A rare case of primary cutaneous pleomorphic large cell lymphoma in a young woman showed favorable prognosis. Local treatment led to no detectable spread, suggesting good outcomes for Ki-1-positive lymphomas without lymph node involvement.

Area of Science:

  • Dermatology
  • Oncology
  • Immunohistochemistry

Background:

  • Primary cutaneous lymphomas are rare malignancies affecting the skin.
  • Pleomorphic large cell lymphoma is a subtype that can present with varying clinical behaviors.

Observation:

  • A 21-year-old woman presented with a three-month history of a blue-reddish nodule on her left cheek.
  • Histopathological examination revealed a tumor composed of pleomorphic blast cells with high mitotic activity.
  • Immunohistochemical analysis showed tumor cells expressing CD3, CD4, HLA-DR, CD30 (Ki-1), and CD25.

Findings:

  • The excised tumor showed no systemic spread 22 months post-treatment.
  • This case supports recent findings on the favorable prognosis of primary cutaneous Ki-1-positive large cell lymphomas.

  • Histological malignancy patterns in localized disease may not always predict systemic spread.

    • Implications:

    • Local treatment may be sufficient for certain primary cutaneous Ki-1-positive large cell lymphomas.
    • Early diagnosis and targeted immunohistochemical analysis are crucial for determining prognosis.
    • Further research is warranted to understand the behavior and optimal management of these rare cutaneous lymphomas.
