    This case report details an unusual, aggressive cutaneous immunoblastic T-cell lymphoma in a 69-year-old male. Despite extensive treatment, the high-grade malignant lymphoma progressed, leading to systemic involvement and death.

    Area of Science:

    • Oncology
    • Dermatology
    • Hematology

    Background:

    • Malignant lymphomas can present with diverse clinical manifestations.
    • Cutaneous lymphomas require precise diagnosis for effective management.
    • Distinguishing high-grade from low-grade lymphomas is critical for prognosis.

    Observation:

    • A 69-year-old male presented with follicular papules, erythematous patches, cutaneous tumors, lymphadenopathy, and severe pruritus.
    • Initial lesions showed an immunoblastic infiltrate on histological and electromicroscopic examination.
    • Peripheral blood revealed immature T cells, immunoblasts, and large Sézary cells.

    Findings:

    • The patient was diagnosed with a rare, high-grade malignant lymphoma, specifically cutaneous immunoblastic T-cell lymphoma.

  • Standard treatments including PUVA (psoralen-ultraviolet-A), prednisolone, and chemotherapy (COPP regimen, methotrexate) were ineffective.
  • Autopsy revealed systemic involvement with atypical lymphoid infiltration in multiple internal organs.

    • Implications:

    • This case highlights the importance of recognizing unusual presentations of cutaneous T-cell lymphomas.
    • The aggressive nature and poor response to therapy underscore the challenges in managing high-grade lymphomas.
    • Accurate differentiation from mycosis fungoides is essential for appropriate therapeutic strategies and patient outcomes.
