Complicated course of biliary inflammatory myofibroblastic tumor mimicking hilar cholangiocarcinoma: A case report and literature review. World J Clin Cases 2021; 9:6155-6169. [PMID: 34368338 PMCID: PMC8316968 DOI: 10.12998/wjcc.v9.i21.6155] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 04/30/2021] [Accepted: 05/20/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The inflammatory myofibroblastic tumor (IMT) is a rare, idiopathic, usually benign, mass-forming disease with myofibroblastic proliferation and a varying amount of inflammatory cells. Although it can affect various organs, the biliary tract is a rare localization of primary IMT, clinically, endoscopically and radiologically imitating cholangiocarcinoma. The treatment options are based only on clinical practice experience.
CASE SUMMARY A 70-year-old woman was referred to our center due to progressive fatigue, weight loss, abdominal pain, night sweats, and elevated liver enzymes. Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography (ERCP) revealed proximal common hepatic duct and hilar biliary strictures extending bilaterally to lobular bile ducts. Although initial clinical, endoscopic and radiological signs were typical for hilar cholangiocarcinoma, histological examination showed no signs of malignancy. In total, 8 biopsies using different approaches were performed (several biopsies from dominant stricture during ERCP and direct cholangioscopy; ultrasound-guided liver biopsy; diagnostic laparoscopy with liver and lymph node biopsies). Histological examination revealed signs of IMT, and the final diagnosis of biliary IMT was stated. Although IMT is usually a benign disease, in our case, it was complicated. All pharmacological treatment measures were ineffective. The patient still needs permanent stenting, suffers from recurrent infections and mechanical jaundice. Despite that, the patient already survived 24 mo.
CONCLUSION IMT presenting with hilar biliary strictures is a unique diagnostic and clinical challenge as it is indistinguishable from cholangiocarcinoma, and there are no evidence-based treatment options. Our goal is to increase the understanding of this rare disease and its possible course.

Abstract
Inflammatory myofibroblastic tumours (IMTs) are rare benign neoplasms of intermediate malignant potential that are found in the lungs and rarely at extrapulmonary sites common in children and young adults. IMTs tend to be locally invasive and have some amount of metastatic potential as well. We present two cases of IMTs involving the duodenum, pancreas and distal bile duct. The first case presented with extensive involvement of the first three parts of the duodenum and head of the pancreas, while the second presented with a pancreatic and biliary tree involvement. Upon examinations and investigations, these tumours mimicked malignant neoplasms. A Whipple procedure for surgical resection was undertaken in both cases. The histological findings showed fascicles of spindle cells with infiltration of lymphocytes and plasma cells. The inflammatory myofibroblastic tumour was diagnosed based on pathological grounds with immunohistochemistry. Preoperative diagnosis of IMTs is difficult and complete surgical resection is the primary treatment.

Abstract
A 64-year old Chinese male patient was admitted to our hospital because of severe
jaundice that persisted for 2 months. No swollen lymph nodes or hepatosplenomegaly was
detected on physical examination. His laboratory data indicated high levels of direct
bilirubin, alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase.
No abnormality was revealed on abdominal computed tomography (CT). However, positron
emission tomography (PET)-CT revealed diffuse hypermetabolism in the liver and spleen.
Ultimately, liver biopsy guided by PET-CT was performed, revealing that atypical
lymphocytes diffusely infiltrated the liver. The immunohistochemical analysis demonstrated
that the tumor cells were positive for CD20, Bcl-2, Bcl-6, MUM1, and c-Myc but negative
for CD3, CD4, CD8, and CD10. Based on these findings, this patient was diagnosed with
primary hepatosplenic diffuse large B-cell lymphoma. After the definite diagnosis, he
received chemotherapy and remained in good health as of September 2019.

Abstract
Unusual pathologies are occasionally found at laparoscopy when appendicitis is suspected. We present a case of strangulated inflammatory fibrous pseudotumour of the omentum presenting in a similar fashion to appendicitis. The infarcted omentum was excised, facilitating prompt resolution of symptoms.

Abstract
INTRODUCTION Biliary inflammatory pseudotumors (IPTs) represent an exceptional benign cause of obstructive jaundice. These lesions are often mistaken for cholangiocarcinomas and are treated with major resections, because their final diagnosis can be achieved only after formal pathological examination of the resected specimen. Consequently, biliary IPTs are usually managed with unnecessary major resections. PRESENTATION OF CASE A 71-year-old female patient underwent an extra-hepatic bile duct resection en-bloc with the gallbladder and regional lymph nodes for an obstructing intraluminal growing tumor of the mid common bile duct (CBD). Limited resection was decided intraoperatively because of negative for malignancy fast frozen sections analysis in addition to the benign macroscopic features of the lesion. Histologically the tumor proved an IPT, arising from the bile duct epithelium, composed of inflammatory cells and reactive mesenchymal tissues. DISCUSSION The present case underlines the value of intraoperative reassessment of patients undergoing surgical resection for histopathologically undiagnosed biliary occupying lesions, in order to optimize their surgical management. CONCLUSION The probability of benign lesions mimicking cholangiocarcinoma should always be considered to avoid unnecessary major surgical resections, especially in fragile and/or elderly patients.
