The author observed one case of typical Linear bassal cell nevus who was 3 year old girl. Since birth, skin lesions reveal a linear band like nodules along the left lateral margin of nose, which are consists of pinhead sized, normal skin colored, pearly and translucent papules. Histopathologically, the preparations showed muItifocal irregular masses of basal type epithelial cells in continuity at pilosebaceous follicles and the cells were oval or spindle shaped and a peripheral palisade arrangement. But comedones and nevus cells were not identified. Diagnosis confirmed by clinical appearance, histopathologically and other clinical study. There were marked improvement by the locaI application of 2% 5-Fluorouracil solution.

BACKGROUND: Vitiligo is a relatively common acquired depigmentating disorder that affects at least 1 % of the population. The mode of transmission has not been clearly,stablished, but either polygenic or autosomal dominant with incomplete penetrance and variable expresion has been proposed. OBJECTIVE: Our purpose was to evaluate the causative factor, variable clinical features and current teratment of generalized vitiligo patients. METHOD: This clinical in vestigation was made with 225 outpatiens of generalized type vitiligo who had visited the Department of Dermatology, Keirnyung Universitv Hospital from January 1987 till December 1991. Results & CONCLUSION: 1. There were 125 female, (55.5%) and 100 males(44.4%). 2. The mean age of onset was 21.4 years(male . 24.3, female: 19.1). 3. The mean age at the first visit was 27.5 years (male : 28.8, female : 26.5). 4. The mean duration of the disease was 10.7 years(male : 9.9, female : 10.9). 5. The mean interval between onset and visiting was 6.1 years (male : 4.5, female : 7.4). 6. The most common sites of involvernent at the first visit was tie face 11.7% (male : 11.4%, female : 11.8%). 7. The most common precipitating factor was trauma(8.8%). 8. The most common previous treatment was sunlight irradiaion after application of topical oxoralene(33.2%). 9. The most common degree of depigmented lesion was 5-10%(64.4%). 10. The most common occupations of the patients were students mals, and housewife females.

Hemophagocytic lymphohistiocytosis (HLH) is a condition caused by excessive activation and expansion of T lymphocytes and macrophagic histiocytes that exhibit hemophagocytic activity. It is a life-threatening condition, and the reported mortality rates reach 20% to 30%. It is usually associated with infection, malignancy, or autoimmune disease, but rarely with rheumatoid arthritis (RA). We recently experienced a case of HLH with rapid progression resulting in mortality in a 38-year-old female patient with long-standing RA. She visited the clinic for evaluation of a common cold-like illness. She had hypotension, liver enzyme elevation, and pancytopenia. After admission, her hypotension continued and disseminated intravascular coagulation and metabolic acidosis developed and progressed with the appearance of azotemia. Despite supportive management, she died on the fifth hospital day. HLH should be considered as a differential diagnosis when patients with RA show acute illness with fever, cytopenia, hepatic failure, and coagulopathy.

Keratocystic odontogenic tumors (KCOT) - previously termed odontogenic keratocysts (OKC) - are characterized by aggressive behavior and a high rate of recurrence. Histopathologically, the basal layer of KCOT shows a higher cell proliferation rate and increased expression of anti-apoptosis genes. Clinically, KCOT is frequently involved in the mandibular posterior region but is not common in the posterior maxilla. However, it should be noted that due to its expansive characteristics, KCOT involved near the maxillary sinus could easily expand to an enormous size and occupy the entire maxilla. To achieve total excision of these expanded cystic tumors in the maxilla, a more aggressive approach would be needed. In this report, we describe two cases of expansile KCOT involving the entire unilateral maxilla and maxillary sinus; they were completely excised using the Weber-Ferguson approach, showing no evidence of recurrence during the follow-up period of more than two years. In immunohistochemical analyses of the tumor specimens, p53 and p63 showed strong expression, and B-cell lymphoma 2 (BCL2) and MKI67 (Ki-67) showed moderate or weak expression, however, detection of BCL2-associated X protein (BAX) was almost negative. These data indicate that expansile KCOT possesses increased anti-apoptotic activity and cell proliferation rate but decreased apoptosis. These properties of KCOT may contribute to tumor enlargement, aggressive behavior, and high recurrence rate.

PURPOSE: To report a case of uveitis in both eyes caused by Sweet's syndrome. CASE SUMMARY: A 66-year-old male presented with decreased visual acuity in his left eye. Three years prior he was diagnosed with Sweet's syndrome, with symptoms such as chill, fever and, maculopapular rash on the chest. At initial physical examination, he had 3 or 4+ inflammatory cells and flare in the anterior chambers of both eyes, as well as hypopyon in his left eye. Under the suspicion of uveitis caused by Sweet's syndrome, he was rescribed an IV steroid injection and topical steroid agent. Three days later, his visual acuity improved to 0.3 in the right eye and 0.2 in the left eye. Hypopyon in the left eye disappeared and inflammatory cells decreased to 1~2+. He showed signs of recurrence in both eyes after 5 months and was treated with posterior subtenon triamcinolone injection in each eye. The patient showed no signs of recurrence for 10 months after injection. CONCLUSIONS: We report a case of uveitis caused by Sweet's syndrome treated with a steroid agent resulting in good prognosis. To the best of our knowledge, this is first case of uveitis caused by Sweet's syndrome reported in Korea.

BACKGROUND: The prevalence of type 2 diabetes in elderly people has increased dramatically in the last few decades. This study was designed to clarify the clinical characteristics of type 2 diabetes in patients aged ≥80 years according to age of onset. METHODS: We reviewed the medical records of 289 patients aged ≥80 years with type 2 diabetes at the outpatient diabetes clinics of Kangwon National University Hospital from September 2010 to June 2014. We divided the patients into middle-age-onset diabetes (onset before 65 years of age) and elderly-onset diabetes (onset at 65+ years of age). RESULTS: There were 141 male and 148 female patients. The patients had a mean age of 83.2±2.9 years and the mean duration of diabetes was 14.3±10.4 years. One hundred and ninety-nine patients had elderly-onset diabetes. The patients with elderly-onset diabetes had a significantly lower frequency of diabetic retinopathy and nephropathy, lower serum creatinine levels, lower glycated hemoglobin (HbA1c) levels, and similar coronary revascularization and cerebral infarction rates compared to those with middle-age-onset diabetes. There was no frequency difference in coronary revascularization and cerebral infarction and HbA1c levels between three subgroups (<5, 5 to 15, and ≥15 years) of diabetes duration in elderly onset diabetes. However, both in the elderly onset diabetes and middle-age-onset diabetes, the cumulative incidence of retinopathy was increasing rapidly according to the duration of diabetes. CONCLUSION: We report that individuals with elderly-onset diabetes have a lower frequency of diabetic retinopathy and nephropathy and similar cardiovascular complications compared to those with middle-age-onset diabetes.

During surgical procedures, unexpected material, including surgical instruments and tissue segments, may get lost in the surgical field. Most of these should be immediately removed to prevent further complications, such as vital organ irritation, infection, and inflammatory pseudo-tumor formation. However, it is not always easy to define the exact location of the foreign body, especially if the item is very small and/or it is embedded in the soft tissue of the head and neck region. Intraoperative real-time radiological imaging with C-arm fluoroscopy can be useful to trace the three-dimensional location of small and embedded foreign bodies in the oral and maxillofacial area. We describe an unusual case of an embedded micro-screw in the intrinsic tongue muscle that had been dropped into the sublingual space during a lower alveolar bone graft procedure. The lost foreign body was accurately identified with C-arm fluoroscopy and safely removed without any further complications.

Chronic active Epstein-Barr virus infection(CAEBV) is a nonfamilial syndrome that shows a specific immunodeficiency for the Epstein-Barr virus(EBV). CAEBV is characterized by fever, lymphadenopathy, splenomegaly, hepatitis, interstitial pneumonitis, interstitial nephritis, and uveitis. Cardiovascular complications are rare in EBV infection. Patients with CAEBV show characteristically high titers of anti-viral capsid antigen(VCA) IgG antibody and anti-early antigen(EA) antibody, as well as relatively low titer of anti-EB nuclear antigen(EBNA) antibody. We experienced a case of CAEBV with giant coronary aneurysms, who was a 6-year-old boy. He had 5 episodes of high fever and cervical lymphadenopathy and hepatosplenomegaly. The 6 mm sized bilateral coronary aneurysms were detected by echocardiography at second admission. IgG antibodies to EBV was positive, whereas negative for IgM antibody. Antibodies to EA and EBNA were also positive. The EBV was detected in lymph node tissue by in situ hybridization, and in the peripheral blood and bone marrow by the PCR. Treatment has been done with ganciclovir and interferon (IFN)-alpa for 5 weeks. The EBV-PCR of peripheral blood was converted to negative from 12th day of treatment. At present he has followed well for two years without fever and enlargements of lymphnode, except large coronary aneurysm.

A 70-year-old woman was admitted to our department with epigastric discomfort and nausea over the duration of 1 month. An esophagogastroduodenoscopy showed the presence of a 1.0x1.0 cm-sized flat lesion with central ulceration at the greater curvature side of the antrum. A biopsy demonstrated the presence of an adenocarcinoma of well differentiated, intestinal type in the stomach. Endoscopic submucosal dissection was done and the diagnosis of a composite neuroendocrine carcinoma with an adenocarcinoma of the stomach was confirmed. We report a case of a gastric composite tumor with an adenocarcinoma and neuroendocrine carcinoma confirmed by endoscopic submucosal dissection with a review of the literature.
