Figure 1 Cribriform-morular variant of papillary carcinoma. (A) Tumor consists of empty cribriform spaces adjacent to focal squamous morules. (B) Cribriform spaces are formed by bridges 1–2 cells wide. Nuclei of malignant cells are oval, pale, and grooved. (C) Microscopic cribriform-morular papillary carcinoma. Even small foci of carcinoma, approximately 0.1 cm, exhibit histologic features of the cribriform-morular variant of papillary carcinoma (hematoxylin-eosin stain).
