Leisegang rings are associated with which type of lesion?

Leisegang rings are associated with Pindborg tumor, also known as an odontogenic tumor that resembles an ameloblastoma but often has a distinct histological appearance. These rings represent concentric layers of epithelial cells or calcified material found in specific lesions, and their presence is a key histological feature of the Pindborg tumor.

In this context, Leisegang rings reflect the unique biological behavior of the Pindborg tumor, which can sometimes show calcification patterns that are not only indicative of its histological characteristics but also its odontogenic nature. The Pindborg tumor typically occurs in the mandible and has a potential for aggressive behavior, but it is less common than other odontogenic lesions such as ameloblastomas and keratocysts.

Understanding the morphology of oral lesions and their histological features helps in diagnosing and differentiating tumors and cysts within the jaw. The presence of Leisegang rings specifically aids in identifying the Pindborg tumor, making this association significant in oral pathology.
