Case summary A 15-year-old male neutered domestic longhair cat was referred for investigation of a pancreatic nodule. Fine-needle aspiration of the nodule was performed on two occasions, 2 weeks apart, and cytology revealed pyogranulomatous inflammation and moderately dysplastic exocrine pancreatic epithelium, suspicious for neoplasia. Thoracic radiographs were unremarkable and a partial pancreatectomy was performed. On histopathology, the nodule was diagnosed as a moderately differentiated pancreatic adenocarcinoma. Two weeks after surgery, a firm subcutaneous nodule was detected on the left ventrolateral abdomen. Cytology of the nodule was suggestive of pancreatic carcinoma and needle tract seeding was suspected. With palliative treatment, the cat lived a further 136 days. Relevance and novel information To our knowledge, this represents the first report of suspected transabdominal needle tract seeding of pancreatic carcinoma following fine-needle aspiration in veterinary medicine. Veterinarians should consider this when discussing risks of pancreatic fine-needle aspiration with owners and should attempt to minimise the number of needle aspirations where possible.

A 77-year-old woman with epigastralgia was referred to our hospital. Abdominal computed tomography showed a hypointense mass in the pancreatic tail. Abdominal and endoscopic ultrasonography (EUS) showed a hypo-echoic mass, 25 × 25 mm in size, with pancreatic duct dilatation. EUS-guided fine-needle aspiration (EUS-FNA) was performed to the mass through gastric posterior wall. Pathological examination showed atypical cells growing papillary or tubular fashion, leading to the diagnosis of adenocarcinoma. Under the preoperative diagnosis of T2N0M0 pancreatic cancer, the patient underwent distal pancreatectomy and splenectomy. Macroscopic view of the resected specimen showed a presumed puncture-induced pancreatic pseudocyst adjacent to the pancreas. Pathological examination showed well-differentiated adenocarcinoma and a pseudocyst with presumed migrated atypical cells in the pseudocyst wall. The patient recovered uneventfully and has been on outpatient follow-up with adjuvant TS-1 therapy. Optimal treatment of pancreatic cancer naturally needs preoperative definitive diagnosis more strictly than other solid malignancies due to its much higher operative harm to the patients. EUS-FNA is a safe and effective diagnostic method but needs careful attention to the needle tract seeding.

Abstract Background and study aims Tumor seeding after endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is rare. A 53-year-old man underwent transesophageal EUS-FNA for diagnosis of a 6-cm mass in the mediastinum as seen by computed tomography (CT). Four weeks later, repeat CT scan revealed a mass in the esophageal wall. Upper gastrointestinal endoscopy confirmed a lesion in the mid-esophagus, which was biopsied and found to be consistent with needle tract seeding after EUS-FNA. Tumor seeding in the gastrointestinal wall or peritoneum after EUS-FNA is rare, but may adversely affect the prognosis. Indications for EUS-FNA must be carefully considered.
