Nasal NK/T-cell lymphoma, a rare condition, can mimic other facial conditions, leading to delayed diagnosis. This case highlights the aggressive nature and poor prognosis of this lymphoma, even with prompt treatment.
Area of Science:
- Oncology
- Pathology
- Immunology
Background:
- Nasal NK/T-cell lymphoma, previously known as midline lethal granuloma, is a rare clinicopathological entity.
- Recognized as distinct by WHO in 2001 due to advancements in histology and immunohistochemistry.
Observation:
- A 22-year-old insulin-dependent diabetic woman presented with rapidly progressing mid-facial swelling after trauma.
- Initial diagnosis was facial cellulitis, but the condition evolved into midline destructive disease.
Findings:
- Histological examination confirmed Natural Killer/T-cell lymphoma (NK/T-cell lymphoma).
- Differential diagnoses include cellulitis, invasive fungal infections, Wegener's granulomatosis, and actinomycosis.
- The patient's atypical presentation led to delayed diagnosis and treatment.
Implications:
- This case underscores the importance of considering NK/T-cell lymphoma in mid-facial destructive lesions.
- Despite radiotherapy and chemotherapy, the prognosis for nasal NK/T-cell lymphoma remains poor.
- Early and accurate diagnosis is crucial but challenging due to atypical presentations.
