Malignant seeding after fine-needle aspiration biopsy of the pancreas
Diagnostic Imaging in Clinical Medicine
|January 1, 1985
Abstract:
The authors report the case of a patient affected with carcinoma of the pancreas who underwent fine-needle aspiration biopsy under ultrasonic guidance. 2 months later, a peritoneal metastasis was found during laparotomy at the site of the previous biopsy. This is the third reported case in the literature of neoplastic dissemination after fine-needle biopsy, a traditionally safe diagnostic procedure.
Insights
Fine-needle aspiration biopsy for pancreatic cancer can potentially lead to tumor cell spread. This rare complication, neoplastic dissemination, highlights the need for careful consideration of biopsy techniques.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Fine-needle aspiration biopsy (FNAB) is a common diagnostic tool.
- Pancreatic carcinoma diagnosis often involves FNAB under image guidance.
- FNAB is generally considered a safe procedure with minimal complications.
Observation:
- A patient with pancreatic carcinoma underwent ultrasound-guided FNAB.
- Two months post-biopsy, peritoneal metastasis was detected at the biopsy site during laparotomy.
Findings:
- This case represents the third reported instance of neoplastic dissemination following FNAB.
- The findings suggest a potential risk of tumor cell seeding associated with FNAB in pancreatic cancer.
Implications:
- Further research into minimizing the risk of tumor spread during FNAB is warranted.
- Clinicians should be aware of this rare but serious complication.
- Alternative diagnostic methods or modifications to FNAB technique may be considered for pancreatic malignancies.
