Paratesticular tumors are rare, especially when they are metastatic. Most of them originate in the prostate, kidney, gastrointestinal tract, lung, and breast. The most common site of metastasis from the gastrointestinal tract is the colon. A 75-year-old male presented with a painless and tense right scrotal mass. He underwent a radical right orchiectomy, and the pathology revealed mucinous cystadenocarcinoma of the paratesticular tissue. Computed tomography revealed focal wall thickening at the rectosigmoid junction and liver nodules. The colonoscopic biopsy of the mass showed adenocarcinoma. Immunohistochemical staining of both sites confirmed the diagnosis of colorectal adenocarcinoma metastatic to the scrotum. 相似文献

Background
Primary intestinal NK/T cell lymphoma is rare but aggressive and exhibits a poor prognosis. Little is known about its clinical characteristics because few studies with small sample sizes have been reported.Aims
To provide clinicopathological features and endoscopic findings and to summarize the treatment outcomes of primary intestinal NK/T cell lymphoma to improve our understanding of this disease.Methods
Between January 2011 to December 2016, 13 patients with confirmed primary gastrointestinal NK/T cell lymphoma at our center were described, and an updated literature review was provided.Results
In this series of 13 cases, 69.23% were men, the median age was 39 years, and the median survival was 6 months. The common clinical manifestations included abdominal pain (76.92%) and gastrointestinal bleeding (46.15%). Lymphomas were common in the large intestine (69.23%). In 76.92% of patients, the clinical staging was stage I, and all 13 patients manifested ulcerative lesions and no tumor mass on endoscopy. The clinical characteristics of primary intestinal NK/T cell lymphomas were similar to results in existing literature.Conclusion
Intestinal NK/T cell lymphoma shows nonspecific clinical features and poor prognosis, which is mainly expressed as ulcers on endoscopy. Emergency surgery may be an adverse prognostic factor of lymphoma, since it is prone to progress toward gastrointestinal perforation. 相似文献70.
