DiGeorge syndrome associated with multiple squamous cell carcinomas

H H Tewfik, J J Ptacek, C J Krause

    Archives of Otolaryngology (Chicago, Ill. : 1960)
    |February 1, 1977

    Summary

    DiGeorge syndrome, a condition with impaired immunity due to thymus absence, is linked to multiple squamous cell carcinomas. This case highlights the critical role of cell-mediated immunity in cancer prevention.

    Area of Science:

    • Immunology
    • Oncology
    • Genetics

    Background:

    • Immune mechanisms are increasingly recognized as critical factors in cancer development and progression.
    • DiGeorge syndrome is a congenital disorder characterized by thymus aplasia, leading to severe T-cell immunodeficiency.

    Observation:

    • A 42-year-old male patient with DiGeorge syndrome presented with multiple squamous cell carcinomas in the upper respiratory tract.
    • The patient exhibited a complete absence of cell-mediated immunity, characteristic of DiGeorge syndrome.

    Findings:

    • The case demonstrates a strong association between DiGeorge syndrome, impaired cell-mediated immunity, and the development of multiple squamous cell carcinomas.
    • Lymph nodes showed plasma cells and germinal centers, but a significant paucity of lymphocytes in paracortical areas, confirming T-cell deficiency.

    Implications:

    • This case underscores the importance of cell-mediated immunity in preventing cancer, particularly squamous cell carcinomas.
    • Understanding the interplay between immune defects and oncogenesis in conditions like DiGeorge syndrome may inform novel cancer surveillance and therapeutic strategies.
