Cavernous hemangioma is the most common orbital tumor in adult. There is lot of literatures for clinicopathological features of this tumor. These tumors had been studied for the model of angiogenesis in many of the experimental setups. We present a case of 34-year-old male with this tumor in the left eye with computerized tomography evidence. Postsurgical laboratory findings gave interesting evidence of tumor angiogenesis with tumor endothelial cells and sprouting of the small vessels endothelial cells. Podosome rosette could be conceptualized from the characteristic patterns seen in the tumor...

Infantile hemangiomas are the most common vascular neoplasm that present in infancy, with more than half affecting the head and neck region. Periocularly, hemangiomas may be complicated by visual loss through induction of strabismal, deprivational, or anisometropic astigmatism. We report a case of a 5-year-old girl who presented with orbital hemangioma with potential risk of visual loss who had excellent response to propranolol.

BACKGROUND AND AIM: Beta-adrenergic antagonists have been established as first line treatment in the medical management of hypertension, acute coronary syndrome and other cardiovascular diseases, as well as for the prevention of initial episodes of gastrointestinal bleeding in patients with cirrhosis and esophageal varices, glaucoma, and have recently become the main form of treatment of infantile hemangiomas. The aim of the present study is to calculate for 14 beta-blockers several quantum chemical descriptors in order to interpret various molecular properties such as electronic structure, conformation, reactivity, in the interest of determining how such descriptors could have an impact on our understanding of the experimental observations and describing various aspects of chemical binding of beta-blockers in terms of these descriptors...

Orbito-palpebral vascular pathology represents 10% of all the diseases of this area. The lesion may be discovered during a brain CT scan or MRI, or because it causes clinical symptoms such as orbital mass, visual or oculomotor alteration, pain, proptosis, or acute bleeding due to a complication of the lesion (hemorrhage, thrombosis). We present these lesions using an anatomical, clinical, imaging and therapeutic approach. We distinguish four different entities. Vascular tumors have common imaging characteristics (hypersignal on T2 sequence, contrast enhancement, abnormal vascularization well depicted with ultrasound and Doppler, and possible bleeding)...

Diseases of the orbit can be categorized in many ways, but in this chapter we shall group them according to etiology. Inflammatory diseases of the orbits may be infectious or noninfectious. Of the infections, orbital cellulitis is the most common and typically arises as a complication of acute sinusitis. Of the noninfectious, inflammatory conditions, thyroid orbitopathy is the most common and results in enlargement of the extraocular muscles and proliferation of the orbital fat. Idiopathic orbital inflammatory syndrome is another cause of inflammation in the orbit, which may mimic thyroid orbitopathy or even neoplasm, but typically presents with pain...

A primary intraosseous hemangioma (IOH) of the orbital bone is extremely rare. The preferred method of treatment for IOH is total surgical excision with reconstruction. Herein, the authors describe a patient with an orbital roof IOH and the unexpected complications of ptosis and deteriorated exophthalmos. These findings showed that the total surgical excision and subsequent reconstruction provided adequate decompression and prevented further ocular complications from the orbital wall defect.

With the use and efficacy of the vascularized nasoseptal flap, its indications are also expanding. Due to its relative ease of harvesting and no significant impairment in the long-term sinonasal quality of life, the flap has been used for a number of other purposes apart from its originally proposed use in reconstruction of the anterior cranial fossa, sella, and the clivus. Its use may negate the need of another incision to obtain fat or fascia. The authors describe the case of a 47-year-old lady who underwent endoscopic excision of a medially placed orbital intraconal hemangioma who presented to us with very poor vision in the left eye...

OBJECTIVE Cavernous sinus hemangiomas (CSHs) are rare vascular tumors. A direct microsurgical approach usually results in massive hemorrhage and incomplete tumor resection. Although stereotactic radiosurgery (SRS) has emerged as a therapeutic alternative to microsurgery, outcome studies are few. Authors of the present study evaluated the role of SRS for CSH. METHODS An international multicenter study was conducted to review outcome data in 31 patients with CSH. Eleven patients had initial microsurgery before SRS, and the other 20 patients (64...

Infantile hemangiomas (IHs) are common, benign vascular tumors of infancy, with more than half affecting the head and neck region. IHs involving the lips and oral cavity can often present to the oral surgeon and the pedodontist. Till date, several doubts exist among clinicians regarding the use of propranolol to treat infantile hemangiomas in neonates and small infants, appropriate dose, treatment duration, side effects, response, and long-term follow-up. We present a 2-month-old male infant with extensive hemangioma involving the face, orbit, buccal mucosa and palate with feeding difficulties, and risk of life-threatening complications such as airway compromise, aspiration, and visual loss which showed excellent response with high-dose propranolol and had no side effects...

Pain is among the most common reasons for patient visits to healthcare providers, especially to dental practitioners. This case illustrates the obligation of the general dentist and specialist to recognize facial pain disorders of nonodontogenic origin, and outlines a paradigm for treatment of this unusual case. A 59-year-old man presented with chronic, progressive right periorbital pain since 2006, of 7 years duration. The initial diagnosis was a fracture of the right outer rim of the orbit secondary to trauma...

OBJECTIVE: The medial rectus muscle (MRM) is the medial boundary to the intraconal space of the orbit, and retraction of the MRM is oftentimes necessary for endoscopic removal of intraconal tumors, e.g., orbital hemangioma. We evaluated each of the reported methods of MRM retraction for endoscopic orbital surgery and quantified the degree of intraconal exposure conferred by each method. METHODS: Eight orbits from four cadaver heads were dissected. In each orbit, medial orbital decompression was performed and the MRM was retracted by using four previously described techniques: (1) external MRM retraction at the globe insertion point by using vessel loop (external group), (2) transseptal MRM retraction by using vessel loop (transseptal group), (3) transchoanal retraction of the MRM by using vessel loop (choanal group), and (4) transseptal four-handed technique by using double ball retraction by a second surgeon (transseptal double ball group)...

BACKGROUND: Granular cell tumors are rare neoplasms which can occur in any part of the body. Granular cell tumors of the orbit account for only 3 % of all granular cell tumor cases. Computed tomography and magnetic resonance imaging of the orbit have proven useful for diagnosing orbital tumors. However, the rarity of intraorbital granular cell tumors poses a significant diagnostic challenge for both clinicians and radiologists. CASE PRESENTATION: We report a case of a 37-year-old Chinese woman with a rare intraocular granular cell tumor of her right eye presenting with diplopia, proptosis, and restriction of ocular movement...

Orbital tumors are a rather frequent pathology. Their diagnosis and treatment may be difficult. They can be benign or malignant. All the tissues of the orbit can give rise to a tumor, resulting in their large number. Among the benign tumors, we have meningiomas and cavernous hemangiomas, and for the malignant tumors, lymphomas, metastasis, ENT tumors and lacrimal gland tumors in the adult. Usually the signs are nonspecific, with proptosis, oculomotor disturbance, inflammatory signs, pain and sometimes a mass...

Spindle cell hemangioma (SCH) is an uncommon tumor that usually presents as subcutaneous or deep dermal nodule affecting the extremities and is typically <2 cm in size. A few cases have been reported in the head and neck region. To the best of the authors' knowledge, there are no previous reports of SCH occurring in the orbit in the English literature. We, therefore, report the case of a large SCH involving the right orbit of a healthy 9-year-old Nigerian girl.

Capillary hemangioma is one the most common tumors of eyelid and orbit reported in pediatric age group. Oral propranolol therapy is latest addition to the armamentarium of treatment options available to ophthalmologists in treating capillary hemangiomas. We report the successful response to propranolol therapy to a 5-year-old child with capillary hemangioma involving lids, orbit, and the paranasal sinuses. A long-term follow-up is necessary for the prognostic efficacy of the therapy.

UNLABELLED: Vascular lesions have been classified in two broad categories, hemangiomas and malformations. Encapsulated vascular lesions have not been reported in the oral cavity, but they were described in other sites, mainly in the orbit. Herein, we present a case of an oral encapsulated vascular lesion located in the right buccal mucosa of a 69-year-old male, including histological and immunohistochemical description and a literature review. KEY WORDS: Buccal mucosa, hemangioma, vascular malformation, oral cavity...
