Background:

  • Natural Killer (NK) cell lymphomas are rare malignancies.
  • Extranasal NK cell lymphomas often present with unique clinical and pathological features.
  • CD56 positivity and absence of monoclonal TCR gene rearrangement are characteristic markers.

Observation:

  • A 54-year-old male presented with a fungating left flank mass.
  • Histological examination confirmed cutaneous extranasal T/NK cell lymphoma.
  • The tumor exhibited characteristic immunophenotypic markers of NK cell origin.

Findings:

  • The case represents a rare presentation of cutaneous extranasal T/NK cell lymphoma.
  • Diagnostic challenges include differentiating from other cutaneous neoplasms.
