Plain-English summary
This study looked at three pets that developed new tumors along the path of a needle after having a fine needle aspiration biopsy, which is a procedure used to collect samples from tumors. Two of the pets were dogs with transitional cell carcinoma, a type of bladder cancer, and one was a cat with adenocarcinoma, a type of lung cancer. After the biopsies, the tumors grew along the area where the needle was inserted, which is something that hasn't been documented before for lung cancer in pets. This finding highlights a potential risk associated with this type of biopsy procedure.
Abstract
This paper reports three clinical cases of needle tract implantation of neoplastic cells on the abdominal and thoracic wall after ultrasound (US) fine needle aspiration biopsy (FNAB). Primary tumors were two transitional cell carcinomas of the urinary bladder (2 dogs) and one pulmonary adenocarcinoma (1 cat). All three masses grew up along the needle tract. To our knowledge, the seeding of pulmonary adenocarcinoma cells after FNAB on the thoracic wall has never been reported in veterinary medicine.
