Abstract

Pleomorphic hyalinizing angiectatic tumor (PHAT) is a rare, low grade neoplasm which usually occurs in subcutaneous soft tissue. Histologically, it features ectatic blood filled vessels surrounded by hyalinized stroma and pleomorphic spindle cells. Clinically and histologically, PHAT could be misdiagnosed as such tumor as neurogenic tumor, malignant fibrous histiocytoma. About 100 cases of PHAT have been reported so far, and it is even rarer in head and neck area. We experienced a case of PHAT in 41-year-old male with several months of history of gradually enlarging neck mass which was surgically removed by wide excision.
