Hamartomadescribes a lesion composed of disorganized but mature specialized cells that are indigenous to the particular site.1Hamartomas are thought to arise from anomalous development and, unlike neoplastic lesions, are incapable of unimpeded growth. They commonly originate in the lungs, kidneys, and intestines but are uncommon elsewhere in the body and are seldom found in the nasal cavity and paranasal sinuses.2
