BACKGROUND AND AIM Most cases of Meckel's diverticula are asymptomatic, however, some cases presented with gastrointestinal (GI) bleeding. It is often difficult to determine whether Meckel's diverticulum is a source of obscure GI bleeding. Double balloon endoscopy allows endoscopic access to the entire small intestine. The aim of this study was to compare(More)
BACKGROUND Although renal cell carcinoma (RCC) is considered to be an immunogenic tumor, the role of immunogenicity in this tumor for predicting treatment response has been little investigated. PATIENTS AND METHODS Resected RCC specimens from 25 patients who received cytokine treatment for metastases were investigated using immunohistochemistry for CD83+(More)
Tamoxifen has been widely used in breast cancer treatment. In recent years, the occurrence of uterine malignancies in patients receiving long-term tamoxifen therapy has attracted attention. Most of these malignancies are endometrial adenocarcinomas, but low-grade endometrial stromal sarcomas have occasionally been reported. Here we report a woman who(More)
Patients with skin metastasis always had disseminated metastases in many organs. We herein report an unusual case with skin metastasis from small cell lung cancer (SCLC). The patient was treated with platinum-containing chemotherapy, and the response to the therapy was evaluated as partial response. The patient had slowly progressive disease and died of(More)
Cases of ossification and increased bone mineral density (BMD) at sites of bone metastasis following zoledronic acid (ZA) treatment have not been reported. The current study presents the case of a 65-year-old patient with lung adenocarcinoma and bone metastases in the lumbar vertebrae and femurs. Ossification and an increase in BMD at the metastatic sites(More)
Double balloon endoscopy (DBE) is useful for diagnosing many intestinal diseases and for endoscopic procedures. We report a case of chronic diarrhea in a 58-year-old Japanese man. He was initially suspected to have malabsorption syndrome. DBE showed reduction of folds, scalloping, mucosal nodularity and granularity. Pathological examinations of biopsies(More)
Complications in patients with systemic lupus erythematosus (SLE) can lead to mortality (1). A 54-year-old woman with an 18-year history of SLE was admitted because of abdominal pain, vomiting, diarrhea, and mental confusion. A physical examination revealed a late systolic murmur and mild abdominal distension. Her complete blood count showed mild anemia and(More)
Esophageal submucosal tumors are occasionally detected incidentally during a gastrointestinal survey. In the present study, a case of esophageal leiomyoma is reported, which was incidentally detected by chest radiography during an annual survey of mass-screening for lung cancer. The patient underwent a laparoscopic lower esophagectomy, a proximal(More)
A 33-year-old homosexual Japanese man who admitted to having sex with men presented with a two-week history of dyspnea and fever. Chest imaging showed diffuse pulmonary frosted-glass-like shadows. A blood test revealed positive HIV antibodies with a CD4 cell count of 66/μL. Bronchoalveolar lavage identified pneumocystis. Although the patient exhibited a(More)
