Rhabdomyomatous mesenchymal hamartoma of nasal vestibule

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.
