RESUMEN
BACKGROUND: Esophageal metastasis of renal cell carcinoma (RCC) is extremely rare. We have described herein a case of a 59-year-old man with esophageal metastasis of RCC that was endoscopically resected. CASE PRESENTATION: The case was a 59-year-old man who had undergone left nephrectomy for renal clear cell carcinoma 17 years ago and splenectomy for splenic metastasis 3 years ago. Esophagogastroduodenoscopy (EGD) performed 9 years ago revealed a small reddish elevated lesion with a smooth surface in the middle esophagus; this lesion increased in size 4 years ago. However, no biopsy was performed. The lesion continued to grow in size and was found to have become nodular during the present observation. Biopsy revealed clear cell carcinoma. Endoscopic ultrasound (EUS) revealed that the lesion had not invaded the submucosa, and contrast-enhanced computed tomography did not reveal any other metastasis. The lesion was successfully removed en bloc via endoscopic submucosal dissection (ESD). Pathologically, the tumor was detected in the subepithelium with focal infiltration of the muscularis mucosa. It consisted of monotonous cells with small nuclei and a clear cytoplasm. Immunohistological findings indicated that the tumor was a metastasis of RCC. The lateral and vertical margins were noted to be free. CONCLUSIONS: We have presented herein a case of esophageal metastasis of RCC that had progressed over 9 years and was then resected en bloc through endoscopic submucosal dissection.

A man in his fifties had a medical checkup. Mucosal papillomatosis in his oral cavity and palmoplantar keratosis were observed. Esophagogastroduodenoscopy revealed multiple polypoid lesions both in the esophagus and stomach. In addition, colonoscopy showed schwannoma in the rectum. He underwent an operation for adenomatous goiter. At first his typical esophageal multiple polypoid lesion was a diagnostic cue to Cowden disease (CD). Other clinical findings convinced us that he was suffering from CD. He was, then, diagnosed as CD according to the criteria of International Cowden Consortium although he had no family medical history suspicious of CD. Interestingly, genetic testing revealed that the patient had a germline mutation in exon5 of PTEN on chromosome 10. It was a point mutation of C to T transition at codon130, resulting in nonsense mutation (CGAâTGA). A close follow-up, especially cancer surveillance, is necessary for him since CD is associated with a high risk of developing malignant disease. It is noted that the typical esophageal features can be a diagnostic cue to CD, as shown in the present case.

Case reports of protein-losing gastroenteropathy (PLGE) associated with not only mixed connective tissue disease (MCTD) but also Sjögren syndrome (SjS) are very rare. We report a first case of PLGE in a patient with both MCTD and SjS. A 58-year-old Japanese woman was referred and admitted to our hospital because of abdominal fullness and lower leg edema. Her past medical history revealed SjS at age 40. Physical examination demonstrated lower leg edema and Raynaud's phenomenon. Blood chemistry data showed severe hypoproteinemia. Anti RNP antibody was positive. MCTD was diagnosed. The alpha-1 antitrypsin clearance level was high. The (99m)Tc-DTPA human serum albumin scintigraphy demonstrated abnormal accumulation in the intestine. PLGE associated with both MCTD and SjS was diagnosed, but she was successfully treated by prednisolone.

BACKGROUND/AIMS: Antithrombotic/nonsteroidal antiinflammatory drug (NSAID) therapies increase the incidence of upper gastrointestinal bleeding. The features of hemorrhagic peptic ulcer disease in patients receiving antithrombotic/NSAID therapies were investigated. METHODS: We investigated the medical records of 485 consecutive patients who underwent esophagogastroduodenoscopy and were diagnosed with hemorrhagic gastroduodenal ulcers. The patients treated with antithrombotic agents/NSAIDs were categorized as the antithrombotic therapy (AT) group (n=213). The patients who were not treated with antithrombotics/NSAIDs were categorized as the control (C) group (n=263). The clinical characteristics were compared between the groups. RESULTS: The patients in the AT group were significantly older than those in the C group (p<0.0001). The hemoglobin levels before/without transfusion were significantly lower in the AT group (8.24±2.41 g/dL) than in the C group (9.44±2.95 g/dL) (p<0.0001). After adjusting for age, the difference in the hemoglobin levels between the two groups remained significant (p=0.0334). The transfusion rates were significantly higher in the AT group than in the C group (p=0.0002). However, the outcome of endoscopic hemostasis was similar in the AT and C groups. CONCLUSIONS: Patients with hemorrhagic peptic ulcers receiving antithrombotic/NSAID therapies were exposed to a greater risk of severe bleeding that required transfusion but were still treatable by endoscopy.
