Renal angiomyolipomas are commonly associated with spontaneous hemorrhage which can be life-threatening and may require radical nephrectomy for control of hemorrhage. Transcatheter embolization was used in 2 cases of spontaneously bleeding angiomyolipomas; permanent control was achieved in 1 case and temporary control in the other. This more conservative approach was made possible by our ability to diagnose these benign renal tumors confidently using computed tomography.
The immunological specificity of prostatic acid phosphatase has been demonstrated previously in the laboratory and used in a small number of patients. Our findings in 96 patients using gel immunodiffusion with an acid phosphatase antiserum in the study of bone marrow aspirates and lymph nodes are reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
