에이즈 환자에게서 흔히 나타나는 구강 내 병변은 충치, 구강칸디다증, 구강 모상 백반증(oral hairy leukoplakia),재발성 아프타성 구내염(recurrent aphthous stomatitis),재발성 포진성 구내염(recurrent herpetic stomatitis),치주염, 카포시 육종, 비호치킨성 림프종 등이다. 이 중 에이즈 환자에게 비교적 특징적인 병변은 구강 칸디다증, 입안털백색판증, 카포시 육종 등이지만 일반인들에서 흔히 관찰되는 충치라고 하더라도 치주염이나 농양으로 빠르게 진행한다면 에이즈를 의심해 보아야 하며, 반복적인 아프타성 궤양이나 포진성 궤양이 유달리 크고 오래 지속된다면 역시 에이즈의 가능성을 생각해 봐야 한다. 구강 병소는 에이즈 환자에게서 흔히 발견되며 이 질환의 초기 상태를 제시할 수 있다는데 의의가 있다.

Kaposi's sarcoma (KS) is a multicentric human immunodeficiency virus-associated neoplasm characterized by multiple vascular nodules in the skin, mucous membranes, and viscera. Gastrointestinal acquired immunodeficiency syndrome (AIDS)-related KS is the most common visceral involvement reported in disseminated disease. Here, we present the findings of a rare case of KS involving multiple organs with abdominal pain and active bleeding in the colon. Multiple intraluminal lesions were found in the terminal ileum, sigmoid colon, and rectum by ileocolonoscopy, and in the jejunum and ileum by fluoroscopy. Abdominopelvic CT revealed multiple enhanced flat lesions in the ileum and enlarged lymph nodes. The diagnosis was confirmed by histopathology, and antiretroviral therapy was initiated as the treatment of choice for KS. Owing to the increasing number of AIDS patients, it is essential for radiologists and clinicians to be aware of the imaging characteristics of KS to protect physicians from indiscriminate exposure to AIDS.

Kaposi's sarcoma was first descrided by Kaposi in 1872 as an idiopathic multiple hemorrhagic sarcoma. Its clinical features revealed to be erythematous red or purple macule started out, and developing into palpable dome-shaped nodules. Etiology is not defined to detail at present. Kaposi's sarcoma is classified to 4 categories; Classical, African, Epidemic and Transplant type. Epidemic or AIDS categories is found approximately 20 % of all AIDS and has strong predilection for head and neck region. The first case of Kaposi's sarcoma observed in patients with kidney transplants was reported in 1969. Kaposi's sarcoma now accounts for 5% of all tumors associated with transplanted patients and alteration of the immunosuppression may have played a key role in these recipients. The most common site of Kaposi's sarcoma in transplanted patients are extremities but rare in head and neck area. We report a case of Kaposi's sarcoma on the hard palate in the kidney transplantation patient.

AIDS란 성적 접촉에 의하여 사람에서 사람에게로 전염되었거나 금지된 마약이나 각성제등의 정맥주사에 쓰이는 주사기나 주사침을 공용하여 전염되는 것이 주인 감염경로에 의하여 일어나는 일련의 병의 최종적인 상태를 말한다. 1981년6월5일자 MMWR지에 실린 미국 로스엔젤레스지역 5명의 남성동성애자에 발생된 카리니폐염의 보고가 첫 보고증예이나, 이보다 앞선 2년반사이에 미국의 뉴욕주와 캘리포니아주에서 남성동성애자에서 카포시육종이나 카리니폐염환자가 발생되었었음이 알려져 이 병이 주목받게 되었다.

Its clinical features revealed to be erythematous red or purple macule started out, and developing into palpable dome-shaped nodules. Etiology is not defined to detail at present. Kaposi's sarcoma is classified to 4 categories; Classical, African, Epidemic and Immunosuppressive type. Epidemic categories is found approximately 20% of all AIDS patients and has strong predilection for head and neck region. The first case of immunosuppresive type Kaposi's sarcoma in patients with kidney transplants was reported in 1969. Kaposi's sarcoma accounts for 5% of all tumors associated with transplanted patients. The most common site of Kaposi's sarcoma in immunosuppressed patients are extremities, but rare in head and neck area. A 42 years old woman who had systemic lupus erythematosus visited to our clinic because of gingival hyperplasia, and excisional biopsy revealed Kaposi's sarcoma. We experienced a case of favorable results using excision and chemotherapy, so we report with review of literatures.

Purpose: We designed a water-based bolus device for radiation therapy in Kaposi's sarcoma. This study evaluated the usefulness of this new device and compared it with the currently used rice-based bolus. Materials and Methods: We fashioned a polystyrene box and cut a hole in order to insert patient's extremities while the patient was in the supine position. We used a vacuum-vinyl based polymer to reduce water leakage. Next, we eliminated air using a vacuum pump and a vacuum valve to reduce the air gap between the water and extremities in the vacuum-vinyl box. We performed CT scans to evaluate the density difference of the fabricated water-based bolus device when the device in which the rice-based bolus was placed directly, the rice-based bolus with polymer-vinyl packed rice, and the water were all put in. We analyzed the density change with the air gap volume using a planning system. In addition, we measured the homogeneity and dose in the low-extremities phantom, attached to six TLD, and wrapped film exposed in parallel-opposite fields with the LINAC under the same conditions as the set-up of the CT-simulator. Results: The density value of the rice-based bolus with the rice put in directly was 14% lower than that of the water-based bolus. Moreover, the value of the other experiments in the rice-based bolus with the polymer-vinyl packed rice showed an 18% reduction in density. The analysis of the EDR2 film revealed that the water-based bolus shows a more homogeneous dose plan, which was superior by $4{\sim}4.4%$ to the rice-base bolus. The mean TLD readings of the rice-based bolus, with the rice put directly into the polystyrene box had a 3.4% higher density value. Moreover, the density value in the case of the rice-based bolus with polymer-vinyl packed rice had a 4.3% higher reading compared to the water-based bolus. Conclusion: Our custom-made water-based bolus device increases the accuracy of the set-up by confirming the treatment field. It also improves the accuracy of the therapy owing to the reduction of the air gap using a vacuum pump and a vacuum valve. This set-up represents a promising alternative device for delivering a homogenous dose to the target volume.

많은 사람들이 에이즈의 첫 증상하면 붉은 반점을 흔하게 떠올리게 된다. 사실 이것은 에이즈 전구 증상이 아니고 사람면역결핍바이러스(HIV)에 감염되고 8-10년간의 무증상기를 거친 후에 인체의 면역기능이 바닥까지 망가졌을 때에 생기는 카포시 육종이라는 질병이다. HIV에 감염된 후에 면역기능이 파괴되면 본래 정상인에게 병을 일으키지 않는 미생물에 의해서 감염증이 생기고(이를 기회감염이라고 함)암도 발생하게 된다. 이와 같이 HIV 감염인에게 기회감염 혹은 암 등이 발생한 상태를 에이즈라고 한다. 어떤 사람들은 HIV에 감염된 후에 에이즈가 발병하기 전까지 아무런 증상을 느끼지 못하지만 일부는 에이즈 발병 전에 여러 가지 증상들(에이즈 전구 증상)을 겪게 된다. 오늘은 HIV에 감염된 후 에이즈가 발병하기 전에 발생할 수 있는 전구 증상들에 대해 알아보고자 한다.

There are several oral lesions related with AIDS, such as candidiasis, hairy leukoplakia, Kaposi's sarcoma, aphthous stomatitis, lichen planus, and other opportunistic infectious diseases. Among the others, Kaposi's sarcoma, the most common malignant tumor associated with AIDS, is closely linked to the number of CD4+ T cell. Kaposi's sarcoma often occurs in palate, the most prone site, and has characteristic clinical features in most cases. Sometimes, the tumor induces underlying bone destruction at late stage. We report a case of a 27 year-old man with AIDS-associated Kaposi's sarcoma at left lower retromolar triangle, parapharyngeal area and discuss the management of AIDS patients in dentistry.

Microvenular hemangioma (MVH) is a rare acquired benign vascular neoplasm, which presents commonly as a solitary purple-to-red nodule or plaque measuring approximately 10 mm in diameter. MVH occurs primarily on the extremities or the trunk. Most lesions are solitary, and multiple lesions are rare. Histopathological features of MVH include numerous, scattered, thin and irregularly branching small vessels in the dermis and endothelial cells without atypia. Owing to similarities in clinical morphology and histopathological features, MVH may often be indistinguishable from the early patch stage of Kaposi sarcoma. Immunohistochemical (IHC) analysis helps differentiate between the 2 diseases. The results of IHC tests in patients with MVH show positive staining for CD31 and smooth muscle actin and typically, negative staining for the human herpes virus 8 antigen. We report a rare case of multiple MVH clinically mimicking the early patch stage of Kaposi sarcoma in a 63-year-old woman who presented with a 3-year history of slowly growing, compressible, soft, bluish-purple macules and plaques on the trunk and right arm.
