Background: Inflammatory pseudotumor (IPT) is a rare space-occupying lesion of the liver that can be clinically confused with a malignant process.
Case Report: A 28-year-old male presented with fever and a palpable, firm liver. Ultrasonography and computed tomography revealed a mass in the right lobe of the liver. Fine needle aspiration biopsy (FNAB) under ultrasonographic guidance showed inflammatory cells, fibroblasts and a few hepatocytes. A diagnosis of inflammatory pseudotumour was suggested and confirmed on a true-cut biopsy.
Conclusion: The cytologic appearance of IPT is characteristic. FNAB under ultrasonographic is a quick and easy technique for its diagnosis and differentiation from malignant space-occupying lesions.

Background: Malignant transformation (MT) of mature cystic teratoma (MCT) has a poor prognosis, especially in advanced cases. Concurrent chemoradiotherapy (CCRT) has an inhibitory effect on MT.
Case Summary: Herein, we present a case in which CCRT had a reduction effect preoperatively.

To investigate the combined application of cytology, cell block histology and immunohistochemistry to improve the diagnostic accuracy of solid pancreatic lesions in endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) samples. The pathological data of EUS-FNA in 311 cases of solid pancreatic lesions submitted to the Second Hospital of Hebei Medical University, Shijiazhuang, China from May 2019 to September 2023 were retrospectively analyzed. The cases included pancreatic ductal adenocarcinoma (PDAC, 172 cases), solid pseudopapillary neoplasm (SPN, 12 cases), neuroendocrine tumors (PNET, 14 cases) and chronic pancreatitis (113 cases).

A 12 yr old female spayed American Staffordshire terrier was referred for stranguria, pollakiuria, and concern for a mass in the trigone of the urinary bladder. A urinalysis and abdominal ultrasound were performed to further investigate the bladder mass. Nematode larvae were identified in the urine, termed microfilaruria, while a caudal abdominal mass was found on ultrasound impinging on the urethra.

Background: Lymphoma arises from transformed lymphoid cells. Although surgical excision biopsy is the standard diagnostic tool for patients with lymphoma, image-guided fine-needle aspiration (FNA) or core needle biopsy (CNB) is considered an alternative diagnostic option.
Objective: To assess the diagnostic accuracy and safety of ultrasound (US)-guided core needle biopsy (CNB) in patients with lymphoma.
