Vascular anomalies include a wide range of tumors and malformations. Among vascular anomalies, hemangioma is the most common. Hemangioma is considered as hamartomatous lesion, and half of these have predilection for head and neck region, but rarely seen in the oral cavity. Here, we report a case of hemangioma in the posterior third of the tongue in a 10-year-old female, which appeared localized well defined, reddish pink and lobulated mass with well-defined margins on intra-oral examination. A well-defined homogeneously hyperechoic space occupying lesion (measuring = 4.4 cm × 4.2 cm) seen on ultrasonography which showed abnormally increased vascularity on color Doppler suggesting a vascular etiology. Further evaluation was done on contrast enhanced computed tomography scan and magnetic resonance imaging, which confirms its vascular nature and diagnosed as a case of hemangioma.

| Introduction|| |
Hemangioma (Greek: Haima-blood; angeion-vessel, oma-tumor) is defined as a tumor of dilated blood vessels. They are most common vascular tumors of infancy and childhood. , Hemangioma are of two types-capillary and cavernous. They appear in the 1 st month of life and are characterized by rapid proliferative phase and slow involution, to near spontaneous resolution. Nearly 60-70% of the lesions are found in head and neck. 
Hemangiomas can also be described according to the vessel involved or flow type like arterial or arteriovenous type (high flow) or capillary or venous type (slow flow). 
| Case Report|| |
A 10-year-old girl visited our hospital for a localized swelling on the posterior third of the tongue. The swelling was present since 1½ years back, it was small at first but gradually increased in size. Patient had difficulty in swallowing and breathing due to the swelling no history of pain, fever, and bleeding was present. On general examination, the built of the patient was normal for age, and all the vitals were normal. No relevant medical, dental and family history was present.
Intra-oral examination revealed a localized well defined, reddish pink and lobulated mass with well-defined margins in the posterior third of the tongue extending up to the right tonsilo-lingular sulcus measuring approximately (5 cm × 6 cm) [Figure 1]. The surface was smooth with fine granularity. On palpation, it was soft to firm in consistency nonmobile, afebrile, nontender with no thrill and blanched on application of pressure. Routine blood, urine and thyroid profile were normal. On X-ray lateral view skull showed increased soft tissue shadow in the oropharynx. On high resolution ultrasonography of tongue through submandibular approach revealed a well-defined homogeneously hyperechoic space occupying lesion (SOL) (measuring = 4.4 cm × 4.2 cm) in the posterior third of tongue, the SOL showed abnormally increased vascularity on color Doppler suggesting a vascular etiology [Figure 2]. On computed tomography (CT) scan of neck, a well-defined moderate sized homogenously iso to hyperdense SOL with clear margins which showed strong homogenous enhancement on post contrast scans [Figure 3], involving the base of the tongue and floor of mouth causing narrowing of the oropharyngeal region extending posteriorly up to the pre styloid parapharyngeal space, no evidence of any bony destruction was noted. On magnetic resonance imaging (MRI) a well-defined rounded area of signal alteration iso to hypointense on T1-weighted, hyper-intense on T2-weighted with multiple serpiginous flow voids with strong homogenous enhancement on contrast with marked enhancement of intra-tumoral vessels is noted at the base of tongue extending up to the oropharynx [Figure 4]. Excision of the lesion was done with no postoperative complications. With all the investigations, a diagnosis of hemangioma of tongue was concluded.

| Discussion|| |
Hemangiomas are common developmental vascular abnormalities, head and neck regions are more commonly involved mainly face, lips and oral mucosa, but the tongue is rarely involved as in our case report. The term "hemangioma" is misused for various vasculoformative tumors, for this confusion, the International Society for the Study of Vascular Anomalies has recently provided guidelines to differentiate these two conditions, according to the novel classification first published by Mulliken and Glowacki in 1982.  Now vasculoformative tumors are divided into Hemangioma and vascular malformations. Hemangiomas are benign tumors of endothelial cells and are of two types capillary and cavernous hemangioma. Histologically hemangiomas are classified as capillary and cavernous types. A capillary hemangioma also called as "strawberry" birthmark consists of an abnormal overgrowth of tiny blood vessels. Capillary hemangiomas may not be present at birth but appear within the first 6 months of life. They usually begin to decrease in size between 12 and 15 months of age. Most regress nearly completely by 5 or 6 years of age. Capillary hemangiomas are more common in premature infants and in girls while cavernous hemangioma is a benign, congenital red or purple tumor consisting of enlarged blood vessels. The scalp, face, and neck are the most common sites, but these tumors have been found in the liver and other organs. Superficial cavernous hemangiomas are friable and easily infected if the skin is broken. Treatment includes observation, irradiation, sclerosing solutions, and laser surgery and excisional surgery. Cavernous hemangiomas are also called as angioma cavernosum, cavernoma.  Hemangiomas are dark red to purplish blue, may be superficial or deep, may be sessile or pedunculated, they blanch on application of pressure, can vary from millimeters to centimeters in size. ,
Radiological investigations are mainly done if the tumor is compressing a vital anatomical structure like a nerve or a vessel. CT and MRI are used for assessing the volume of hemangiomas and vascular malformations and can also help to differentiate the tumor from its differentials and also help in assessing the its size, extension and location, as well as for follow-up after treatment. Color Doppler can help in differentiating between vascular and nonvascular lesions and can help to localize the feeding vessel, further helping in concluding the treatment plan. Baba and Kato reported a case of hemangioma with pleboliths in the floor of the mouth and Doppler ultrasonography, CT, MRI was used to diagnose the lesion. 
Hemangiomas are found in association with various syndromes like Osler - Webber - Rendu syndrome, Sturge - Webber syndrome and Blue rubber bleb nevus syndrome. Differential diagnosis in our case could be lingual thyroid, thyroglossal duct cyst, lymphangioma, hypertrophy of ligular tonsils, dermoid and lipoma. The presence of vascularity in hemangioma differentiates it from the above condition.
Hemangioma of tongue needs special consideration due to susceptibility to trauma, bleeding and ulceration, it may also become a cause of difficulty in breathing and dysphagia.
Most of the haemangiomas are asymptomatic and can be treated conservatively. If symptoms like mass effect, dysphagia, dyspnea or haemorrhage are present then symptomatic lesions should, when possible, be resected which is curative. Different treatment modalities are available like intralesional and systemic corticosteroids, sclerosing agents, embolization, excision (as in our case), electrolysis, thermacautry and laser photocoagulation. Now a day's sclerosing therapy is employed due to its efficacy and ability to not destroy surrounding tissue. 
| Conclusion|| |
A rare case of hemangioma in the posterior third of tongue in a 10-year-old female which appeared localized well defined, reddish pink and lobulated mass with well-defined margins on intra-oral examination with typical features on ultrasonography and abnormally increased vascularity on color Doppler suggesting a vascular etiology. Further evaluation was done on contrast enhanced CT scan and MRI which confirms its vascular nature and diagnosed as a case of hemangioma.
