Summary
Fine-needle aspiration can cause infarction in Warthin's tumours, a common salivary gland neoplasm. This study found at least 9% of these benign tumours experienced infarction in situ after aspiration, impacting diagnosis.
Area of Science:
- Oncology
- Pathology
- Radiology
Background:
- Warthin's tumour (cystadenolymphoma) is the second most frequent salivary gland tumour.
- It is frequently detected during head and neck ultrasonography.
- Fine-needle aspiration is a standard diagnostic method.
Observation:
- This study retrospectively analyzed 76 patients with Warthin's tumours.
- Seven cases of Warthin's tumours exhibiting radiological signs of infarction in situ were identified.
- The incidence of infarction post-fine-needle aspiration in lesions remaining in situ was approximately 9%.
Findings:
- Infarction following fine-needle aspiration is a recognized complication in Warthin's tumours.
- Radiological evidence of infarction in situ occurred in at least 9% of cases studied.
- This complication should be considered in the differential diagnosis of Warthin's tumours.
Implications:
- Pre-aspiration patient counseling should include the possibility of infarction and associated symptoms.
- This finding may influence the interpretation of imaging and clinical presentation of Warthin's tumours.
- Further research into the mechanisms and management of post-aspiration infarction is warranted.
