    Summary

    Bilateral malignant adrenal polyadenomas are rare, often involving double tumors or metastasis. This case shows unique adrenal carcinogenesis with varying histological features and hormonal dependence, highlighting therapeutic implications.

    Area of Science:

    • Endocrinology
    • Oncology
    • Pathology

    Background:

    • Bilateral malignant adrenal polyadenomas are uncommon, presenting as either primary bilateral tumors or contralateral metastasis.
    • Understanding the progression of adrenal tumors is crucial for effective treatment strategies.

    Observation:

    • A rare case of bilateral malignant adrenal polyadenomas exhibited fluctuating hormonal activity.
    • The tumor demonstrated periods of ACTH (adrenocorticotropic hormone) stimulation with partial autonomy and periods of autonomous function with central suppression.

    Findings:

    • Pathological examination revealed a unique spectrum of histological changes, including atrophy, hyperplasia, benign adenoma, and carcinoma.
    • These findings suggest a stepwise adrenal carcinogenesis process, potentially initiated by ACTH stimulation.

    Implications:

    • The observed physiopathological mechanism suggests ACTH may drive initial hyperplasia, progressing to autonomous tumors.
    • Post-surgical suppression of endogenous ACTH with cortisol or cortisone therapy is recommended to prevent recurrence by mitigating corticotropin stimulation of residual malignant cells.
