I report a 42-year-old female with a pendunculated tonsil. A pedunculated tonsil usually arises from the palatine tonsil, rarely from epipharyngeal tissue. The tumor-like mass in this patient had originated from the juxta-orifice of the left eustachian tube. After surgical resection, histological examination revealed that it was composed of atrophic lymphoid follicles and was covered by a squamous epithelium with an underlying rim of fibrous tissue, without evidence of malignancy.
Key words : pedunculated tonsil, eustachian tube
