A 14- year-old spayed female miniature Dachshund presented to our hospital with a mass at a previous incision site 7 months after the removal of a lung adenosquamous cell carcinoma (ASCC). Needle tract implantation (NTI) caused by fine needle biopsy was presumed as the cause of the mass. Extended resection of the mass was performed and histopathological examination revealed ASCC and thyroid transcription factor-1 (TTF-1) positivity. No local recurrence was observed; however, the dog died. The incidence of NTI in lung ASCC in dogs is unknown. However, the development of NTI should be monitored.
