Reappraisal of tubulopapillary hidradenoma-like tumor of the mandible: Suggested change in nomenclature to reflect tumor origin.

Several cases of intraosseous mandibular tumors have been reported under the name "tubulopapillary hidradenoma-like tumor of the mandible (TPHLTM)." However, the intraosseous occurrence of sweat gland tumors needs to be reappraised. The aim of this review was to propose a new name for these tumors to reflect the possible tumor origin. In view of the incidence and the tissue of origin, TPHLTM is more likely to be a salivary gland tumor than a sweat gland tumor. Among salivary gland tumors, a recently described salivary neoplasm called "sialadenoma papilliferum-like intraductal papillary tumor (SP-IPT)" seems to be histologically and genetically identical to tubulopapillary hidradenoma. Therefore, we proposed that the term TPHLTM be replaced by "SP-IPT of the mandible," which better explains its origin and could help in clarifying the nature of SP-IPT.Copyright © 2022 Elsevier Inc.
