Objective: Primary gall bladder melanoma is a rare and controversial entity. So far, only 36 cases are documented in the literature. Metastatic melanoma targeting the gall bladder, however, has been reported to occur in about 15-20% of melanoma patients and is much more common. Methods: Based on the case of a 58-year-old woman presenting with multiple melanoma nodules in the gall bladder, we searched in the available literature in PubMed for articles describing a "primary melanoma of the gallbladder" regardless of language used...

Pancreatic and gastric heterotopia is an uncommon congenital anomaly in which gastric and/or pancreatic tissue is found outside of its anatomic location. In the majority of patients, lesions are found incidentally because they tend to be asymptomatic. However, lesions may become symptomatic when inflammation, obstruction, and bleeding occurs. Depending on tissue size and location they can harvest a landscape of nonspecific symptoms, causing a delay in diagnosis. Heterotopic tissue of either gastric or pancreatic origin have been reported in literature, however the presence of combined gastric and pancreatic heterotopic tissue is exceedingly rare...

Intracystic papillary neoplasm (ICPN) of gallbladder is a comparatively new concept and is described as pre-malignant lesions in Nakanuma et al. (In: Bosman et al. (eds) WHO Classification of Tumours of the Digestive System, World Health Organization of Tumours, IARC, Lyon, 2010). ICPN with high-grade intraepithelial neoplasia is understood to include intraepithelial carcinoma or noninvasive carcinoma. And lesions with invasive cancer components are classified as ICPN with an associated invasive carcinoma [1]...

Ultrasound is a frequently used diagnostic tool for gallbladder diseases. Polypoid lesions are commonly depicted at routine abdominal ultrasonography (US). The characteristics of these lesions vary. Since most early malignant tumors in the gallbladder are asymptomatic, differentiation between malignancy and benignity is crucial. Knowledge of gallbladder polypoid lesions is important so that they can be appropriately included in the differential diagnosis in patients presenting with intra-gallbladder nodules on US...

Gall-bladder diseases are common in dogs and two-dimensional ultrasonography is a current standard method for diagnosis and treatment planning. However, findings from this modality can be nonspecific. The aim of this retrospective, case series study was to describe conventional and contrast-enhanced ultrasound (using SonoVue® ) findings in a group of dogs with histologically confirmed gall bladder disease. A total of 65 dogs were included. Branchlike, heterogeneous, and homogeneous contrast enhancement of echogenic intraluminal mass-forming lesions was a contrast-enhanced ultrasound characteristic of polypoid lesions due to cystic mucosal hyperplasia of the gallbladder and/or tumor, which had different wash-in and washout characteristics...

BACKGROUND AND AIM: Polypoid lesions of the gallbladder may be neoplastic or non-neoplastic. Correct diagnosis would help reduce unnecessary cholecystectomies. This study aimed to determine the predictive value of individual ultrasound characteristics for diagnosis of neoplastic polyps and to build a scoring system based on these characteristics. METHODS: A total of 109 patients with gallbladder polyps ≥ 6 mm underwent conventional ultrasound examination and received finally diagnosis by pathological examination...

Large cell neuroendocrine carcinoma (LCNEC) of the gallbladder is extremely rare and usually combined with other type of malignancy, mostly adenocarcinoma. We report an unusual case of combined adenosquamous carcinoma and LCNEC of the gallbladder in a 54-year-old woman. A radical cholecystectomy specimen revealed a 4.3×4.0 cm polypoid mass in the fundus with infiltration of adjacent liver parenchyma. Microscopically, the tumor consisted of two distinct components. Adenosquamous carcinoma was predominant and abrupt transition from adenocarcinoma to squamous cell carcinoma was observed...

REVIEW
Kumar Sandrasegaran, Christine O Menias
Biliary cancers include gallbladder cancer (GBC) and cholangiocarcinoma (CCA). GBC may appear as a mass replacing the gallbladder, thickened gallbladder wall, or polypoid lesion in the gallbladder. Gallbladder polyps with low risk of GBC (eg, 6- to 10-mm polyps without other risk factors) are screened with sonography. In general, polyps smaller than 5 mm are ignored and those larger than 10 mm require surgical consideration. Screening for CCA is less well-established. On imaging, CCA may be divided into mass-forming, periductal infiltrating, and intraductal types...

BACKGROUND AND STUDY AIMS: Gallbladder polyps (GBPs) are found in 5-7% of the adult population. However, it is very important to differentiate between benign and malignant polyps to establish an appropriate treatment. The present study aimed to determine the relevance of the 10-mm size criterion and attempted to determine the cut-off diameter of T1b tumours, which requires additional surgical intervention. PATIENTS AND METHODS: Cases with GBPs were collected between January 2005 and January 2015...

Gallbladder polypoid-lesions (GPs) are found in 5-10% of the general population. Although the majority of GPs are asymptomatic and benign in nature, some of them can develop into cancer, which carries a poor prognosis. Currently, the risk factors, natural history and classification of GPs remain unclear, differentiation of benign from malignant or premalignant GPs based on available diagnostic modalities and/or features of patients and GPs remain difficult, and there are still no evidence-based guidelines to dictate when and how GPs of varying sizes and subtypes should be managed...

BACKGROUND AND AIM: Gallbladder polypoid-lesions (GPs) are commonly seen on ultrasonography (USG), but several aspects of this problem are ill-defined. This study aimed to analyze clinic and pathologic characteristics of 1446 USG-detected GPs, identify predictive factors for cholesterol lesions and malignancy, and provide comments and recommendations on specific aspects of GPs. METHODS: We retrospectively analyzed clinic files of 1446 patients who underwent cholecystectomy for USG-detected GPs between 2008 and 2015 in Gallbladder Diseases Center, East Hospital of Tongji University...

INTRODUCTION:  Polypoid lesions of the gallbladder (PLG) are relatively common in adults, while they are very rare in children. The use of high-quality ultrasonography leads to increased detection of PLG, although less than 20 pediatric cases of primary PLG have been reported in the literature. The aim of this study was to address the experience of PLG management in children. MATERIALS AND METHODS:  A retrospective multicenter review of children with ultrasonographically defined PLG between 2006 and 2016 was performed...

BACKGROUND: With triphasic, dynamic contrast-enhanced CT scan to identify benign and malignant gallbladder polypoid lesions, we hope to determine an accurate diagnosis before surgery. STUDY DESIGN: Ninety patients with gallbladder polypoid lesions were treated surgically in the Department of Hepatobiliary Surgery, the First Affiliated Hospital of China Medical University, Shenyang, China, from July 2013 to July 2016, and divided into 2 groups according to postoperative pathologic results: a malignant group with 44 patients and a benign group with 46 patients...

Background: Gallbladder stone (GBS) is a common gastrointestinal disease that can progress to severe cholecystitis and is a strong risk factor for gallbladder cancer (GBC). The present study was conducted to evaluate region-specific causes of GBS which was proved as major risk factor for GBC in Jeju Island, Korea. Methods: Age and sex match case-control study was performed among 171 pairs of case and controls. The cases were patients who were diagnosed with GBS, had definite clinical symptoms, and underwent a cholecystectomy in Cheju Halla General Hospital, Jeju, Korea during 2010-2014...
