    This study details a unique lung cancer case producing multiple hormones. The anaplastic small cell carcinoma secreted both APUD series hormones and placental hormones, leading to gynecomastia.

    Area of Science:

    • Endocrinology
    • Oncology
    • Pathology

    Background:

    • Gynecomastia can be associated with lung cancer.
    • Endocrine dysfunction in cancer patients requires thorough investigation.

    Observation:

    • A patient with lung cancer presented with gynecomastia.
    • Hormone assays revealed elevated human chorionic gonadotropin (hCG) and mild hyperadrenocorticism.

    Findings:

    • Postmortem examination identified anaplastic small cell lung carcinoma with chorioepithelioma features.
    • Tumor tissues contained adrenocorticotropic hormone (ACTH), beta-melanocyte stimulating hormone (beta-MSH), calcitonin, gastrin, hCG, hCG-alpha, hCG-beta, and human chorionic somatomammotropin (hCS).
    • This represents a rare instance of a tumor producing both amine precursor uptake and decarboxylation (APUD) series hormones and placental hormones.

    Implications:

    • This case highlights the potential for lung cancer to produce a wide array of hormones.
    • Understanding multiple hormone production in tumors is crucial for diagnosis and treatment.
    • Further research into the mechanisms of ectopic hormone production in lung cancer is warranted.
