dc.description.abstract | Mixed medullary‐follicular carcinoma (MMFC) of thyroid is an extremely rare tumor, characterized by coexistence of morphological and immunohistochemical features of both medullary carcinoma and follicular (or papillary) carcinoma. We herein present fine needle aspiration (FNA) findings of a histology‐confirmed MMFC along with a review of literature. The patient was a 64‐year‐old woman who had a history of Hashimoto's thyroiditis and presented with enlargement of preexisting right thyroid nodule. An US‐guided FNA of the thyroid nodule was performed and conventional smears were prepared. A cytologic diagnosis of “positive for malignancy, consistent with medullary thyroid carcinoma (MTC)” was rendered based on the presence of features characteristic for MTC, and the absence of components of follicular neoplasm (adenoma and carcinoma) or papillary carcinoma. However, microscopic examination of the follow‐up total thyroidectomy specimen with the aid of immunocytochemical study detected minor portion of follicular carcinoma in addition to MTC. A histologic diagnosis of MMFC was then established. While specific identification of MMFC by FNA may be difficult, it should be emphasized that adequate sampling in conjunction with the proper immunostaining panel could have highlighted the different aspects of the mixed tumor.
