    Biochemical evidence diagnosed primary hyperparathyroidism and multiple myeloma in a patient lacking roentgenographic signs. Surgical removal of a parathyroid adenoma resolved hyperparathyroidism.

    Area of Science:

    • Endocrinology
    • Hematology
    • Oncology

    Background:

    • Primary hyperparathyroidism and multiple myeloma are distinct conditions.
    • Co-occurrence presents diagnostic challenges, especially without clear radiographic findings.

    Observation:

    • A patient presented with biochemical markers for both primary hyperparathyroidism (hypercalcemia, elevated parathyroid hormone) and multiple myeloma (elevated IgA, monoclonal spike, bone marrow plasmacytosis).
    • Initial presentation lacked roentgenographic evidence of either disease.

    Findings:

    • Serum and urine immunoelectrophoresis revealed abnormal IgA and lambda arcs, confirming monoclonal gammopathy.
    • Computed tomography identified a parathyroid adenoma in the neck.
    • Surgical resection of the parathyroid adenoma successfully treated the hyperparathyroidism.

    Implications:

    • Highlights the importance of biochemical diagnostics in complex cases.
    • Underscores the need for thorough evaluation when clinical or radiographic findings are atypical.
    • Demonstrates successful management of co-existing endocrine and hematologic malignancies.
