In contrast to the common finding of mucin secretion in non-endocrine epithelial tumors, in endocrine tumors it is a very rare finding. Mucin secretion is very rare among the thyroid tumors. In the studies carried out on classifying the thyroid carcinomas in recent years, it was reported that the mucin might be secreted in thyroid carcinomas. In this paper, we present a rarely-seen follicular variant of papillary carcinoma secreting mucin.
