RESUMO
Clear cell renal cell carcinoma is the most common renal neoplasm in adults. It has a relatively slow growth pattern that delays diagnosis until the onset of local, paraneoplastic or metastasis-related manifestations, and an unpredictable behavior ranging from aggressive tumors with poor short-term prognosis to late recurrence cases where metastases are identified years after nephrectomy, the latter scenario being the subject of the case we herein report.

Nasopharynx metastases are an extremely rare cause of hepatocarcinoma debut. We report the case of a 71 year old man who presented symptoms of nosebleed and diplopia event, diagnosed by imaging and biopsy of ethmoidal metastasis of hepatocarcinoma.

We report the case of a 78-year-old woman with dyspepsia for several years and a history of cholecystectomy, informed by pathology as calculous cholecystopathy, where CT revealed a left-sided intrahepatic bile duct dilation. Cholangio-MRI confirmed a size increase in the distal intrahepatic bile duct on the left side, with T2-hyperintense contents with scarce contrast enhancement, which resulted in the observed dilation. . A Spybite® forceps was used to obtain a biopsy sample, which showed a benign papillary growth compatible with biliary papillomatosis. Biliary papillomatosis or intraductal papillary neoplasm of the biliary tract is a rare, uncommon condition characterized by intraductal papillary growth of the biliary epithelium. It has a tendency towards malignization, hence must be considered a premalignant condition . Major symptoms include jaundice, abdominal pain, and repeat cholangitis, with imaging studies being key for diagnostic suspicion . The development of cholangioscopy with biopsies allows an early diagnosis of malignant precursor lesions of the bile duct, thus allowing early treatment.

We report the case of a 62-year-old woman with no history of interest who presented with dyspepsia of 2 years' standing. Gastroscopy revealed a subepithelial lesion at the greater antral curvature with irregular surface and preserved mucosal and vascular pattern, 15 mm in diameter. Because of clinical persistence a radial endoscopic ultrasonogram (EUS) was performed, which showed a well-delimited hypoechoic lesion with heterogeneous areas that was dependent on the muscularis mucosae layer. A biopsy was obtained using the "bite-on-bite" technique, which provided no pathological findings. With these findings an endoscopic submucosal dissection (ESD) procedure was performed with wide margins and no complications. Pathology found low-grade mesenchymal fusicellular proliferation dependent on the muscularis mucosae with immunohistochemistry positive for smooth-muscle vimentin and actin, consistent with plexiform fibromyxoma.
