Abstract

Solitary fibrous tumor, a mesenchymal neoplasm that arises most commonly from the pleura of the lung, 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 present a rare case of solitary fibrous tumor that occurred in the sublingual gland. A 52-year old woman presented with a painless mass in the left side of the floor of mouth. The tumor was well-demarcated and easily dissected, and it showed highly cellular areas of spindle cells with pattern-less architecture alternating with hypocellular areas. The tumor cells were positive for CD34 but negative for cytokeratins and S-100 protein. During the 12 months of follow-up, there was no recurrence of tumor growth.
