Surface epithelial-stromal tumor - Wikipedia

Epithelial-stromal tumors are classified on the basis of the epithelial cell type, the relative amounts of epithelium and stroma, the presence of papillary processes, and the location of the epithelial elements. Microscopic pathological features determine whether a surface epithelial-stromal tumor is benign, a borderline tumor, or malignant (evidence of malignancy and stromal invasion).
