Purpose: Morel - Lavallee lesions is post - traumatic effusion at subcutaneous layer. Early management of Morel - Lavallee lesion is percutaneous drainage and compression. Surgical excision is recommended for cases that are chronic. Method: 41 - year old male patient had slow growing, painful mass on left thigh, which has been present for 3 years. He had a history of blunt trauma 3 years ago. Computed tomography presented $10{\times}10{\times}5cm$ sized cystic mass on left thigh, between subcutaneous fat layer and muscle fascia layer. The mass was surgically removed and biopsy was performed. Result: Histopathological examination shows chronic inflammation and fibrotic change. After 6 month follow - up period, postoperative course was uneventful. Conclusion: We performed surgical excision of Morel - Lavalle lesion in a patient who had trauma 3 years ago. We report a case of Morel - Lavallee lesion with the review of the literatures.

Fine needle aspiration cytology(FNAC) has become a popular method for the diagnosis of a wide variety of both superficial and deep-seated lesions. However, there are few reports about the potential of FNAC for the diagnosis of intraoral lesions. We experienced 44 FNACS from intraoral lesions at Asan Medical Center: 22 from the palate, 6 from the tongue, 5 from the parapharyngeal space, 5 from the lip, 2 from the floor of mouth, 1 from the buccal mucosa, and 3 from other intraoral sites. Histological confirmation was obtained in 32 cases and we analyzed 27 cases excluding 5 cases of inadequate aspirates. Diagnosis was specifically made in 19 of 27 cases(70%) including 1 mucoepidermoid carcinoma, 1 undifferentiated carcinoma, 1 chordoma, 9 pleomorphic adenomas, 1 neurofibroma, and 6 benign lesions. There were three false negative cases(sensitivity, 62.5%) and no false positive cases(specificity, 100%): Two cases diagnosed as "cystic lesion" were confirmed to be mucoepidermoid carcinomas and a case diagnosed as pleomorphic adenoma was proved to be adenoid cystic carcinoma. The results of our study suggest that FNAC is a useful technique in the diagnosis of intraoral lesion.

The mucocele is a mucus extravasation cyst arising from the salivary gland. Although it is a common?lesion of the minor salivary gland, it is uncommon when it originated from the submandibular gland. The ranula is a form of mucocele which specifically occurs in the floor of the mouth and the sublingual gland is generally accepted as the origin of ranula. They can be classified into two types based on extent: simple ranula are confined to the sublingual space and plunging ranula extend into the adjacent space. It is difficult to differentiate the submandibular gland mucocele from the plunging ranula because both of them can occupy the submandibular space. A 37-year old male visited our clinic with the chief complaint of left facial swelling. The patient's history revealed that he had suffered from a cystic lesion on the left side of the floor of the mouth 10 months previously. He supposed the cystic lesion had come from trauma at other dental clinics. Using CT and MRI, we diagnosed a simple ranula on the sublingual space and a submandibular gland mucocele. We then excised the mucocele with the submandibular gland by an extraoral approach and the sublingual gland by an intraoral approach under general anesthesia. We report a rare case of an enormous submandibular gland mucocele which extended into the pterygoid plate and parapharyngeal space with good surgical results.

Lymphangioma is a benign, growth of lymphatic tissue that is present at birth or develops in early childhood, which may cause serious alterations in growth and developmemt. The problems with facial lymphangioma is usually releated directly to their size and to the area of the face which is involved. The lesions themselves may range from small, localized blemishes to huge facial masses involving both soft tissue and underlying bone and causing great distortion and asymmetry. The facial bones are seldom involved, but the natutal evolution of an individual lesion often cannot be accurately predicted when the child is first seen. Any changes in the underlying facial bone could be due either to a direct growth of the lesion into the bone, or secondary to pressure of the lesion growing outside the bone itself. A case of cystic lymphangioma extending from the neck to the tongue is reported. A six-year-old female was admitted because of swelling of the tongue. At that time, the tongue reportedly reached the extraoral size of 7x5x2.5cm and a soft, diffuse swelling of left anterior neck was revealed. The removal of cystic mass including left neck dissection and partial glossectomy were undertaken. The another case of lymphangioma is located on mandibular cheek. A twenty nine-year-old male was admitted because of palpable mass of the left mandibular area and fissure of palate. The radical excision of mass with mandibulectomy of body were undertuken. Thus we reported such a rare case and reviewed the lymphangioma.

Basalold squamous carcinoma (BSC) is a rare, aggressive neoplasm of the upper aerodigestive tract or esophagus. It is characterized by a biphasic pattern in which basaloid tumor is intimately associated with a neoplastic squamous component which can be either Invasive r in situ. Despite its characteristic histologic appearance, the BSC of the esophagus has been confused with esophageal neoplasm variously reported as adenoid cystic carcinoma or carcinoma with adenoid cystic differentiation Their distinction is important because genuine adenoid cystic carcinoma is much less as- gressive than BSC. The biologic course of BSC is similar to that of the more frequent squamous cell carcinoma of the esophagus. We have experienced a case of BSC of the esophagus in a 60-year-old male patient. The lesion was located in the middle third of the esophagus. The patient was treated with surgery followed by radio- therapy.

Congenital cystic adenomatoid malformation of the lung is a rare pulmonary malformation, Although it is one of the most common congenital anomalies which cause acute respiratory distress in the newborn infants, characterized by marked proliferation of terminal respiratory structures. We have experienced an unusual case of congenital cystic adenomatoid malformation associated with pectus excavatum. The patient was 3-year-old female who suffered from cough and high fever for 20 days, and antibiotic therapy was given in other hospital before transfer to our hospital. The findings on chest X-ray, chest CT, aortogram, and selective bronchial arteriogram showed cystic lesions in the right upper and middle lobe accompanied but severe pectus excavatum. Right bilobectomy for pulmonary lesion and costosternal elevation for pectus excavatum was performed simultaneously with successful result. The postoperative course was uneventful and the patient was discharged on the twentieth postoperative day.

Authors report a case of cystic tuberculosis of left olecranon in a 44 year-old woman, which mimicked the bone tumor at initial presentation. She complained mild discomfort in the left elbow over a month. On examination there were no local redness, swelling, tenderness and deformity. There was no limitation of left elbow motion. After open curettage of the lesion, bone tuberculosis was confirmed by histological study. Postoperative triple chemotherapy of 12 months (Rifamcpicin, ethambutal, INH) could cure the disease.

Spinal neurenteric cysts are uncommon congenital lesions, furthermore solitary neurenteric cysts of the upper cervical spine are very rare. A 15-year-old boy having an intraspinal neurenteric cyst located at cervical spine presented with symptoms of neck pain and both shoulders pain for 2 months. Cervical spine magnetic resonance (MR) imaging demonstrated an intradural extramedullary cystic mass at the C1-3 level without enhancement after gadolinium injection. There was no associated malformation on the MR imaging, computed tomography, and radiography. Hemilaminectomy at the C1-3 levels was performed and the lesion was completely removed through a posterior approach. Histological examination showed the cystic wall lined with ciliated pseudostratified columnar epithelium containing mucinous contents. Neurenteric cyst should be considered in the diagnosis of spinal solitary cystic mass.

Epidermoid cyst is a cystic form of teratoma and believed to be derived from trapped embryonic cells along the lines of embryonic closure. A 28-year-old woman presented with a painless swelling over the left mandibular area. On panoramic view, the mandible revealed a $5.5{\times}2.0\;cm^2$ multilocular radiolucent lesion of the left mandibular body and a computed tomography scan showed expansion of both the buccal and lingual plates in the same area. Microscopy found stratified squamous epithelium of the cystic wall and cystic contents of keratinized material. The histological diagnosis wasan epidermoid cyst. The most common location of epidermoid cyst at the head and neck is in the orbit (47%), followed by the mouth floor (23%) and the cervical area (9~24%), but in the jaw bone, it is considered very infrequent. We report the uncommon epidermoid cyst in the mandibular body that had a good healing outcome after treatment with a conservative marsupialization during the 40 months follow-up.

Intraosseous lipoma is a benign tumor that originates from proliferating mature lipocytes. It often occurs in the metaphysis of long bones of the lower extremity, and also in the calcaneus, humerus, mandible, sacrum, and rib bones. Frequently, it involutes spontaneously through a process of infarction, calcification, and cyst formation. It can either present as pain, or be asymptomatic and only discovered through an incidental radiological finding. In our case, the patient presented with heel pain. Intraoperatively, it was found that the intraosseous cavity was filled with fat along with an adjacent but separate area of cystic degeneration. There was also a cortical perforation at the cystic lesion which was communicating with the subtalar joint. This cortical breach is most likely the cause of diffuse lateral heel pain experienced by our patient, and such a pathological fracture due to intraosseous lipoma has never been reported.
