A lipomatous lesion of the cord is an accidentally encountered structure during the operative repair of inguinal hernia. This lesion has been reported as a lipoma of the cord in adults. However, there is only a limited number of reports in the pediatric age group. To evaluate the prevalence of this lesion in children and in order to review the surgical signiticancies, 600 hernia operations in 411 children during a period of 4 years from January, 2000 to December, 2003 in the Division of Pediatric Surgery, Department of Surgery, the Catholic University of Korea, were included in this study. There was a total of 31 (5.2 %) lipomatous lesions in 25 (6.1 %) cases; 3 cases in infants, 17 between 1 to 4 years, and 5 above 5 years of age. Male was more prevalent (male to female ratio 14:11). The laterality of clinical hernia with the lesions was 10 in the right, 13 in the left and 2 in both sides. The patients with ipsilateral lesions to the hernia were 14, contralateral in 5 and bilateral in 6 cases. Excluding 1 case of bilateral lesions in bilateral hernia, 10 lesions were contralateral to the clinical hernias. In 1 case, lipomatous lesion was the sole finding with nonsignificant patent processus vaginalis. Every lesion was suture ligated and resected with gentle traction of the dissected hernia sac. It has not been clearly defined whether the lesion is a stopper or a provocator of the hernia development. However, removal is highly recommended to make a differential diagnosis from the recurrent inguinal hernia in future. The term "lipomatous lesion" seems to be pathologically accurate and must be differentiate from the true lipomas.

A 26-year-old man with renal cell carcinoma underwent $^{99m}Tc$-HDP bone scintigraphy for detecting bony metastasis after left total nephrectomy for renal cell carcinoma. $^{99m}Tc$-HDP bone scintigraphy showed small hot lesion in the first lumbar spine. About 12 months later, he underwent spinal MRI for lower back pain. A large mass was seen around spinous process of the first lumbar spine (L1) on spinal MRI and confirmed as metastatic renal cell carcinoma by bone biopsy. $^{99m}Tc$-HDP bone scintigraphy and $^{18}F$-FDG PET/CT were underwent for further evaluation. $^{99m}Tc$-HDP bone scintigraphy showed cold lesion in the first lumbar spine which was initially hot and newly developed hot lesion in the twelfth thoracic spine, and which were shown as hypermetabolic lesions in $^{18}F$-FDG PET/CT. We report a case of bony metastasis from renal cell carcinoma which is changed from hot lesion to cold lesion in $^{99m}Tc$-HDP bone scintigraphy and compare with $^{18}F$-FDG PET/CT.

Among 2,373 slaughtered pigs examined for one year(March 1995 to February 1996), 1,899 pigs had visible pulmonary lesions. Prevalence rate of pulmonary lesion was examined by pathological techniques according to rearing and health managements of pig farms. The results were as follows : 1. Prevalence rate of pulmonary lesion in all-in/all-out flow farms(71.9%) was lower than that in continous flow farms(85.2%). 2. Prevalence rate of pulmonary lesion in non-infected farms with Aujeszky's disease virus and/or porcine reproductive and respiratory syndrome virus(74.4%) was lower than that in infected farms(85.5%). 3. During winter, prevalence rate of pulmonary lesion in farms with cold-control facilities(83.2%) was lower than that in farms with poor cold-control facilities.

Osteochondral lesion usually occurs in the elbow, knee and ankle joints. Many articles about osteochondral lesion of the talus in the ankle joint have been reported. We experienced a rare case of partially detached osteochondral lesion of the tibial plafond treated with excision and multiple drilling.

Circumscribed solitary pulmonary nodule is often founded on the plain chest P-A. Even if many study results of coin lesion have been reported by some scholars, it is still very difficult to judge whether the coin lesion is to be benign or malignant. In order to avoid unnecessary surgical treatment, it must be made an examination and analysis very carefully in advance. In the chest P-A, we can grasp the aspects of the site and size of lesion, marginal state of lesion, calcification, cavity, and the growth rate in comparison to follow-up chest P-A. On the basis of above-mentioned analysis, we have to judge whether it is benign or malignant, and decide the next examinations. And then the doctor make diagnosis definitely by the clinical history, plain chest P-A, tomography, bronchography, CT, variable laboratory findings.

A series of greenhouse test was conducted to evaluate infection of Calonectria ilicicola on soybean plants of different ages at time of inoculation. Lesion length and number of perithecia were determined on cultivars Braxton, Deltapine 726, and Riverside 699 that were 10∼40 days old and 4-10 days old at time of inoculation. Quadratic and linear relationships were described between plant age at inoculation and lesion length or perithecia production in greenhouse studies. Soybean seedlings exhibited low susceptibility to C. ilicicola regardless of cultivar susceptibility. On 8- or 1-0-days-old Braxton, lesion lenght and perithecia numbers were reduced. Lesion lengths were longest on plants 30 days old whereas perithecia production was greatest on plants 20∼30 days old at time of inoculation. Differences in lesion length and perithecia production that were observed on young plants (4∼10 days old) were similar to relative levels of susceptibility in soybean cultivars in greenhouse and field tests, suggesting that reaction to C. ilicicola in soybean cultivars may be determined early in plant development.

Microfracture as a reparative strategy is the treatment of choice for an osteochondral lesion of talus. Although the results of microfracture are generally excellent, at least 30% of patients who received microfracture have acute or chronic ankle pain with several or unknown causes. The most important factor for unsatisfactory outcome after microfracture is the size of the lesion. For failed osteochondral lesion of talus, the second options are autologous osteochondral graft, autologous chondrocyte implantation, or re-microfracture. In this article, we present the autologous chondrocyte implantation as a second procedure for failed microfracture and compare its clinical outcome with other methods based on a literature review.

Parosteal osteosarcoma is characterized as a densely ossifying lesion, usually occurring on the surface near the metaphyses of a long bone. The histological pattern is a well- differentiated mature bone trabeculae with a hypocellular spindle-cell stroma. The cytological details are those of a low-grade malignant lesion. The natural history of this lesion is indolent local growth, late invasion of the underlying bone, and infrequently, distant metastasis. However, there is a significant risk of eventual dedifferentiation into a high-grade lesion. We report here-a case of parosteal osteosarcoma dedifferentiated into a high-grade lesion, which occurred in the left distal femur of a 40-years-old woman, and discuss the experience in detail.

Oral precancerous lesion is a morphologically altered tissue in which oral cancer is more likely to occur than is apparently normal counterpart. As dentists always do oral examination and dental treatment, with fundamental knowledge and attention of this lesion, it is relatively easy to find one. If followed by proper treatment and management, it is possible to minimize its oral cancer progression, or at least delay it. Even if it were to progress to oral cancer, very early detection is possible. However, no specific biomarkers are present at the moment that could reveal oral precnacerous lesion that is high risk of oral cancer progression. Since early detection of oral cancer followed by treatment could show good prognosis with just a simple ablative surgery. Dentists should also instruct people to avoid risk factor related oral cancer progression and take natural compound having anticancer effect. Hereby, As a primary care givers, dentists play an important role in prevention of oral cancer.

A Morel-Lavallée lesion is a closed degloving injury caused by traumatic separation of the skin and subcutaneous tissue from the underlying fascia. However, since physicians tend to focus on treating the bone fracture, hemodynamic instability accompanying a Morel-Lavallée lesion can sometimes be overlooked. We report the case of a hemodynamically unstable 73-year-old man who had a Morel-Lavallée lesion of the thigh, but no femur fracture. Angiography showed active bleeding from the muscular branch of the right deep femoral artery, which was then successfully embolized.
