#1
Jared M Goldfarb, David Goldfarb, Marc R Rosen
PURPOSE OF REVIEW: The inferior turbinates are routinely examined by otolaryngologists on anterior rhinoscopy and nasal endoscopy. Most lesions of the inferior turbinate are benign but can often be confused with malignancy. This review highlights the broad differential of nonmalignant lesions of the inferior turbinates and their management. RECENT FINDINGS: A variety of infectious, inflammatory, neoplastic, and vascular lesions may affect the inferior turbinates...

BACKGROUND & AIMS: Prostaglandin E2 (PGE2) is mediator of inflammation that regulates tissue regeneration, but its continual activation has been associated with carcinogenesis. Little is known about factors in the PGE2 signaling pathway that contribute to tumor formation. We investigated whether yes associated protein 1 (YAP1), a transcriptional co-activator in the Hippo signaling pathway, mediates PGE2 function. METHODS: DLD-1 and SW480 colon cancer cell lines were transfected with vectors expressing transgenes or small hairpin RNAs and incubated with recombinant PGE2, with or without pharmacologic inhibitors of signaling proteins, and analyzed by immunoblot, immunofluorescence, quantitative reverse transcription PCR, transcriptional reporter, and proliferation assays...

BACKGROUND: To compare resectoscopic and small-diameter hysteroscopic techniques for endometrial polypectomy in patients with "unfavorable" cervix. METHODS: Eighty women with a single 2-4 cm sized endometrial polyp, with unfavorable cervical anatomical conditions were enrolled in the study. Forty patients were treated with a 26F resectoscope requiring cervical dilatation (group A), forty patients were treated with a 5-mm hysteroscope requiring vaginoscopic approach (group B)...

Gastric fundic gland polyps (FGPs) are common non-adenomatous gastric polyps arising from normal fundic mucosa without Helicobacter pylori (H. pylori) infection. Although systemic FGPs associated with familial adenomatous polyposis (FAP) often have dysplasia, there are few reports of dysplasia occurring in sporadic FGPs, especially when detected by magnifying endoscopy with narrow band imaging (ME-NBI). We experienced two cases of adenocarcinoma occurring in sporadic FGPs, and their ME-NBI findings were very useful for differentiating FGP with cancer from non-dysplastic FGP...

RATIONALE: Cholesterol polyps are rare in the common bile duct and difficult to diagnose. PATIENT CONCERNS: The small polypoid lesions often go undetected when using routine imaging methods, such as ultrasonography. DIAGNOSES: We treated a patient with cholesterol polyps in the common bile duct. After failing to detect choleliths using ultrasonography, magnetic resonance cholangiopancreatography revealed mild dilation of the common bile duct...

We report a case of two peculiar gallbladder polyps in a sixty-four year old male who presented with symptomatic cholelithiasis. Cholecystectomy was performed, which revealed two polyps measuring 0.6 cm and 1.9 cm, located in the body of the gallbladder. Microscopic examination of the polyps showed composite mesenchymal lesions with vascular proliferation of small-to-medium sized arterioles, myoid stroma, and lipomatous periphery. The myoid component was characterized by wisps of bland smooth muscle fibers loosely separated by proteinaceous and focally myxoid matrix...

Comparative efforts to understand the body plan evolution of stalked jellyfishes are scarce. Most characters, and particularly internal anatomy, have neither been explored for the class Staurozoa, nor broadly applied in its taxonomy and classification. Recently, a molecular phylogenetic hypothesis was derived for Staurozoa, allowing for the first broad histological comparative study of staurozoan taxa. This study uses comparative histology to describe the body plans of nine staurozoan species, inferring functional and evolutionary aspects of internal morphology based on the current phylogeny of Staurozoa...

Due to the rising prevalence of coronary heart disease, endoscopists are more frequently performing a polypectomy in patients on antiplatelet therapy (APT) and dual antiplatelet therapy (DATP). Despite the availability of several guidelines with regard to the management of antiplatelet drugs during the periprocedure period, there is still variability in the current clinical practice. This may be influenced by the low quality of the evidence supporting recommendations, because most of the studies dealing with APT and polypectomy are observational and retrospective, and include mainly small (< 10 mm) polyps...

BACKGROUND: Polypoidal choroidal vasculopathy (PCV) is characterized by the presence of polyps with or without a branching vascular network and more prevalent among Asians. The aim of this study was to compare the outcomes of conbercept therapy between two different angiographic subtypes of PCV. METHODS: Fifty-eight patients of PCV were classified into two phenotypes according to indocyanine green angiography (ICGA). In Type 1, both feeder and draining vessels are visible on ICGA and network vessels are numerous...

BACKGROUND: Classification schemes for differentiation of conventional colorectal adenomas from serrated lesions rely on patterns of blood vessels and pits. Morphologic features have not been validated as predictors of histology. AIM: Describe the prevalence of the "valley sign" and validate it as a marker of conventional adenomas METHODS: Three experts judged the prevalence of the valley sign in 301 consecutive small adenomas. Medical students were taught to recognize the valley and tested on their recognition of the valley sign...

BACKGROUND: Mucous retention cyst refers to a cyst made by expansion due to the blockage of the salivary gland near the maxillary sinus, and it is surrounded by epithelial cells. Most of them are small; therefore, they cannot be found well and are frequently with antral polyp. The aim of this study was to evaluate the clinical prognosis of sinus bone graft in patients with mucous retention cyst. METHODS: This study was performed retrospectively on 23 patients who had sinus bone graft...

Gastrointestinal xanthomas are infrequent non-neoplastic lesions characterized by the accumulation of foam cells in the lamina propria. They are commonly seen in association with dyslipidemia, chemotherapy or radiotherapy, and infections in immunosuppressed patients. However, no clear connection to hyperlipidemia has been found. They occur more frequently in the stomach, and are very rare in the small bowel and esophagus. We identified all cases of non-gastric xanthoma or xanthomatosis reported in the English literature by searching the PubMed database and retrospectively reviewed the clinical, endoscopic, and histopathologic features of the 11 cases of non-gastric gastrointestinal xanthomas diagnosed in our hospital...

Cowden Syndrome (CS) is an uncommon autosomal dominant multiorgan/system genodermatosis. It is characterized by the development of multiple hamartomas of endodermal, mesodermal and ectodermal origin, an increased lifetime risk of breast, thyroid, endometrial, and other cancers and an identifiable germline mutation. Mucocutaneous hamartomas are the most common lesions seen and mainly include facial trichilemmomas, oral mucosal papillomas, and benign acral keratoses. Herein, we report a case of a 63-year-old Caucasian male with a long-established diagnosis of CS and history of thyroid cancer, colonic polyps, and innumerable trichilemmomas, seborrheic keratoses, squamous papillomas, and non-melanoma skin cancers excised in the past...

Colorectal follicular lymphomas, primary or secondary, are rare. Magnifying endoscopy with narrow-band imaging is useful in the diagnosis of colorectal follicular lymphoma. In addition, immunohistochemistry is essential in differentiating follicular lymphoma cells from lymphoid follicle hyperplasia based on the presence of Bcl-2 expression. We herein report a rare case of follicular lymphoma of the caecum, presenting as a small polyp that was resected endoscopically.

PURPOSE: We evaluated all PET/CTs acquired for patients without a primary diagnosis of colorectal cancer, and compared results for those who had subsequent colonoscopy within 6 months, to assess the accuracy of FDG PET/CT for detection of incidental pre-malignant polyps and malignant colon cancers. MATERIALS AND METHODS: Medical records of 9,545 patients who underwent F-18 FDG PET/CT studies over 3.5 years were retrospectively reviewed. Due to pre-existing diagnosis of colorectal cancer, 818 patients were excluded...
