Primary cardiac tumors are rare disease and they present nonspecific symptom. They are divided in benign and malignant tumors and require surgical therapy and/or additional therapy. From March 1995 to March 2003, twenty one patients were diagnosed as having primary cardiac tumors. We analysed them retrospectively in terms of various perioperative factors and early and late results. 6 men and 15 women and their average age was 45.44$\pm$18.76. Pathology revealed eighteen benign (fourteen myxoma, two fibroelastoma, one hemangioma and one paraganglioma) disease and three malignant (one angiosarcoma, one mesothelioma and one myxofibrosarcoma) disease. There was one (myxoma) operative mortality and three late death (hemangioma, angiosarcoma and mesothelioma) during additional therapy and follow up. Surgical treatment of primary cardiac tumor is important and sometimes additional therapy is required but the prognosis of malignant cardiac tumor is still very poor.

Background The vermilion plays an important role in both the aesthetic and functional aspects of facial anatomy. Due to its structural features, the complete excision of vascular anomalies on the vermilion is challenging, making it difficult to determine the appropriate treatment strategy. Thus, the authors analyzed the results of surgical treatment of vascular anomalies on the vermilion. Methods The medical records of 38 patients with vascular anomalies on the vermilion who underwent surgery from 1995 to 2013 were analyzed. Nine of the cases had an involuted hemangioma, and 29 cases had a vascular malformation; of the vascular malformations, 13, 11, one, and four cases involved were capillary malformations (CMs), venous malformations (VMs), lymphatic malformations (LMs), and arteriovenous malformations (AVMs), respectively. We investigated the surgical methods used to treat these patients, the quantity of surgical procedures, complications and instances of recurrence, and self-assessed satisfaction scores. Results A total of 50 operations were carried out: 28 horizontal partial excisions, eight vertical partial excisions, and 14 operations using other surgical methods. All cases of AVM underwent complete excision. Six cases experienced minor complications and one case of recurrence was observed. The overall average satisfaction score was 4.1 out of 5, while the satisfaction scores associated with each lesion type were 4.2 for hemangiomas, 3.9 for CMs, 4.2 for VMs, 5.0 for LMs, and 4.0 for AVMs. Conclusions It is difficult to completely excise vascular anomalies that involve the vermilion. This study suggests that partial excision focused on correcting the overall contour of the lips is effective and leads to satisfactory results.

Objective: The goal of this study is to provide the clinical data of patients with brainstem cavernous hemangiomas after treatment with microsurgery or radiosurgery after conducting a retrospective analysis of 21 patients at one institution. Methods: Twenty one patients with brainstem cavernous hemangiomas were treated at the authors' institution between 1995 and 2004 and clinical analysis was performed by retrospective review of medical records and neuroimaging examinations. Thirteen patients underwent microsurgical resection and radiosurgery was performed as an initial treatment in 9 patients. Results: Radical excision was achieved in 12 among 13 patients and transitory neurological deterioration or new neurological deficit developed during the immediate postoperative period in 7 (54%). The final outcomes at 5 - 70 months after surgery were improved in 11 patients (85%) and worsened in 2 patients (15%) compared with the preoperative state. Radiosurgery was performed in 9 patients. During the follow up period from 5 to 70 months there was neurological improvement in 3 patients, no significant change in 3 and deterioration in 3 patients. Two patients developed rebleeding at 5 months, 60 months respectively after radiosurgery. Conclusion: Microsurgery for symptomatic cavernous hemangioma of brainstem can be performed with acceptable morbidity. Fatal complication is rare with careful selection of the optimal operative approach in well selected patients. Radiosurgery is an effective alternative for the lesions which are not accessible by surgical approach, however, there is still a possibility of rebleeding over a long period after radiosurgical treatment and microsurgery should be considered as a treatment with priority for the majority of cases.

Fine needle aspiration (FNA) cytological examination is an appropriate method for the evaluation of pulmonary nodules. In major types of lung cancer, Its diagnostic accuracy is quite high. However, it is sometimes difficult, using this technique, to differentiate between some unusual phenotypes including adenosquamous carcinoma, bronchioloalveolar carcinoma (BAC), neuroendocrine tumor, mucoepidermoid carcinoma, and sclerosing hemangioma. Here, we present a case involving extremely well differentiated adenosquamous carcinoma, mimicking benign lesions, such as pulmonary scar and adenomatoid malformation with squamous metaplasia. The patient was a 68-year-old man presenting with a solitary pulmonary nodule$(1.6\times1.6cm)$, which was incidentally found at the periphery of the right lower lobe. FNA revealed some clusters of glandular cells with minimal atypia, in addition to squamous cells at a nearly full maturational state. Histological examination verified the cytological diagnosis on a lobectomy specimen. The tumor exhibited a well differentiated adenocarcinoma component, mimicking the bronchioles in scarred lung tissue. and a well differentiated squamous cell carcinoma component, mimucking the squamous cell nests of adenoacanthoma, in the other organs. In the present case, the possibility of adenosquamous carcinoma should have been considered if squamous cells were seen in the FNA from the peripheral pulmonary nodule, even though they appeared to be benign.

Klippel-Trenaunay syndrome is a rare mesodermal phakomatosis characterized by cutaneous haemangiomata( usually unilateral and involving an extremity), venous varicosities and osseous and soft tissue hypertrophy, of the affected limb. Sturge-Weber syndrome, also a mesodermal pharkomatosis, is characterized by a port-wine nevus, which is present from birth and covers the face and cranium in the territory of the first division of the trigeminal nerve. Homolateral to the skin lesion, there is atrophy and calcification of the cerebral hemisphere. We experienced an unusual 26-months-old female, who had features of both Klippel-Trenaunay syndrome and Sturge-Weber syndrome. She had an extensive nevus flammeus which extended primarily over both sides of her face and the right side of the trunk and extremities, hypertrophy of the right extremity without evidence of arterovenous fistula, right glaucoma, choroidal hemangioma and leptomeningeal hemangioma, which combined Klippel-Trenaunay syndrome and Sturge-Weber syndrome. We reported this rare case with a brief review of some related literatures.

The soft tissue tumors that occur commonly in newborn infants include palatal and gingival cyst of the newborn, congenital epulis, hemangioma, teratoma, pyogenic granuloma, and irritation fibroma. Such soft tissue tumors in the alveolar ridge of newborns are usually treated by surgical excision. If untreated, they can cause airway obstruction and breathing difficulty due to aspiration. They also cause discomfort during oral feeding. If nasal feeding is tried, since vomitting is impossible, there is a risk of aspiration pneumonia. In this case, a newborn infant visited our hospital with soft tissue tumor as chief complaint, and the infant was treated by surgical excision. It appeared to be similar to pyogenic granuloma and irritation fibroma upon histologic exam. However, it was different from those diseases since multinucleated giant cells were observed and it was congenital. The pathologic process of this neoplasm is not clear. This case is reported, since it is difficult to classify it as a specific disease.
