RESUMO
A 66 year old woman with end-stage renal disease and liver cirrhosis due to chronic hepatitis C virus infection was introduced to hemodialysis therapy in 2003. In 2007, hepatocellular carcinoma was identified and the patient underwent radio frequency ablation (RFA) and ethanol injection therapy (EIT) under laparotomy. A large vaginal tumor was incidentally found at gynecological examination. Histological diagnosis was diffuse large B-cell lymphoma (Stage IE). During the first course of chemotherapy, the vaginal tumor began to prolapse from the vaginal wall due to an excellent response to the chemotherapy and finally was resected. The patient received another course of chemotherapy followed by radiotherapy. The vaginal tumor was undetectable in the follow-up imaging studies. Although patients with end-stage renal disease are at increased risk for several cancers, the occurrence of malignant lymphoma following hepatocellular carcinoma is rare. Furthermore, lymphomas arising from the female genital tract are very uncommon.

A 63-year-old man on long-term hemodialysis therapy was hospitalized due to right lower abdominal pain. CT scan demonstrated a multiple concentric structure in the ileocecal region. Colonoscopy showed a polyp-like tumor arising from the expected location of the appendix, with a dimple at the top. Barium enema study revealed a submucosal tumor-like filling defect in the cecum with non-filling of the appendix. A diagnosis of intussusception of the appendix (IA) was made. During the follow-up, IA reduced spontaneously. The present case report is the first description of IA in a patient on hemodialysis therapy. Furthermore, spontaneous reduction of IA is indeed rare.
