Area of Science:

  • Oncology
  • Hematology
  • Dermatopathology

Background:

  • Non-Hodgkin's lymphoma (NHL) encompasses diverse subtypes, with multi-lobed NHL recently identified as a distinct variant.
  • Primary cutaneous lymphomas involve the skin without systemic dissemination at diagnosis.

Observation:

  • A patient presented with a scalp nodule and associated bone defect on skull X-ray.
  • Immunophenotyping confirmed a B-cell proliferation, and histological examination revealed B-lymphocytes resembling centroblasts.
  • No other extra-cutaneous localizations were detected.

Findings:

  • This case represents the first documented instance of primary cutaneous multi-lobed B-cell NHL, confirmed by immunophenotyping.
  • The tumor exhibited characteristics of prominent extra-nodal involvement and large lymphoid cells with multi-lobed nuclei.

  • The patient showed a positive response to chemotherapy.

    • Implications:

    • The findings underscore the significance of multi-lobed NHL as a clinico-anatomical entity, particularly its potential for primary cutaneous presentation.
    • Recognizing this variant is crucial for accurate diagnosis and appropriate therapeutic strategies, given its distinct biological features and treatment response.
    • Further research into multi-lobed NHL, encompassing both T-cell and B-cell subtypes, is warranted to fully elucidate its pathogenesis and clinical behavior.
