congenital disorder characterized by cutaneous hemangiomas, hypertrophy of bone and soft tissue, varicose veins, and clinically significant arteriovenous malformation (AVM) (1, 2, 3). AVMs associated with KTWS are located in the extremities, visceral organs, or spinal canal (1, 3). Most AVMs in the extremities are intramuscular or cutaneous. There is a paucity of data on AVMs in the suprapatell...

Facial vascular malformations can cause dental emergencies that result in fatal or life-threatening and disfiguring situations. A knowledge of vascular malformation, its clinical presentation and its complications can prevent iatrogenically related accidents and minimize potential spontaneous crisis for the patient in the dental clinic. A vascular malformation (VM) is a morphogenetic abnormalit...

While infantile hemangiomas are a very common lesion seen in infants and young children, congenital hemangiomas are much more rare and have been only recently described. Two types of congenital hemangiomas exist: rapidly involuting congenital hemangiomas and noninvoluting congenital hemangiomas. The goal of this article is to describe rapidly involuting and noninvoluting congenital hemangiomas ...

The retrospective study investigated accuracy of quantitative evaluation of T1-weighted imaging (T1WI) with and without fat suppression (FS), chemical-shift, diffusion-weighted imaging (DWI) and enhanced imaging at 3.0 T MRI for distinguishing spinal hemangiomas from metastases. 27 patients with 33 spinal hemangiomas (15 atypical hemangiomas) and 26 patients with 71 metastases were recruited. T...

RATIONALE Hemangiomas are benign tumors characterized by an abnormal proliferation of blood vessels, most often occur in the skin and subcutaneous tissue, intramuscular hemangioma, a distinctive type of hemangioma within the skeletal muscle, account for <1% of all hemangiomas, temporalis muscle is a very uncommon site, cavernous hemangioma of the temporalis muscle with prominent formation of ph...

Hemangiomas are defined as soft tissue lesions in the maxillofacial or oral region. Hemangiomas of salivary glands constitute 30% of the non-epithelial tumors in major salivary glands.  Benign tumors in salivary glands are located 85% in parotid gland and 13% in submandibular gland. We present a case of submandibular hemangioma in an infant patient that had some complications and a challenging ...

OBJECTIVE To describe the clinical presentation and risk of PHACE syndrome in infants with large facial hemangiomas and concomitant airway hemangiomas. DESIGN The study involved a case series of infants with cutaneous hemangiomas and airway hemangiomas extracted from a prospective multicenter cohort study. Data regarding clinical features, diagnosis, treatment, and clinical course were obtain...

Intramuscular hemangioma (IMH) is a rare vascular disease involving skeletal muscle, comprising only 0.8% of hemangiomas. About 10% to 15% of IMHs occur in the head and neck region, mostly involving the masseter muscle. IMH occurs mostly in childhood, but is often not found until unexpected enlargement, pain, or cosmetic asymmetry occurs in adulthood. Several non-surgical treatments including c...

Laryngeal hemangiomas are relatively rare. Laryngeal hemangiomas occur in two main forms--infantile and adult laryngeal hemangiomas. While infantile hemangiomas are usually found to occur in the subglottis, adult hemangiomas occur commonly in the supraglottic regions of the larynx. Laryngeal hemangioma with cavernous features isolated to the free edge of the vocal fold is a very rare clinical f...
