case_images: A neck Computed tomography angiography (CTA) demonstrated a carotid body tumor (3.8 cm x 2.5 cm x 3.3 cm) classified as Shamblin II and an intrathoracic multinodular thyroid gland with a right lobe extension of 11.9 cm x 9.7 cm and the left lobe of 25.2 cm x 21.3 cm with caudal retrosternal growth and evidence of slightly trachea deviation (Fig. 1).

case_images: A total thyroidectomy was performed with a transverse lower neck incision (Kocher incision), posteriorly, CBT was resected by an extension of the previous Kocher incision to the anterior border of the sternocleidomastoid muscle using the retrocarotid reported previously in our group as an effective technique, also two surrounding lymph nodes were resected to rule out malignancy (Fig. 2).
case_images: A) Thyroid follicles filled with colloids with variability in their size. (B-C glomus), B) Tumor nests separated by a fibrovascular septum (Zellballen), C) Eosinophilic cells with indistinct edges, round nucleus and chromatin with "salt and pepper" appearance.
