Abstract

Hamartom or hamartoma is a tumor-looking tissue malformation that consist the mixture of normally forming elements of thedeveloped organ and an abnormal elements. Although this tissue’s appearance normal but functions is different. Mostly they are benign tumors. Hamartoma, unlike neoplasms, have not continuous growth ability, result of this limitting themselves to proliferation. Hamartoma tend to originate from lung, liver, kidney, intestinal system. However, upper respiratory tract is a uncommon location. Nasal hamartomas (NH) are rarely seen but widely originate from nasal septum or nasal cavity. Histologically, the common sub-type is Respiratory Epithelial Adenomatoid hamartoma (REAH), which is characterized by the presence of glandular elements originating from the respiratory epithelium, not the serömüköz gland. Thisproperty separates themfromthe inflammatory polyps, that’sglandular elements originate from serömüköz glands. Hamartomas etiopathogenesis is unknown. This case present a REAH determined patient, and reviewing the literature of this type of tumor that originating from the nasal cavity.
