Auricular Arteriovenous Malformation With Macrotia Treated With Transcatheter Arterial Embolization, Polidocanol Foam Sclerotherapy and Subsequent Otoplasty Following Resection.

Auricular arteriovenous malformation (AVM) occasionally accompanies macrotia. Here, the authors report a case of AVM with macrotia that was treated with transcatheter arterial embolization, percutaneous sclerotherapy, and subsequent otoplasty following partial resection. A 46-year-old man presented with Schobinger stage III AVM.

Ulcerated Infantile Hemangioma of the Hard Palate: Diagnostic Treatment With Oral Propranolol.

Infantile hemangiomas arising in the palate are rare. The authors describe a case of ulcerated infantile hemangioma of the hard palate with feeding difficulty. To our knowledge, this is the first reported case of immunohistochemically diagnosed palatal infantile hemangioma successfully treated using oral propranolol.

NEDD4 Is Involved in Inflammation Development during Keloid Formation.

Keloids mark a chronic inflammatory disease characterized by a fibroproliferative disorder of the skin. A genome-wide association study showed that single-nucleotide polymorphism rs8032158 in the neural precursor cell-expressed NEDD4 gene, which has six protein-coding transcript variants (TVs), is genetically linked to keloids. Here, we show that the high frequency of risk allele C in rs8032158 in keloid patients is associated with a selectively higher expression of TV3 of NEDD4 to activate the NF-κB pathway.

Transarterial Embolization and Transmucosal Sclerotherapy That Led to Successful Deliveries in a Patient With Symptomatic Arteriovenous Malformation of the Tongue.

Patients with arteriovenous malformations (AVMs) are at risk of significant hemorrhage and AVMs are especially difficult to manage in those desiring future pregnancy. Few patients with successful deliveries have been previously reported.The authors report an unusual case of AVM of the tongue in a pregnant woman who presented with massive pulsatile bleeding from a ruptured artery in the tongue in late gestation, this was thought to be caused by the changes in hormonal balance and the increase in cardiac output.

A case of combined soft tissue and intraosseous venous malformation of the thumb treated with sclerotherapy using a bone marrow aspiration needle.

Vascular malformations of bone are complex lesions that can cause deformity and pain. A combined soft tissue and intraosseous venous malformation of the left thumb in a girl was treated with two sessions of ethanol sclerotherapy using a bone marrow aspiration needle under fluoroscopic guidance.
