종격동에 발생하는 혈관종은 전체 종격동 종양의 0.5% 이하로 드문 양성 질환이다. 이중 모세관혈관종과 해면혈관종이 90% 이상을 차지하고 정맥혈관종은 국내에선 보고된바 없으며 세계적으로도 보고된 예가 드물다. 44세 여자 환자가 대장암 수술 후 추적관찰을 위해 시행한 흉부 전산화 단층촬영상 종격동 종괴가 우연히 발견 되었다. 우리는 이를 고형체로 의심하고 종격 내시경하 조직검사를 시행하던 중 출혈이 발생하여 개흉술로 전환한 후 완전 절제한 정맥 혈관종을 경험하였기에 이를 보고하는 바이다.

Primary tumors arising from the external auditory canal (EAC) are rare. We describe two cases of mass lesions within the EAC causing slowly progressive hearing loss without otorrhea or otalgia. Otoendoscopic examination demonstrated total obstruction of the EAC, and pure tone audiometry revealed conductive hearing loss. Based on the findings of the histopathologic examination, one patient was diagnosed with venous hemangioma that was treated using surgical resection, and the other patient was diagnosed with diffuse large B-cell lymphoma (DLBCL) that was treated using external-beam radiation therapy. Although primary tumors in the EAC are rare, both benign tumors such as venous hemangiomas and malignant lesions such as DLBCL should be considered as possible differential diagnoses of mass lesions in the EAC.

Venous malformations arising from the peripheral nerve are a rare type of vascular malformation. We present the first case of an intraneural venous malformation of the median nerve to be reported in a child and review the previous two cases of median nerve compression due to a venous malformation that have been reported. These cases presented with painless masses in the volar aspect of the wrist or with symptoms suggestive of carpal tunnel syndrome. Clinical suspicion should lead to the use of Doppler ultrasonography as the first-line diagnostic tool. Magnetic resonance imaging and histopathology can confirm the diagnosis, as phleboliths are pathognomonic of venous malformations. Surgical treatment appears to be the only modality capable of successfully controlling the growth of an intraneural malformation. Sclerotherapy and radiotherapy have never been used to treat this type of malformation.

Lymphangiohemangiomas of the mediastinum are exceedingly rare and few cases have been published in the English literature. This report may be the only reported case in which lymphangiohemangiomas were found bilaterally. We report a case of a 7-year-old boy with an incidental finding of an abnormal mediastinal shadow on a chest X-ray. The chest CT showed a large mass in the left superior mediastinum and another in the right posterior mediastinum. The left mass had anomalous venous channels connected to the left innominate vein, and the right mass to the left atrium. We performed an excision of the mass in the left side first and then the right side one month later. Anomalous venous channels were dissected carefully and ligated. There were no complications and no signs of recurrence 30 months after the operation.

Vascular malformations are structural abnormalities that are thought to result from errors in vasculogenesis and angiogenesis during embryogenesis. Vascular malformations of the scalp present unique management challenges due to aesthetic and functional implications. This review examines the pathophysiology, clinical presentation, and management techniques for six common types of vascular malformations of the face and scalp : infantile hemangioma, capillary malformations, venous malformations, lymphatic malformations, arteriovenous malformations, and arteriovenous fistulas. These lesions range from common to rare, and have very different natural histories and management paradigms. There has been increasing understanding of the molecular pathways that are altered in association with these vascular lesions and these molecular targets may represent novel strategies of treating lesions that have historically been approached from a structural perspective only.

Giant cavernous malformations (GCMs) occur very rarely and little has been reported about their clinical characteristics. The authors present a case of a 20-year-old woman with a GCM. She was referred due to two episodes of generalized seizure. Computed tomography and magnetic resonance image demonstrated a heterogeneous multi-cystic lesion of $7\times5\times5$ cm size in the left frontal lobe and basal ganglia, and enhancing vascular structure abutting medial portion of the mass. These fingings suggested a diagnosis of GCM accompanying venous angioma. After left frontal craniotomy, transcortical approach was done. Total removal was accomplished and the postoperative course was uneventful. GCMs do not seem differ clinically, surgically or histopathologically from small cavernous angiomas, but imaging appearance of GCMs may be variable. The clinical, radiological feature and management of GCMs are described based on pertinent literature review.

Cavernous lymphangioma is a benign tumor of lymphatic origin encountering most frequently in young children, and composed of softly fluctuated monolocular or multilocular cystic masses which developed from embryonic outpouching of the venous system. The prevailing site of this tumor Is at the anterolateral neck region particularly posterior triangle, and occasionally axillary, mesentery and spleen etc. Recently, we have experienced one case of left axillary cavernous lymphangioma, which surgically removed successfully and confirmed histopathologically. We want to report one case of left axillary large cavernous lymphangioma with a brief review of the relevant literatures.

Hemangioma and vascular malformation are the most common benign tumors that are caused by congenitally or traumatic events. Theses tumors represent approximately 1/3~1/4 of all hemangiomas and vascular malformations in the head and neck. There are many forms of treatment for hemangioma and vascular malformation including closed observation, surgery, radiotherapy, laser therapy, steroid therapy, compression, embolization, and sclerotherapy. Ethanolamine oleate is an unsaturated fatty acid salt that has been used as a sclerosing agent because of its excellent thrombosing properties. This paper presents 1 case of intraoral multiple venous malformations treatment with 1.25% ethanolamine oleate (3.6~9.6 mg dose) intralesionally injected for 6 to 14 weeks over 2 week intervals. After the sclerotherapy, lesions almost completely disappeared without side effects. In conclusion, sclerotherapy using ethanolamine oleate is very effective against venous malformations, and sufficiently provides alternative support for surgical and other methods.

Vascular malformations (VMs) in the head and neck region are present at birth and grow commensurately with the child, they can result in significant cosmetic problems for the patient, and some may lead to even serious life threatening hemorrhage. Although the molecular mechanisms underlying the formation of these VMs remain unclear, lesions are known to result from abnormal development and morphogenesis. Histologically, there are no evidence of cellular proliferation, but rather progressive dilatation of abnormal channels, which VMs are designated to their prominent channel types such as capillary, venous, lymphatic, arterial, and combined malformations. VMs with an arterial component are rheologically fast-flow, whereas capillary, lymphatic, and venous components are slow-flow. In this article, we review the clinical presentations, diagnosis, and management of VMs of facial regions with author's embolization and surgical treatment cases.
