A choristoma is a tumor like mass of normal tissue in an abnormal location. Lingual osseous choristoma, previously known as osteoma of the tongue base, is rare entity. That is defined as a normal bone mass occuring in the soft tissue of either the skin or the mucosa of oral cavity. The cause of osseous choristoma of the tongue is still unknown, but only several theories have been suggested. Because of the rarity of this entity, our purpose is to add our case to the literature, and to discuss the nature of the disease.

A case of liposarcoma was reported in 52 year-old female. She had the operation history due to mediastinal lipoma at other Hospital before 26 months ago. Chest X-ray revealed a huge soft tissue mass- density at the entire right lung field, and left middle and lower lung field at admission. At the lateral film, the mass was located in the anterior and middle mediastinum. Transsternal bilateral thoracotomy was performed, followed by extirpation of liposarcoma, wedge resection of superior vena cava, angioplasty of superior vena cava, and then partial pericardiectomy. The post-operative treatment was 5500 rad irradiation. Post-operative course was uneventful, that was noticed by OPD follow-up for 10 months. Primary liposarcoma of the mediastinum is very rare tumor. This tumor grows to an enormous size, and symptoms are referable to compression of the contiguous intrathoracic structures. The treatment of choice is surgery in all cases. Such an approach serves to establish a tissue diagnosis, to relieve the patients* symptoms, and may results in a cure sometimes. Radiotherapy or/and chemotherapy seems to be ineffective, but should be further studied.

Actinomycosis involving the female genital tract has increased since the advent of the intra-uterine contraceptive devices (IUD) : the incidence of actinomyces in IUD users with pelvic inflammatory disease (PID) was reported to be between 17% and 30%. However a definte relationship between actinomyces and PID has not been demonstrated as yet. We present a case of pelvic actinomycotic infection that was initially diagnosed by means of fine needle aspiration. A 57-year-old female presented with urinary frequency and difficulty for 100 days. Computerized tomographic findings showed a mixed heterogenous soft tissue mass in the left superior aspect of urinary bladder. Fine needle aspiration was done under the impression of urinary bladder cancer. Microscopically, smears disclosed many sulfur granules in necrotic background with many neutrophils, histiocytes, multinucleated giant cells and granulation tissue. These findings were confirmed by surgical removal of the mass.

A 44-year-old man was transferred to our department for mediastinal mass. He had suffered from only an easily fatiguable condition for 1 month. A physical examination and laboratory finding of the patient disclosed no abnormality. A chest radiograph showed a soft tissue tumor in the posterior mediastinum. It was well circumscribed and ovoid. Invasions to adjacent organs were not seen. Therefore it was though the 5th intercostal space. The tumor mass was attached to the visceral pleura of the right upper lobe by a pedicle and this pedunculated tumor laid entirely within the pleural cavity. Excision of the tumor which measured 7$\times$7$\times$3cm was done easily. Pathologic studies confirmed the diagnosis of localized fibrous tumor of the pleura. Localized fibrous tumor of the pleura is rare, This tumor along ith the evidence from ultrastructural and immunohistochemical studies has led most researchers to conclude that localized fibrous tumor is not of the mesothelial origin but arises in the submesothelial connective tissue.

Primary neoplasms of the ribs and sternum are rare. Most primary bony chest wall neoplasms are malignant, and chondrosarcoma is the most common malignancy in this location The etiology of chondrosarcoma is unknown. Definitive diagnosis of chondrosarcoma can only be made pathologically. The natural history of chest wall chondrosarcoma is one of slow growth and local recurrence. Most tumors of the sternum require wide resection and reconstruction procedures, with potentially serious postoperative problems. Advances in chest wall reconstruction primarily through refinement in muscle transposition and clarification of the functional anatomy and blood supply of trunk muscles, has resulted in a more aggressive resection of the these tumors . Recently we experienced a case with chondrosarcoma of the sternum. A 56 year-old man was admitted to our hospital due to painless, slowly enlarging mass at the left sternoclavicular junctional area. The chest radiograph strongly suggested an underlying cartilaginous neoplasm owing to the appearance of typical flocculent and curvilinear calcifications within the lesion. On CT of the chest, the tumor exhibited a scalloped or lobulated contour, hypodensity of the nonmineralized component in comparison to adjacent muscle, and characteristic stippled cartilaginous matrix mineralization, also typical for cartilaginous neoplasm. The patient underwent wide resection of the chest wall tumor include with a 2-3cm margin of normal tissue on all sides and the thoracic skeletal defect was reconstructed with polytetrafluoroethylene [Gore-Tex] soft-tissue patch. Soft tissue reconstructive procedure was done with the pectoralis major muscle transposition. The patient had an uneventful postoperative course and discharged without adjuvant treatment such as radiation and chemotherapy.

Depression of facial contour after parotidectomy is still challenging to many of surgeons. A 68-year-old man presented with a 4-month history of a painless swelling in both parotid area. The mass was multiple and fixed at the parotid region. We conducted a parotid duct preserving bilateral superficial parotidectomy by one-stage operation to remove the multiple tumors. A lazy S incision was made in both preauricular area and the peripheral branches of the facial nerve were identified using surgical landmark. After dissecting the branches of the facial nerve and parotid duct, main parotid duct was preserved but only small fine ductules from the superficial lobe were ligated. Parotid gland was excised from its anterior aspect with about 1 cm of normal parotid tissue margin. The patient was followed up for 6 years to evaluate postoperative parotid gland function and the computed tomography (CT) was taken. Patient was satisfied with no significant complication such as sunken changes in facial contour, facial nerve function. As far as we know, it is the first study to compare long-term soft tissue contours of soft tissue of duct preserving superficial parotidectomy with duct sacrificing superficial parotidectomy by means of CT findings.

Giant cell tumor of the tendon sheath (GCTTS) is a slowly growing, benign soft tissue tumor. The tumors occur predominantly on the hands and feet. Although the clinical and histopathologic features are well-defined, only a few reports have described the cytologic appearance of this entity. A 26-year-old woman presented with a gradually developing circumscribed soft tissue mass near the proximal phalanx of her left little finger for one year. Imprint and fine needle aspiration (FNA) smears were obtained from the excisional biopsy specimen. The imprint smears were composed of predominantly singly dispersed bland mononuclear cells and several giant cells. The mononuclear cells were polygonal to round, and they showed a histiocyte-like appearance. Osteoclast-type multinucleated giant cells of various sizes were randomly scattered throughout the smears, and these cells contained 3 to 50 nuclei. Nuclear atypia and pleomorphism were absent in both the single and giant cells. Loose aggregates of hemosiderin-laden macrophages and binuclear stromal cells were also seen. The cytologic features of the FNA smears were similar with those of the imprint, Additionally, the FNA smears contained several clumps of densely collagenous stromal tissue that were seldom noted in previously reported cytologic material. The cytologic features were well-correlated with the concurrent histologic findings and the diagnosis of GCTTS was made. When the clinical and radiologic datas are integrated, the diagnosis of GCTTS can be strongly suggested, based on the pre-operative cytologic specimen.
