Background:
Granular cell tumour (Abrikossoff's tumour) was first described by Abrikossoff in 1926. These tumours are rare and usually presents as a solitary lesion, located mainly in the subcutaneous tissue of the head and neck, and in the oral cavity (tongue).
Case Report:
We report a rare case of a granular cell tumor of the parotid gland, in a 55-year old woman, who was referred with a left preauricular mass that had rapidly increased in size over 2 months. There was no cervical lymph adenopathy. RMI demonstrated a solitary lesion of the parotid gland. Surgical resection was performed.
Conclusion:
We discuss the classification, pathophysiology and the treatment of granular cell tumours through a review of the literature.
