DLL4 expression is a prognostic marker and may predict gemcitabine benefit in resected pancreatic cancer.

BACKGROUND: There is an increasing interest for Notch signalling pathway and particularly Delta-like ligand 4 (DLL4) as potential therapeutic target to improve outcome for patients with pancreatic ductal adenocarcinoma (PDAC). METHODS: Using immunohistochemistry (IHC) and tissue microarray (TMA), we assessed the expression patterns of DLL4, Notch1 and Notch3 in 151 patients from two independent cohorts of resected PDAC. We investigated the prognostic and the predictive significance of these proteins. RESULTS: High IHC DLL4 expression in cancer cells was associated with worse overall survival (OS) and disease-free survival (DFS) than low DLL4 expression (median OS: 12.9 vs 30.4 months, P=0.004 and median DFS: 8.8 vs 17.4 months, P=0.02). High DLL4 expression remained a significant negative prognostic factor in multivariate analysis (HR for OS: 2.1, P=0.02 and HR for DFS: 2.0, P=0.02). Low DLL4 abundance was associated with a longer OS-only for patients who received an adjuvant gemcitabine-based chemotherapy (P<0.001) but not for patients who did not receive gemcitabine (P=0.72). Furthermore, the interaction test for adjuvant gemcitabine therapy was statistically significant (P<0.001). The validating cohort recapitulated the findings of the training cohort. CONCLUSIONS: Low DLL4 abundance in tumour cells may predict the benefit from adjuvant gemcitabine therapy after PDAC resection.

Review of the quality of total mesorectal excision does not improve the prediction of outcome.

AIM: A fair to moderate concordance in grading of the total mesorectal excision (TME) surgical specimen by local pathologists and a central review panel has been observed in the PROCARE (Project on Cancer of the Rectum) project. The aim of the present study was to evaluate the difference, if any, in the accuracy of predicting the oncological outcome through TME grading by local pathologists or by the review panel. METHOD: The quality of the TME specimen was reviewed for 482 surgical specimens registered on a prospective database between 2006 and 2011. Patients with a Stage IV tumour, with unknown incidence date or without follow-up information were excluded, resulting in a study population of 383 patients. Quality assessment of the specimen was based on three grades including mesorectal resection (MRR), intramesorectal resection (IMR) and muscularis propria resection (MPR). Using univariable Cox regression models, local and review panel histopathological gradings of the quality of TME were assessed as predictors of local recurrence, distant metastasis and disease-free and overall survival. Differences in the predictions between local and review grading were determined. RESULTS: Resection planes were concordant in 215 (56.1%) specimens. Downgrading from MRR to MPR was noted in 23 (6.0%). There were no significant differences in the prediction error between the two models; local and central review TME grading predicted the outcome equally well. CONCLUSION: Any difference in grading of the TME specimen between local histopathologists and the review panel had no significant impact on the prediction of oncological outcome for this patient cohort. Grading of the quality of TME as reported by local histopathologists can therefore be used for outcome analysis. Quality control of TME grading is not warranted provided the histopathologist is adequately trained.

IGF-IR: a new prognostic biomarker for human glioblastoma.

BACKGROUND: Glioblastomas (GBMs) are the most common malignant primary brain tumours in adults and are refractory to conventional therapy, including surgical resection, radiotherapy and chemotherapy. The insulin-like growth factor (IGF) system is a complex network that includes ligands (IGFI and IGFII), receptors (IGF-IR and IGF-IIR) and high-affinity binding proteins (IGFBP-1 to IGFBP-6). Many studies have reported a role for the IGF system in the regulation of tumour cell biology. However, the role of this system remains unclear in GBMs. METHODS: We investigate the prognostic value of both the IGF ligands' and receptors' expression in a cohort of human GBMs. Tissue microarray and image analysis were conducted to quantitatively analyse the immunohistochemical expression of these proteins in 218 human GBMs. RESULTS: Both IGF-IR and IGF-IIR were overexpressed in GBMs compared with normal brain (P<10(-4) and P=0.002, respectively). Moreover, with regard to standard clinical factors, IGF-IR positivity was identified as an independent prognostic factor associated with shorter survival (P=0.016) and was associated with a less favourable response to temozolomide. CONCLUSIONS: This study suggests that IGF-IR could be an interesting target for GBM therapy.

Microsatellite instable vs stable colon carcinomas: analysis of tumour heterogeneity, inflammation and angiogenesis.

BACKGROUND: Microsatellite instability (MSI) accounts for 15% of all colorectal tumours. Several specific clinicopathologicals (e.g., preference for the proximal colon over the distal colon, improved prognosis and altered response to chemotherapeutics) are described for this subset of tumours. This study aimed to analyse morphological, inflammatory and angiogenic features of MSI vs microsatellite stable (MSS) tumours. METHODS: Twenty-seven MSS and 29 MSI, TNM stage matched, colorectal tumours were selected from the archive of the Department of Pathology, UZ Leuven. Morphology was analysed on haematoxylin-eosin sections. Immunohistochemistry for CD3, CD4, CD8, CD20 and CD68 was used to map tumour infiltration in both a digital and traditional microscope-based manner for all distinct morphological components of the tumour. CD31 immunostains were performed to assess angiogenesis. RESULTS: Morphological tumour heterogeneity was a marked feature of MSI tumours, occurring in 53% of the cases as compared with 11% of the MSS tumours (P<0.001). Digital immune quantification showed an increased number of tumour-infiltrating cytotoxic T-lymphocytes (CD8+) in MSI compared with MSS tumours for both the tumour (P=0.02) and peritumoural area (P=0.03). Traditional microscope-based quantification confirmed these results (P<0.001 for both) and, in addition, revealed large numbers of CD68+ macrophages in the peritumoural area of MSI cancers (P=0.001). Moreover, traditional microscope-based analysis was able to distinguish between lymphocytes directly infiltrating the tumoural glands (intra-epithelial) and those infiltrating only the neoplastic stroma around the glands (intratumoural). Quantification showed high numbers of intra-epithelial CD3+, CD4+, CD8+, CD20+ and CD68+ cells in MSI compared with MSS cancers (P<0.001, P=0.01, P<0.001, P<0.001 and P=0.006, respectively). Higher microvessel density (MVD) was observed in MSI tumours compared with their MSS counterpart. CONCLUSIONS: Mixed morphology, reflecting tumour heterogeneity, is an important feature of MSI tumours and may have both diagnostic and therapeutic impact. The inflammatory reaction also presented with significant differences in MSI vs MSS colorectal tumours. MSI cancers showed mainly infiltration by cytotoxic T-cells in both the tumour and the close border around the tumour, as well as increased intra-epithelial infiltration in contrast to MSS tumours. The type of immune cell and the compartment it resides in (intratumoural or intra-epithelial) depend both on MSI status and morphology. Finally, MSI tumours showed a higher angiogenic capacity represented by an increased MVD, hinting for possible therapeutic consequences.

Neoadjuvant immunotherapy in microsatellite instability-high (MSI-H) duodenal adenocarcinoma leads to pathological complete response and paves the way for new strategies.

Duodenal adenocarcinoma is a rare digestive cancer, often diagnosed at a late stage and harbours a poor prognosis. The arrival of immunotherapy has changed the prognosis of many neoplasia, including digestive adenocarcinomas with MSI-H status. Hereby, we describe three cases of MSI-H locally advanced duodenal adenocarcinoma who received neoadjuvant treatment with a PD1 inhibitor, pembrolizumab. A partial metabolic and endoscopic response was observed in all patients after 2 cycles. Duodenopancreatectomy was performed at the end of treatment (4-6 cycles), and anatomopathological analysis demonstrated pathological complete response in all patients. Our case series paves the way for prospectively exploring neoadjuvant immunotherapy in duodenal MSI-H adenocarcinoma and raises the question of organ sparing surgery in case of complete clinical response as observed in gastric and colo-rectal adenocarcinomas.

Epithelial expression of FHL2 is negatively associated with metastasis-free and overall survival in colorectal cancer.

BACKGROUND: Four-and-a-half LIM domains protein 2 (FHL2) is a component of the focal adhesion structures and has been suggested to have a role in cancer progression. It has been shown to be overexpressed in the colorectal cancer (CRC). METHODS: Here, we examined a possible prognostic value of FHL2 in CRC. Immunohistochemistry for FHL2 was performed on 296 CRCs without distant metastases at the time of surgery. Staining in the epithelial compartment was quantitatively evaluated using image analysis, and results were related to clinical variables. Antibody specificity was tested using small-interfering RNA transfection in hTERT-immortalised myofibroblasts. RESULTS: Varying degrees of cytoplasmic FHL2 expression by neoplastic epithelial cells were detectable in all cases. Higher FHL2 expression in the epithelial compartment was an independent adverse prognostic factor. Multivariate Cox analysis shows that expression in the tumour invasion front (P<0.001) as well as in the centre of the tumour (P<0.001) was associated with metachronous metastases independently of the clinicopathological variables; expression in the tumour invasion front was also associated with overall survival independently of the clinicopathological variables (P<0.01). CONCLUSION: Higher FHL2 expression is involved in CRC progression and correlates with the development of metachronous metastases and overall survival, suggesting that FHL2 is an independent adverse prognostic indicator for CRC.

Need for objective and reproducible criteria in histopathological assessment of total mesorectal excision specimens: lessons from a national improvement project.

AIM: Data on quality control of the pathologic evaluation of total mesorectal excision (TME) specimens are scarce. We aimed to assess differences between evaluation by local pathologists participating in PROject on CAncer of the REctum (PROCARE; a Belgian improvement project on rectal cancer) and by a review panel of experts. METHOD: Based on photographic material and histopathology slides, a Review Committee of gastrointestinal expert pathologists re-evaluated the mesorectal plane, the tumour differentiation grade, the (y)pT stage and the tumour regression grade in 444 patients previously routinely assessed by local pathologists. RESULTS: The surgical plane was reported in 89% of patients and the circumferential resection margin in 88% of patients by the local pathologist. The median number of lymph nodes harvested in patients undergoing neoadjuvant radiochemotherapy was 11 and 14 in the other patients. The Review Committee downgraded the surgical plane from (intra)mesorectal to intramuscular in 17% of patients, and upgraded it from intramuscular to (intra)mesorectal in 27%. Tumour differentiation grade, T stage and tumour regression grade differed between local pathologists and the Review Committee in 15%, 10% and 38%, respectively, of patients. T stage was upgraded, mainly from T2 to T3, in 8% of patients. Tumour regression was judged by the Review Committee to be less advanced in 15% of patients. CONCLUSION: Acknowledging some shortcomings, this study gives a realistic view of clinical practice. There are differences in interpretation with regard to both macroscopic and microscopic analysis of TME specimens. These findings indicate a need for more objective and reproducible criteria in histopathology. Being aware of this is a first step for improvement.

Pancreatic adenocarcinoma: general histological overview.

In Belgium, approximately 1100 new cases of pancreatic ductal adenocarcinoma are diagnosed each year. Although in the last twenty years several advances have been registered in the field of pancreatic pathology, few therapies are efficacious, and it remains one of the deadliest of all cancers. Histological variants with a somewhat different prognosis have been recognised, and precursor lesions identified. This article reviews the histological aspects of ductal adenocarcinoma, its variants and the precursor lesions. Study and knowledge of these precursor lesions offers the best hope for treating pancreatic cancer before an incurable invasive tumour develops.

Belgian guidelines for pathology reporting of neuroendocrine neoplasms of the pancreaticobiliary and gastrointestinal tract.

Since neuroendocrine neoplasms are rare tumors, registration of patient data in national and multinational registries is recommended. Indeed, this will facilitate multicenter studies on the epidemiology, efficacy and safety of diagnostic and therapeutic strategies for well-differentiated neuroendocrine tumors as well as for neuroendocrine carcinomas. In Belgium, data on patient and tumor characteristics of all newly diagnosed malignancies have been collected in the Belgian Cancer Registry since 2004 including anonymized full pathological reports. The Digestive Neuroendocrine Tumor (DNET) registry collects information on classification, staging, diagnostic tools and treatment in a prospective national online database. However, the terminology, classification and staging systems of neuroendocrine neoplasms have changed repeatedly over the past 20 years as a result of a better understanding of these rare tumors, by joining forces internationally. These frequent changes make it very difficult to exchange data or perform retrospective analyses. For optimal decision making, for a clear understanding and to allow reclassification according to the latest staging system, several items need to be described in the pathology report. This paper provides an overview of the essential items in reporting neuroendocrine neoplasms of the pancreaticobiliary and gastrointestinal tract.

Clinicopathological significance of indoleamine 2,3-dioxygenase 1 expression in colorectal cancer.

BACKGROUND: Indoleamine 2,3-dioxygenase 1 (IDO1) is a tryptophan-catabolising enzyme that induces immune tolerance by modulating T-cell responses. Carcinomas may create an immunosuppressive state via IDO1 expression. Here we examined a possible contribution of IDO1 on this phenomenon and investigated whether IDO1 has prognostic value in colorectal cancer (CRC). METHODS: IDO1 expression was investigated by quantitative PCR and western blotting in three colon cancer cell lines, in basal state and after interferon (IFN)-γ stimulation. Semi-quantitative immunohistochemistry was used to evaluate IDO1 expression in 265 pT1-4N0-2Mx-staged CRCs. Results were related to clinical variables and correlated with amounts of CD3(+) and CD8(+) T lymphocytes, which were quantitatively evaluated using image analysis. RESULTS: In vitro expression of IDO1 depended on IFN-γ stimulation. Higher IDO1 expression at the tumour invasion front was an independent adverse prognostic factor in pT1-4N1Mx-staged CRC. It was associated with overall survival (P=0.001) and with metachronous metastases (P=0.018). IDO1 expression was not associated with the presence of CD3(+) or CD8(+) T lymphocytes. CONCLUSION: Higher IDO1 expression at the tumour invasion front is involved in CRC progression and correlates with impaired clinical outcome, suggesting that IDO1 is an independent prognostic indicator for CRC.

Short course chemotherapy followed by concomitant chemoradiotherapy and surgery in locally advanced rectal cancer: a randomized multicentric phase II study.

BACKGROUND: Induction chemotherapy has been suggested to impact on preoperative chemoradiation efficacy in locally advanced rectal cancer (LARC). To evaluate in LARC patients, the feasibility and efficacy of a short intense course of induction oxaliplatin before preoperative chemoradiotherapy (CRT). PATIENTS AND METHODS: Patients with T2-T4/N+ rectal adenocarcinoma were randomly assigned to arm A-preoperative CRT with 5-fluorouracil (5-FU) continuous infusion followed by surgery-or arm B-induction oxaliplatin, folinic acid and 5-FU followed by CRT and surgery. The primary end point was the rate of ypT0-1N0 stage achievement. RESULTS: Fifty seven patients were randomly assigned (arm A/B: 29/28) and evaluated for planned interim analysis. On an intention-to-treat basis, the ypT0-1N0 rate for arms A and B were 34.5% (95% CI: 17.2% to 51.8%) and 32.1% (95% CI: 14.8% to 49.4%), respectively, and the study therefore was closed prematurely for futility. There were no statistically significant differences in other end points including pathological complete response, tumor regression and sphincter preservation. Completion of the preoperative CRT sequence was similar in both groups. Grade 3/4 toxicity was significantly higher in arm B. CONCLUSIONS: Short intense induction oxaliplatin is feasible in LARC patients without compromising the preoperative CRT completion, although the current analysis does not indicate increased locoregional impact on standard therapy.

Contribution of CXCR4 and SMAD4 in predicting disease progression pattern and benefit from adjuvant chemotherapy in resected pancreatic adenocarcinoma.

BACKGROUND: Prognosis of patients with pancreatic adenocarcinoma is poor. Many prognostic biomarkers have been tested, but most studies included heterogeneous patients. We aimed to investigate the prognostic and/or predictive values of four relevant biomarkers in a multicentric cohort of patients. PATIENTS AND METHODS: A total of 471 patients who had resected pancreatic adenocarcinoma were included. Using tissue microarray, we assessed the relationship of biomarker expressions with the overall survival: Smad4, type II TGF-ß receptor, CXCR4, and LKB1. RESULTS: High CXCR4 expression was found to be the only independent negative prognostic biomarker [hazard ratio (HR) = 1.74; P < 0.0001]. In addition, it was significantly associated with a distant relapse pattern (HR = 2.19; P < 0.0001) and was the strongest prognostic factor compared with clinicopathological factors. In patients who did not received adjuvant treatment, there was a trend toward decrease in the overall survival for negative Smad4 expression. Loss of Smad4 expression was not correlated with recurrence pattern but was shown to be predictive for adjuvant chemotherapy (CT) benefit (HR = 0.59; P = 0.002). CONCLUSIONS: CXCR4 is a strong independent prognostic biomarker associated with distant metastatic recurrence and appears as an attractive target to be evaluated in pancreatic adenocarcinoma. Negative SMAD4 expression should be considered as a potential predictor of adjuvant CT benefit.

New strategies and designs in pancreatic cancer research: consensus guidelines report from a European expert panel.

Although the treatment of pancreatic ductal adenocarcinoma (PDAC) remains a huge challenge, it is entering a new era with the development of new strategies and trial designs. Because there is an increasing number of novel therapeutic agents and potential combinations available to test in patients with PDAC, the identification of robust prognostic and predictive markers and of new targets and relevant pathways is a top priority as well as the design of adequate trials incorporating molecular-driven hypothesis. We presently report a consensus strategy for research in pancreatic cancer that was developed by a multidisciplinary panel of experts from different European institutions and collaborative groups involved in pancreatic cancer. The expert panel embraces the concept of exploratory early proof of concept studies, based on the prediction of response to novel agents and combinations, and randomised phase II studies permitting the selection of the best therapeutic approach to go forward into phase III, where the recommended primary end point remains overall survival. Trials should contain as many translational components as possible, relying on standardised tissue and blood processing and robust biobanking, and including dynamic imaging. Attention should not only be paid to the pancreatic cancer cells but also to microenvironmental factors and stem/stellate cells.

Hepatic expression of CCL2 in alcoholic liver disease is associated with disease severity and neutrophil infiltrates.

Serum levels and liver expression of CCL2 are increased in patients with alcoholic hepatitis (AH). In an experimental model of alcoholic liver disease (ALD), CCL2 was implicated in proinflammatory cytokines activation and hepatic lipid metabolism, but its role in human disease is currently unknown. In a large cohort of ALD patients, we analysed plasma levels and liver expression of CCL2 and their association with liver disease severity and histological lesions. We also studied the relationship between -2518 A > G CCL2 and CCR2 190 A/G polymorphisms and severity of ALD. We show that CCL2 plasma levels are increased in ALD patients compared with healthy subjects. AH patients had significantly higher plasma levels and hepatic expression of CCL2 than patients without AH. Plasma levels and hepatic expression of CCL2 were associated with disease severity. CCL2 liver expression was correlated with neutrophil infiltrate and interleukin (IL)-8 expression, but not with steatosis. Moreover, there were more G-allele carriers of -2518 A > G CCL2 polymorphism in severe AH patients than in other ALD patients. Our results demonstrate that CCL2 is increased in ALD, particularly in severe forms, and suggest a role for CCL2 in the pathogenesis of ALD via neutrophil recruitment.

Risk adjusted benchmarking of clinical anastomotic leakage rate after total mesorectal excision in the context of an improvement project.

AIM: Anastomotic leakage (AL) after total mesorectal excision (TME) is a major adverse event. This study evaluates variability in AL between centres participating on a voluntary basis in PROCARE, a Belgian improvement project, and how further improvement of the AL rate might be achieved. METHOD: Between January 2006 and March 2011, detailed data on 1815 patients (mean age 65.5 years, 63% male) who underwent elective TME with colo-anal reconstruction for rectal cancer were registered by 48 centres. Variability in early clinical AL rate was analysed before and after adjustment for gender, age > 60 years, American Society of Anesthesiologists score of 3 or more and body mass index > 25 kg/m(2). RESULTS: The overall AL rate was 6.7% (95% CI 5.6%-7.9%). Early AL required reoperation in 86.8% of patients. It increased length of hospital stay from 14.7 days to 32.4 days and in-hospital mortality from 1.1% to 4.8%. Statistically significant variability in AL rate between centres was not observed, either before or after risk adjustment. Nonetheless, further improvement may be achievable in some centres by targeting the adjusted performance of better performing centres. These centres used neoadjuvant treatment, rectal irrigation, mobilization of the splenic flexure, resection of the sigmoid colon, side-to-end colo-anastomosis with or without pouch and defunctioning stoma at primary surgery in a significantly higher proportion of patients than less well performing centres. CONCLUSION: The overall AL rate was low but needs to be interpreted with caution because of incomplete registration. Further improvement might be achieved by adopting the approach of better performing centres.

[Multidisciplinary management of hepatocellular carcinoma in cirrhotic patients]. / Traitement du carcinome hépato-cellulaire chez le patient cirrhotique: la nécessité d'une approche pluridisciplinaire.

The treatment of hepatocellular carcinoma (HCC) in cirrhotic patients is challenging: the incidence is increasing, the cirrhosis dramatically limits the tolerance to treatment possibilities, there are many therapeutic modalities but resources are limited, namely in the context of organ shortage for transplantation. Liver transplantation (LT) is the optimal treatment as it combines the largest tumor resection possible and the correction of the underlying liver disease. Due to organ shortage however, LT is reserved for early-stages HCC. Surgical resection and radiofrequency destruction represent potentially curative options in highly selected patients. Arterial embolizations, chemo- or radio-embolizations, allow local tumor control but are not curative. These techniques could be performed before surgical resection or LT, to downstage the tumor and/or to control tumor progression while waiting for a graft. Finally, sorafenib is the only systemic treatment which has shown a survival benefit in advanced HCC. The benefit of combination of sorafenib and surgical treatments remains undetermined. The challenge in the management of HCC in cirrhotic patients is to integrate both individual (age, comorbidities, cirrhosis stage, tumor stage, specific contraindications to LT, etc.) and collective variables (expected waiting time before LT) to determine the best therapeutic option for each patient. In this process, multidisciplinarity is a key for success.

Immature squamous metaplasia of esophageal glands associated with squamous cell carcinoma.

Background: Esophageal immature squamous metaplasia is hardly reported in the literature. This entity can, however, be misinterpreted as high grade dysplasia or invasive squamous cell carcinoma and hence represent a potential pitfall. Case presentation: Histopathological examination of a superficial esophageal lesion removed by endoscopic submucosal dissection revealed a squamous cell carcinoma associated with immature squamous cell metaplasia arising from esophageal glands. Immunohistochemical stainings allowed to distinguish malignant from metaplastic cells. Conclusions: Immunohistochemistry for Ber-EP4 is helpful in making the distinction between esophageal squamous cell carcinoma and immature squamous metaplasia. This can avoid overstaging and overtreatment, especially in early esophageal cancer.

Polypoid colon mucosa in a leukemia patient.

A woman, followed for chronic myeloid leukaemia, presented for a routine examination. Her medical history was marked by recurrent Helicobacter pylori gastritis and polymyalgica rheumatica. She was under dasatinib and hormone replacement therapy. At clinical examination, she complained about digestive disorders with altered bowel habits. Biology, including leucocyte count, remained normal. A colonoscopy was performed. Endoscopic examination revealed a colonic mucosa covered by multiple tiny nodular lesions (<5mm) from the hepatic angle to the sigmoid and with an abnormal pattern of vascularisation (Fig. 1). Staged biopsies were taken. Microscopic examination revealed discrete achi-tectural distortions. The stroma contained a mixed inflammatory infiltrate composed of neutrophils, eosinophils and lymphocytes. Immunohistochemistry for CD3, CD5, CD20 and CD79 did not bring arguments for a lymphoma. There were no malignant or dysplastic cells. (Fig. 2). What is your diagnosis?

Isolated oesophageal Crohn's disease mimicking oesophageal carcinoma treated by Merendino procedure.

Oesophageal involvement is a very rare presentation of Crohn's disease. It can occur as an isolated mass causing dysphagia and can be mistaken for malignancy. Here, we report a case of a 75-year-old woman presenting with dysphagia and weight loss. Gastroscopy showed an ulcerating mass, and her barium swallow showed a bird beak appearance at the level of the gastro-oesophageal junction (GEJ). Repetitive biopsies were inconclusive. Fluorodeoxyglucose-positron emission tomography showed high glucose uptake (standardised uptake value: 10.2) at the level of the GEJ. Endoscopic ultrasound classified the lesion as uT3N1. Step-by-step surgical exploration revealed an oesophageal mass. A frozen section examination showed an absence of malignancy and the presence of inflammatory tissue. A partial oesophagogastrostomy was performed, and reconstruction was achieved by a Merendino procedure. Definitive histopathological examination revealed isolated oesophageal Crohn's disease.

Case report: Sclerosed hemangioma of the liver: A diagnostic challenge.

Hemangiomas are the most common noncystic benign hepatic tumors and are usually incidentally discovered during routine radiological examinations. The diagnosis of hepatic hemangiomas with a typical presentation is generally easy with plain and cross-sectional imaging; however, it can be complicated when hemangiomas undergo histological changes such as fibrosis. Sclerosed hepatic hemangioma (SHH) is the extreme presentation of this fibrotic process. These atypical lesions can be misdiagnosed as primary hepatic malignancies or metastasis. Their diagnosis is established by histological examination. We report the case of a patient with an SHH, which was misdiagnosed as an intrahepatic cholangiocarcinoma. This article's aim is to draw attention to this infrequent pathology and underline the features of this benign tumor that could suggest its diagnosis prior to surgery to avoid unnecessary hepatic resections.
