Granular cell tumour of the larynx.
Granular cell tumour (GCT) of the larynx is an uncommon laryngeal tumour. It is always benign and commonly located in the posterior part of the larynx. Care must be taken to differentiate this lesion from others due to the presence of pseudo-epitheliomatous hyperplasia which overlies the GCT and may occasionally mimic squamous cell carcinoma. Therefore, histological differentiation is important because these tumours are normally managed conservatively. The origin of this tumour is a matter of debate, but most authors believe it to be neural in origin. The rarity of this tumour in the male population prompted reporting this case in the literature.
