Neuroepithelial Structures Similar to Juxtaoral Organ of Chievitz Present in the Mandibular Torus of a 41-year-old Man

The Juxtaoral organ of Chievitz (JOOC) is a normal neuroepithelial structure that is located in the pterygomandibular space. Neuroepithelial structures resembling those seen in the Juxtaoral organ of Chievitz in other locations are diagnostically challenging and can be potentially misdiagnosed as squamous cell carcinoma. Here, we report the first case of such structures presenting on the right lingual surface of the mandible of a 41-year-old man with torus mandibularis. Awareness of the possibility that neuroepithelial structures similar to the JOOC may be found in mandibular tori will prevent unwarranted costly diagnostic procedures and unnecessary surgical interventions.
