Since sclerosing hemangioma of the lung was first described by Liebow and Hubbell in 1956, there have been several reports on cases occurring as a solitary nodule; however, sclerosing hemangiomas occurring as multiple nodules are extremely rare. The histogenesis of this tumor remains controversial and there are several hypotheses of the etiology. Three separate nodules were found in a 57-year-old housewife, one found in the right middle lobe, one in the apicoposterior segment of the left upper lobe, and one in the superior segment of the left lower lobe. The only symptom or sign presented was a dry cough. Apicoposterior segmentectomy of the left upper lobe and wedge resection of the superior segment of the left lower lobe were performed. The postoperative course was uneventful and the patient was discharged on the postoperative 15th day.

Hemangioma is one of the most common congenital tumors in the region of the face and neck. Although histologically benign, these facial masses are clinically malignant for their deforming and inexorable growth, especially in so-called 'cavernous hemangioma'. Carvenous hemangioma is the most common primary tumor occurring in the adult orbit. This tumor has symptoms that characteristically develop over several years with slowly progressive proptosis, eyeball deviation, hyperopia, diplopia and optic nerve compression. Today, hemangiomas are being treated by various methods; steroids, electrocoagulation, injection of sclerosing agent, cryotherapy, radiation therapy, laser therapy, and surgical treatment, etc. In principle, surgical approaches to the orbit must provide maximum safety and optimal visualization. We have experienced a case of large cavernous hemangioma in the orbit inferolaterally. The surgical treatment of tumor was achieved by the bicoronal approach combined with inferomedial and inferolateral orbitotomy. This surgical approach allows better visualization of the tumor and greater protection of essential anatomic structures. We obtained satisfactory results in terms of aesthetic and functional consideration. We present our case with a brief review of the literature related to orbital cavernous hemangioma.

Pulmonary sclerosing pneumocytoma (PSP) is a tumor of pneumocytic origin that is classified as a benign neoplasm. To date, aggressive behavior of this tumor has rarely been reported. Here, we describe a case of a 56-year-old woman with a huge, 19-cm PSP that resulted in mediastinal shift and showed microscopic endobronchial invasion and necrosis. The differential diagnosis included malignant mesenchymal tumors, such as solitary fibrous tumor; however, PSP was confirmed based on the characteristic thyroid transcription factor 1 positivity and membranous expression of Ki-67 on immunohistochemical staining of tumor cells.

Video thoracoscopic surgery is a new modality that gains acceptance rapidly from thoracic surgeons. We have experienced two left lower lobectomies, one left upper lobectomy & one right upper lobectomy with using video thoracoscopy for the four patients with lung parenchymal disease from July 1992 to February 1993. The post-operative courses were uneventful. The final pathologic diagnosis were sclerosing hemangioma, adenocarcinoma, bronchiectasis, leiomyoma & the post-operative courses were short. These patients needed less analgesics because postoperative pain was reduced markedly, and hospitalization was shortened due to rapid recovery. We would like to prefer video thoracoscopic lobectomy to the lobectomy through standard thoracotomy in uncomplicated patients with simple pulmonary parenchymal diseases.

We have experienced 59 cases of videothoracoscopic operation for 7 months from January to August 1992 at Yongdong Severance Hospital, Yonsei University College of medicine. There were pneumothorax in 21 cases, mediastinal mass in 12 cases, diffuse intestitial lung disease in 7 cases, Buerger's disease in 1 case, metastatic lung cancer in 1 case and sclerosing hemangioma in 1 case. We had performed a variety of procedures (bullectomy in 21 cases, sympathectomy in 17 cases, mass excision in 12 cases, lung biopsy in 8 cases, lobectomy in 1 case). The patients were uneventful in post-operative courses.

The hemangioma, a benign proliferation of blood vessel, is the most common tumor of infancy and childhood. In many instances, the lesion probably represents a hamartoma or malformation rather than a true neoplasm. In the oral cavity, common sites are lips, followed by tongue, buccal mucosa and palate. Clinical characteristics appear as a flat or raised reddish-blue lesion and are generally solitary. They are classified on the basis of their histological appearance into capillary, mixed, cavernous or a sclerosing variety. A 6-year-old male of this case was referred to the Department of Pediatric Dentistry, Chonnam National University with a chief complaint of swelling lesion on gingiva. The strawberry appearance mass was detected by clinical examination on attached gingiva at the upper left primary lateral incisor and canine. Surgical excision and biopsy were carried out for histological examination and the lesion was diagnosed with a capillary hemangioma. The risk of recurrence after this therapy is rare, and there is no malignant transformation. Despite their benign origins and behaviour, hemangiomas in the region of oral cavity are always clinically important to the dental profession because of bleeding tendency.

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.

Background: Pulmonary sclerosing hemangioma is rare, but still the second most common benign lung tumor, occurring most1y in middle-aged women. Methods: From January 1985 through April 1993, we experienced eight cases of solitary pulmonary sclerosing hemangioma. Results: Subjects studied were 7 female and 1 male patients. They ranged from 14 to 63 years of age(mean age, 43.8 years) at the time of operation. The patients were frequently asymptomatic and the tumor was often shown to be a large lobulated mass on radiographic examination. The tumor can usually be diagnosed on operation because of its subtle clinical and radiographic presentation. All eight cases were diagnosed intraoperatively. The mean interval between initial radiographic detection and operation was 7.9 months. Out of 8 cases, preoperative impression of benign tumor was made in 4 cases, whereas malignant tumor was suspected in the remaining 4 cases. Enucleation, wedge resection or lobectomy was performed which appropriate in each patient. Conclusion: Surgical removal of the tumor preserving as much lung parenchyma as possible is indicated for proper diagnosis and treatment of this condition.
