Summary
This study details a rare cutaneous extranasal T/natural killer (NK) cell lymphoma case. It highlights the importance of accurate diagnosis and treatment strategies for this aggressive lymphoma subtype.
Area of Science:
- Oncology
- Hematology
- Dermatopathology
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.
- The literature review provides insights into this specific lymphoma subtype.
Implications:
- Accurate diagnosis is crucial for appropriate patient management.
- Understanding the prognosis and treatment options is vital for improving outcomes.
- This case contributes to the limited literature on extranasal NK cell lymphomas.
