case_images: Contrast-enhaced cervical computed tomography: axial (A), coronal (B) and sagittal view (C): tumoral lesion between the left thyroid lobe, the left edge of the subglottic area of the larynx and the first tracheal ring filling all the lumen. The origin could be either the thyroA d gland or the larynx

case_images: This process measures 34*25*50mm it respects the vocal cords and the arytenoids but invades the cricoid cartilage (Figure 1).
case_images: Endscopic view of the larynx showing a subglottic obstructive tumor which respects the arytenoids, the vocal folds and the hypopharynx

case_images: The patient underwent panendoscopy under general anesthesia that shows the obstructive subglottic extension of the tumor with respect of the arytenoids and the hypopharynx (Figure 2).
case_images: (A) cribriform growth pattern displaying several prominent pseudocysts surrounded by basaloid cells with hyperchromatic angulated nuclei (hematoxylin-eosin, x200); (B) low power view displaying the invasion of the muscle (hematowylin-eosin x100)
