Abstract

|
Solitary fibrous tumor (SFT) is rare mesenchymal tumor usually arising from pleura. SFT can be found at all anatomic site in our body but incidence of SFT is much lower in head and neck region especially at lower neck area. We found a case of SFT that presented as a lower neck mass in a 41-year old woman. Ultrasonography showed a 3×1cm sized hypoechoic mass in the intermuscular fat plane of left lower neck, and computed tomography showed a well circumscribed, low-density mass with contrast enhancement. Fine needle aspiration showed no malignant cells with abundant red blood cells, but it was not possible to completely rule out malignant tumors or nodules clinically. Surgery was performed to make a definitive diagnosis and histopathology showed tightly packed, round to fusiform cells with staghorn shaped vessels at microscopic examination. The tumor cell were positive for CD34 but negative for CD31 and S-100 protein.
