Alveolar soft part sarcoma, named by Christopherson in 1952, is a very rare soft tissue sarcoma. It reportedly accounts for 0.5 to 1.0% of all soft tissue sarcoma and no established treatment principle assists it. The relative lack of symptoms makes it easily overlooked and consequently early diagnosis is frequently impossible. Often, the metastasis to the lung or the brain is the first manifestation of the disease. In some cases wide excision is not performed because it is misdiagnosed as a benign tumor. Authors experienced 7 cases of alveolar soft part sarcoma in 20 years and found the ultimate prognosis grave and the treatment not promising. Therefore, the authors recommend the following; 1. Early diagnosis and early treatment are important for successful management of alveolar soft part sarcoma. 2. Preoperative incisional biopsy is necessary for pathologic diagnosis. 3. The recommended treatment modality is a combination of wide excision, chemotherapy and radiotherapy.

Alveolar soft part sarcoma (ASPS) is a rare soft tissue sarcoma, which occurs predominantly in adolescents and young adults. The cytological characteristics of this condition have been described only rarely in the literature. Here, we report a case of alveolar soft part sarcoma. A 28-year-old man presented with a mass in his right buttock, which had persisted for three years. The mass was subjected to a fine needle aspiration cytology (FNAC). The smears were cellular. The observed tumor cells were round or polygonal, and exhibited vesicular nuclei with prominent nucleoli and finely granular cytoplasm. Naked nuclei were frequently detected. Tumor cells were arranged singularly, but occasionally in a pseudoalveolar pattern.

Alveolar soft part sarcoma is a rare soft tissue tumor. Few cases on fine needle aspiration cytology have been reported in the literature. We experienced a case of recurrent alveolar soft part sarcoma of the right thigh diagnosed by fine needle aspiration cytology in a 47-year-old man. Cytologic findings showed single cells and clusters associated with thin wailed vasculature in a distinct pseudo-alveolar pattern. The tumor cells exhibited round or ovoid abundant granular cytoplasm and large pleomorphic nuclei with prominent central nucleoli.

As we know, alveolar soft part sarcoma is usually found at the head region in children and thigh in adults. It is very rare tumor that has poor prognosis due to its late detection after distant metastasis in spite of its slow growth rate. It is histologically characterized by pseudoalveolar pattern tumor cells. And metastasis usually occur in the site of lung, brain and skeleton in order lately. We have managed two cases of the sarcoma, one which took place in relatively rare part, pelvic bone and has spread to the brain, the other which primarily occured in the calf. For its varity, we report these two cases with reviewing of the literatures.

Alveolar soft part sarcoma (ASPS) with skull and brain metastases is extremely rare. A 53-year-old patient diagnosed as skull metastasis of ASPS visited our clinic complaining of an outgrowing scalp mass in spite of radiation therapy. Past medical history revealed that the patient had been diagnosed and treated for ASPS of the thigh 4 years ago. Magnetic resonance imaging revealed a hyperintense ovoid mass on the T2-weighted image, an isointense on the T1-weighted image, and a homogeneous enhanced mass with gadolinium. Another small-sized enhanced mass with mild peritumoral swelling was found at the deep white matter of the left frontal lobe. A gross total resection of the skull lesion with cranioplasty was performed for the surgical defect. A histologic examination of the specimens revealed metastatic ASPS involving the skull. Surgery with a total removal of the lesions may be effective for improving a patient's symptoms especially from neurological dysfunction.

Alveolar soft part sarcoma(ASPS) is a rare malignant neoplasm with a distinct clinicopathologic entity of which fine needle aspiration(FNA) cytologic findings have been described in only a few reports. Although patients usually present with an isolated soft-tissue mass in the extremity, metastasis can occur in about 13 % of total cases and the most frequent metastatic site is the lung. We have recently experienced a FNA cytologic case of ASPS in the lung. A 23-year-old female patient was admitted to this hospital due to 2-month-history of cough She had been good in health before the visit. Chest computed tomography revealed multiple, variable sized, bilateral pulmonary nodules. Physical examination and other staging work up revealed no other lesions except for pulmonary nodules. A percutaneous transthoracic FNA was performed from the pulmonary nodules. The smear was cellular and most cells were arranged singly. In addition, a few clusters lined by thin-walled vasculature with a pseudoalveolar pattern were present. Some of the tumor cells were large and polygonal lo oval with abundant granular or vacuolated cytoplasm. Most cells were naked nuclei showing finely granular chromatin pattern with prominent central nucleoli.

Alveolar Soft Part Sarcoma(ASPS) is a rare entity that invariably ends in death from the disseminated disease. Although the most common site of metastasis is the lung, the central nervous system is also the third common site. Its histogenesis remains to be unknown and the gold standard treatment is radically surgical removal of the mass. However, adjuvant chemotherapy and radiotherapy are known to be less effective. The authors present a 24-year-old man who was admitted with headache and neck discomfort. Magnetic resonance( MR) imaging scans demonstrated multiple masses in the left frontal lobe, parietal lobe, and right cerebellum. The patient underwent surgery to remove multiple masses in the staged fashion. The postoperative course was uneventful, but the patient committed suicide 5 months later. The authors reviewed the pertinent literature and discussed this clinical entity with references.

Alveolar soft-part sarcoma(ASPS) is a rare, aggressive malignancy of uncertain histologic origin with a propensity for vascular invasion and distant metastasis. ASPS may mimic benign vascular neoplams of malformation but careful evaluation of the unique imaging features on CT scans, MR images, and angiograms lead to the correct diagnosis. ASPS of the tongue is slow-growing, painless mass, especially ASPS of the base the tongue is difficult to be noticed by patient, dentists or oral and maxillofacial surgeons on oral examintion because of its location and clinical resemblance to a benign lesion. And it leads to delayed or inadequate diagnosis. We report radiologic and clinical features of an ASPS of the basal portion of the tongue in a 17-year-old boy, showing normal appearance, but palpation of the tongue and floor of the mouth reveals the tumor. Among the 23 cases of a primary ASPS of tongue reported, 7 cases occured on the basal region of the tongue, inculding the present one. There has been no recurrence or metastasis as of 3 years postoperatively.

Purpose: Evaluation of results of free flap as a method of reconstruction in soft tissue defect after wide excision of soft tissue tumor of extremity. Materials and Methods: From 2000 through 2007, 11 patients received free flap surgery for soft tissue defect after wide excision operation for soft tissue tumor of limbs. Four cases were upper extremities and seven were lower extremities. Four subjects were diagnosed as squamous cell carcinoma, three as malignant melanoma, two as synovial sarcoma and one as malignant fibrous histiocytoma and alveolar soft part sarcoma. Donor sites of free flap varied with anterolateral thigh flaps in six cases, latissimus dorsi flaps in four, reverse forearm flap in one. By the method of doppler ultrasound, venous circulation was evaluated for the survival of each flap on the third, fifth and seventh day respectively after the operation. Results: 10 of 11 free flaps were successfully survived. Necrosis of free flaps in 1 cases occurred in case of anterolateral thigh flap. Conclusion: Free flap can be a useful method for reconstruction of soft tissue defect after wide excision of soft tissue sarcoma of extremity.

Malignant fibrous histiocytoma(MFH) is the malignant part of mesenchymal cell-originated tumor, which is supposed that the tumor is presented various histologic features consisted of fibrosarcomatic and histiocytic portions. When the tumor is arisen in the head and neck region, the most affected sites are the nasal cavity and paranasal sinuses, and secondly the maxillary alveolar bone is occasionally influenced. Therefore, MFH can readily involve the adjacent alveolar bone. The treatment of MFH in the head and neck is various, that is, the involved sites and the differentiation of tumor must be considered when the tumor is treated. The treatment protocols are subjected to general ones of soft tissue sarcoma, and simple or combination therapy is used in the surgery, chemotherapy and radiation therapy. So, we report a clinical case of chemotherapy involving intraarterial chemotherapy, and surgery of malignant fibrous histiocytoma(MFH) in the maxilla, with review of the literature.
