Primary renal adenosquamous carcinoma.
A case of renal adenosquamous carcinoma is presented. The fact that the urothelium has no glandular or squamous structures makes the pathogenesis of this tumor unique. The process is assumed to begin with urothelial metaplasia resulting from chronic irritation leading to dysplasia and subsequently squamous and glandular differentiation.
