Atypical cribriform lesions of the prostate: Clinical significance, differential diagnosis and current concept of intraductal carcinoma of the prostate.
Atypical cribriform lesions of the prostate gland represent cribriform “high-grade prostatic intraepithelial neoplasia” (HGPIN) or “intraductal carcinoma of the prostate” […]

Clinical Applications of Novel ERG Immunohistochemistry in Prostate Cancer Diagnosis and Management
Immunohistochemical (IHC) staining for ERG is utilized as a surrogate for TMPRSS2: ERG gene fusions, a specific molecular event seen […]
Carcinoma of the Collecting Ducts of Bellini and Renal Medullary Carcinoma: Clinicopathologic Analysis of 52 Cases of Rare Aggressive Subtypes of Renal Cell Carcinoma With a Focus on Their Interrelationship
Carcinoma of the collecting ducts of Bellini and renal medullary carcinoma are rare aggressive renal tumors. First described in 1949, […]
Predictive Value of ERG Oncoprotein Expression and Pathologic Parameters In the Stratification of Prostate Cancer Risk Associated With High Grade Prostatic Intraepithelial Neoplasia (HGPIN) Diagnosis In Prostate Needle Biopsy
