PURPOSE: Although liposarcoma is the second most common soft tissue sarcoma in adults, the incidence of liposarcoma of the head and neck is rare. There is only one reported case in Korea and moreover, only in adolescence. We report a case of liposarcoma on the neck in a 32-year-old male in adult. METHODS: The patient had a slow growing, none tender mass on the posterior neck without lymphadenopathy, which has been present for 3 years and recurred twice during that time. MRI showed a 1.5cm sized ovoid, well demarcated mass that was located in the subcutaneous layer of the posterior neck. RESULTS: The mass was surgically removed. The resection margin was free of tumor on frozen biopsy and histopathologic examination indicated myxoid and round cell liposarcoma. The whole body F-18 FDG PET-CT applied on the fourteenth day postoperatively, revealed a moderate FDG-uptaking soft tissue lesion showing postoperative wound healing process on the posterior neck region and there was no distant metastasis. CONCLUSION: Liposarcoma is the second most common soft tissue sarcoma in adults. But, it rarely involves the head and neck region. Prognosis is principally dependent on histologic subtype and grade. Low grade liposarcoma such as well differentiated and myxoid liposarcoma tend to recur locally, rarely metastasize. On the other hand, high grade liposarcoma such as round cell and pleomorphic liposarcoma have higher rates of local recurrence and distant metastasis. Complete surgical excision provides the most effective means of treatment. Radiotherapy or chemotherapy can be used as an asjunctive treatment modality.

Primary tumors of the spermatic cord are rare and basically of connective tissue origin. They are hardly ever considered in the differential diagnosis of intrascrotal swellings. Treatment consisted of radical orchiectomy without retroperitoneal lymph node dissection, and adjuvant radiation and chemotherapy. We report a case of liposarcoma of the spermatic cord in 54-year-old male. He has survived l5 months without evidence of recurrence.

Seventy four patients with soft tissue sarcomas treated by postoperative radiotherapy in the Department of Therapeutic Radiology, Seoul National University Hospital between August 1979 and September 1990 were analyzed. The follow-up period ranged from 3 to 145 months with a median of 51 months. Liposarcoma and malignant fibrous histiocytoma(MFH) constituted 54% of the cases and the histologic grades of tumors are as follows: grad I, 23 case; grade II, 17 cases; grad III, 24 cases; unknown grade , 10 cases. The patients were treated by marginal(17 cases), wide(55 cases) or compartmental(2 cases) excision followed by postoperative radiotherapy. The total radiation doses were 4200-8820 cGy(median 6000cGy), 180-200n cGy daily, 5 times per week. Of 74 patients, 35 utimately failed. The local control was 62.2% at 5 years and cumulative rik of distant metastasis was 22.3% at 5 years. The overall survival and disease free survival were 72.3% and 53.3% at 5 years, respectively. Survival after appearance of metastasis was 15.1% at 3 yeaers. Patients with liposarcoma experienced better local control that those with other histologic type and tumor grade and surgical resection margin significantly correlated with local recurrence, distant metastasis and overall survival on univeriate analysis. In conclusion, re-excision is needed for patients with positive surgical resection margin to improve local control and further therapeutic measures using effective chemotherapy should be explored in the hope of improving overall survival.

We report on a first case of bone marrow metastasis by dedifferentiated liposarcoma. A 39-year-old male diagnosed with retroperitoneal dedifferentiated liposarcoma underwent surgery and postoperative radiotherapy. In spite of radiotherapy, his whole-body positron emission tomography showed high uptake in multiple bone metastasis. With thrombocytopenia, bone scan suggested bone marrow involvement. After bone marrow biopsy, bone marrow metastasis by dedifferentiated liposarcoma was finally confirmed. He was administered with systemic chemotherapy with doxorubicin. But he died 3 months after chemotherapy due to disease progression. This case revealed that in a patient of unexplained cytopenia with dedifferentiated liposarcoma, bone marrow metastasis should be in consideration.

The soft tissue sarcoma ih the Orthopedic surgery is not common, occuring in less than one percent of all malignant tumors. Whille the sarcoma is comparatively highly malignant, its treatment has been varied, and the effect of the each treatment has been controversial and generally poor on statisties. We studied 58 cases of soft tissue sarcoma in the Orthopedic department of Pusan Gospei Hospital in the 6 years period from March, 1975 to March, 1981. We confirmed the sarcoma diagnosis by biopsy, and measured the size, the degree of local infilteration and occurrence of metastasis with the help of plain X-ray, angiography, lung and bone scan, and computerized tomograms. We made treatment plans according to above results. We classified the soft tissue sarcoma into 8 histologic types and obtained following conclusions: l. Among the 58 cases of soft tissue sarcoma, and majority is consisted of fibrosarcoma, liposarcoma and rhabdomyosarcoma. 2. There were 41 cases occurred in the lower extremity and 17 cases in the upper extremity. Thus soft tissue sarcoma are more frequent in the lower extremity, especially in thigh (2 patients). 3. We found 19 cases between the age of 41 to 50 years. In general, the soft tissue sarcoma are more frequent between the age of 31 to 50 years. 4. Among the 58 cases, 10 patient came to our hospital because of recurrence of soft tissue sarcoma, after receiving local excision in other hospitals. In other words 17 percent of our cases showed recurred sarcoma and duration of recurrence was within 16 months. 5. Metastasis of the soft tissue sarcoma had taken place in 17 patients (29%), most frequently metastasis to the lung in 12 cases (70%). 6. We treated 30 cases by chemotherapy and radiotherapy after excision or amputation. In 15 sarcomas that could not be excised, but the medical treatment with chemotherapy and radiotherapy. 7. The follow-up study revealed better result obtained in the group of aggresive treatment with anticancer chemotherapy and radiotherapy after excision or amputation.

Azathioprine is frequently used for the treatment of inflammatory bowel diseases (IBD) such as Crohn's disease and ulcerative colitis. Lymphomas, squamous cell carcinomas, and undifferentiated pleomorphic sarcomas have been reported among patients receiving azathioprine therapy. Herein, we report a case of pleomorphic liposarcoma of chest wall which occurred in a 44-year-old man with Crohn's disease taking azathioprine. He was diagnosed with Crohn's disease 3 years ago after suffering from abdominal pain and hematochezia for 12 years. He had been taking 50 mg of azathioprine per day for 23 months when he visited the thoracic and cardiovascular surgery clinic due to right chest palpable mass that had rapidly grown during the past 2 months. Excisional biopsy was performed and the mass was diagnosed as pleomorphic liposarcoma. Therefore, he underwent radical excision of the right chest wall mass, which measured 11.0x6.5 cm in size. He is scheduled to receive radiation therapy and chemotherapy.

Pelvic sarcoma is rare disease. It is very difficult to detect and to treat such tumor in early stage due to the location. But modern anti-cancer therapeutic modalities improve the prognosis. Herein we analyze the experiences of 8 patients of pelvic sarcoma during a recent 10 year period. Six patients were male and 2 were female. Presentations were urinary obstruction in 3 patients, abdominal mass in 5. Various radiologic diagnostic examinations were performed and the results of compressing the adjacent organs rather invasion were founded. Distant metastasis was not recognized in all cases. Exploratory laparotomies were performed in all patients. In 5 patients, mass excision with or without adjacent organs was possible and fecal or urinary diversions were done. In 3 patients, the excision was impossible and fecal, urinary diversions and biopsy for pathologic diagnosis were done. Rhabdomyosarcoma was in one patient, leiomyosarcoma in 3, liposarcoma in 3 and extraskeletal myxoid chondrosarcoma is one. In postoperative long term follow up, the 3 patients died within 6 months whose tumors were not resectable. The 3 patients survived more than 3 years whose tumor masses were excised and who received adjuvant chemotherapy and/or radiotherapy. In one patient, a local recurrence occurred and died of sepsis during postoprative chemotherapy, in one patient now in observation under radiotherapy. The treatment of sarcoma in pelvic cavity must include multiple anti-cancer therapeutic modalities.

Vascular catheters are associated with complications such as infection, thrombosis and stenosis. The embolization of a venous catheter fragment is a rare complication. A 39-year-old woman underwent placement of a totally implantable venous access device for chemotherapy to treat a recurrent liposarcoma of the left thigh. The "pinch-off sign" was noted on a routine chest X-ray but that was ignored. Three-months after implantation of the intravenous access device, the indwelling central catheter was fractured and embolized to the pulmonary trunk. The catheter in the pulmonary trunk was successfully removed through a percutaneous femoral vein approach using a pigtail catheter and goose neck snare.

Sarcoma of prostate and bladder is rare malignant disease and its prognosis is very poor because of rapid growing tendency. Recently the combined treatment of surgery, radiotherapy and chemotherapy has increased the survival rate, significantly A clinical observation and retrospective analysis were made on 9 patients with primary sarcoma of bladder and prostate which were admitted during the period of 8 years and 8 months from January. 1971 to August, 1979. The results obtained were as follows: 1. The age distribution ranged from 2 years to 51 years and the prostate sarcoma was most common in the young age group upto 15 years. 2. The presenting symptoms were dysuria in 6 patients (67%), acute urinary retention in 4 patients(44%), hematuria in 3 patients(33%), frequency in 2 patients(22%), G-I symptoms were also noticed in 4 patients(44%). 3. The histologic types were 6 rhabdomyosarcoma. 1 leiomyosarcoma, 1 liposarcoma and 1 lymphoma. 4. Among 2 cases in which metastasis was confirmed, lung and liver were the sites of metastasis in a prostate rhabdomyosarcoma and the cervical lymph node in a bladder lymphoma. 5. Four patients of 9 prostate and bladder sarcomas were treated with surgery and/or chemotherapy and/or radiotheraphy. Of these, 1 patient is alive 4 months since surgery to date, 2 patients died within l year and 1 patients is presumed dead.
