Surgical Resection and Immediate Reconstruction with a Bilayer Wound Collagen Matrix of a Rare Oral Angiosarcoma: A...

Angiosarcomas are malignant vascular tumors that commonly occur on the skin of the head and neck, breast, or scalp. Oral angiosarcoma is a rare tumor (0.0077% of all cancers in Europe), and regarding this atypical localization, no formal treatment trials have been conducted yet. We present a case of a 58-year-old female patient with a diagnosis of oral angiosarcoma. After tumor excision was performed by transoral surgical approach, immediate reconstruction of the intraoral surgical defects was made using Integra^® bilayer wound collagen matrix. A skin regeneration technique has previously been reported to provide good healing for defects of buccal resection, preventing postoperative cicatricial fibrosis.
