  • Fine needle aspiration biopsy(FNAB) has been used for many decades in the diagnosis of benign and malignant tumors of thyroid gland. Complications of thyroid fine-needle aspiration biopsy(FNAB) are extremely rare. Hematoma formation is the most commonly encountered complication. However, massive intrathyroid unilateral hemorrhage and hematoma formation inducing upper airway distress rarely occurs. Here, we report two cases diagnosed as having hematoma that caused upper airway distress after FNAB for thyroid nodule.

  • A 30-year-old woman who was diagnosed as peripheral neuroblastoma by fine needle aspiration of a soft mass of the right upper arm is described. She presented a slowly growing, soft mass of the right upper arm for 1 month. The right humerus revealed no abnormal finding on X-ray. Ultrasonogram of the right upper arm revealed a well demarcated, smooth marginated solid mass without invasion of adjacent structures. Fine needle aspiration was done under the impression of soft tissue tumor with undetermined biologic behavior. The aspirates were highly cellular and the tumor cells were dispersed both singly and in clusters of varying size. The clusters occasionally showed a central capillary core and rosette-like structures. The tumor cells were small in size and had a small to medium amount of cytoplasm. Some of them revealed slender cytoplasmic processes. The nuclei showed distinct nuclear membranes, finely clumped chromatin and small conspicuous nucleoli. Cellular pleomorphism or mitotic figure was not definite. These cytologic findings were interpreted as a malignant, non-lymphomatous small round cell tumor, most likely representing peripheral neuroblastoma or Ewing's sarcoma. Final diagnosis was confirmed by simple excision as peripheral neuroblastoma.

  • Background and Objectives: Fine needle aspiration (FNA) cytology is a simple, safe and relatively accurate procedure of diagnosing thyroid nodules. Although the frozen section biopsy is well known as more reliable method than FNA and has high specificity, whether it is necessary it leaves room for adverse criticism. Authors have compared preoperative FNA cytology and frozen section biopsy with permanent histologic findings and evaluated the significance of FNA cytology and frozen section biopsy. Materials and Methods: The medical records of 110 patiens who underwent FNA cytology and frozen section during thyroidectomy from September. 1997 to December. 2001 at the Department of Otolaryngology, School of Medicine, Keimyung University were analyzed retrospectively. Results: Sensitivity, specificity, accuracy of FNA was 75%, 91.4%, and 85.5% respcetively. Sensitivity, specificity and accuracy rate of frozen section biopsy were 92.5%, 100% and 97.3% respectively. Conclusion: FNA is simple, with rare complication and its diagnostic accuracy is comparatively so high that it is being used as primary test to diagnosis thyroid nodules. But frozen section is more accurate and may be helpful to suspicious FNA findings or if it beyond capacity of FNA. Therefore despite of the fact that the intra-operative frozen is more expensive and time consuming, it is very helpful to the treatment of thyroid nodules by using jointly with FNA.
