Overview
Intraductal papillomatosis, as observed in green turtles (Chelonia mydas), refers to the development of fibropapillomas characterized by benign tumor growths primarily affecting external, oral, and internal tissues, often leading to significant morbidity and mortality 1.Diagnosis
Clinical Signs: Presence of external tumors, predominantly on the front of the turtle; oral tumors, especially involving the glottis; and internal tumors in organs like the lung, kidney, and heart 1.
Tumor Grading: Utilize a standardized tumor severity score (1-3) based on tumor burden and size 1.
Histopathological Evaluation: Light microscopy to confirm fibropapillary nature and exclude malignant transformation 1.Management
Supportive Care: Focus on maintaining hydration, nutrition, and respiratory support, particularly in cases with glottal obstruction 1.
Surgical Intervention: Removal of large, obstructive tumors, especially those affecting respiration 1.
Antimicrobial Therapy: Not explicitly detailed in the abstract; empirical use may be considered based on secondary infections 1.Special Populations
Juveniles: Higher prevalence of fibropapillomatosis observed in juvenile turtles compared to subadults and adults 1.Key Recommendations
Standardize Tumor Assessment: Implement a standardized tumor severity scoring system to monitor disease progression and guide treatment decisions (Evidence: Moderate 1).
Prioritize Respiratory Support: Address glottal tumors promptly to prevent respiratory compromise (Evidence: Moderate 1).
Consider Surgical Removal for Obstructive Tumors: Indicative for large tumors causing significant functional impairment (Evidence: Expert opinion 1).References
