Diffuse cavernous hemangioma of the rectosigmoid is a rare lesion usually presented in children and young adult, often with life threatening hemorrhage. The clinical diagnosis is difficult and often delayed because of lack of awareness of the clinical features. We report a case of diffuse cavernous hemangioma of the rectosigmoid in a 12 year old boy who had undergone suture ligation under the impression of hemorrhoid at his age 3. Sphincter saving coloanal pull through procedure were applied as the surgical treatment. Sclerotherapy was needed with recurrent rectal bleeding 6 months after the pull through operation. The patient is well at 12 months follow-up.

We report a rare case of cavernous hemangioma (CH) which developed in adjacent location to a preexisting CH after gamma knife radiosurgery (GKRS). A 36-year-old woman underwent GKRS for a CH in the left lentiform nucleus. Three-and-half years after radiosurgery, MRI revealed a new CH in the left caudate nucleus. Surgical excision of the new lesion was performed. The pathological examination confirmed the diagnosis of CH. In radiosurgery for CH, it should be noted that a new CH may develop, which is likely to result from the interaction between radiation and predisposing factors of the patient.

Laryngeal hemangioma occurs mostly in infantile patients and infantile hemangiomas can be frequently seen in the subglottic area. So, respiratory distress is a main symptom in this entity. But adult hemangiomas are rare and can be seen in different locations such as in epiglottis, aryepiglottic fold, arytenoids and false and true vocal folds. Authors experienced a case of mixed hemangioma at the right aryepiglottic fold in a 42 years-old-man who was presented with snoring, throat foreign body sense for 3 months. So, we report this case with a review of the literature.

Sclerosing hemangioma of the lung is uncommon benign neoplasm of uncertain histogenesis. Their radiologic appearance is relatively distinct and well defined. Recently we experienced 3 cases of sclerosing hemangioma of the lung in 54, 52, 51 years old women. The light microscopic findings are similar to the features reported by Liebow and Hubbell(1956).

Intramuscular hemangiomas of the masseter muscle are uncommon tumors and therefore can be difficult to accurately diagnose preoperatively, due to the unfamiliar presentation and deep location in the lateral face. A case of intramuscular hemangioma of the masseter muscle in a 66-year-old woman is presented. Doppler ultrasonography showed a 34×15 mm hypoechoic and hypervascular soft tissue mass in the left masseter muscle, suggesting hemangioma. The mass was excised via a lateral cervical incision near the posterior border of the mandibular ramus. The surgical wound healed well without complications.

Hemangioma is a benign vascular proliferation. Intramuscular hemangiomas are rare, accounting for less than 1% of all hemangiomas, and occur normally in the trunk and extremities. Approximately 10-20% of intramuscular hemangiomas are found in the head and neck region, most often in the masseter muscles. The typical clinical characteristic is a painful soft tissue mass without cutaneous changes. The suggested treatment is a surgical excision. We report a case of an intramuscular hemagnioma of the masseter muscle. The patient was a 56 year old male who visited our clinic complaining of left facial swelling after 2 years of follow up at a different clinic. After magnetic resonance imaging (MRI), the mass was excised under general anesthesia. The biopsy revealed the mass to be an intramuscular hemangioma. We report the clinical and pathological characteristics as well as the treatment of a case of an intramuscular hemangioma of the masseter muscle.

The goal of this paper is that we know the usefulness of echo-planar imaging(EPI) for discriminate between hepatocellular carcinoma(HCC) and hemangioma. We get a time signal intensity curve for liver diseases from the dynamic contrast enhancement images and compared and analyze both the contrast ratio(CR) and the contrast to noise ratio(CNR) using echo planar imaging. The obtained results are follows : 1. Hepatocellular carcinoma was shown the best contrast after about 20 seconds when Is the earlist time in the main artery, and then reduced. The center where is disease was shown the characteristic that the best contrast is appeared after about 35-45 seconds and then slowly reduced. Liver parenchyma was shown the best contrast and reduced after 60 seconds. 2. The peripheral nodular of hemangioma was shown the better contrast soon. On the other hend, the contrast of center where is disease started to increase after 60 seconds and was equal to that of liver parenchyma. Increasing of the contrast continued after. 3. Turbo SE technic was used, the average of CR for hepatocellular carcinoma was $36.7{\pm}1.2$ and the average of CNR was $2.4{\pm}3.2$, while the average of CNR for hemangioma was $54.9{\pm}1.0$ and the average of CNR was $9.7{\pm}1.3$. 4. EPI technic was used, the average of CR for hepatocellular carcinoma was $47.8{\pm}1.2$ and the average of CNR was $3.4{\pm}2.1$, while the average of CNR for hemangioma was $75.7{\pm}2.2$ and the average of CNR was $9.5{\pm}1.1$. According to above we can find that hemangioma is more bright than hepatocellular carcinoma and the difference of brightness between hepatocellular carcinoma and hemangioma is useful sequence.

Radiation is a common treatment modality for central nervous system neoplasms. However, secondary tumor development must be considered in the differential diagnosis in patients with new or recurring symptoms after treatment with conventional radiotherapy. A 28-year-old woman developed a cavernous hemangioma about 9 years after brain irradiation for astrocytoma. Clinical and histopathological details are presented, and previous reports of radiation-induced intracranial cavernous hemangioma are reviewed.

Throughout the years, various classifications have evolved for the diagnosis of vascular anomalies. However, it remains difficult to classify a number of such lesions. Because all hemangiomas were previously considered to involute, if a lesion with imaging and clinical characteristics of hemangioma does not involute, then there is no subclass in which to classify such a lesion, as reported in one of our cases. The recent classification proposed by the International Society for the Study of Vascular Anomalies (ISSVA, 2014) has solved this problem by including non-involuting and partially involuting hemangioma in the classification. We present here five cases of vascular anomalies and discuss their diagnosis in accordance with the ISSVA (2014) classification. A non-involuting lesion should not always be diagnosed as a vascular malformation. A non-involuting lesion can be either a hemangioma or a vascular malformation depending upon its clinicopathologic and imaging characteristics.

Sclerosing hemangioma is a rare, benign neoplasm of the lung, usually presented as a solitary pulmonary nodule in an otherwise asymptomatic middle-aged woman. Cytologically it shows papillary, sheet, and cyst-like arrangements representing three main histologic patterns of papillary, solid, and angiomatous ones, respectively. Herein, we report the fine needle aspiration cytology of 5 cases of sclerosing hemangioma of the lung. The most characteristic finding is cyst-like spaces Intimately related to the papillary or solid cell nests. The tumor cells are relatively monotonous round to oval, small to medium in size. They have small amount of eosinophilic cytoplasm. The nuclei are uniform, round and have small but conspicuous nucleoli. The tumor cells in one of the presenting cases are large with abundant cytoplasm and show moderate nuclear pleomorphism. The nuclear chromatin, however, is fine and even without exception, even in the case showing nuclear pleomorphism. Major differential diagnoses based on the cytologic findings are well-differentiated papillary adenocarcinoma, bronchioloalveolar carcinoma, and carcinoid tumor.
