Mixed XXXX of the thyroid: a case report.

@entity3557 @entity1377 @entity1 @entity5 @entity8703 @entity189 @entity5651 @entity259 @entity1374
With fewer than 40 cases described in the otolaryngology literature, mixed @entity3557 represents a rare but phenotypically distinct @entity5 . While isolated @entity189 may be admixed with normal follicular structures, true mixed @entity189 morphological and immunological characteristics of medullary and @entity1377 within a single lesion. We report the case of a 73-year old @entity1 initially evaluated for a multinodular @entity5651 . The @entity1 denied a family history of @entity259 or other @entity8703 . Fine needle aspiration of a nodule of the thyroid isthmus suggested a @entity5 with abundant Hurthle cells and colloid present. Considering these findings, the @entity1 underwent a left thyroid lobectomy with isthmusectomy. Histopathological analysis of the surgical specimen revealed a @entity259 measuring 0.4 cm in size. Within this lesion, a distinct focus of @entity3557 , follicular variant, measuring 0.1 cm was also identified. Mixed @entity3557 is a rare clinical entity but merits consideration in the differential diagnosis of thyroid nodules particularly in @entity1 with a family history of @entity1374 . The foundation of treatment of this lesion is total thyroidectomy with central compartment node dissection in the clinically N0 neck and dissection of levels II-VII in the node-positive neck.
