During histological evaluation of the oral cavity of a 61-year-old West-European male body donor, we observed a bizarre epithelial formation at the border between gingiva and oral mucosa, which most likely was an orobasal organ (of Ackerknecht). Although the orobasal organ probably does not have a functional significance, it is of clinical interest, because it must not be confused with a pathological condition like oral precancerous lesions or oral cancer.
