    Morphological similarities between B-cell and T-cell lymphomas can be misleading. Accurate classification of malignant lymphomas requires immunologic assessment beyond morphology alone.

    Area of Science:

    • Hematology
    • Oncology
    • Pathology

    Background:

    • Malignant lymphomas are a diverse group of lymphoid neoplasms.
    • Accurate classification is crucial for effective treatment and prognosis.
    • Morphological assessment is a cornerstone of lymphoma diagnosis.

    Purpose of the Study:

    • To describe cases of B-cell lymphoma with T-cell morphology.
    • To highlight the limitations of morphology in lymphoma classification.
    • To suggest these cases may represent a distinct clinicopathologic entity.

    Main Methods:

    • Morphological analysis of seven B-cell lymphoma cases.
    • Comparison with established lymphoma classifications.
    • Review of clinical and pathological features.

    Main Results:

    • Seven cases of B-cell lymphoma exhibited T-cell lymphoma-like morphology.
    • Observed morphologic subtypes included atypical poorly differentiated lymphocytic lymphoma (PDLL), Lennert's lymphoma, mixed lymphocytic-histiocytic lymphoma, and histiocytic lymphoma.
    • Significant variation in cell size and nuclear morphology was noted.

    Conclusions:

    • Morphological criteria alone are insufficient for accurate immunologic classification of lymphomas.
    • These challenging cases underscore the need for integrated diagnostic approaches.
    • Further investigation is warranted to define the distinct clinicopathologic nature of these lymphomas.
