Intraductal Papillary Neoplasms of the Bile Duct

International Journal of Hepatology, 2014
Intraductal papillary neoplasm of the bile duct (IPNB) is a rare variant of bile duct tumors characterized by papillary growth within the bile duct lumen and is regarded as a biliary counterpart of intraductal papillary mucinous neoplasm of the pancreas.

Intraductal Oncocytic Papillary Neoplasms [PDF]

American Journal of Surgical Pathology, 2019
Background: Intraductal oncocytic papillary neoplasm (IOPN) of the pancreas is a rare tumor. Recent molecular data indicate that it is distinct from other intraductal neoplasms; however, its clinicopathologic characteristics, especially the frequency/significance of an invasive carcinoma component, and biologic behavior remain ...

A huge intraductal papillary mucinous carcinoma of the bile duct treated by right trisectionectomy with caudate lobectomy

World Journal of Surgical Oncology, 2009
Background Because intraductal papillary mucinous neoplasm of the bile duct (IPMN-B) is believed to show a better clinical course than non-papillary biliary neoplasms, it is important to make a precise diagnosis and to perform complete surgical resection.

RNF43 Mutations in IPMN Cases: A Potential Prognostic Factor

Gastroenterology Research and Practice, 2020
An intraductal papillary mucinous neoplasm (IPMN) is a common pancreatic precursor lesion, and it often harbors mutations in KRAS, GNAS, and RNF43. To clarify the molecular profiles of IPMNs, we conducted mutation analysis of KRAS, GNAS, and RNF43 in 61 ...

Oncocytic-type intraductal papillary mucinous neoplasm (IPMN)-derived invasive oncocytic pancreatic carcinoma with brain metastasis - a case report

World Journal of Surgical Oncology, 2012
Pancreatic cancer is a lethal disease without effective treatments at present. It ranks as s as 4th and 5th in cancer-related mortality in the western countries and worldwide. Locally advanced pancreatic duct carcinoma (PDAC) and metastatic PDAC, usually

Pancreatic Adenocarcinoma: Diagnosis by Ultrasound‐Guided Fine‐Needle Aspiration—Cyto‐Histological Correlation and Experience at a Multidisciplinary Tertiary Reference Center

Diagnostic Cytopathology, Volume 54, Issue 6, Page 403-416, June 2026.
ABSTRACT Background Pancreatic adenocarcinoma (PDAC) is characterized by its poor prognosis. Cytology is essential for diagnostic confirmation and ancillary studies. The endoscopic ultrasound (EUS) set a precedent, facilitating cytological sampling through fine‐needle aspiration (FNA), with a sensitivity of 93% and a specificity of 95%.

Artificial intelligence in genitourinary pathology

Histopathology, Volume 88, Issue 1, Page 353-373, January 2026.
Artificial intelligence (AI) is now practical in genitourinary pathology. We synthesize evidence and economics into a two‐part playbook: VALIDATED (governance) and ORCHESTRATE (operations), to safely deploy AI tools across prostate, bladder, kidney and testis.

Intraductal oncocytic papillary neoplasm of the pancreas: a radio-pathological case study

JOP : Journal of the pancreas, 2010
Context An intraductal oncocytic papillary neoplasm is a rare pancreatic tumor with the potential of developing invasive carcinoma. Its differentiation from other cystic-like neoplasms of the pancreas, such as intraductal papillary mucinous neoplasms, is a challenge for pancreatic imaging.

MAML2‐Rearranged Hidradenoma of the Breast: Clinicopathologic and Molecular Analysis of Four Patients

Case Reports in Pathology, Volume 2026, Issue 1, 2026.
Hidradenoma (HA) is a rare, benign adnexal tumor typically arising in the skin, with only a few reported cases in the breast. Histologically, HA displays solid and cystic patterns with diverse cellular components. Although MAML2 gene rearrangement is observed in some cutaneous HAs, its significance in breast HA remains unclear.

Cystic Intraductal Papillary Neoplasm of the Bile Duct in the Left Lobe of the Liver With Associated Liver Atrophy: A Case Report

Clinical Case Reports, Volume 13, Issue 10, October 2025.
ABSTRACT Cystic IPNB is a rare liver disease with a high risk of malignant transformation (64%–89%) and poses diagnostic challenges. We describe a case of a 74‐year‐old woman with a large bilobar mucinous cyst in the left liver lobe associated with its atrophy managed with left hepatectomy.
