  • A 7-year-old castrated male Cocker spaniel dog was referred to Gyeongsang National University Veterinary Medical Teaching Hospital with a severe abdominal distension. A huge, inhomogeneous fat opacity mass was identified on the abdomen radiographic survey. From the abdominal ultrasonographic examination, the mass was found to have irregular marginated hyperechoic capsule with cellular hypoechoic fluids inside. On the computed tomography, an encapsulated inhomogeneous mass was identified with fat attenuation peripheral and soft tissue attenuation inside. The origin of the mass was confirmed as falciform fat by surgical excision. The resected mass appeared to be a firm reddish-brown color with a smooth surface. The histopathological appearance was a well-differentiated liporsarcoma. The patient has no recurrent signs 1 month after surgery.

  • Purpose: We evaluated oncologic outcomes of chondrosarcomas and analyzed the disease-free survival rate of chondrosarcomas according to the various factors. Materials and Methods: We performed a retrospective study for the disease-free survival rate of 48 chondrosarcomas, 44 of which underwent surgical treatment and followed up more than 18 months since 1993, and in the remaining 4 cases, the patients died before 18 months after surgery. The vsariables were location, tumor volume, histologic grade, stage, age at presentation and treatment performed. The mean follow up period was 43.8 months (1-196 months). Results: The overall disease-free survival rate was 77.1% at mean 43.8 month follow up. The 5 year- and 10 year disease-free survival rates were 64% and 58% respectively. The histologic grade, stage, age at presentation revealed statistical significance on disease-free survival. All 9 patients treated with extended curettage for grade 1 central chondrosarcomas revealed disease-free survival with excellent functional outcome. Conclusion: The disease-free survival rate of chondrosarcomas mainly depended on histologic grade, stage and age at presentation. Local recurrence and distant metastasis also revealed statistically significant differences of disease-free survival rate. Comparing to wide resection, extended curettage for low-grade central chondrosarcomas in extremities were efficient methods with similar survival rate and less functional losses and complications.

  • Pilomatricoma is a benign soft tissue tumor of hair follicle origin. They occur most commonly in the head and neck region and are usually found in girls during the first two decades of life. Although malignant transformation has been described, it is exceedingly rare. The clinical presentation is typically that of an asymptomatic, superfical, solitary, firm mass that is often accompanied by a reddish-blue discoloration of the overlying skin. Histopathologically pilomatricoma are seen as epithelial islands embedded in a cellular stroma. The epithelial component consist of two main cell types : basaloid cells and ghost cells. Intracellular and stromal calcification is reported in many cases. Diagnosis is usually suspected based on palpation of a superficial, rock-hard mass and confirmed by histopathologic examination. Surgical excision is both curative and the treatment of choice. Recurrence is rare. In this case, the radiographs showed a dense calcification, measuring about 1cm diameter. So simple excision was peformed intraorally, and resultantly the lesion was proved to be a pilomatricoma by histological examination.

  • Plant regeneration system from floral stem of Mymphoides indica via somatic embryogenesis was established. After four weeks of culture onto 1/2MS medium containing 2,4-D, pale-yellow globular structures and calluses were formed on the cut surface of floral stem explants. Upon transfer to 1/2MS basal medium, pale-yellow globular structures were developed into somatic embryos and normal plantlets. These results indicated that pale-yellow globular structures and calluses from floral stem were globular embryos and embryogenic calluses, respectively. The frequency of embryogenic callus formation from floral stem was reached to nearly 100% when floral stem was cultured onto 1/2Ms medium supplemented with low concentration of 2,4-D (0.1 to 0.3 mg/L). However, the higher concentration of 2,4-D resulted in decrease of the frequency of embryogenic callus formation. In this study, low concentration of 2,4-D had a stimulative role in embryogenic callus formation, whereas BA showed inhibitory role in callus formation. In comparison to floral stem, leaf explants showed low frequency of embryogenic callus formation. The highest frequency of embryogenic callus formation from leaf explants was 9.5% when leaf explants were cultured onto 1/2MS medium supplemented with 0.3 mg/L of 2,4-D. The plant regeneration system of Nymphoides indica established in this study, might be applied to mass proliferation, conservation of genetic resources and genetic transformation for molecular breeding.

  • A FA intersectional hybrid lily cultivar 'Golden Center' was developed in 2008 at National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA) Korea. The cross was conducted between female parent Lilium FA hybrid 'Migreen (FA97-30)' and male parent L. Asiatic hybrid 'Sanzio' by a cut style pollination method (CSM) and immature embryo rescure at Suwon in 1999. The first selection was done and the line name was tentatively given as 'FA04-24' in 2004. After in vitro multiplication, bulb-producing ability, line, growth and flowering characteristic of 'FA04-24' were evaluated from 2005 to 2007. The evaluation of characteristics and consumer preferences were surveyed at a lily flower show of NIHHS in 2008. 'Golden Center' flowers in the middle of June and grows up to 144 cm high in length. Flower blooms facing upward, with light yellow petals (RHS, GW157C). The pollen of 'Golden Center' is sterile. Year-round flowering can be done by storing the bulb under $-1.5^{\circ}C$ conditions. It is needed to control Botrytis disease in wet season.

  • Fibrous dysplasia is a skeletal developmental anomaly of the bone-forming mesenchyme that manifests as a defect in osteoblastic differentiation and maturation. It is a nonhereditary disorder of unknown cause. In fibrous dysplasia, the medullary bone is replaced by fibrous tissue, which appears various imaging findings. It is usually an incidental finding, generally not requiring further investigation. However, fibrous dysplasia may be complicated by pathologic fracture, and rarely by malignant degeneration. We present the image findings of a 44-year-old man who had a chondroblastic osteosarcoma arising from polyostotic fibrous dysplasia in the femur. Evidence of cortical destruction on plain radiography and soft tissue mass in the lesion on MR images suggested a tumor of malignant transformation.

  • In the study of investigate the expression and effects of adrenomedullin (AM) in the tissue injured by ethanol in our laboratory, there were lymphosarcomas involving mesenteric lymph node and intestine discovered in experimental mice. Lymphosarcoma is probably the second most common spontaneous neoplastic disease, the incidence of which is dependent on the strain of mouse. The diagnosis of lymphosarcoma was based on gross and light microscopic studies. Crossly, the excised intestine and mesentery showed soft-to-firm, cream-colored, displayed protuberance into the lumen. The neoplastic cells had mainly infiltrated into the mucosal and mesenteric lymph node, and have round hyperchromatic nuclei and a small amount of cytoplasm. The origin of these tumor cells was determined by immunohistochemistry positive of CD20, CD3 and Vimentin.

  • Purpose: We analyzed the oncologic characteristics and outcome of patients with inflammatory myofibroblastic tumor of extremities. Materials and Methods: Among the soft tissue tumor patients who were treated between 1999 and 2012, 5 patients who were pathologically confirmed as the inflammatory myofibroblastic tumor of extremities were analyzed retrospectively. Results: There were 1 man and 4 women with mean age of 44 years (37-55 years). The average follow up was 34.6 months (8-87 months). All patients underwent surgical treatment. Only 1 patient had wide resection margin and remaining 4 had marginal (3) or intralesional (1) resection margin. All of 4 patients without wide resection margin developed local recurrence at 10.3 months (8-19 months). Malignant transformation to fibrosarcoma was occurred in 2 patients who developed local recurrence, and 1 patient developed multiple metastases to lung, liver and lymph nodes and expired at 37 months. Three of 5 patients had tumor location abutted to or invasion to major arteries and 1 patient had tumor invading sciatic nerve. Conclusion: It is observed that inflammatory myofibroblastic tumor of extremities is usually located near the major neurovascular structure. Wide resection should be considered as the initial surgical treatment because this tumor showed a high local recurrence rate and possibility of malignant transformation.
