摘要
One thousand and sixty cases of thyroid carcinoma were reviewed to compare morules with squamous metaplasia clinicopathologically and immunohistochemically. Morules and squamous metaplasia were found in five (0.47%) and 32 cases (3.0%) respectively, The five patients with morules were all female (age 20-36 years) including four with papillary carcinoma and one with follicular carcinoma, The 32 patients with squamous metaplasia consisted of 30 females and 2 males (age 14-78 years), all of whom had papillary carcinoma except for one follicular carcinoma. The morules demonstrated characteristic 'optically clear nuclei' (OCN), which ultrastructurally showed filamentous structures in the nuclei. The OCN were immunohistochemically demonstrated to contain intranuclear biotin. Furthermore, the morule often accompanied with the OCN was positive for Ulex Europaeus agglutinin I (UEA-I) but negative for bovine muzzle epidermal keratin (EK). On the contrary, squamous metaplasia unaccompanied with the OCN was negative for UEA-I, but positive for EK. Follow-up information revealed that one of the five patients with morules had died of the disease, one was alive with pulmonary metastasis, and three were disease-free, Eight of 32 patients with squamous metaplasia had died of the disease; of the others who were alive, four patients have had recurrence.
