Purpose: To present our experience with soft tissue reconstruction using anterolateral thigh free flap after resection of soft tissue sarcoma. Materials and Methods: Between January of 2003 and June of 2007, we treated 7 patients with soft tissue reconstruction using anterolateral thigh free flap after wide resection for soft tissue sarcoma. We retrospectively analyzed type and size of tumors, resection margin, size of defect after resection, time of operation, flap survival and complication. Results: The type of sarcoma was 3 synovial sarcoma, 2 malignant fibrous histiocytoma, 1 leimyosarcoma and 1 fibrosarcoma. The size of tumor varied from $3{\times}5\;cm$ to $7{\times}8\;cm$. The resection margins of tumors were negative in all cases. The size of soft tissue defect after resection varied from $6{\times}8\;cm$ to $15{\times}10\;cm$. The mean time of operation was 3.6 hours. All flaps were survived. Conclusion: Anterolateral thigh free flap appear to be ideal for reconstruction after wide resection of soft tissue sarcoma.

Purpose: This study was designed to provide the data base for the diagnosis and treatment of the foot tumor by investigation of the clinical and pathological characteristics and distribution of the foot tumor. Materials and Methods: 142 foot tumors of 141 patients were studied. All patients were diagnosed with surgical biopsy. We investigated clinical and pathological characteristics and epidemiologic distribution of the foot tumor by reviewing the medical records and imaging materials. The location of the tumors were classified with zone of Kirby et al. Results: 75 patients were female and 66 were male. The average age of the patients was 33.2 years old. Benign soft tissue tumors were the most as 68 cases, and followed by 57 benign bone tumors, 12 malignant soft tissue tumors and 5 malignant bone tumors. Ganglia were the most in benign soft tissue tumors as 36 cases, subungual exostoses in benign bone tumors as 18, squamous cell carcinomas in malignant soft tissue tumors as 7, and metastatic lung cancers in malignant bone tumors as 2. The rate of pain complaints was the highest in malignant bone tumors, the duration of symptom was longest in benign soft tissue tumors, and the size of the tumor was the biggest in malignant bone tumors. Neurological symptoms were found in only 3 benign soft tissue tumors. For the zonal distribution, zone 5 was the most in 59 cases and zone 4 was the least as 10. The most numbers of the benign bone tumors located in zone 5, of benign soft tissue tumors in zone 1, of malignant bone tumors in zone 1 and 2, and of malignant soft tissue tumors in zone 5. The methods of surgical treatment included intralesional or marginal resection, curettage with or without bone graft, toe amputation, below knee amputation and limb salvage. Conclusion: The tumors of the foot were rare and various, and mostly benign (88%), but we can do proper treatment of those tumors without excluding malignant tumors by considering the age of patients, pain, duration of symptom, size of the tumors, and zonal distribution.

A giant cell tumor of bone is a benign bone tumor, but has very high local recurrence rate and, very rarely metastasizes to the lung or a distant area. We report a case of a 29-year-old male patient presenting with a metastatic giant cell tumor of the soft tissue of the chest wall, who underwent a total resection of the radius for recurrence of the giant cell tumor. The tumor was not related to any bony structure of the thorax. We resected the tumor with a wide surgical margin. No evidence of malignancy was seen in the frozen and permanent pathological report.

Soft tissue masses of the extremities and torso are a common problem encountered by orthopaedic surgeons. Although these soft tissue masses are often benign, orthopaedic surgeons need to recognize the key features differentiating benign and malignant masses. An understanding of the epidemiology and clinical presentation of soft tissue masses is needed to develop a practical approach for evaluation and surgical management. Size and depth are the two most important factors on which triage decisions should be based. In a differential diagnosis of a tumor, it is important to know the characteristics of the soft tissue mass through detailed history taking and physical examinations before the diagnostic procedures. A variety of imaging studies, such as simple radiography, ultrasound, magnetic resonance imaging, positron emission tomography, computed tomography, bone scan, and angiography can be used to diagnose tumors. Know the ledge of advantages and disadvantages of each imaging study is essential for confirming the characteristics of the tumor that can be observed in the image. In particular, ultrasonography is convenient because it can be performed easily in an outpatient clinic and its cost is lower than other image studies. On the other hand, the accuracy of the test is affected by the skill of the examiner. A biopsy should be performed to confirm the tumor and be performed after all imaging studies have been done but before the final treatment of soft tissue tumors. When a biopsy is to be performed, careful attention to detail with respect to multidisciplinary coordination beforehand, cautious execution of the procedure to minimize complications, and expedient follow-up and referral to a musculoskeletal oncologist when appropriate, are essential.

Objective: The aims of this article are to differentiate soft tissue masses showing low signal intensity on T2-weighted images (T2WIs) according to the histopathologic findings. Conclusion: To know relatively small numbered soft tissue masses with low signal intensities on T2WIs adding characteristic location, morphology, signal intensities on other sequences might be helpful for differential diagnosis of mostly non-specific soft tissue tumors on MRI.

In spite of many advantages of the ultrasonography (USG), sometimes its features such as echotexture and homogenecity do not reliably distinguish between malignant tumors and benign ones, so caution is needed in making a diagnosis of solid masses of the soft tissue with USG.

Radiography of nasopharynx are routinely performed for nasopharyngeal soft tissue changes. Although CT scan is widely performed nowadays, the value of lateral neck radiograph is still important to detect the masses in the nasopharynx. The purpose of this study was to establish the constitution of the normal dimension of the nasopharyngeal soft tissue on the lateral neck radiograph and make a parameter of the nasopharyngeal soft tissue hypertrophy. We have made various measurements of the thickness of the nasopharyngeal soft tissue on the lateral skull films in 214 Korean adults (109 males and 104 females). We found that the diameter of the nasopharyngeal soft tissue was decreased by age and the value of males were always greater than that of females and the thickness of the roof was always less than the posterior wall.

Low-grade fibromyxoid sarcoma (LGFMS) is very rarely seen, and it commonly arises from the deep soft tissues of the lower extremities. Histologically, it is characterized by the presence of bland spindle cells with mainly storiform pattern of growth, set in alternating areas with a myxoid or fibrous stroma. The immunohistochemical reaction of this tumor permits a positive diagnosis of low grade fibromyxoid sarcoma and allows its distinction from a number of other benign and malignant soft tissue tumor. We report this rare case together with the review of the literature.

An extraskeletal osteosarcoma is a rare malignancy. A small number of cases and studies have been reported in the world and only two cases have been reported in Korea. We experienced an extraskeletal osteosarcoma around the knee joint of 91-year-old male who was the oldest case in the literatures. It was developed without history of trauma, irradiation, myositis ossificans, and heterotopic ossification of dermatomyositis. This patient was treated with excision alone, however he was alive and there were no sign of local recurrence or distant metastasis and functional loss during 1-year follow-up.

Malignant rhabdoid tumor is a highly aggressive tumor of children, that often arises in the kidney. Some rhabdoid tumors have been reported in various extra-renal location including the central nervous system, liver, skin, and soft tissues. In case of arising in soft tissues, it may be misdiagnosed as rhabdomyosarcoma. It is important to distinguish malignant rabdoid tumor from rhadomyosarcoma, because malignant rhabdoid tumor has more aggressive behavior and poorer survival rate. And this differential diagnosis can be performed by several immunohistochemistry. Here we report a case of malignant rhabdoid tumor that arose in lower abdominal wall with related articles.
