Cutaneous squamous cell carcinoma and hypercalcemia.

D D Picascia, W A Caro

    Journal of the American Academy of Dermatology
    |August 1, 1987
    PubMed
    Summary

    A rare case of hypercalcemia (elevated serum calcium) associated with localized skin squamous cell carcinoma in an elderly man was successfully treated by surgical tumor removal. This highlights a potential paraneoplastic syndrome.

    Area of Science:

    • Oncology
    • Endocrinology
    • Dermatology

    Background:

    • Squamous cell carcinoma (SCC) is a common skin cancer.
    • Hypercalcemia is a serious condition often linked to malignancy but rarely to localized skin SCC.
    • Paraneoplastic syndromes can manifest with diverse systemic symptoms.

    Observation:

    • An elderly male patient presented with a large chest wall SCC and severe confusion.
    • Laboratory tests revealed significantly elevated serum calcium levels (hypercalcemia).
    • The patient's confusion and hypercalcemia resolved after surgical excision of the tumor.

    Findings:

    • This case demonstrates a rare occurrence of hypercalcemia associated with localized cutaneous SCC.
    • The resolution of hypercalcemia post-surgery suggests a paraneoplastic etiology, possibly due to tumor-secreted factors.
    • Transforming growth factor or other humoral substances are hypothesized as the cause.

    Implications:

    • Highlights the importance of investigating hypercalcemia in patients with SCC, even when localized.
    • Suggests that localized skin SCC can potentially cause paraneoplastic hypercalcemia.
    • Further research into the humoral factors secreted by SCC may elucidate this rare paraneoplastic syndrome.
