Pindborg

Pindborg is a Danish surname. It is most widely recognized in medical and dental literature because of Jens Jørgen Pindborg, a Danish dental pathologist who described a rare odontogenic tumor now commonly referred to as the Pindborg tumor. The tumor's formal designation is calcifying epithelial odontogenic tumor (CEOT).

CEOT is a rare benign odontogenic tumor of epithelial origin. It most often affects adults and typically involves the jaw, with a preference for the posterior mandible. Clinically, CEOT may present as a slow-growing, painless swelling and, less commonly, as cortical expansion. Radiographically, it can appear as a unilocular or multilocular radiolucent lesion containing scattered radiopacities from calcifications.

Histologically, CEOT is characterized by aggregates of polygonal epithelial cells, sometimes showing nuclear pleomorphism, along with amyloid-like extracellular material that tends to calcify into concentric formations known as Liesegang rings. The lesion is generally treated with surgical excision, ranging from curettage to segmental resection depending on size and location. Recurrence is uncommon but has been reported in a minority of cases.

In summary, Pindborg denotes a Danish surname associated with Jens Jørgen Pindborg, and the name is also linked to the calcifying epithelial odontogenic tumor, a rare benign jaw tumor named in his honor.
