From 2,373 slaughtered pigs examined, 1,899 of them had visible evidence of pulmonary lesion. The lungs with pulmonary lesion were examined by grossly, histopathological technique to investigate the prevalence according to season, severity of pulmonary lesion, types of the pneumonia and relationship between rearing management and prevalence of pulmonary lesion. The results were as follows : 1. Prevalence of pneumonia according to season was 72.3% to 85.9% and the highest prevalence was in winter. 2. In the severity of pulmonary lesion, rates mild, moderate and severe lesions were 38.3%, 47.0% and 14.7%, respectively. Prevalence of mild lesion was the highest in autumn. Prevalence of moderate and severe lesions was the highest in winter. 3. In the type of pneumonia, rates of interstitial pneumonia and bronchopneumonia fibrinous pneumonia were 23.6%, 13.0%, and 3.4%, respectively. Prevalence of interstitial pneumonia was high in spring and autumn while that of broncho-pneumonia and fibrinous pneumonia was high in winter and summer, respectively. 4. In relationship of pulmonary lesions according to severity of pulmonary lesion and types of pneumonia, similarity was observed in prevalence of mild lesion and bronchopneumonia.

We report a case of large radicular cyst progression related to endodontic origin to emphasize proper intervention and follow-up for endodontic pathosis. A 25 yr old man presented with an endodontically treated molar with radiolucency. He denied any intervention because of a lack of discomfort. Five years later, the patient returned. The previous periapical lesion had drastically enlarged and involved two adjacent teeth. Cystic lesion removal and apicoectomy were performed on the tooth. Histopathological analysis revealed that the lesion was an inflammatory radicular cyst. The patient did not report any discomfort except for moderate swelling 3 days after the surgical procedure. Although the patient had been asymptomatic, close follow-ups are critical to determine if any periapical lesions persist after root canal treatment.

Malignant fibrous histiocytoma is one of the most common soft tissue sarcomas in late adult life. but its incidence in oral and maxillofacial region is extremely rare. We report a case of malignant fibrous histiocytoma which occurred in the infratemporal fossa. Conventional radiograph of this case showed an ill-defined radiolucent lesion in the alveolar bone of the right maxillary first molar area. the lateral wall of the maxillary sinus. and the ascending ramus of mandible. MRI demonstrated a well defined mass of intermediate signal intensitiy in Tl weighted images but T2 weighted images showed two distinctive regions of different characteristics. Upper portion of the lesion was of hyperintense signal but (at) lower portion, the signal intensity decreased clearly, which might mean that this lesion(mass) is composed of two different subtypes though it couldn't be confirmed by histopathological examination. Biopsy was taken the lesion as only in the soft tissue of the maxillary posterior alveolar region and confirmed the storiform-pleomorphic type of malignant fibrous histiocytoma. Histopathological subtype was well consistent with the relatively aggressive imaging findings of that region. We expect more detailed analysis of the nature of malignant fibrous histiocytoma with improvement of the imaging modality and the identification of the relationship between diagnostic imaging and histopathologic findings.

The aims of this study were to assess the lung lesions and to compare gross observations with histopathological findings in the lungs of slaughter pigs. During August of 2010 through July of 2011, the 1,200 lung samples were randomly collected from slaughtered pigs in Korea. We examined prevalence of lung lesions and classified the lung lesion according to the severity of lung lesions. For the comparison of gross lesions with histopathological findings, BALT hyperplasia was also examined. Among the tested samples, 1,100 (91.7%) had pneumonic lung lesions. In the seasonal prevalence of pneumonic lung lesions, spring was the highest followed by winter, summer and autumn, respectively. The mean pneumonic score ($mean{\pm}SD$) was $21.37{\pm}17.87$ and the highest gross lesion according to stages was 11~20% (27.2%, 326/1,200). The prevalence of pleuritis was 7.0% and the highest prevalence was determined in summer. In severity, the lungs collected in this study were frequently in chronic stage (36.4%, 437/1,200), and it was shown that BALT hyperplasia was more extensive in chronic lesion. In this study, the prevalence of pneumonic lung lesions showed a high side and appeared particularly high in the spring. Severity of lung lesion was the most prevalent chronic lesions which were consistent with histopathologic findings.

The outbreak of haemorrhagic speticemia and dermal lesions in cultured Rock sea breem in Jeju Island are frequently associated with keratitis. Prolonged infection leads to the symptoms accompanied by necrosis of fin and skin and the fishes died. Present study aims to study the histopathological changes of diseased fish muscle tissue. The tissue at the initial stage of infection showed normal muscular texture, however in the late stages of infection, muscular lesion had been expanded and hence, necrosis had progressed deeply into muscle tissue. Mild tissue in caudal fin was found with more necrosis, and gill tissues were also collapsed. In Kidney, renal tubules were teared along with tissue destruction (Espada, J et al, 1993). Hence in the present study, we examined the histopathological variation of the infection fishes, and this basic data would be used for future research of in haemorrhagic specticemia and dermal diseases.

Angiolymphoid hyperplasia with eosinophilia(ALHE) is a benign subcutaneous lesion that primarily affects head and neck region. It is characterized by single or multiple nodules in the subcutaneous tissue associated with eosinophilia in the peripheral blood. Kimura's disease, originally reported by Kimura et al., is similar lesion with ALHE in the clinical and histopathological aspects. There has been considerable controversy about the relation between Kimura's disease and ALHE. In Korea, 26 cases of Kimura's disease and ALHE have been reported since 1975. We present a case of recurred ALHE occurring on the left cheek in a 58-year-old woman. Including this case, we summarized all cases that were reported as Kimura's disease or ALHE in Korea through literature review. We also give an outline of clinical and histopathological characteristics of cases reported in Korea.

Juvenile xanthogranuloma (JXG) is an uncommon histiocytic cutaneous lesion. An 18-month-old girl visited our clinic due to rapid growing orange-yellowish lesion on scalp. Enlarging time from 1 mm to 12 mm was just 8 weeks. We excised the tumor and adjacent normal tissue. Histopathological study showed numerous eosinophils and Touton giant cells within the lesion. Immunohistochemical study revealed positive immunoreactivity for CD68 in most areas. No recurrence was seen during 12 months after resection. We report a case with rapidly growing JXG on scalp with peculiar histopathologic findings.

Angioleiomyoma is a benign soft tissue tumor originating from vascular smooth muscle. We report a case of a 20-year-old student who presented with pain in the right shoulder of 4 years duration. Shoulder movements were pain-free throughout the range of motion except resisted external rotation. Magnetic resonance imaging visualized a well-circumscribed lesion over the infraspinatus tendon. The lesion was surgically removed and sent for histopathological analysis. Morphology and immunohistochemistry results were suggestive of angioleiomyoma. The most common location for such a lesion is the lower limb, with less than 1% being reported in the upper arm, of which an angioleiomyoma of the shoulder is extremely rare.

Purpose: Morel - Lavallee lesions is post - traumatic effusion at subcutaneous layer. Early management of Morel - Lavallee lesion is percutaneous drainage and compression. Surgical excision is recommended for cases that are chronic. Method: 41 - year old male patient had slow growing, painful mass on left thigh, which has been present for 3 years. He had a history of blunt trauma 3 years ago. Computed tomography presented $10{\times}10{\times}5cm$ sized cystic mass on left thigh, between subcutaneous fat layer and muscle fascia layer. The mass was surgically removed and biopsy was performed. Result: Histopathological examination shows chronic inflammation and fibrotic change. After 6 month follow - up period, postoperative course was uneventful. Conclusion: We performed surgical excision of Morel - Lavalle lesion in a patient who had trauma 3 years ago. We report a case of Morel - Lavallee lesion with the review of the literatures.

The livers of 300 cases of Korean native cattle which were collected at slaughted house in Pusan were examined by gross and histopathological means to study patterns of pathological changes of the organ. 1. The most dominated lesion of the liver was those of fascioliasis showing incidence rate as 907 per cent of inspected cattle. 2. On age distribution of the fascioliasis lesion in the liver, higher incidence was seen in animals that were from 6 to 9 years of age. 3. Significant changes of the hepaticparenchyma caused by immature flukes included thrombosis, migrational tracks such as hemorrhagic foci with massive eosinophilia and hepatic necrosis. The changes of chronically infected livers of cattle were recognized as proliferation of periductal eosinophilic granuloma of various degrees in each portal triad. And this easential cholangiohepatitis might develop into multiple focal cirrhosis or diffuse perilobular cirrhosis. 4. Most cases with gross lesion of swelled bile ducts on visceral surface of the liver showed histological evidences of fascioliasis lesion throughout hepatic lobes.
