Solitary fibrous tumor (SFT) is an uncommon spindle cell neoplasm that is usually presented as a pleural origin localized tumor. There are few cases, found in thyroid. Twenty six cases found in thyroid have been reported since 1993, and two of these were malignant. We report another malignant case in this study; a 55 years old man visited out-patient clinic due to palpable mass of anterior neck, and pathologically diagnosed as malignant SFT of thyroid after surgical resection. In this study, we focus on the clinical features of this uncommon disease along with other literature reviews.

Solitary fibrous tumor (SFT) is a rare neoplasm, which is usually presented as a pleural based mass, but can also occur in unusual locations based on its mesenchymal origin. However, the radiologic features of SFT occurred in the ischiorectal fossa have been rarely reported. In this case, we describe the MRI findings in a case of a SFT involving the ischiorectal fossa of a 36-year-old man. The tumor appeared as homogeneous iso-signal intensity relative to the adjacent muscle on T1 weighted images, a mixed high signal intensity on the T2 weighted images, and heterogeneous enhancement following the administration of the contrast material.

The fat-forming variant of solitary fibrous tumors (SFTs) is a rare soft tissue neoplasm that was previously referred to as a lipomatous hemangiopericytoma (L-HPC). The most common affected site is deep soft tissue. Here, we present the first case, worldwide, of a fat-forming variant of SFT of the pleura. A 74-year-old man presented with left lower chest pain. Chest radiographs showed a mass-like lesion at the left lower lung field and chest computed tomography revealed a 12 cm fat-containing enhancing mass that was well-separated, lobulated and inhomogeneous. Radiology findings suggested a liposarcoma. Percutaneous needle biopsy was performed and pathological diagnosis of the mass was a fat-forming variant of SFT. Surgical resection was carried out and there has been no recurrence to date. So, a benign fat-forming variant of SFT must be considered as one of the differential diagnoses of lipomatous tumors of the pleura.

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.

Ossifying fibroma is a slow-growing benign neoplasm that occurs most often in the jaws, especially the mandible. The tumor is composed of bone that develops within fibrous connective tissue. Some ossifying fibromas consist of cementum-like calcifications, while others contain only bony material; however, a mixture of these calcification types is commonly seen in a single lesion. Of the craniofacial bones, the mandible is the most commonly involved site, with the lesion typically inferior to the premolars and molars. Ossifying fibroma of the jaw shows a female predominance. Some reports of ossifying fibroma have been published in the literature; however, this report continues the research on this topic by detailing 3 types of ossifying fibroma findings on panoramic radiographs and cone-beam computed tomographic images of 4 patients. The radiographs of the presented cases could help clinicians understand the variations in the radiographic appearance of this lesion.

Actinomycosis is a chronic suppurative granulomatous disease due to Actinomyces israelii characterized by multiple abscess and sinus tract formation with dense fibrous scarring. This disease, especially thoracic infection, is very rare in Korea so we are not famiIliar with to make diagnosis and treatment. Otherwise the unspecificity of the clinical symptoms and the lack of adequate examination recedure (as anaerobic fungus culture) are the causes of misdiagnosis. Thoracic actinomycosis is very similar to chronic infectious disease of the lung and chest or thoracic neoplasm. Recently we experienced a case of thoracic actinomycosis (bronchopulmonary) which had been confused with chronic lung abscess and pathologically confirmed as broncho-pulmonary actinomycosis. The purpose of this report is to review our experience more thorouly to enhance consideration of Artinomycosis.

Lipoma is the most common benign neoplasm of the body with rare occurrence in the oral cavity. It represents 1~4% of benign neoplasms of the mouth, which affect the buccal mucosa, floor of the mouth, tongue and lips. We report a case of lipoma in the labial vestibule with extraoral swelling, which could easily be misdiagnosed as an odontogenic abscess. Excisional biopsy in this case revealed well-circumscribed masses, surrounded by a thin fibrous capsule and composed of sheets of mature adipocytes, arranged in a "chicken wire" configuration. After a computed tomography scan, excisoinal biopsy was done, and there were no recurrence after 5-month follow-up period.

Atypical fibroxanthoma(AFX) is a tumor that occurs as a solitary and ulcerative nodule on actinically damaged or radiation damaged skin of the head and neck in the elderly. AFX is a pleomorphic spindle cell neoplasm of the dermis, which is a clinically benign reactive lesion despite of apparently malignant histologic features. We report a case of AFX which developed on the nasal root area of a 23-year-old man. This case is very unusual in terms of site(less sun-damaged area), overlying skin feature(grossly normal skin) and age(too young). This tumor was completely removed with surgical excision and remained free of recurrence for a period of about 1 year follow-up.

Elastofibroma, dorsi, a rare, noncapsulated benign entity is characterized by the proliferation of fibrous tissue with elastin and occurs most often in the infrascapular area of elderly women. It is a relatively slowly growing lesion and no reports of malignant transformation exist. Which is overlooked easily because it rarely causes symptoms such as tenderness, pain, or restriction of movement. The diagnosis of elastofibroma is established by typical histopathologic findings. Radiographic evaluation may lead to a presumptive diagnosis. We experienced a case of elastofibroma dorsi in a 48-year-old woman and report this case with a review of the literature.

This case was diagnosed as multiple cementoosseous dysplasia on the basis of clinical & radiological features but was diagnosed as ossifying fibroma on the basis of histopathological feature. The histopathologic features of the multiple cementoosseous dysplasia and cementoossifying fibroma have common features of cementum, fibrous network and bone. Multiple cementoosseous dysplasia is reactive lesion and shows restricted lesion size, occurred on anterior and posterior tooth of the mandible and needs no treatement except periodic follow up. But Cementoossifying fibroma is the true neoplasm and grows continuously and needs surgical removal. The final diagnosis of the multiple cementoosseous dysplasia requires good correlation of the clinical, histopathological, and radiological features.
