The dysplasitc melanocytic nevus(DMN) of the skin is an atypical-appearing melanocytic tumor characterized by intraepidermal atypical melanocytic preliferation. Clinically, DMN has a diameter greater than 5mm, ill-defined irregular borders, irregularly distributed pigmentation surrounded by erythems,. Histopat- hologically, there are numerous discrete nests of atypical melanocytes situated at the dermoepidermal junction of elongated rete ridges. In the dermis, concentric lamellar fibroplasia, lymphocytic infiltrates and neovascularization are noted. We report herein a case of DMN developed on the trunk of 31-year-old Korean male.

Diabetic and nondiabetic vascular diseases cause significant foot problems and it frequently progress to osteomyelitis and amputation. Advances in vascular surgical techniques, including distal arterial bypass via synthetic grafts or autogenous vein grafting have opened the way for higher rate of limb salvage. We have experienced patients with ischemic vascular foot disease and combined skin ulceration and varing degree of soft tissue defect. In three patient with major vessel obstruction, we could preserve limb and avoid major amputation using greater saphenous vein graft with or without microvascular free tissue transfer.

A Clinical observation was made on five patients with ruptured right aortic sinus of valsalva who admitted Soonchunhyang College Hospital during the period of may, 1983-Jan., 1985. 1) Age distribution was from 18 to 46 years and four patients were male and the rest one was female. 2) Chief complaints were dyspnea, chest pain and palpitation. Continuous murmur was heard at third and fourth intercostal space along left sternal border with palpable thrill in all cases. 3) The ECG showed left ventricular hypertrophy in 4 cases and the M mode echocardiogram revealed the increased internal dimesion and the augmented motion of the left ventricle in all cases. The 2 dimensional echocardiogram revealed the aneurysmal sac in the right ventricle in 4 cases. 4) The aortogram by DSA method showed regurgitant flow from aorta to right ventricle in 4 cases. The cardiac catheterization showed a significant oxygen step up in the right ventricle in all cases. 5) Operation was done successfully in all cases, of which ventricular septal defect were in 3 cases and aortic regurgitation was in one case.

The authors conducted a clinical observation of 55 cases of solitary pulmonary nodules at Yeungnam University Hospital from June 1986 to October 1990, and the following results were obtained: 1. The age distribution was ranged from 18 to 77 years, and the male-to female ratio was 1.8:1. 2. Among 55 cases of nodules, 28 cases were benign and 27 cases were malignant nodules, and of malignant nodules, the primary lung cancer was 23 cases and of benign nodules, 18 cases were tuberculoma. 3. 23 cases (41.8%) was asymptomatic and the other 32 cases were symptomatic; chest pain 12 cases, hemoptysis; 8 cases, cough; 8 cases and dyspnea; 4 cases. 4. The non-smoker-to-smoker ratio was 1:1.04, but among 23 smoker over 20 pack years, 14 cases were malignant nodules. 5. According to nodular size, there is no striking differences between benign and malignant nodules except 3-4 cm sized nodules. 6. The lobar distribution of nodules, 35 cases were in the right lung (upper lobe; 14 cases, middle lobe; 11 cases, and lower lobe; 10 cases) and 23 cases were in the left lung (upper lobe; 9 cases, lower lobe; 11 cases), and the malignant nodules were most commonly observed in the right upper lung.

OBJECTIVE: This study was undertaken to evaluate the feasibility of minimally invasive posterior surgical approach for cervical disc diseases. METHODS: The authors performed cervical key hole foraminotomies using the microendoscopic discectomy (MED) system in four cadaveric cervical spine specimens. Three non-contiguous cervical nerve roots were selected between C3 and C8 in each specimen and were decompressed using MED system on one side. Contralateral sides were decompressed using the open foraminotomy procedure. The amount of bony decompression achieved with the MED system was compared to that achieved with the open foraminotomy procedure in each cadaveric specimen. RESULTS: Postop CT-myelogram and postoperative open dissection showed adequate bony decompression was achieved with either the MED or open procedure in all specimens. The laminotomy size(vertical and transverse diameter), the length of decompressed nerve root, and the proportion of removed facet joint were measured on every operated level. The average vertical diameter of laminotomy area and the percentage of facet removed were significantly greater in the MED procedure than the open procedure(p<0.05). The transverse diameter of the laminotomy area and the average decompressed root length were not significantly different between MED and open surgery. CONCLUSION: We conclude endoscopic cervical foraminotomy using the MED system is a feasible procedure and may be applicable to the treatment of foraminal stenosis and laterally located cervical disc herniation in clinical settings.
