Pleomorphic hyalinizing angiectatic tumor (PHAT) is a rare, low grade neoplasm which usually occurs in subcutaneous soft tissue. Histologically, it features ectatic blood filled vessels surrounded by hyalinized stroma and pleomorphic spindle cells. Clinically and histologically, PHAT could be misdiagnosed as such tumor as neurogenic tumor, malignant fibrous histiocytoma. About 100 cases of PHAT have been reported so far, and it is even rarer in head and neck area. We experienced a case of PHAT in 41-year-old male with several months of history of gradually enlarging neck mass which was surgically removed by wide excision.

From May 1965 to December 1990, 78 patients with chest wall tumors were operated on. The mean age of the patients was 31.5 years with 50 male and 28 female patients. Forty-nine cases[62.8%] were developed at bony or cartilaginous wall and 29 cases[37.2%] at soft tissue of chest wall. Thirty-two of them[41.0%] were malignant, either primary or metastatic, and 46 tumors[59.0%] were histologically benign. For 55 patients who were operated on since 1982, 6 surgical biopsies. 39 tumor excisions, and 11 wide excisions with chest wall reconstruction were done. Preoperative factors favoring diagnosis of malignant neoplasm were; 1] old-aged male patient, 2] bone or cartilaginous tumors, 3] involvement of multiple ribs, 4] complaint of pain, 5] large size on palpation[larger than 4cm]. With proper diagnosis and management plan, we think, operations of chest wall tumors can give good results.

AVMs is not a neoplasm, but a congenital developmental anomalies.$^{5)}$ In oral and maxillofacial area, the high recurrence rate and more facial disfigurement give a difficult problem to surgen and patient.$^{8)}$ Conventional treatment modality nowadays is presurgical embolization and surgical resection. In treatment planning, we consider the possibility of complete surgical resection and the esthetics of soft tissue reconstruction. But, two things are very difficult to achieve. We present a patient with AVMs in left upper lip, he had presurgical embolization with Ivalon and Bucrylate, and conservative surgical procedure. So we present this possible treatment modality.

Parachordoma is a very rare, slow-growing, and low-grade malignant tumor that occurs in the extremities and trunk. The differential diagnosis includes extraskeletal myxoid chondrosarcoma and chordoma in the histologic finding. Thus, histologic findings with immunohistochemistry may be helpful in distinguishing parachordoma from extraskeletal myxoid chondrosarcoma and chordoma. I report with a brief review of literatures one case of parachordoma of the chest wall which was successfully treated by en-bloc resection and chest wall reconstruction using 2 mm Gore-Tex$^{\circledR}$ soft tissue patch and free from recurrence for 16 months.

Lipoma is a benign tumor composed of mature adipocytes and the most common soft tissue mesenchymal neoplasm but relatively rare in the oral cavity. Lipoma of the tongue is uncommon and especially multiple lipomas are quite rare and only several cases of those were reported. We describe an unusual case of multiple lipomas of the tongue.

Huge chondrosarcoma is a rare form of primary malignant tumor of the chest wall. We operated on a 60 year old female patient who had a huge anterior chest wall mass with local invasion into the pericardium and satellite tumors on the visceral pericardium of the heart. En-bloc resection of the huge tumor including both upper 3 ribs, both clavicles, manubrium of the sternum, pleura, and pericarium, was followed by complex chest wall reconstruction using a Gore-tex soft tissue patch and latissimus dorsi musculocutaneous free flap.

We report a case of a 13-year-old girl who presented with a 2-month history of intermittent abdominal pain. Laboratory examination showed hepatitis and pancreatitis. Because of persistent vomiting, computed tomography (CT) was performed, which revealed a circumferential soft tissue density in the duodenal wall, causing partial obstruction. Supportive therapy failed. Repeat CT showed no significant change from the initial study. The patient underwent upper endoscopy, which revealed a mass in the second portion of the duodenum, which occluded most parts of the lumen. The histopathological finding was consistent with an anaplastic large cell lymphoma, a rare form of small bowel neoplasm. After the third course of chemotherapy, complete resolution of the mass was noted, and her symptoms were relieved.

Extraskeletal osteosarcoma (ESOS) is a malignant soft tissue neoplasm producing osteoid, without any continuity with the bone or periosteum. Primary ESOS presenting in the mediastinum is an extremely rare, yet aggressive malignant tumor associated with a poor prognosis. We report a case of primary ESOS arising from the thymus in a 63-year-old male patient.

Malignant peripheral nerve sheath tumor (MPNST) is rare, accounting for 5-10% of all soft tissue sarcomas. MPNST is characteristically aggressive and has a poor prognosis. Fifty percent of patients with MPNST have neurofibromatosis type 1 (NF1). NF-associated MPNST occurs more often at younger ages than sporadic MPNST, but the survival difference is controversial. Superficial MPNST from a recurrent neurofibroma is extremely rare and only a limited number of cases have been reported in the literature. Herein, we report an unusual case of superficial MPNST from a recurrent neurofibroma in a patient without NF1.

Solitary plasmacytoma (SP) is an uncommon form of plasma cell neoplasm occurring intraosseously or in soft tissue and presents as a single mass of monoclonal plasma cells. SP in the maxillary sinus is rare and can be misdiagnosed as other maxillary sinus tumors. The essential examinations in patients with the initial diagnosis of plasmacytoma are bone marrow biopsy, serum and urine electrophoresis, and kappa/lambda ratio (κ:λ ratio) to rule out multiple myeloma (MM). Herein, a rare case of SP in the maxillary sinus treated by surgery and localized radiation is reported. At the 10-year follow-up examination, local recurrence or disseminated development of MM were not evident.
