Sialoblastoma of the parotid gland

Abstract 

A 3 year-old girl presented with a 6- months history of facial swelling in the region of cheek. Physical examination revealed a firm, non-tender, non- erythematous, mobile, 3×3cm mass in the right cheek. Fine needle aspiration biopsy of the mass demonstrated significiant mitotic activity, slight pleomorfism and atypical cells. A transoral incisional biopsy was also done for accurate diagnosis and the tumor was diagnosed as sialoblastoma. After performing superficial parotidectomy, the tumor was excised with large margins. No adjuvant treatment was given and no recurrence has been noted after 6 months. Despite the rareness of the disease, pathologists and otolaryngologists should always consider the possibility of sialoblastoma of salivary glands in childhood and it can be best described as locally agressive with malignant potential.
