Intraosseous hemangioma is a benign vascular tumor of the bone. The most common site of this tumor is the vertebral body, followed by calvarial bones. Intraosseous hemangioma of the nasal cavity is extremely rare. This lesion had en bloc been resected through the endoscopic approach without preoperative embolization, significant intraoperative bleeding, and postoperative events. We report a rare case of intraosseous hemangioma of the nasal cavity with distinctive radiologic findings. Clinicians should be well familiar with the radiologic findings and clinical features of this tumor, which would be helpful in making a correct diagnosis and management plan.
Rhabdomyomatous mesenchymal hamartoma is a rare congenital tumor and usually occurring in the head and neck. Characteristically, this tumor is composed of various mesenchymal elements such as adipose tissue, blood vessels, collagen fibers, elastic fibers, and peripheral nerves in random orientation. We present a 7-year-old boy with an intranasal mass developed after the trauma and who had a diagnosis of rhabdomyomatous mesenchymal hamartoma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
