variables. We analyzed 30 cases of anaplastic carcinoma retrospectively from 1991 to 1995. There were 14 men and 16 women. There age ranged 33 to 75 years with a mean of 61.0 years. Sixteen patients presented with transformationqr of well differentiated carcinoma to anaplastic carcinoma, 1 with rapid in-crease in the size of long standing goiter, 8 with rapidly growing neck mass and 4 with meta static disease. Twenty-eight patients(93.3%) showed cervical lymphnode metastasis at presentation and twenty three patients(76.6%) showed laryngotracheal invasion. Nine patients (30.3%) showed distant metastasis. Treatment modalities included surgical resection, external irradiation, radioactive iodine and systemic chemotherapy. At decision making of treatment plan, we considered completeness of initial surgery, uptake rate of whole body radioactive io-dine scan, locoregional progression and distant metastasis. The median survival was 6.8 months and three cases survived beyond 12 months.

The patient a 24-year-old male, was shown to have milliary shadows on chest radiographs from the age of 20. He was temporarily treated for pulmonary tuberculosis without success. He had left thyroid mass and lymph node metastases in neck CT scan which was taken after admission but fine needle aspiration result in scanty cellularity. He underwent total thyroidectomy with left modified radical neck dissection and right selective neck dissection under the impression of differentiated thyroid cancer with bilateral neck metastases. Then he underwent 131I ablation treatment and postoperative whole body 131I scintigraphy revealed diffuse intensive uptake in the bilateral lung fields, demonstrating that the pulmonary lesions were metastases of the thyroid cancer.
