Free grafting of oral mucosa for minor oral reconstruction was first described by Propper in ridge extension surgery. Situation calling for mucosal grafting procedures may relate to periodontal surgery, minor and major preprosthetic surgery, implant surgery, reconstruction in deformity cases after trauma, congenital cleft, gross atrophy and ablative tumor surgery. In the cases of 9 patients with mucosal defect of intraoral or orbital cavity after wide excision of tumor, preprosthetic surgery, and orbitoplasty, full-thickness mucosal graft were used to close a large defect. Four patients received buccal mucosal graft for preprosthetic surgery or orbitoplasty, one patient had benign tumor and the others had malignant tumors located on the palate or upper alveolus. Buccal mucosal graft donor site morbidity and trismus were minimal and healing of surgical defect was satisfactory. So we present the case with review of literatures.

Tuberous sclerosis is an autosomal dominant disorder characterized by mental retardation, epilepsy, and adenoma sebaceum. Associated lesions include retinal phacomata, shagreen patches, subungal fibromata, and benign visceral tumors such as pulmonary lymphangioleiomyomatosis. Lymphangioleiomyomatosis occurs exclusively in women, usually during the child-bearing years, and is characterized by proliferation of smooth muscle along the lymphatic vessels of the lung, thorax, abdomen. Proliferation of smooth muscle results in interstitial and obstructive lung disease, recurrent pneumothorax, and chylous pleural effusions. We saw two cases of pulmonary lymphangioleiomyomatosis associated with tuberous sclerosis in women of reproductive age. We report the cases with a brief review of the literatures.

Granular cell tumor(GCT) of tracheobronchial tree is a rare neoplasm comprising approximately 6-10% of all GCT and about 1.6% of all benign tumors of the tracheobronchial tree. Since the first observation of GCT in the bronchus by Kramer in the late 1930s, less than 100 cases have been reported in tracheobronchial tree, and probably no such case have been published in Korea yet. Here we report an experience concerning 53 year-old women with an active pulmonary tuberculosis, who also was diagnosed to have a bronchial GCT on bronchoscopy and immunohistochemistry of the specimens.

Granular cell tumors are relatively uncommon benign laryngeal lesions thought to originate form Schwann cells. The granular cell tumor occurs everywhere in the body, especially in the head and neck. The larynx is relatively an uncommon location, accounting for approximately 3 to $10\%$ of all reported cases. Typically the most common presenting symptom is hoarseness, with some patients also presenting stridor, hemoptysis, dysphagia, and otlagia. But the tumor may be asymptomatic and discovered only incidentally during a routine examination. The diagnosis of granular cell honor can be confirmed by histopathologically and immunocytochemical staining fer S-100 antigen. Treatment of a granular cell tumor consists of a wide local excision by the endoscopic, transoral or laryngofissure methods. Recently, CO2 laser has been used to remove granular cell tumor with clear resection margin. This article describes one such case in a 62-year-old man, followed by a brief review of the literature on this subject.

Tracheal hemangioma is a rare benign vascular tumor in adults. We reported a case of massive hemoptysis caused by a cavernous hemangioma in a 75-year-old man. This is the first report, to our knowledge, of a tracheal cavernous hemangioma that presented with massive hemoptysis. The lesion was removed with a $CO_2$ laser under rigid laryngoscopy. Endovascular tumors, such as tracheobronchial hemangiomas, should be considered a diagnostic option in cases of massive hemoptysis without a significant underlying lung lesion.

Skeletal cavernous hemangiomas are rare, benign tumors that may involve the supraorbital rim and orbital roof. However, such involvement is extremely rare. We report a case of skeletal cavernous hemangioma of the frontal bone involving the orbital roof and rim. En bloc excision and reconstruction, using a calvarial bone graft for the orbital roof and rim defect, was performed. It is important not only to perform total excision of skeletal cavernous hemangiomas, but to properly reconstruct the defects after the total excision since several complications can arise from an orbital roof and rim defect.

We report a case of an 86-year-old man diagnosed with bilateral elastofibroma dorsi who was managed conservatively after a two year follow-up. An elastofibroma dorsi is a benign, slow-growing tumor that is most often located in the inferior periscapular area in elderly patients. It should be considered to differentiate them from other soft tissue tumors located at the inferior periscapular region. Increased awareness of these characteristics will decrease the incidence of a misdiagnosis of elastofibroma dorsi as a malignancy and avoid unnecessary surgery.

The fine needle aspiration (FNA) cytologic findings in 16 cases of histologically confirmed thymoma are reported. The aspirates were obtained under fluoroscopic guidance. The cytologic diagnoses were inadequate sample in one case, thymoma in 12(75%), small cell carcinoma or thymoma in 1, benign mesenchymal tumor in 1, and germ cell tumor in one. The cytologic features were detailed according to the constituent epithelial cell type, and into 4 small of epithelial cells and lymphocytes. Fifteen cases were classified into 4 small epithelial cell type, 6 intermediate epithelial cell type, 1 large epithelial cell type, 1 large pleomorphic epithelial cell type, and 3 spindle-shaped epithelial ceil type. Cytologic differential diagnosis was discussed, and the important criteria for the cytologic diagnosis of thymoma were reviewed. This review leads us to think that nonoperative cytologic approaches in the diagnosis of the thymoma are possible, and that correct cytologic diagnosis of thymoma with FNAs can easily be made, if adequate samples are obtained However the invasiveness and histologic type could not be predicted by cytological features only. Knowing various cytologic and histologic features of thymoma will be helpful for the diagnosis of thymoma and the differential diagnosis of modiastinal tumors.

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.

Epithelial-myoepithelial carcinoma (EMC) of the salivary gland is a rare tumor that comprises approximately 1% of all salivary gland tumors. It has a distinctive histological appearance comprising ductal structures with an inner epithelial cell component and an outer layer of myoepithelial cells. We report a case of EMC of the parotid gland in a 41- year-old man. He presented left-sided subauricular swelling developed 3-month earlier. Neck CT scans revealed a well-defined mass in the left superficial parotid gland. He underwent superficial parotidectomy and was diagnosed as EMC. He was taken postoperative radiotherapy. There was no evidence of recurrence during a follow-up period of 12 months. A EMC is a low grade malignant tumor which can cause diagnostic confusion during workup and also frequently misdiagnosed as other benign or malignant tumor.
