The term hamartoma (from the Greek word hamartia, meaning error) was first used by Eugen Albrecht in 1904, and later redefined by Willis,1 to designate nonneoplastic tumoral lesions resulting from the development of congenital defects and characterized by the existence of cells and mature tissues common to the place of origin. The lesions can be composed of multiple tissues derived from the 3 germ layers (ectoderm, mesoderm, and endoderm), but there is usually a predominance of only 1 of the 3. Localization in the nasopharynx is rare.2 The lesion in our case was diagnosed as anthrochoanal polyp because of the appearance, during oroscopy, of its surface and topography (Figure 1). However, during nasal endoscopy, the middle meatus of both nasal cavities was clear. During inspection of the nasopharynx, the origin of the lesion was discovered on the posterior surface of the nasopharynx, near the right pharyngeal recess.
