Abstract:
Solitary Fibrous tumor is usually arising in the pleura of the thoracic cavity and it has been described in a variety of extrapleural sites including the abdominal cavity, soft tissue, upper respiratory tract and rarely in head and neck region. We experienced a rare case of solitary fibrous tumor in the parotid gland. A 49-year-old woman presented with a painless mass in the left parotid. The mass was well-demarcated and easily dissected, and it showed a patternless arrangement of potential malignant spindle cells in a fibrotic background and prominent vascular structures. In immunochemistry, the mass cells were positive for CD34, vimentin, and negative for actin, S-100 protein, and cytokeratins. Therefore, the parotid mass diagnosed as SFT. During the 24 months of follow-up, there was no recurrence of tumor growth.
