Abstract

Background

Odontogenic tumors (OTs) comprise a group of heterogeneous lesions ranging from hamartomatous or non-neoplastic tissue proliferation to benign or malignant neoplasms with metastatic potential. OTs are derived from epithelial, ectomesenchymal, and/or mesenchymal elements of tooth-forming (“odontogenic”) tissues, which show variable clinical and histopathological features.

Objective

Herein, the authors summarize the World Health Organization (WHO) 2022 classification of OTs and further highlight diagnostic tips and differential clues for the most common OTs.

Conclusion

OTs may not be commonly encountered in the daily practice of many pathologists. This makes their diagnosis challenging as there is little practice in understanding the features required for their classification. However, diagnosing the vast majority of these lesions is not difficult provided the following aspects are considered: 1) the general knowledge of tooth development; 2) a few key histological observations; 3) very basic knowledge of the clinical and especially the radiographic features with which they are associated.

Zusammenfassung

Hintergrund

Odontogene Tumoren (OT) umfassen eine Gruppe heterogener Läsionen, die von hamartomatösen oder nichtneoplastischen Gewebeproliferationen bis hin zu benignen oder malignen Neoplasmen mit Metastasierungspotenzial reichen. OT entstehen aus epithelialen, ektomesenchymalen und/oder mesenchymalen Elementen zahnbildender („odontogener“) Gewebe und weisen unterschiedliche klinische und histopathologische Merkmale auf.

Ziel der Arbeit

Die Autoren haben hier die Klassifikation der Weltgesundheitsorganisation (WHO) aus dem Jahr 2022 für OT zusammengefasst wie auch diagnostische Hinweise und Differenzialdiagnosen für OT aufgezeigt.

Schlussfolgerung

In der täglichen Praxis vieler Pathologen sind OT nicht unbedingt häufig anzutreffen. Dies macht ihre Diagnose schwierig, da es wenig Erfahrungen im Verständnis der für ihre Klassifizierung erforderlichen Merkmale gibt. Die Diagnose der überwiegenden Mehrheit dieser Läsionen ist jedoch nicht schwierig, wenn man Folgendes berücksichtigt: 1) das allgemeine Wissen über die Zahnentwicklung, 2) einige wichtige histologische Beobachtungen, 3) sehr grundlegende Kenntnisse der klinischen und insbesondere der röntgenologischen Merkmale, mit denen sie einhergehen.
