[Carcinoma of the thyroid with the so-called "tall cells"]

Two tall-cell tumours were found in a group of 70 papillary thyroid carcinomas. The tall cells were all over the first tumour whereas in the second case they represented more than 40% of tumour cells. Both patients were followed 8 and 7 years respectively. Cervical lymph node metastases was mentioned in the clinical history of the first case. Biological behaviour of both tumours was not different at large from classical papillary carcinomas.
