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.

Diagnosis and treatment of parotid tumours.

Diagnosis and treatment of 51 cases of parotid tumour seen and treated in King Fahad National Guard Hospital, Riyadh, are discussed here. More emphasis is placed on proper clinical history and physical examination of patients with parotid lump because usually this will provide enough information to the clinician about the nature of the swelling. Imaging studies are helpful in supporting the clinical diagnosis and determining the extent of the lesion particularly in cases of malignant tumours. Fine needle aspiration biopsy needs an expert cytologist for salivary gland neoplasm and the need for proper communication between the surgeon and cytologist is stressed. All 51 cases underwent surgical excision which is the treatment of choice. Follow-up periods were variable and short.
