Magnetic resonance imaging of the neck after paramagnetic contrast enhancement.. A laryngeal tumor (arrow) (30x20x22 mm) with no invasion of the surrounding structures. MRI (a) axial (T1W1 sequence), (b) axial (T1W1 sequence with fat-sat), (c) axial (T2W1 sequence), and (d) sagittal (T1W1 sequence).

FIG1
No invasion or infiltration of surrounding structures was recorded (Figures 1a-1d).
Histopathological examination of the patient.. (a) Glandular formations are visible (H&E stain, 200x). In MEC, three following neoplastic cell types are characteristic: epidermoid, mucous, and intermediate, with the latter prevailing in high-grade cases. (b) Mucous cells are highlighted (arrow; PAS histochemical stain, 200x).. PAS: periodic acid-Schiff; MEC: mucoepidermoid carcinoma

FIG2
The patient underwent a panendoscopy under general anesthesia, and biopsies indicated an intermediate-grade mucoepidermoid carcinoma of the left laryngeal ventricle (Figures 2a, 2b).
Surgical specimen with a large submucosal mass in the left laryngeal ventricle.

FIG3
The multidisciplinary team of our institution recommended a total laryngectomy due to the location and the histopathologic characteristics of the tumor (Figure 3).
