Light micrograph of an ovarian gonadoblastoma. Cells with small round, dark nuclei resemble immature Sertoli cells and are arrayed around spherical collections of eosinophilic material. Larger seminoma-like cells with clear cytoplasm are scattered about in the lower half of the field. The arrowhead points to a calcification that is typical of this neoplasm.
