Metastatic neoplasms to the pancreas diagnosed by fine-needle aspiration/biopsy cytology: A 15-year retrospective analysis.

Background: Metastatic tumors to the pancreas are rarely encountered and diagnostically challenging. We aspired to determine the incidence and origin of all metastases to the pancreas at our institution, and to examine their clinicopathologic and cytomorphologic features. We also sought to ascertain the effect of endoscopic ultrasound (EUS) guidance implementation.

Metastatic genitourinary cancer diagnosed by body fluid cytology: clinicopathologic and cytomorphologic correlation.

Introduction: Malignant effusions secondary to genitourinary cancers constitute less than 5% of metastatic malignancies. Because of their rarity, definitive cytodiagnosis may be challenging. Our study aims to examine the incidence of malignant fluids secondary to genitourinary cancers in our institution, and to characterize their clinicopathologic and cytomorphologic features.
