The diagnosis of thyroid nodules is straightforward and rarely mistaken. We present a case of a paraesophageal granular cell tumor, discovered incidentally during surgery for what it was diagnosed as a suspicious thyroid nodule by ultrasound and FNA. Complete resection was achieved without disruption of the esophageal mucosa. A terminal branch of the recurrent laryngeal nerve had to be resected en bloc with the tumor. Morphological and immunohistochemical diagnosis was established postoperatively. A review of the literature is presented.
