[Neurilemmoma of the esophagus imitating carcinoma of the thyroid isthmus].
Fine needle aspiration cytology of a "stone hard" nodule in isthmic thyroid region of a 56-year old woman yielded unusual spindle and polyploid cells in a relatively monomorphic inflammatory background. Finding was suspicious of malignancy. Differential diagnosis of reparative inflammatory changes, anaplastic or medullary carcinoma was considered. During the operation a tight connection of the tumour with oesophageal wall as well as with thyroid was discovered. Biopsy proved the tumour to be a neurilemmoma originating in the oesophageal wall. Most of the tumour cells were S-100 protein positive. Comparison of the cytologic smears and biopsy slides proved the unusual cells to be of tumour origin.
