    Fifty percent of patients with solitary, painless enlarged lymph nodes showing reactive hyperplasia with giant follicles were misdiagnosed as lymphoma. This condition, often affecting salivary glands, requires careful histologic differential diagnosis.

    Area of Science:

    • Pathology
    • Oncology
    • Histology

    Background:

    • Solitary, painless enlarged lymph nodes can present diagnostic challenges.
    • Reactive hyperplasia with giant follicles is a potential mimic of lymphoid malignancies.

    Purpose of the Study:

    • To describe the clinical and histological features of reactive hyperplasia with giant follicles.
    • To highlight the diagnostic pitfalls and differential diagnosis of this condition, particularly its misdiagnosis as lymphoma.

    Main Methods:

    • Retrospective review of 22 cases with solitary, painless enlarged lymph nodes.
    • Clinical data and histopathological findings were analyzed.
    • Follow-up data was collected to assess recurrence.

    Main Results:

    Related Experiment Videos

    • Eleven out of 22 cases (50%) were initially misdiagnosed as lymphoma.
    • Parotid or submandibular nodes were most commonly affected.
    • No recurrences were observed during follow-up periods ranging from 6 months to 15 years.

    Conclusions:

    • Reactive hyperplasia with giant follicles can be mistaken for lymphoma, necessitating thorough histopathological evaluation.
    • Understanding the characteristic microscopic features is crucial for accurate diagnosis and avoiding unnecessary treatment.
    • This benign condition has a favorable prognosis with no observed recurrences.
