Background: Lipomas are benign soft tissue neoplasms of mature adipose tissue commonly occurring in the trunk or extremities. But, intraoral lipomas are rare entities which may be only noticed during routine dental examinations. Especially intramuscular lipomas on the tongue have been reported very rarely. In this study, we report a case of intramuscular lipoma on tongue, with a review of the literature from 1978 to 2019, providing data on age, gender, location, presenting symptoms, size, surgical methods, and recurrence. Case presentation: A case of intramuscular lipoma occurring in tongue region in a 65-year-old male is reported. Surgical excision is the mainstay of treatment for the lesion. In order to decrease the deformity and discomfort after the excision, we tried to modify surgical technique using enveloped mucosal flap. This technique provided more comfortable healing procedure on the operative site without recurrence. Conclusion: This is a rare case of large intramuscular lipoma on tongue. Surgical excision with enveloped mucosal flap design was performed to diminish postoperative raw surface and discomfort and a 24-month follow-up showed excellent healing without any recurrence. A case of intramuscular lipoma on tongue and relevant literature reviews are presented in this study.

Lipoblastoma is a rare benign neoplasm occurring exclusively in children below the age of three years. It affects chiefly the upper and lower extremities, and less commonly head and neck area, trunk, mediastinum, mesentery, and retroperitoneum. We present two cases of lipoblastoma occurring in the mediastinum of a 21-month-old boy and in the back of a 15-month-old boy. The characteristic features of Fine needle aspiration cytology smears were the presence of immature fat cells in the form of spindle-shaped cells, stellate cells and vacuolated lipoblasts along with lipocytes against a myxomatous background. Two tumors were histologically confirmed to be lipoblastomas. Lipoblastoma can be cytologically diagnosed by considering the cytologic findings and the age of the patient.

Malignant triton tumor(MTT) is a rare type of malignant peripheral nerve sheath tumor(MPNST) with focal rhabdomyoblastic differentiation. MTT constitutes about 5% of all MPNSTs and described the first case of a MTT in a patient with Von Recklinghausen disease by Masson in 1932. MTT is commonly seen in the head, neck, extremities and trunk. It can occur in sporadic form or over a setting of neurofibromatosis-1(NF-1). The diagnosis can be confirmed based on morphologic grounds supported by an immunostain such as S-100 protein. Desmin, myo-D1 and myogenin are immunostains positive for rhabdomyoblasts. MTT has an aggressive biological behavior so prognosis of this rare and highly malignant tumor is poor and optimal treatment remains unclear. But modern treatment consisted of radical excision and postoperative radiotherapy has improved the prognosis of such cases.

Objectives: This study aims to report a case of chronic nummular dermatitis improved by Hwangryunagyo-tang. Methods: The patient in this study was a 15-year-old female, who visited our hospital with symptoms such as redness, erythema, papule, excoriation, scale, exudation, crusting, lichenification, and pruritus of the extremities and trunk. Considering that the skin lesions were coin-shaped and persisted for more than 6 months, the patient's symptoms were diagnosed as chronic nummular eczema. Based on the patient's symptoms and overall condition, Hwangryunagyo-tang was prescribed. Results: Approximately 4 months after administration of Hwangryunagyo-tang, the exudate disappeared, and overall skin symptoms improved, from objective score 33.7 to 6.6, leaving only slight scale, dryness, and pigmentation. As the pruritus of the skin lesion decreased from numeric rating scale 8 to 1, the patient's sleeping condition also improved from numeric rating scale 9 to 0. Conclusion: This study is significant in that the symptoms of chronic nummular dermatitis were effectively improved after administration of Hwangryunagyo-tang.

Purpose: Paraquat is the most commonly used herbicide in Korea. Exposure to paraquat through the skin has resulted in local irritation or inflammation of varying degree, sometimes severe. The purpose of this study was to review the patients with paraquat poisoning by skin absorption. Methods: We analysed retrospectively the clinical and laboratory findings of 45 patients with paraquat poisoning after dermal exposure, who were admitted to Soonchunhyang University Cheonan Hospital from January 1999 to December 2003. Results: Among 870 cases of paraquat poisoning, 45 cases were exposed to paraquat through the skin. The peak incidence was the fifth decade($40\%$). The clinical symptoms were pain, pruritus, nausea, and vomiting. The major skin lesions were generalized vesicobullae and necrotic erosion in face, scrotum, trunk, upper and lower extremities and etc. All patients were survived after skin contact or inhalation of paraquat. Conclusion: This study illustrates the extreme toxicity of paraquat and demonstrates that lethal quantities of paraquat may be absorbed if repeated exposure to it. Stricter precautions, including the mandatory use of protective clothing, should be recommended whenever this material is used.

Unlike production line works, construction work is non-repetitive in nature. In this study, a checklist was developed to characterize the ergonomic hazards of construction work. Eight existing checklists including OWAS, RULA, and REBA were integrated, and a new version was designed to include more postures of lower extremities. The analysis results obtained using the new checklist showed that manual materials handling (MMH) is the most common risk factor. About 62% of the MMH was done below the knee level or above the elbow level, and 22% was carried out with the trunk twisted more than $60^{\circ}$. The next risk factors were the works done with the knee bent or squatted, or with the shoulders abducted. It can be concluded that the new checklist is successful as a quick and easy tool for screening risk factors of construction works, although it is not capable of determining action levels. Further studies on validation of the checklist are expected.

The pelvic girdle function as an integrated unit with all three bones moving at all three joints, are influenced by the lower extremities below and vertebral column and trunk above sacroiliac movements are caused by spinal motion, whereas iliosacral movements are caused by movements of the lower limbs. Concept of normal functional integration among the lumbar spine, pelvic and hip joint is basic to the understanding of dysfunction in this region and also functional movement of the lumbo-pelvic-hip region are part of the clinical examination, consequently the integrated biomechanics of these region need to be understood. The purpose of this review is to ascertain the integrated biomechanics among the lumbo-pelvic-hip complex by consideration of literature and to give sufficient information to be able to render accurate assessment and treatment for the syndromes described.

The malignant peripheral nerve sheath tumor(MPNST) is an extremely rare soft tissue sarcoma of ectomesenchyme also known as malignant schwannoma or malignant neurilemoma. It is a highly malignant sarcoma, which is locally invasive, frequently leading to multiple recurrences and eventual metastatic spread. The peak incidence of this disease is known to arise in the seventh decades. In human body, trunk and extremities are the most commonly involved sites, and only 8-14% of all lesions appear in head and neck region. Because immunohistochemical staining is essential in final diagnosis. The authors report a case of malignant peripheral nerve sheath tumor in neck with hypopharyngeal cancer simultaneously on a review of the literature.

The malignant fibrous histiocytoma was the most common soft tissue sarcoma in late life adult. It was first described in 1964 by 0' Brien and Stout. It's histiogenesis had been considered to be of histiocytic origin. It Involves the extremities, retroperitoneum and trunk. It usually metastasizes to the lung. but primary lung lesion is extremly rare and it's prognosis was poor. We have experienced a case of MFR, which was confirmed by open lung biopsy. So we report a case of MFR of the lung with review of literature.

데스모이드 종양은 섬유아세포양 증식을 특징으로 하는 심부 섬유종증으로 조직학적으로 양성이지만 침습적인 성장 양상과 높은 재발율을 보인다. 방사선학적으로 초음파상 경계가 비교적 뚜렷한 고형종괴로 보이며 내부의 에코는 비특이적이며 CT 소견상 근섬유의 주행방향을 따라 길쭉한 모양을 보이고 조영제 주입전에는 주변 근육과 비슷한 등음영 또는 약간 저음영을 보이고 조영후에는 시간이 감에 따라 점차 조영증강되는 소견을 보인다. 저자들은 급속조영 CT를 시행하여 시간에 따른 조영 양상을 관찰함으로써 종괴의 조직학적 구성을 짐작할 수 있었고 병리조직학적으로 확진된 데스모이드 종양 2례를 경험하였기에 보고하는 바이다.
