Benign cystic lesions, have to be differentiated, are common in the calcaneus, Among the lesions the intraosseous lipoma is extremely rare tumor in bone. In 1996, Unni reported 7 in 11,087 cases of bone tumors at Mayo Clinic. In Korea, Ahn reported the first intraosseous lipoma in the distal fibula. We experienced two cases of intraosseous lipoma of calcaneus, and report the clinical, radiological and pathological findings with a review of the literatures.

Lymphangiomas are uncommon benign congenital tumors. Most occur in the head and neck and most lesions present by the age of 2 years. We present our experience with four patients who have lymphangiomas of the head and neck with tongue involvement. First case is a 7-year-old male who has the cystic lymphangioma of left submandibular area. Second a 22-year-old female has a lesion involving the border of right tongue. Third case is the lymphangioma which occurs in the right upper lip of a 6-year old male. The last patient is a 28-year old male who fell down and whose right face was swollen up. He had undergone an operation and been treated with steroid before. The characteristic appearances of imaging methods were described and all lesions best depicted on T2-weighted images. Our experience indicates that MRI is useful in the diagnosis and treatment planning of lymphangioma.

Epithelial-myoepithelial carcinoma (EMC) is a rare type of low-grade malignant tumor that account for approximately 0.5% to 1% of salivary gland neoplasm and arises most commonly in the parotid gland (80%). We introduce three cases of parotid EMC arose as painless cystic mass in male patients over 70 years old. All patients were diagnosed as benign tumors (pleomorphic adenoma) by image and pathologic study (fine needle aspiration) before surgery, but the final histopathologic results were EMC. All three patients underwent parotidectomy without adjuvant radiotherapy. There were no complications such as facial paralysis. No complications or recurrences were observed during follow-up for 6 to 9 months. Since the reports of EMC are still relatively few, we report our three cases with the clinical and pathological review.

Lipoblastoma is a rare benign neoplasm occurring exclusively in children below the age of three years. It affects chiefly the upper and lower extremities, and less commonly head and neck area, trunk, mediastinum, mesentery, and retroperitoneum. We present two cases of lipoblastoma occurring in the mediastinum of a 21-month-old boy and in the back of a 15-month-old boy. The characteristic features of Fine needle aspiration cytology smears were the presence of immature fat cells in the form of spindle-shaped cells, stellate cells and vacuolated lipoblasts along with lipocytes against a myxomatous background. Two tumors were histologically confirmed to be lipoblastomas. Lipoblastoma can be cytologically diagnosed by considering the cytologic findings and the age of the patient.

Pulmonary hamartomas are uncommon benign tumors, usually discovered radiologically as a solitary coin lesion in asymptomatic individual. The approach to the patient with a peripheral lung nodule has changed with the increasing acceptance of fine needle aspiration cytology(FNAC) as a rapid, safe, inexpensive, and highly accurate diagnostic tool. However, a few reports describing the FNAC findings of pulmonary hamarioma have appeared in the cytologic literature and the experience of FNAC is limited. We reviewed all 9 cases of pulmonary hamartoma with histologic confirmation after FNAC seen at Asan Medical Center since 1995 to evaluate cytologic findings and to determine the value of FNAC in identifying that lesion. Originally, seven of nine patients were diagnosed as pulmonary hamartoma, while two patients were diagnosed as inflammatory lesion and adenocarcinoma of each. On review, eight of nine patients were considered as diagnostic of pulmonary hamartoma. The diagnostic findings in FNAC of pulmonary hamartoma were the presence of fibrillary myxoid tissue with spindle cells as well as hyaline cartilage.

유두상 섬유탄력종은 원발성 종양 중 두 번째로 많이 호발하는 양성종양으로 주로 심장판막에 발생한다. 본원에서는 심계항진과 호흡곤란을 주소로 내원한 51세 여자환자를 검사하던 중 우연히 대동맥 판막에 위치한 유두상 섬유탄력종이 발견되었다. 수술시 대동맥 판막의 손상 없이 대동맥 판막에 부착된 종양만 제거하는 것이 가능하였다.

Since. its first description by Albrecht in 1904 that hamartoma (Greek. meaning "error" and "tumor")is tumor-like malformation characterized by abnormal mixture of normal constituent in any organ it arises, hamartoma involving the lung has assumed the following clinical features.: 1) all the pulmonary lesions presenting as "coin lesions", it occupies about 8% according to various reports. It also constitutes the most prevalent lesion of all the benign lung tumors, appearing in 0.25% of the general population. 2) Peak incidence of the lesion occurs in the 5th and 6th decade as the carcinoma patient do, and the occasional growing tendency and periperal location as in this presentation renders the differential diagnosis from the malignant disease difficult and surgical intervention inevitable for definite histological diagnosis and treatment. 3) Nearly all the clinical investigations such as history, physical exam, bronchoscopy, culture, and cytological exam of sputum sre likely to futile:the only tool for detecting the presence of the lesion is X-ray, butthat's short of telling the true nature of it. 4) Because of its age of presentation and growing tendency in middle-aged adult, it still controversial whether it is developmental anomaly as Albrecht described, or true neoplasm denovo of fibrous connective tissue origin. This is a case report of surgical experience of pulmonary hamartoma which had nearly all the typical clinical features above mentioned and was reviewed with related literatures.

A subungual exostosis is an uncommon benign osteochondral lesion that appears as a painful nodule. Histologically, the tumors consist of a proliferating fibrocartilaginous cap that merged into mature trabecular bone at its base. From 1989 through 1991, 5 patients with subungual exostosis were treated. Three of them had exostosis on the great toe. There were three girls and two boys. The average age of the patients was 10.6 years. All of patients were treated by local excision. Two cases of our patients treated with an incomplete excision were recurred within 3 months after the original procedure. Lack of awareness of unusual lesion can cause initial misdiagnosis in many cases. We considered that a complete excision of the lesion is important for preventing the recurrence, and it should be confirmed with intraoperative radiographs.

The lateral rhinotomy signifies only an incision and not on operation and a lateral rhinotomy incision with osteotomy of the nasal bones provides access to the entire nasal cavity and maxillary, ethmoid, and sphenoid sinuses as well as the frontal sinus if the floor is removed, permitting removal of benign lesions at these sites and en bloc resection of the ethmoid labyrinth and the party wall between the nasal cavity and antrum with infiltrating tumors. The authors treated a tumor patient and a midfacial bone fracture patient via lateral rhinotomy approach and had a good result. So we report the cases with literature review.

Lymphangiomas are benign tumors of the lymphatic system characterized by congenital lymphatic malformation such as anastomosis or obstruction of the lymphatic channels. They are most frequently diagnosed in children younger than 2 years, and the lymphangiomas in head and neck represent about 50-75% of all lymphangiomas. Spontaneous regression is rare, and rapid enlargement occurs secondary to infection or trauma. Enlargement may cause serious sequence such as airway obstruction, feeding difficulties, and cosmetic problems. Treatments previously used for lymphangiomas include surgical excision and intralesional injection of sclerosing agents. Problems associated with surgical excision include the risk of scarring, damage to surrounding vital structure and the high risk of incomplete excision. The sclerosing agents previously used have numerous local and systemic side effects as their problems. We present a case of lymphangioma occured in tongue that was treated by surgical excision and sclerotherapy with OK-432.
