Case Reports[How to treat a thyroid adenocarcinoma inside a branchial cyst].
The authors reported three cases of branchial cycts containing a thyroid adenocarcinoma. This rare condition imposed a search for the primary tumor. ⋯ Histological examination of the operative specimen after total blocking in paraffin helped discover microscopic foci of papillary carcinoma in the thyroid gland. These data justified this therapeutic attitude because the nature of the adenocarcinoma found in the branchial cyst is likely to be metastatic.
