Ameloblastic odontoma in a rat.

T A Barbolt, J C Bhandari

    Laboratory Animal Science
    |December 1, 1983
    PubMed
    Summary

    A rare ameloblastic odontoma, a benign tumor, was discovered in an aged Fischer 344 rat. This finding highlights the importance of veterinary pathology in diagnosing spontaneous neoplasms.

    Area of Science:

    • Veterinary Pathology
    • Comparative Oncology
    • Oral Neoplasia

    Background:

    • Spontaneous neoplasms in aging animal models offer insights into tumor development.
    • Fischer 344 rats are a common model for aging and cancer research.
    • Odontomas are rare tumors of odontogenic origin.

    Observation:

    • A spontaneous ameloblastic odontoma was identified in an 86-week-old male Fischer 344 rat.
    • The lesion presented unique radiographic features.
    • Histopathological examination was crucial for definitive diagnosis.

    Findings:

    • Radiographic and histopathologic analyses confirmed the lesion as an ameloblastic odontoma.
    • The tumor was definitively classified as a true benign neoplasm.
    • This represents a rare occurrence of this specific tumor type in this model.

    Implications:

    • This case contributes to the understanding of odontogenic tumors in animal models.
    • Accurate diagnosis of spontaneous neoplasms is vital for research integrity.
    • Further studies may explore the specific etiology and behavior of ameloblastic odontomas in rats.
