Multiple Discordant Histology After Nephrectomy: Descriptive Analysis and Outcomes.

Background: While RCC is the most common primary renal neoplasm, few cases of ipsilateral renal lesions of different RCC histologic subtypes have been described. The objective of this study was to evaluate our experience with synchronous, histologically unique, primary renal neoplasms within the same kidney.

Patients And Methods: We retrospectively analyzed 2 institutional nephrectomy databases from 2000 to 2013.

Comparison of a combined nontreponemal (VDRL) and treponemal immunoblot to traditional nontreponemal and treponemal assays.

Background: Serology is the mainstay for the diagnosis and management of patients with syphilis. Newer technologies such as immunoblotting are now available for the diagnosis of syphilis.

Methods: A commercial IgM/IgG immunoblot assay that detects both nontreponemal (VDRL-Venereal Disease Research Laboratory) and treponemal antibodies was compared with standard nontreponemal and treponemal assays.
