  • Nevus lipomatosus superficialis (NLS) is a hamartoma of adipose tissue, rarely reported in the past 100 years. We treated one case, and we conducted a systematic review of the literature. A 41-year-old man presented with a cutaneous multinodular lesion in the posterior region near the right auricle. The lesion was excised and examined histopathologically. To review the literature, we searched PubMed with the keyword "NLS." The search was limited to articles written in English and whose full text was available. We analyzed the following data: year of report, nation of corresponding author, sex of patient, age at onset, duration of disease, location of lesion, type of lesion, associated symptoms, pathological findings, and treatment. Of 158 relevant articles in PubMed, 112 fulfilled our inclusion criteria; these referred to a total of 149 cases (cases with insufficient clinical information were excluded). In rare cases, the diagnosis of NLS was confirmed when the lesion coexisted with sebaceous trichofolliculoma and Demodex infestation. Clinical awareness for NLS has increased recently. NLS is an indolent and asymptomatic benign neoplasm that may exhibit malignant behavior in terms of huge lesion size and specific anatomical location. Early detection and curative treatment should be promoted.

  • Human alveolar echinococcosis (AE), a hepatic disorder that resembles liver cancer, is a highly aggressive and lethal zoonotic infection caused by the larval stage of the fox tapeworm, Echinococcus multilocularis. E. multilocularis is widely distributed in the northern hemisphere; the disease-endemic area stretches from north America through Europe to central and east Asia, including northern parts of Japan, but it has not been reported in Korea. Herein, we represent a first case of AE in Korea. A 41-year-old woman was found to have a large liver mass on routine medical examination. The excised mass showed multinodular, necrotic, and spongiform appearance with small irregular pseudocystic spaces. Microscopically, the mass was composed of chronic granulomatous inflammation with extensive coagulation necrosis and parasite-like structure, which was revealed as parasitic vesicles and laminated layer delineated by periodic acid-Schiff (PAS) stain. Clinical and histologic features were consistent with AE. After 8 years, a new liver mass and multiple metastatic pulmonary nodules were found and the recurred mass showed similar histologic features to the initial mass. She had never visited endemic areas of AE, and thus the exact infection route is unclear.

  • 우측 후지가 점진적인 파행을 보이는 11년령의 수컷 시츄견이 내원하였다. 신체검사 결과 부정형의 종괴가 촉진 되었다. 방사선 촬영에서는 균질한 연부 조직성 밀도를 보였으며, 초음파 검사에서는 혼합성 에코를 보이는 경계가 명료한 특징을 갖고 있었다. MRI 검사에서는 주변 근육과 비교한 결과 유사 또는 강한 비균질성 신호강도를 보였다. 종괴는 주로 대퇴부 주변에 형성되어 있었으며, 일부는 골반뼈 폐쇄구멍을 통해 골반강내에서 직장의 변위를 일으키고 있음이 확인할 수 있었다. 병리조직 검사 결과 중간엽 세포와 상피세포로 구성된 활막육종으로 진단되었다. 종괴는 외과적으로 적출하였으나, 지속적인 근위축으로 있었으며 인해 파행은 개선되지 않았다. 적출 후 6개월에 종괴가 형성됨이 확인되었으며 점진적으로 그 크기 비대해져 10개월이 되는 시점에서 견주의 요청으로 안락사 하였다. MRI는 활막육종 형성됨이 확인되었으며 이에 대한 특징적인 소견은 내포하고 있지 않지만 종괴의 수술적 적출과 종괴의 범위를 확인하는데 있어 유용한 정보를 제공함을 알 수 있었다.

  • Purpose: Ganglion cysts of peripheral nerve are uncommon. Ganglion cysts located within the nerve and extraneural ganglia that cause symptomatic nerve compression have been reported. We report an unusual case of epineural ganglion cyst confined to the epineurium of the sural nerve at the foot. Methods: A 45-year-old woman was referred because of a mass on the foot. She had six months' history of pain and numbness in the right small toe. During the examination of the lesion, multinodular cystic mass was identified arising from the epineurium of the sural nerve. The nerve fascicles were compressed by the cyst, but the cyst wall clearly did not invade the fascicle. With the aid of surgical microscope, the epineural cyst was completely excised along with epineural tissue to which it was attached, and the sural nerve was decompressed. There was no relationship between the cyst and either the joint capsule or tendon sheath. Since the cyst was on the periphery of the nerve it was possible to remove the cyst intact without damaging the underlying fascicles. Results: The postoperative course was uneventful. Pathologic examination showed a ganglion cyst with a degenerated collagen fibers and contained a yellowish, jelly-like mucinous substance. No neural elements were identified within the cystic wall. Her sensory impairment improved progressively. At the 15 months follow-up, she was asymptomatic with no neurological deficits. Conclusion: Rarely, ganglion cysts can involve peripheral nerves, leading to varing degrees of neurological deficits. Intraneural intrafascicular ganglion may be difficult to separate from the neural elements without nerve injury. Epineural ganglion, subcategorized as intraneural extrafascicular ganglion, can be removed without damage to the underlying nerve.

  • Transarterial chemoembolization (TACE) is a widely accepted nonsurgical modality used for the treatment of multinodular hepatocellular carcinoma (HCC). The careful selection of the candidate is important due to the risk of developing various side effects. Fever, nausea, abdominal pain, and liver enzyme elevation are commonly known side effects of TACE. Hepatic failure, ischemic cholecystitis, and cerebral embolism are also reported, although their incidence might be low. Pulmonary complication after TACE is rare, and the reported cases of lipiodol pneumonitis are even rarer. A 53-year-old man was treated with TACE for ruptured HCC associated with hepatitis B virus infection. On day 19 after the procedure, the patient complained of dyspnea and dry cough. Chest computed tomography showed diffuse ground glass opacities in the whole-lung fields, suggesting lipiodol-induced pneumonitis. After 2 weeks of conservative management, the clinical symptoms and radiologic abnormalities improved. Reported herein is the aforementioned case of lipiodol-induced pnemonitis after TACE, with literature review.

  • 절제 불가능한 원발성 간암은 여러 가지 다양한 치료법의 시도에도 불구하고 그 예후는 극히 불량하다. 이에 본 저자들은 온열요법에 대한 축적된 경험을 바탕으로 1988년 4월부터 7월까지 본과에 내원한 30명 의 절제 불가능한 원발성 간암 환자들에 대하여 온열 및 방사선 병용요법을 시행하였다. 방사선치료는 일일 조사량 180 cGy씩 3. 5주에 3060 cGy를 조사하였고 온열요법은 8 MHz 유전형온열치료기 (Thermotron RF-8, Cancermia)를 사용하여 주 2회씩 총 5회 시행하되 순서는 방사선 치료를 먼저 한 후 30분 이내에 온열요법이 30~60분간 시행되었다. 그 결과 부분반응이 12예에서 관찰되었고(40%), 증상의 호전이 28예 중 22예에서 관찰되었다(78.6%), 종양의 반응을 예측할 수 있는 인자로서는 형태학적 유형이 가장 유의하게 나타났다(single massive: 10/14, 71.4%, diffuse infiltrative: 2/10, 20% : multinodular : 0/6, 0%, p<0.005). 치료로 인한 심각한 부작용은 관찰되지 않았다. 1년 생존율은 34%였고 정중앙 생존기 간은 6.5개월이었다. 부분반응을 보인 환자군의 생존율 및 정중앙 생존 기간은 각각 50%, 11개월로서 반응을 보이지 않은 환자군의 22%, 5개월과 비교해 볼 때 정중앙 생존기간의 차이가 통계적으로 유의하였다.(p<0.05). 결론적으로 온열 및 방사선 병용요법은 절제 불가능한 원발성 간암의 증상호전 및 국소적 치료에 효과가 있는 것으로 생각되며 생존율 및 부작용 등에 관해서는 앞으로 연구가 더 진행되어야 할 것으로 생각된다.

  • Background and Objectives: When the pleomorphic adenoma(PA) recures, the tumor tends to become a multinodular mass that infiltrates into the normal tissue which is not a common condition for a benign tumor. This manifestation is probably due to the difference in cell biology of the recurrent tumor compared to that of the primary PA. The aim of this study is to assay the immunhistochemical characteristics of the recurrent PA compared to the primary PA and to evaluate whether this property can be used for developing a method that can select the patients who have higher risk to recur. Materials and Methods: Thirteen patients were enrolled in the primary PA group and 15 patients who had a recurrent PA were enrolled in the recurrent PA group. To evaluate the cell biology of the tumor, immunohistochemical stainings of Ki-67, bcl-2 and p53 were performed. Results: There was no difference in the expression of Ki-67 (p=0.117, p=.208) and p53 (p=.430, p=.328). The extent stained by bcl-2 was significantly larger in the recurrent PA group (p=.033, p=.014). The expression of bcl-2 did not increase while time passed. Conclusion: The high expression of bcl-2 seems to be a property of the recurrent PA group which can be found even during first operation before recurrence. By this immunhistochemical characteristic, we would be able to sort out the patients who have higher risk to recur.
