We describe the clinical and pathologic observation of a 50-year-old man with superficial disseminated porokeratosis who developed a squamous cell carcinoma on the dorsum of his right thumb and Bowens disease on his right upper arm. The tumors were surrounded by lesions of superficial disseminated porokeratosis and were thought to develop from the dysplastic epidermal cells located under the comoid lamellae.

Ki-1 lymphoma is a rare, large cell anaplastic non Hodgkin's lymphoma. It expresses the CD30 antigen and is recognized by the antibodies Ki-1. This Ki-1 positive anaplastic lymphoma was first described in 1985 as a new histological subtype and was added to the updated Kiel classification in 1988. Morphological and immunological features of this lymphoma have been well described, but clinical studies have been limited and follow up has been short. The authors report a case of Ki-1 lymphoma of the skin without systemic involvement in a young adult based on clinical, pathological and immunological features.

Radiological investigation in patients with clonorchiasis is very important as this is the only method of evaluating the severity of clonorchiasis. In order to correlate the radiologic and pathologic findings of clonorchiasis, fourteen rabbits infested with Clonorchis sinensis and five control rabbits were examined radiologically by ultrasonography, computed tomography and cholangiography and the results were correlated with pathologic findings. Dilatation of the intrahepatic small bile ducts of the liver was due to obstruction by flukes: oval or elliptical small filling defects or irregular margin of the bile ducts on cholangiogram or intraluminal echoes on sonogram represented flukes per se; periductal thickening on sonogram and periductal enhancement of bile ducts on CT were due to inflammatory cell infiltration, adenomatous hyperplasia and periductal fibrosis: band like enhancement at the periphery of the liver on CT represented proliferated bile ducts, destruction of liver cells and resultant fibrosis. The study confirmed the pathological bases for the radiological findings of clonorchiasis in liver and bile ducts and will, perhaps, serve as a basis for the future radiologic-pathological correlation of clonorchiasis and in further clinical and experimental researches in the biliary tract diseases.

From retrospective review of 111 tibial fractures treated by interlocking intramedullary nailing, 38 operative errors in 28 cases(25%) were included in this study. The errors were classified into two categories. The first category included eighteen errors that related to fracture reduction; nine angular malalignments, four failures in closed nailing to open the fracture site, two peroneal nerve palsies, two shortenings of tibial length(more than 1cm), and one rotational malalignment. The second category comprised twenty errors that related to the nailing itself; eight protrusions of proximal nail tip, five overdistractions of fracture gap (more than 3mm), four additional fragmentations, two mistakes in interlocking screw insertion, and one ankle joint injury by the distal nail tip. Functional results of those 28 cases at the last follow-up(average, 17.5 months; range, 9 to 29 months) were excellent or good in only 60.8 per cent, while the control group treated by adequate operative technique showed excellent or good results in 92.8 per cent.

As a partial effort of the survey in the National Plan for the Eye Health, the analysis of the visual impairment mainly refractive errors among 4,004 School Children in Seoul(1986) with the ancilliary questionnaire on various conditions was attempted. The number of the student with subnormal vision(0.7 or less) was 1,552(38.8 %), and this rate was increased with the higher school grade. Of the 2,551 eyes with subnormal vision(0.7 or less), the confirmed refractive errors consisted of myopia 2,170(78.7%), hyperopia 237(8.6%), and mixed astigmatism 144(5.2%) eyes. The number of glasses wearer among the students of vision 0.5 or below(1,129) was 770(63.2%), of which the under-corrected cases 380(49.3%) weregreater in number with the over corrected cases. The causes of not-wearing glasses in the students who belonged to the vision 0.5 or below indicated in prominence of numbers of 1) no complaints without glasses in 172(42.0%), 2) unwareness of the visual impairment in 77(20.0%), and 3) annoyance to wearing glasses in 51(13.4%), rather than economical reasons in 12(3.1%). The amblyopic components were estimated among 129 cases(3.2%) in combination of refractive errors. Further program to supply the glasses with appropriated prescription and the details on the practical aspects of related elements would be discussed.
