Background Epidermal cysts are commonly occurring masses usually less than 5 cm in diameter, but in predisposed patients, epidermal cysts can grow relatively large due to chronic infection. Methods From June 2002 to July 2010, 17 patients received 19 regional perforator-based island flaps to cover defects due to the excision of large epidermal cysts (diameter >5 cm) in the buttocks. Eight patients had diabetes, and seven had rheumatoid arthritis. The pedicles were not fully isolated to prevent spasms or twisting. Results All the flaps survived completely, except for one case with partial necrosis of the flap, which necessitated another perforator-based island flap for coverage. There were two cases of wound dehiscence, which were reclosed after meticulous debridement. There were no recurrences of the masses during follow-up periods of 8.1 months (range, 6-12 months). Conclusions In patients with large epidermal cysts and underlying medical disorders, regional perforator-based island flaps can be the solution to coverage of the defects after excision.

Marsupialization and decompression constitute a well-established procedure for treating cavitary bone lesions of the jaw. The technique can be a primary treatment option, especially for pediatric patients with large cysts or lesions involving vital anatomical structures, such as a developing tooth germ. In this procedure, a decompression stent, such as a customized acrylic obturator or space-maintaining appliance, silicone tube, or nasal cannula, is inserted to maintain the patency of the cyst. However, this may cause clinical problems, such as irritation or trauma to the adjacent tissues, as well as discomfort to the patient, or failure of the stent due to cyst shrinkage. It can also be a reason for patient noncompliance. In the cases described here, a minimally invasive marsupialization technique using a metal tube made from a 16-gauge needle was used for odontogenic cysts in pediatric patients associated with unerupted teeth. Through this method, the lesions were removed, with patient cooperation, and the cyst-associated teeth erupted spontaneously.

Nasopalatine duct cyst(NPDC) is the most common non-odontogenic cyst in the oral area and is thought to be originated from the epithelial remnants of the nasopalatine duct. Many etiologic factors have been proposed for the NPDC; trauma to the region during mastication or from ill fitting dentures, bacterial infection, and spontaneous proliferation of tissue. The majority of cases are seen between the ages of 40th and 60th and it is rare in children. Surgical enucleation is the recommended treatment for NPDC, usually under general anaesthesia. A 9-year-old boy was refered to the chosun university pedodontics clinic that this child who has anterior palatal swelling is in routine check. In this case, swelling was presented at the bottom of the anterior nasal cavity as well as in the labial aspect of the upper alveolar ridge. It was so large that we treated it by marsupialization and obturator was put. This patient is on the continuous observation. We treated the child who had NPDC by marsupialization, and got the successful results such as rapid bone regeneration and the consistency of incisor vitality.

Aneurysmal bone cyst(ABC) is a benign lesion and generally occurs in the long bones and vertebral column. ABC of the rib is an uncommon entity. We reported a case of ABC originating in the left first rib. The patient was a 19-year-old woman and presented with palpable mass on the shoulder. Chest X ray and MRI showed a large expansile mass, with multiple cystic areas, arising from the left first rib and bulging out into retroclavicular and paravertebral soft tissue, so the lesion was initially misdiagnosed as a soft tissue malignant tumor destructing adjacent rib. On histological examination, the mass, which was surrounded by a peripheral band of mature trabecular bone, consisted of multiple anastomosing cavernous blood channels separated by fibrous septa that containing osteoid, myxochondroid material and osteoclast-type giant cells.

The conclusions which was acquired one renal cell carcinoma and renal disease 132 cases that was tested renal echogram among 4,499 cases for recent 16 months at medical department, Dae Han Kyoyuk Insurance company from August, 1984 to November, 1985 are as follows: 1. On bur ultrasonography, the echo of tumor was demonstrated with echogenicity as compared with renal parenchyme. 2. The case was stage I by Robson's modification method for pathologic histology. 3. There is no fever, typical triad of renal cell carcinoma and the result of serum biochemical test was within normal limit. 4. The frequency with disease was renal cell carcinoma(0.76%), ureteral stone(1.5%), multicystic kidney(2.27%), hydroureter(2.27%), Bilateral poly cystic kidney(4.55%), hydronephrosis(4.55%), renal agenesis(6.06%) renal calculi(18.18%), simple cyst(60.61%). 5. The frequency with age was 55/1200 case(4.58%) in $41{\sim}50$ years, 13/296 cases(4.39%) in $51{\sim}60$ years, 43/2144 cases(2.01%) in $31{\sim}40$ years, 14/791 cases(1.77%) in $21{\sim}30$ years, 7/53 cases(1.32%) more than 61 years and 0/15(0%) under 20 years. 6. The affected site of renal agenesis 8 cases was right side all. 7. In total renal disease 132 cases, the affected site of 126 cases except bilateral polycystic kidney 6 cases was right kidney 72 cases, left kidney the proportion of right to left 1.6:1 8. In total renal disease 132 cases except bilateral polycystic kidneys 6 cases, the patients affected with both side kidneys were 14 cases. 9. The affection rate with sex in total renal disease 132 cases was 98/2860 cases in male, 34/1819 cases in female and the former was about 2 times than the latter. 10. Classifying the stone with part, nephrolithiasis 24 cases were appeared high frequency, on the contray, ureteral stone 2 cases. 11. 2 cases of ureteral stone developed complication, hydronephrosis and hydroureter. 12. The linear array type transducer was not helpful for the diagnosis of lower ureteral calculi but for the lower ureteral calculi, we could see the stone with high echo in accompanying with acoustic shadowing. 13. In 24 cases of renal calculi, both side nephrolithiasis was 3 cases(12.5%). 14. In renal calculi, solitary stone could be seen extremely much and the number of stone was so much variable from 2 to 10. 15. In 26 cases with renal calculi and ureteral stone, the common clinical manifestation was a intermittent and slight pain. 16. In 80 cases of renal cyst, as one's get older, the affection rate of cyst extremely rised. 17. In bilateral polycystic kidney, large cyst had septum on the whole. 18. The patients with complication were 14 cases(10.6%) of total patients.

This study was designed 1) to compare the distributions of periapical inflammatory cells and 2) to identify lymphocytes and compare the lymphocyte distribution with T lymphocyte subpopulation and then 3) to examine the distribution of cycling cell in human dental periapical lesions. From each of the twenty-five human dental periapical lesions observed one small portion was fixed, embeded in paraffin, sectioned serially and stained with HE. The periapical inflammatory cells were counted to obtain the relative concentration of lymphocyte, plasma cell, macrophage and neutrophil. The large part of each lesion was analysed using Flow cytometer and monoclonal antibodies to obtain the relative concentration of T lymphocyte, B lymphocyte, T'helper cell and T suppressor/cytotoxic cell. In addition to that, seven human dental periapical lesions were examined with DNA analysis to observe the distribution of cycling cell. Following results were obtained: 1. 24 cases of the 32 periapical lesions examined were diagnosed as periapical granuloma and the remaining 8 cases as periapical cyst. Lymphocytes comprised 42.1% of total inflammatory cells in periapical granuloma and 41.8% in periapical cyst. Corresponding percentages for macrophages were 33.8% and 30.3%; for plasma cells, 15.9% and 19.0%; for neutrophils, 8.2% and 8.8%. 2. All of the periapical lesions examined had T lymphocyte, B lymphocyte, T helper cell, T suppressor/cytotoxic cell. And in all cases, T lymphocytes were observed predominantly more than B lymphocytes. 3. In 2 cases of the control group only T lymphocytes were found, and in the remaining 2 cases T lymphocytes were observed predominantly. 4. T helper cells were observed predominantly more than T suppressor/cytotoxic cells in all cases of perapical granulomas. 5. T suppressor/cytotoxic cells were observed predominantly more than T helper cells in 4 cases of periapical cysts (total 5 cases were examined) and only in one case T helper cells were more than T suppressor/cytotoxic cells. 6. In control group, T helper cells were predominant in 2 cases and T helper cells were equivalent to T suppressor/cytotoxic cells in one case. In remaining one case T suppressor/cytotoxic cells were predominant. 7. As the result of DNA analysis, the average proliferating indices of the various groups examined were measured as follows: in the control group 5.45%, in periapical granuloma 6.64%, in periapical cyst 10.1%. The highest index was observed in periapical cyst.

Ovaries of 21 bitches presented with gynecopathies were surgically removed and histologically examined. Standard histological, as well as immunohistochemical, classification of 193 cystic structures resulted in the classification of 72 cysts of subsurface epithelial structures (SES), 61 follicular cysts (FCs), 38 cystic rete ovarii (CRO), 13 lutein cysts (LCs), and 9 non-classifiable cysts (NCCs). In addition to the histological classification, results were interpreted according to subject medical history, clinical examination outcome, and macroscopic observations during ovariohysterectomy. Dogs with ovarian cysts (OCs) and associated reproductive perturbations were mostly nulliparous, of large breed, and had an average of $9.5{\pm}3$ years. Prolonged or shortened inter-estrus intervals of past heats, however, seemed to be relatively low-risk factors for the development of OCs in dogs. Furthermore, we provide histological observations of a rarely seen canine LC including a degenerated oocyte in the central cavity.

Purpose: This study was aimed to evaluate the result of inlay cortical strut bone grafts for large cysts or cavitary bone lesions in long bones. Materials and Methods: Seven patients with large cyst or cavitary bony lesions were managed with curettage, allogeneic inlay cortical strut and cancellous bone grafts. Additional plate and screw fixations were performed in 6 patients. There were three SBCs, two FDs with secondary ABC changes, one FD and one post-cement spacer removal state. Three of them had pathologic fractures. Progression of bone healing and mechanical support and functional result were evaluated. The mean follow-up period was 25.4 months. Results: Incorporations into host bones were progressed in all, average 4.2 months in six metaphyseal regions and 5.8 months in five diaphyseal regions respectively. Full structural supports were achieved in all except one patient without any additional procedures. No allograft-related complication was developed. Mean functional score according to the MSTS criteria was 29.6 at last follow up. Conclusion: Inlay cortical strut graft provided additional mechanical stability and bone stock for screw purchase in large cyst or cavitary defects of long bones, which allow early mobilization and excellent functional outcome.

Ichthyophonus disease broke out among rainbow trout (Salmon gairdneri) fry in November 1979, and after that a fish group containing diseased fish was kept for one year. The authors examined histopathologically the diseased fish 3 times, at 6 momths intervals. Diseased fish showed markedly stunted growth and darkish coloration, and anatomically the liver with small white nodules, the heart with red nodules, the spleen with granular nodules and the markedly tumefied kidney. Ichthyophonus invaded various tissues in the host and took the shape of multinucleate spherical or hyphal body. The multinucleate-spherical bodies contained many nuclei with a large nucleolus and granular cytoplasm. Histopathologically systemic dissemination and systemic proliferation by Ichthyophonus sp. wire indentified. In addition to a single multinucleate-spherical body appeared in the various tissue, large granulomas containing two to several generations of Ichthyophonus sp. were formed especially in the liver, kidey and spleen. The inflammatory response against Ichthyophonus was characterized by mononuclear-celluar proliferation with giant cell formation and fibrobasts proliferation.

An abnormal Korean native cow of six years old with extra legs was observed macroscopically and radiographically. The results were summarized as follows; 1. External features included two normal forelimbs and hindlimbs, and two extra forelimbs which were underdeveloped. The extra forelimbs of different length attached laterally to the cranial regions of neck on right scapula. 2. The large extra forelimb had scapular meromelia. It consisted of underdeveloped humerus, antebrachial skeleton, several carpal bones, metacapal bone(MC3+4) and two digitis with each pairs of hoof and a rudimentary hoof of dewclaw. 3. The small extra forelimb had scapular and antebrachial meromelia. It consisted of underdeveloped metacarpal and carpal bone, severely deformed humerus, fused carpal bones, and two digitis with two hooves, and a rudimentary hoof of dewclaw. 4. The dermoid cyst was observed between the large and small extra forelimbs.
