    Area of Science:

    • Hematology
    • Oncology
    • Immunology

    Background:

    • T-cell lymphomas are a heterogeneous group of lymphoid malignancies.
    • Accurate classification is crucial for prognosis and treatment.

    Observation:

    • A unique case of T-lymphoma in a 67-year-old male is presented.
    • Clinical spread involved lymph nodes, liver, lungs, and bone marrow, sparing skin, spleen, and thymus.
    • Morphologically, neoplastic cells were large with hypersegmented nuclei, coarse chromatin, and prominent nucleoli.

    Findings:

    • Cytochemical staining for acid phosphatase and esterase was negative for T-cell patterns.
    • Neoplastic lymphocytes showed strong binding with sheep erythrocytes.
    • Morphological features were distinct from other non-Hodgkin's lymphomas.

    Implications:

    • This case expands the spectrum of T-lymphoma presentations.
    • Distinguishing this lymphoma from other peripheral T-cell lymphomas is critical.
    • Further research is needed to clarify the specific subtype and its clinical behavior.
