metanephric adenofibroma

A rare, benign biphasic (epithelial) and stroma (renal) lesion, in which the epithelial component is that of a metanephric adenoma: cellular, closely packed acini, scattered tubules, numerous solid areas, and occasional "glomeruloid bodies". The individual cells are small, with scant pale cytoplasm; calcospherites may be present.

Solid mixed epithelial and stromal tumors also need to be distinguished from mesoblastic nephroma and metanephric adenofibroma. Cystic nephroma in the pediatric age group is an entity entirely distinct from the adult tumors and is considered a fully differentiated nephroblastoma (Wilms tumor).
