106. Loss of Fnip1 alters kidney developmental transcriptional program and synergizes with TSC1 loss to promote mTORC1 activation and renal cyst formation. Full Text available with Trip Pro

Loss of Fnip1 alters kidney developmental transcriptional program and synergizes with TSC1 loss to promote mTORC1 activation and renal cyst formation. Birt-Hogg-Dube' Syndrome (BHDS) is a rare genetic disorder in humans characterized by skin hamartomas, lung cysts, pneumothorax, and increased risk of renal tumors. BHDS is caused by mutations in the BHD gene, which encodes for Folliculin, a cytoplasmic adapter protein that binds to Folliculin interacting proteins-1 and -2 (Fnip1, Fnip2) as well (...) as the master energy sensor AMP kinase (AMPK). Whereas kidney-specific deletion of the Bhd gene in mice is known to result in polycystic kidney disease (PKD) and renal cell carcinoma, the roles of Fnip1 in renal cell development and function are unclear. In this study, we utilized mice with constitutive deletion of the Fnip1 gene to show that the loss of Fnip1 is sufficient to result in renal cyst formation, which was characterized by decreased AMPK activation, increased mTOR activation, and metabolic

108. Preoperative next-generation sequencing of pancreatic cyst fluid is highly accurate in cyst classification and detection of advanced neoplasia. Full Text available with Trip Pro

Preoperative next-generation sequencing of pancreatic cyst fluid is highly accurate in cyst classification and detection of advanced neoplasia. DNA-based testing of pancreatic cyst fluid (PCF) is a useful adjunct to the evaluation of pancreatic cysts (PCs). Mutations in KRAS/GNAS are highly specific for intraductal papillary mucinous neoplasms (IPMNs) and mucinous cystic neoplasms (MCNs), while TP53/PIK3CA/PTEN alterations are associated with advanced neoplasia. A prospective study

109. Differential diagnosis of periapical cyst using collagen birefringence pattern of the cyst wall Full Text available with Trip Pro

Differential diagnosis of periapical cyst using collagen birefringence pattern of the cyst wall Periapical lesions, including periapical cyst (PC), periapical granuloma (PG), and periapical abscess (PA), are frequently affected by chemical/physical damage during root canal treatment or severe bacterial infection, and thus, the differential diagnosis of periapical lesions may be difficult due to the presence of severe inflammatory reaction. The aim of this study was to make differential (...) , palisading pattern but no continuous band-like pattern. The linear band-like birefringence in PC was ascribed to pre-existing expansile tensile stress of the cyst wall.In this study all PCs (n = 122) were distinguishable from PGs and PAs by their characteristic birefringence, despite the absence of lining epithelium (n = 20). Therefore, the authors suggest that the presence of linear band-like collagen birefringence of the cyst wall aids the diagnostic differentiation of PC from PG and PA.

110. A Wandering Abdominal Mass in a Neonate: An Enteric Duplication Cyst Mimicking an Ovarian Cyst Full Text available with Trip Pro

A Wandering Abdominal Mass in a Neonate: An Enteric Duplication Cyst Mimicking an Ovarian Cyst Enteric duplication cysts are rare congenital anomalies that are prenatally diagnosed through antenatal ultrasonography (US). In female patients, however, attention must be paid since these formations might be confused with ovarian cysts. Herein, we present a case of a low birth weight female infant with an enteric duplication cyst. A cystic lesion was detected in the right abdomen of the fetus (...) on antenatal US and magnetic resonance imaging (MRI). Serial US and MRI examinations performed after birth showed a single cyst that wandered from side to side in the abdomen; the initial diagnosis was thought to be an ovarian cyst. During laparotomy, however, it was found to be an enteric duplication cyst with volvulus. To our knowledge, there has been no report of an enteric duplication cyst presenting as a wandering abdominal mass. Our experience indicates that early intervention is necessary

111. Differentiation of Pancreatic Cyst Types by Analysis of Rheological Behavior of Pancreatic Cyst Fluid Full Text available with Trip Pro

Differentiation of Pancreatic Cyst Types by Analysis of Rheological Behavior of Pancreatic Cyst Fluid Differentiation between mucinous and non-mucinous pancreatic cysts is exceedingly important and challenging, particularly as the former bears malignant transformation potential. Pancreatic cyst fluid (PCF)-based diagnostics, including analyses of biochemical markers, as well as cytology, has shown inadequate accuracy. Herein, a preliminary single-center study of 22 PCF samples, collected (...) by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA), assessed the rheological behavior of PCF and its correlation with lesion type. The dependence of PCF shear viscosity on shear rate was found to follow a power law and could be fitted using Ostwald-de Waele model. Three types of flow curves were identified, where two types correlated with non-mucinous cysts, differing by their power law exponent, and the third type corresponding to mucinous cysts. Viscosity measured at a high shear rate

113. Ligamentum flavum cyst: An uncommon but recognizable and surgically correctable category of juxtafacet cyst Full Text available with Trip Pro

Ligamentum flavum cyst: An uncommon but recognizable and surgically correctable category of juxtafacet cyst Ligamentum flavum cyst is considered as a category of juxtafacet cyst and is recognized to be rare cause of cord compression and radiculopathy. The pathogenesis of these cysts is not yet fully understood, but it has been proposed that continuous stress to this ligament due to minor repetitive trauma, such as in spondylolisthesis and degenerative disc disease, may lead to the development (...) of cyst. Intraspinal cyst can encroach and displace neural structures that can lead to neurologic symptoms. Although a rare entity, intraspinal cyst should be included in the causative factors of neurogenic claudication or lumbar radiculopathy based on typical magnetic resonance imaging appearance. Timely diagnosis is also imperative in this condition due to a better surgical outcome.

Computed Tomography (CT) Findings of Pulmonary Hydatid Cysts in Children and the Factors Related to Cyst Rupture BACKGROUND The lungs are the most common site of hydatid cysts in children. Rupture is the main complication of cysts causing morbidity and mortality. In this study we aimed to comprehensively describe the CT signs for cysts and analyze the relationship of cyst ruptures to the diameter and location of cyst. MATERIAL AND METHODS A total of 145 cysts from 102 patients, aged 17 years (...) or younger, who underwent a multi-detector computed tomography (MDCT) evaluation and had surgically proven pulmonary hydatid disease were included retrospectively. The CT images were analyzed for radiologic findings and signs of cyst rupture. RESULTS The cysts had a mean diameter of 5.45±3.03 cm. Most of the patients had a solitary cyst (70.6%). The most common lobes involved were the lower lobes (58.6%). Peripherally located cysts were more common than central cysts. The overall number of ruptured cysts

120. The clinical, histological and immunohistochemical characteristics and nomenclature of meibomian gland ductal cysts (intratarsal keratinous cysts) and eyelid steatocystomas Full Text available with Trip Pro

The clinical, histological and immunohistochemical characteristics and nomenclature of meibomian gland ductal cysts (intratarsal keratinous cysts) and eyelid steatocystomas PurposeMeibomian gland ductal cysts (MGDCs) and steatocystomas are epithelial lined, keratin-containing lesions of the eyelids. MDGCs are variably called tarsal keratinous cysts, intratarsal keratinous cysts of the meibomian glands, intratarsal inclusion cysts, epidermal cysts and epidermoid cysts. Both lesions are poorly (...) and are firm, well-circumscribed and non-tender, and sometimes the keratin-filled cyst protrudes visibly under the tarsal conjunctiva. Two cases were previously misdiagnosed as chalazia but recurred after incision and curettage. Histologically, these lesions are lined by squamous epithelium but lack a well-formed stratum granulosum and can be distinguished by their immunohistochemical staining characteristics. Complete excision, including a wedge of underlying tarsal plate for MDGCs, is curative
