Zusammenfassung

Gegenstand und Ziel: Odontogene Tumoren kommen bei Hund und Katze, wie auch bei den übrigen Haustierarten und beim Menschen, selten vor und können schwer zu diagnostizieren sein. In der vorliegenden Studie wurde eine größere Anzahl odontogener Tumoren von Hund und Katze histopathologisch untersucht und klassifiziert mit dem Ziel, eine verlässliche Grundlage für die Diagnostik dieser Tumoren zu schaffen. Material und Methoden: In der retrospektiven Studie wurden von 1390 kaninen und 317 felinen oralen Tumoren aus den Jahren 1977 bis 2007 die odontogenen Neoplasien selektiert, histopathologisch charakterisiert und anhand der aktuellen human-und veterinärmedizinischen WHO-(World Health Organization) Klassifikationen odontogener Tumoren (2005 bzw. 2003) eingeteilt. Ergebnisse: 18% (n = 250) der kaninen und 3,2% (n = 10) der felinen oralen Tumoren erwiesen sich als odontogen. Sie ließen sich in benigne (epitheliale, epitheliale und ektomesenchymale sowie ektomesenchymale) und maligne odontogene Tumoren (Karzinome und Sarkome) mit insgesamt 12 Entitäten unterteilen. Sowohl beim Hund wie auch bei der Katze war das odontogene Fibrom der am häufigsten diagnostizierte Tumor (n = 167 bzw. n = 4). An zweiter Stelle folgte beim Hund das Ameloblastom (n = 74), bei der Katze das ameloblastische Fibrom (n = 2). Vier der 12 Entitäten konnten anhand beider, sieben lediglich anhand der human-, zwei lediglich anhand der veterinärmedizinischen WHO-Klassifikation klassifiziert werden. Schlussfolgerung und klinische Relevanz: Die prognostische Bewertung von Tumorerkrankungen ist von größter klinischer Relevanz und setzt eine eindeutige Diagnose voraus. Insbesondere bei seltenen und histomorphologisch komplexen odontogenen Tumoren genügt die aktuelle veterinärmedizinische WHO-Klassifikation diesem Anspruch nicht und bedarf einer Überarbeitung und Erweiterung. Wirkungsvoller im Einsatz erwies sich die humanmedizinische WHO-Klassifikation.

Summary

Objective: Odontogenic tumours in the dog and cat, as well as in other domestic animals and in man occur rarely and can be difficult to diagnose. In the present study a great number of canine and feline odontogenic tumours were investigated histopathologically and classified to provide an appropriate basis for the evaluation of these tumours. Material and methods: In a retrospective study of a total of 1390 canine and 317 feline oral tumours from the years 1977 to 2007, the tumours of odontogenic origin were selected, characterized histopathologically and classified according to the current human WHO-classification of odontogenic tumours (2005) and the current veterinary WHO-classification of odontogenic tumours (2003). Results: 18% (n = 250) of the canine and 3.2% (n = 10) of the feline oral tumours proved to be of odontogenic origin. They could be divided into benign (epithelial, epithelial and ectomesenchymal, ectomesenchymal) and malignant (carcinomas and sarcomas) odontogenic tumours with a total of 12 different entities. The odontogenic fibroma was the most common canine (n = 167) and feline (n = 4) odontogenic tumour. The second most common odontogenic tumour for canines was ameloblastoma (n = 74) and that for felines was ameloblastic fibroma (n = 2). Four of the 12 entities could be classified according to both WHO-classifications of odontogenic tumours. Seven and two of the 12 entities could only be classified according to the current human WHO-classification and veterinary WHO-classification, respectively. Conclusion and clinical relevance: The prognostic evaluation of tumours is of the greatest clinical relevance and calls for an absolutely certain diagnosis. Particularly in the case of the rare and histomorphologically complex odontogenic tumours the current veterinary WHO-classification does not meet this requirement and needs to be revised and extended. The human WHO-classification proved to be more efficient when compared to the veterinary one.
