A Case of Nasal Septal Abscess Originated from Dentigerous Cyst / 대한이비인후과학회지

Nasal septal abscess can result from various causes such as septal hematoma from septal trauma or hematologic disorder, and infections of surrounding structures like nasal vestibule, upper lip and other oral lesions and hematogenous spread of other infections. Dentigerous cyst is one of the common odontogenic cysts, associated with unerupted teeth, and usually asymptomatic. Symptoms of the dentigerous cyst present mostly oral or maxillomadibular lesions, whereas nasal symptoms of the dentigerous cyst is uncommon. We report an unusual case of dentigerous of a 61 year-old of the dentigerous cyst of mesiodens with nasal septal abscess.

Extraskeletal Mesenchymal Chondrosarcoma of the Heart Responded to Systemic Chemotherapy: A Case Report / Journal of the Korean Cancer Association, 대한암학회지

Mesenchymal chondrosarcoma is a rare cartilaginous neoplasm of an extraskeletal origin, and this predominately occurs in the head and neck, and also in the lower extremities. Fewer than twenty cases of cardiac mesenchymal chondrosarcoma have so far been reported on. For the most part, the results of treatment for patients with this condition have been dismal. In this study, we describe a case of cardiac mesenchymal chondrosarcoma that responded to chemotherapy following surgical biopsy. A 46-year-old man was referred for evaluation of his pleural effusions in both lungs. Chest computed tomography revealed an ovoid-shaped mass in the posterior wall of the patient's left atrium. The echocardiogram revealed a large ovoid-shaped immobile mass (11 x 6 cm2) in the pericardiac space, which was attached to the posterior wall of the left atrium. Emergency pericardiostomy with closure thoracostomy was performed. Seven days later, a thoracotomy was performed for reduction and diagnosis of the cardiac mass. The pathological diagnosis was extraskeletal mesenchymal chondrosarcoma of the heart.. Postoperative chemotherapy was performed for the huge remaining mass with a combined regimen of etoposide, ifosfamide and cisplatin. After 6 cycles, the patient showed a partial response without symptoms. Although cardiac mesenchymal chondrosarcoma has been reported to be chemotherapy- resistant with a short survival duration, chemotherapy may prove to be an effective treatment modality.

An Experience of Ballon Angioplasty in Hepatic Artery Stenosis After Living Related Living Transplantation

Liver transplantation is an accepted and successful mode of treatment for pediatric end-stage liver disease. Living related liver transplatation(LRLT) in child has certain potential advantages, such as short cold ischemic time, accurate graft size and vessel diameter match based on elective preoperative preparations. Recently, introduction of microvasular surgery technique to hepatic artery reconstruction has been used, but still remained the possibility of hepatic artery thrombosis. Herein, We report a LRLT case, which showed hepatic artery stenosis postoperatively, successfully dilated by ballon angioplasty technique.
