title: [Immunohistochemistry of thyroglobulin in the diagnosis of clear cell carcinomas of the cervical region].
abstract: 6 thyroid gland and 3 cervical lymph node clear-cells carcinomas are investigated by means of indirect immunofluorescence detection of thyroglobulin. Immunofluorescence was positive only in 1 case, which was a primitive thyroid carcinoma. In 7 other cases, its negativity pointed at the metastatic nature of the lesion, from a clear cell carcinoma of kidney (in 4 cases, nephrectomy was very remote, and in 3 cases, the renal lesion was discovered after our examination of the thyroid tumour). One observation showed negative staining reaction, and was a propagation of a parathyroid carcinoma to the thyroid gland. It is concluded that thyroglobulin can be used as an immunohistochemical marker to establish whether a clear cell cervical tumour originates from thyroid gland, or is a metastatic neoplasm.
