Purpose: Malignant fibrous histiocytoma(MFH) is the most common soft tissue sarcoma in adult. As to this date, tissue development, treatment and prognosis of the tumor has not been definitely clarified, however, it has been reported that wide surgical resection of the tumor along with the radiotheraphy and chemotheraphy is needed for treatment. In MFH with high recurrence rate, the reconstruction method and points to be considered for reconstruction in recurrent case were studied in 10 patients who were treated in our hospital. Methods: From August of 1991 to August 2007, location of tumor, initial mass size, 1st recurred period, lymph node metastasis, recurrence rate, treatment modality, complication, reconstruction in recurrent defect, and follow up period was studied in 10 patients who underwent reconstruction at our Plastic surgery department following wide excision. Results: The average age was 62.8(46 - 73) years old, average follow up period was 7.7(1 - 17) years. Various reconstructions has been performed for recurrent cases and postoperative chemotheraphy and radiotheraphy was done. As for reconstruction in recurrent cases, After wide excision, local flap was performed in 6 cases, and free flap in 2 cases. After radiotherapy, osteoradionecrosis was occurred in 4 cases. Recurrence rate was 1 - 5(2.6) times and reconstruction due to recurrence was 7 out of 10 cases(70%). Conclusion: The treatment modality of MFH is not yet defined. Due to it's high recurrence rate, radiotherapy and chemotherapy is commonly combined with surgery. Even still, additional excision and reconstruction may be required. Therefore, possibility of re-operation must be considered when performing every excision and reconstruction; in case a recurrence or osteoradionecrosis occurs. Free flap coverage should be left as the last resort, according to the principle of reconstruction. Nevertheless, if the defect is large or osteoradionecrosis is present, it will benefit greatly to the patient's quality of life.

Malignant fibrous histiocytoma(MFH) is a deep-seated pleomorphic sarcoma, which occurs principally as a mass of the extremities, abdominal cavity, or retroperitoneum in adults. However, it only rarely occurs in the chest wall. An 85-year-old man had undeergone excision of a small mass on the right posterior chest wall under local anesthesia 14 months age. However, the lesion did not heal and the mass recurred. He was referred to our hospital after the mass had grown to a size of 10.5$\times$8$\times$4cm with a 3$\times$3cm skin defect. Intraoperative frozen biopsy revealed MFH. An en-bloc wide resection and thin-thickness skin graft from his thigh were performed. Although distant metastasis to the lund developed 14 months later and the patient died 2 months later, there was no local recurrence. Thin-thickness skin graft is a simple method for a wide range skin defect, especially in the old age. He recovered in good condition without any physical disabilities.

Primary malignant fibrous histiocytoma (MFH) is a malignant tumor of mesenchymal origin that rarely occurs in the urinary tract, particularly in the urinary bladder. Unlike urothelial carcinoma, which accounts for most bladder cancers, it occurs in the submucosal portion of the bladder wall and consists of the lamina propria, muscularis propria, and adventitia. It is presumed to originate from poorly differentiated pluripotent mesenchymal cells in which fibroblasts and histiocytes are partially differentiated. Radiologically, it is known as the "non-papillary tumor" and is commonly diagnosed as a large mass without necrosis, which shows invasion beyond the muscularis propia. Although the prognosis of this rare malignancy depends on pathological parameters, it generally has a poor prognosis with high local tumor recurrence. Here, we present a case of primary MFH in the urinary bladder with clinical symptoms of lower abdominal pain without gross hematuria that recurred rapidly and showed an aggressive disease course.
