Paraganglioma-an unusual solitary nodule of the thyroid.

Extra-adrenal paraganglionic cells are histochemically non-chromaffin and are related to the parasympathetic system. Hence, in the head and neck region, paraganglioma are most commonly found in the carotid body, vagus nerve, jugulotympanic paraganglia and, occasionally, the superior and inferior paraganglia. Very rarely they may be found within the thyroid gland. 2–6 The authors describe an unusual case of an intrathyroidal paraganglioma, presenting as a thyroid solitary nodule.
