Summary
Temporal artery involvement is rare in lymphoma. A biopsy confirmed follicular mixed cell lymphoma in a patient presenting with temporal artery nodules, highlighting the need for biopsy in differential diagnoses.
Area of Science:
- Oncology
- Pathology
- Rheumatology
Background:
- Giant cell arteritis classically involves temporal arteries.
- Lymphoma involvement of temporal arteries is exceptionally rare.
- Accurate diagnosis is crucial for appropriate patient management.
Observation:
- A 68-year-old male with a history of low-grade non-Hodgkin lymphoma presented with asymptomatic temporal artery nodules.
- Pulse was preserved despite the presence of nodules.
- Temporal artery biopsy was performed for diagnostic evaluation.
Findings:
- Biopsy revealed periarterial infiltration of mononuclear cells.
- Histopathology was consistent with follicular mixed cell lymphoma.
- This finding indicates lymphoma can infiltrate the temporal artery.
Implications:
- The differential diagnosis for temporal artery abnormalities should include lymphoma.
- Temporal artery biopsy is essential for diagnosing rare conditions.
- This case expands the understanding of extranodal lymphoma manifestations.
