The patient was a 48\u2010year\u2010old woman. A 2\u2010cm mass was incidentally detected in the left lobe of the liver by abdominal computed tomography (CT) scan. Partial liver resection was performed for diagnosis and treatment. Histologically, the liver nodule was composed of small\u2010to\u2010large follicles containing colloid material. The lining epithelium was flat or cuboidal and showed no cellular or nuclear atypia. Immunohistochemical studies for thyroid\u2010specific proteins, thyroglobulin (Tg), triiodothyronine (T3) and thyroxine (T4), suggested that the nodule was of thyroid origin. Therefore, a differential diagnosis of metastasis of well\u2010differentiated thyroid cancer, ectopic thyroid tissue and teratoma was made. The patient had a history of subtotal thyroidectomy performed 8 years ago due to a thyroid tumor. The original surgical specimens of the thyroid tumor were diagnosed as follicular adenoma. Additional sections of the specimen were reviewed and an area of convincing vascular invasion was found that was suggestive of follicular carcinoma. Subsequent whole\u2010body examination failed to find other metastases. It was determined that the liver tumor was metastasized from well\u2010differentiated follicular carcinoma of the thyroid.<\/jats:p>","DOI":"10.1046\/j.1440-1827.2000.01065.x","type":"journal-article","created":{"date-parts":[[2003,3,12]],"date-time":"2003-03-12T17:14:50Z","timestamp":1047489290000},"page":"509-513","source":"Crossref","is-referenced-by-count":27,"title":["Incidentally detected liver metastasis of well\u2010differentiated follicular carcinoma of the thyroid, mimicking ectopic thyroid"],"prefix":"10.1111","volume":"50","author":[{"given":"Tetsuo","family":"Kondo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryohei","family":"Katoh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kosaku","family":"Omata","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshio","family":"Oyama","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akiharu","family":"Yagawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akira","family":"Kawaoi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2001,12,25]]},"reference":[{"key":"e_1_2_6_2_2","first-page":"493","volume-title":"Ackerman\u2019s Surgical Pathology.","author":"Rosai J.","year":"1996"},{"key":"e_1_2_6_3_2","first-page":"84","volume-title":"Tumors of the Thyroid Glands.
