Intralaryngotracheal thyroid--ectopic thyroid or invasive carcinoma?
Intralaryngotracheal thyroid is a rare clinical condition with only about 125 cases described so far in the literature. We present an unusual case of intralaryngotracheal thyroid which had many clinical features of malignancy and yet appeared benign on histology. As in this case, well-differentiated thyroid cancer can present with locally aggressive clinical features and can pose a dilemma in management if treatment decisions are guided solely by histological features.
