    Three related teddy bear hamsters developed hyperadrenocorticism, a condition causing skin issues like hair loss and darkening. Treatment with metyrapone and o,p-DDD showed success in one case, with tumors found in two hamsters.

    Area of Science:

    • Veterinary Medicine
    • Endocrinology
    • Small Animal Internal Medicine

    Background:

    • Hyperadrenocorticism is a complex endocrine disorder.
    • Teddy bear hamsters can be affected by hormonal imbalances.
    • Skin changes like alopecia and hyperpigmentation are key indicators.

    Purpose of the Study:

    • To diagnose and investigate hyperadrenocorticism in a family of teddy bear hamsters.
    • To evaluate treatment options for affected hamsters.
    • To determine the underlying causes of the disease in this population.

    Main Methods:

    • Clinical diagnosis of hyperadrenocorticism based on presenting signs.
    • Treatment attempts using metyrapone and o,p'-DDD.
    • Necropsy and histopathological examination for definitive diagnosis.

    Main Results:

    • Three related hamsters were diagnosed with hyperadrenocorticism.
    • Successful treatment was achieved in one hamster.
    • Histopathology revealed a pituitary chromophobe adenoma in one and an adrenocortical adenocarcinoma in another.

    Conclusions:

    • Hyperadrenocorticism can affect related teddy bear hamsters.
    • Tumors (pituitary adenoma, adrenocortical adenocarcinoma) are potential causes.
    • Further investigation is needed for cases with undetermined origin.
