Lymphangioma is a rare benign congenital tumor of the lymphatic system, which is commonly diagnosed before 2 years of age. In the natronal report, cystic lymphangioma was usually reported as a huge translucent mass located in the head and neck area. It's occurrence in retropharyngeal space with respiratory obstruction and swallowing difficulty in neonate is extremely rare and postoperative nasopharyngeal reflux has rarely been reported. Complete resection is the standard therapy. However, involvement of the upper airway may be determining prognosis in the extensive lymphangiomas because of the difficulty of complete excision. We present a case of cystic lymphangioma in neonate which was initially asymptomatic but gradually progressed to cause respiratory obstruction due to enlargement. After resection, nasopharyngeal reflux developed with dysfunction of the soft palate and gradually improved with conservative care over 5 months.

An 8-year-old male red fox (Vulpes vulpes) in Species Restoration Technology Institute of Korea National Park Service (KNPS), revealed nodular growths in its ventro-cervical region. The fox was introduced from Young-Yang Gun in 2012 to KNPS for re-introduction of the red fox. It has been cared in captive facility and showed the mass in August 2013 that was sent to Wildlife Medical Center. For the diagnosis of underlying disease and cervical mass, radiographical and sonographical examinations, complete blood count, serum chemistry analysis, peripheral blood smear examination and surgical removal of the mass were performed. The mass was fixed in 10% neutral buffered formalin and processed routinely for haematoxylin and eosin (HE) stain. Based on hematological and serum chemical examination, the fox showed mild leukocytosis, thrombopenia, increase of creatine kinase MB (CKMB) and uric acid. However, it was considered as no clinical relevance since the fox showed no related clinical signs. Macroscopically, the mass was round shape, whitish and well-demarcated. Microscopically, it was diagnosed as a lipoma consisting of mature adipose tissue. Lipoma is a common benign tumor in most domestic animals, however it has never been reported in the red fox. The present case report provides comprehensive diagnosis of a subcutaneous lipoma in a red fox.

Though thymoma is considered benign In a histopathologic specimen, its unusual behavior makes it important for surgeons to manage this neoplasm as cancerous lesion. Hence we clinically analysed the surgical cases of thymoma in our hospital, And we suggest the risk factors for its prognosis From January 1987 to December 1994, we experienced 41 surgical cases of thymoma, excluding thymic carcinoma and cysts. There were 21 male and 20 female; age ranged from 16 to 64 years. Among them, myasthenia gratis was present in 22 patients(53.7%). Surgical treatment consisted of complete resection in 31 patients, partial resection In 7 patients, and biopsy only in 3 patients. According to Masaoka's classification, there were 27 patients in milage 1, 4 patients in stage II, and 10 patients In stage III. Histopathology was of epithelial type in 14 patients, Iymphocytic type in 11, and mixed type in 19. Eleven patients had adjuvant radiotherapy, chemotherapy, or b th and there was no surgical mortality. Postoperative follow-up ranged from 1 to 88 months (mean )6 months) and three patients died and 5 patients suffered recurrences during the follow-up period. Postoperative risk factors were advanced Masaoka stage, invasiveness, and surgical method.

Introduction : $^{99m}Tc$-(V)-DMSA is a tumor seeking agent that has been used to image medullary carcinoma of thyroid, soft tissue sarcoma and lung cancer. This study was designed to assess the clinical role of $^{99m}Tc$-(V)-DMSA in the diagnosis of head and neck cancers. We has evaluated the diagnostic efficacy of planar and SPECT imaging using $^{99m}Tc$-(V)-DMSA. Patients and Method : Sixty-eight patients with head and neck mass were included in this study. All subjects were diagnosed by biopsy or surgery. Planar and SPECT images were obtained at 2 or 3 hour after intravenous injection of 740 MBq(20 mCi) $^{99m}Tc$-(V)-DMSA. Seventeen patients also underwent SPECT in aging using dual head camera. Result : The diagnostic sensitivity of $^{99m}Tc$-(V)-DMSA planar and SPECT imaging was 65% and 90%, and specificity was 80% and 66%, respectively. The sensitivity of planar imaging in squamous cell carcinoma was similar to overall sensitivity Six metastatic lesion were first diagnosed by scintigraphy. But benign lesions such as Kikuchi syndrome, tuberculous lymphadenitis also revealed increased uptake. Conclusion : $^{99m}Tc$-(V)-DMSA imaging seems to be a promising method in the evaluation of patients with head and neck mass. We recommend SPECT imaging to delineate anatomic localization of the lesion.

Lipoma is a common neoplasm in soft tissues. However, an intrapulmonary lipoma is a rare benign tumor. Patients with a bronchial lipoma might have a malignant potential related to their smoking history due to the case reports of lung cancer accompanied with lipoma. Endobronchial lipoma can cause irreversible parenchymal lung damage if not diagnosed and treated early. Therefore, it should initially be treated by fiberoptic bronchoscopy or surgery depending on the status of distal parenchymal lung damage. Bronchiolitis obliterans with organizing pneumonia (BOOP) is a pathological syndrome that is defined by the presence of buds of granulation tissue consisting of fibroblasts and collagen within the lumen of the distal air spaces. BOOP is caused by drug intoxication, connective tissue disease, infection, obstructive pneumonia, tumors, or an unknown etiology. We encountered a 58 year-old male patient with endobronchial lipoma, causing the collapse of the right middle and lower lobes, and BOOP due to obstructive pneumonia.

Pigmented villonodular synovitis (PVNS) is a rare proliferative disease involving synovial membranes. Natural history and etiology of PVNS are not well known. PVNS presents as localized or diffuse tumor like nodular lesion of the synovial lining of the joint and the synovial spaces adjacent to the joints. Though histologically benign, it is a very aggressive lesion, capable of bone destruction and widespread infiltration of surrounding tissues. Standard therapy is surgical resection, but due to the infiltrative growth, the recurrence rate is significantly high. After several relapses surgical treatment of diffuse PVNS becomes difficult and may require amputation of the involved limb. Radiotherapy can provide an effective treatment option for patients with large lesions or lesions which are not suitable for surgery, after incomplete resection to prevent relapses or to avoid amputation. We report 2 cases of diffuse PVNS in the knee joint treated with arthroscopic gross total synovectomy and radiotherapy.

Odontoma is defined as a benign odontogenic tumor containing enmel, dentin as well as cementum. It has come to mean a growth in which both the epithelial and the mesenchymal cells exhibit complete differentiation. Most authorities accept the view today that the odontoma represents a hamartomatous malformation rather than a true neoplasm. The etiology of odontomas is uncertain but hypothesized to involve local trauma, infection, inheritance or mutant gene. The odontomas often cause various disturbances in the eruption and position of the teeth. The steps in removal of an odontoma in close relation to an adjacent impacted normal tooth should comprise 1) removal of odontoma and 2) exposure of the impacted tooth. Orthodontic therapy may be applied. Before treatment, the necessary space for the impacted tooth should be evaluated. If there is lack of space in the dental arch, orthodontic treatment should be carried out before operation.

The purpose of this comparative study is to find out women and their spouses' sexual life and the factors affecting on their sexual life after women's hysterectomy. The data were the 110 questionaires which were collected from the participants, the 55 women who had undergone a hysterectomy due to gynecologic disease or benign tumor of genital organs and their spouses from January 1, 1999 to January 30, 2002 in one general hospital located in Seoul, Korea. Questionnaires were mailed to couples, who agreed to participate on the study and self reported questionnaires returned in the pre-stamped envelopes. And personal visits were made for those couples who did not respond. Tools for Sexual life and characteristics of sexual activities were reconstituted by the author based on Kim(1996) and Chang(1988)'s tools and were reviewed by a nurse specialist. Data analysis was done by SPSS 10.0 program using frequency, percentage, mean, S.D. Pearson correlation coefficient, t-test, oneway ANOVA and multiple regression. The results of this study are as follows; 1. Of all female subjects, 80% had experienced hysterectomy below the age of 50. 2. 72.8% of female subjects and 67.3% of male subjects did not receive any sexual education & counseling before and after the surgery. More than 60% of both female and male subjects answered that it was necessary to have a sexual counseling. And 40% wanted to receive sexual counseling from a professional sexual counselor. 3. More than half of couples started their first coitus within 4 weeks after the surgery. And 88.9% of females and 85.2% of males answered that they were experiencing orgasms with their sexual relationship. 4. Influencing factors on the satisfaction level of sexual life were couple's intimacy and sexual discomfort in women and couple's intimacy and sexual knowledge in spouses. These factors explained the 33% and 24% of total variance respectively. In conclusion, the result suggests that it is necessary for couples to receive a professional sexual education and counseling to improve couples' quality of life. It is also necessary for institutions to use prepared nurses by receiving sexual counseling and education program as a professional sexual counselors or educators so as to provide individualized sexual education and counseling for their clients.

Purpose : The purpose of this study was to evaluate the diagnostic accuracy of 3.0-T breast MRI for detecting additional breast cancer soon after the initial diagnosis of breast cancer. Materials and Methods : From March to June 2009, 101 patients recently diagnosed breast cancer underwent breast MRI and surgery. Parameters analyzed on MRI were total extent of tumor, suspicious findings of multifocal, multicentric, or contralateral cancer. The diagnosis of MRI-detected cancer was confirmed by means of biopsy or surgical specimen evaluation after the localization. Results : MRI showed 37 additional suspicious findings in 34 patients. Twenty nine findings were true-positive (29/37, 78.4%), including 16 cases of multifocality, 11 cases of multicentricity and 2 cases of contralateral cancer. Among these cancers, 13 (44.8%) were ductal carcinoma in situ (DCIS) and 16 (55.1%) were infiltrating cancer. Eight findings were false-positive (8/37, 21.6%) including 6 cases of benign disease and 2 cases of high-risk lesions. Conclusion : In women with recently diagnosed breast cancer, 3.0-T MR imaging showed additional suspicious findings in 33.7%. The sensitivity and specificity for detecting additional breast cancer was 100% and 89.3%, respectively.

Background : Lymphangioma of the mediastinum is an uncommon benign tumor of lymphatic origin that is most often seen in children, is very rare in adults and is frequently discovered incidentally on chest x-ray exams. While radiology (CT and MRI) may suggest the diagnosis and allow an assessment of the operative difficulties, the histology of the surgical specimen is required for precise diagnosis. Complete resection is the only treatment; however, in some patients resection was incomplete because of the infiltrating character of these tumors, leading to recurrence. We report three cases of mediastinal lymphangioma with a review of the literature.
