From: Primary pulmonary adenocarcinoma mimicking papillary thyroid carcinoma
Hematoxylin and eosin staining revealed that the eosinophilic and amorphous colloid-like luminal content showed scalloped border in the glandular cavity, pseudo-inclusions in the tumor cell nuclei or ground glass nuclei were evident in pulmonary tumor tissue (A, ×400; B, ×400) and metastasis lymph node (C, ×200; D, ×400). The intranuclear groove in the tumor cell nuclei was evident in metastasis lymph node (D, ×400).
