An intraosseous hemangioma of the frontal bone is typically removed via a coronal incision. This procedure, while effective, can be lengthy and may result in complications such as a prominent scar and hair loss. An alternative approach involves a direct incision in the forehead, which leaves a less noticeable scar and allows a quicker recovery. However, in this specific case, the patient declined both coronal surgery and surgery through a direct forehead incision due to cosmetic concerns. Therefore, we proposed an anterior hairline incision. A 35-year-old woman presented with a firm, non-mobile, palpable mass on her right forehead. Preoperative non-contrast computed tomography revealed a heterogeneous osteolytic lesion. We performed an excisional biopsy through the anterior hairline. Postoperative non-contrast computed tomography was conducted 2 and 6 months after surgery. The wound was clean and free of complications, and there was no local recurrence. Partial resection can reduce scarring for patients who are concerned about cosmetic outcomes. However, the potential for recurrence remains a significant concern. We present this case of an anterior hairline incision for a hemangioma located in the forehead, evaluated using serial computed tomography for both preoperative and postoperative imaging.

Schwannomas originate from the Schwann cells in the neural sheath of the peripheral nerves. Ancient schwannoma is one of five variants, and its characteristics include histopathological degeneration and diffuse hypocellular areas. Histopathological features show degenerative changes and atypical nuclei can easily be confused with malignant neoplasms. These cellular atypisms are caused solely by degenerative changes. Ancient schwannomas have been reported 17 cases of in the oral cavity and five cases in the ventral tongue, including the floor of the mouth. We report a new case of an ancient schwannoma, misdiagnosed as a hemangioma with a 10-year evolution, located in the ventral tongue of a 29-year-old female.

Background: Hemangioma and vascular malformation are benign vascular lesions that often occur in cephalic and cervical region. Currently, surgical resection, laser therapy, angiographic embolization, use of steroids, and sclerotherapy are used as treatments. Case presentation: This study reports three cases of benign vascular lesions that are remarkably treated by sodium tetradecyl sulfate (STS) injection, of which occurred in oral cavity and around the mouth. Three percent of STS was diluted with 0.9 % of normal saline, and it was injected to the lesion site at least once. The result of treatment was evaluated based on clinical findings. Conclusion: Surgical treatment of hemangioma and vascular malformation occurred in oral cavity is not normally used because of esthetic issues and potential hemorrhage. On the other hand, sclerotherapy using STS is an effective therapy compare to surgical treatment. Despite the number of STS injection was different for each patient, all three patients had reached satisfactory level through the treatment with gradual diminution of lesions.

A case of pneumocytoma(so-called sclerosing hemangioma) with regional Iymph node metastasis is reported. A round lesion in the right hilar region was incidentally found in a 29-year-old man. He underwent right upper lobectomy and Iymph nodes dissection with preoperative impression of bronchogenic adenocarcinoma. The tumor was well circumscribed with characteristic histological feature of sclerosing hemangioma. Several Iymph nodes contained metastatic deposits of proliferating pale cells with formation of glandular spaces. A Ithough pneu ocytoma is said to be benign, quite rare cases apparently show metastatic potential.

Extracerebral cavernous hemangiomas are rare vascular tumors that are very difficult to remove because of severe intraoperative bleeding. We report a case of 57-year-old male with extracerebral cavernous hemangioma with review of 126 cases in the literature. Patient presented with blurred vision, diplopia, numbness on the left side of his face. Magnetic resonance imaging revealed a well defined mass of $3{\times}4{\times}3cm$ size with heterogenous iso-or hypointensity on T1-weighted image showing strong homogenous contrast enhancement and marked hyperintensity on T2-weighted image. Digital subtraction angiography[DSA] revealed a faint tumor blush by feeders from the left internal carotid artery[ICA] and left external carotid artery[ECA] in the delayed phase. Even with profuse intratumoral bleeding, near total removal was achieved. In addition to preoperative neurologic deficits such as ophthalmoplegia, facial numbness in the V1-2 dermatomes, ptosis appeared postoperatively.

The lobular capillary hemangioma (LCH) was previously known to pyogenic granuloma and is benign vascular lesion which grows rapidly on skin and mucosa. It arises from whole body, but oral and nasal cavities are most predilection sites in the head and neck area. The laryngeal LCH looks like a granulomatous lesion of posterior glottis and its common etiology are tracheal intubation and laryngopharyngeal reflux disease etc. The LCH in larynx can cause blood tinged sputum and lump sense. The lesions refractory to medical therapy or causing dyspnea may require surgical excision. A 74-year-old man who presented gradually aggravated dyspnea, lump sensation and hoarseness of one month came to our hospital. The stroboscopic examination revealed large well-margined glottic mass. It was excised with $CO_2$ laser and finally diagnosed as LCH. We present a rare unique case of glottic LCH with a review of literatures.

Intracardiac hemangiomas are very rare primary cardiac tumor and there have been at least 37 reports of surgically resected cardiac hemangiomas. Most cardiac hemangiomas are asymptomatic. In symptomatic patients, symptoms are related to the location of tumor and outflow tract obstruction or obstruction of inferior and/or superior vena cava. Sudden death may occur due to conduction disturbances. The principle of treatment is surgical resection, and the prognosis is dependent upon the size, location and multiplicity of the tumor. A 40 year old man was admitted due to chest contusion and was found to have an intracardiac mass during echocardiographic examination. The mass was successfully removed and pathologic examination showed benign hemangioma. The patient was recovered uneventfully in postoperative period and was followed up for 1 year without evidence of recurrence.

Objective: To document the imaging findings of hepatic cavernous hemangioma detected in cirrhotic liver. Materials and Methods: The imaging findings of 14 hepatic cavernous hemangiomas in ten patients with liver cirrhosis were retrospectively analyzed. A diagnosis of hepatic cavernous hemangioma was based on the findings of two or more of the following imaging studies: MR, including contrast-enhanced dynamic imaging (n = 10), dynamic CT (n = 4), hepatic arteriography (n = 9), and US (n = 10). Results: The mean size of the 14 hepatic hemangiomas was 0.9 (range, 0.5-1.5) cm in the longest dimension. In 11 of these (79%), contrast-enhanced dynamic CT and MR imaging showed rapid contrast enhancement of the entire lesion during the early phase, and hepatic arteriography revealed globular enhancement and rapid filling-in. On contrast-enhanced MR images, three lesions (21%) showed partial enhancement until the 5-min delayed phases. US indicated that while three slowly enhancing lesions were homogeneously hyperechoic, 9 (82%) of 11 showing rapid enhancement were not delineated. Conclusion: The majority of hepatic cavernous hemangiomas detected in cirrhotic liver are small in size, and in many, hepatic arteriography and/or contrast-enhanced dynamic CT and MR imaging demonstrates rapid enhancement. US, however, fails to distinguish a lesion of this kind from its cirrhotic background.

The authors reviewed and analyzed the pathologically confirmed 230 cases of benign soft tissue tumors which had been treated at Department of Orthopaedic Surgery in Seoul Hospital, Hanyang University College of Medicine from February 1984 to November 1997. The following results were obtained. 1. The most common benign soft tissue tumors was ganglion(26.5%) followed by hemangioma(19.6%), lipoma(17.0%), Baker's cyst(13.0%) and neurilemmoma(7.0%) in decreasing order of incidence. 2. Benign soft tissue tumors were found evenly distributed over all age group. Hemangioma and lymphangioma were usually found to occur before 20 years old. 3. Female was affected about 1.3 times more common. But, Baker's cyst and neurilemmoma occurred most frequently in male. 4. In children, the most common benign soft tissue tumors was hemangioma followed by ganglion, lymphangioma, and lipoma. In adult, ganglion, lipoma, Baker's cyst, hemangioma were common. 5. The lower extremity was the predominant site of occurrence(60.0%). 6. Benign soft tissue tumors were taken by excision. Local recurrences were developed in 22(9.6%) out of 230 cases, especially in hemangioma.

Purpose: RBC blood pool SPECT has been used to diagnose focal liver lesion such as hemangioma owing to its high specificity. However, low spatial resolution is a major limitation of this modality. Recently, ordered subset expectation maximization (OSEM) has been introduced to obtain tomographic images for clinical application. We compared this new modified iterative reconstruction method, OSEM with conventional filtered back projection (FBP) in imaging of liver hemangioma. Materials and Methods: Sixty four projection data were acquired using dual head gamma camera in 28 lesions of 24 patients with cavernous hemangioma of liver and these raw data were transferred to LINUX based personal computer. After the replacement of header file as interfile, OSEM was performed under various conditions of subsets (1,2,4,8,16, and 32) and iteration numbers (1,2,4,8, and 16) to obtain the best setting for liver imaging. The best condition for imaging in our investigation was considered to be 4 iterations and 16 subsets. After then, all the images were processed by both FBP and OSEM. Three experts reviewed these images without any information. Results: According to blind review of 28 lesions, OSEM images revealed at least same or better image quality than those of FBP in nearly all cases. Although there showed no significant difference in detection of large lesions more than 3 cm, 5 lesions with 1.5 to 3 cm in diameter were detected by OSEM only. However, both techniques failed to depict 4 cases of small lesions less than 1.5 cm. Conclusion: OSEM revealed better contrast and define in depiction of liver hemangioma as well as higher sensitivity in detection of small lesions. Furthermore this reconstruction method dose not require high performance computer system or long reconstruction time, therefore OSEM is supposed to be good method that can be applied to RBC blood pool SPECT for the diagnosis of liver hemangioma.
