Pilomatricoma in the head and neck: CT findings in three patients.

摘要

We report three cases of pilomatricoma, one in the infrahyoid neck and the others in the preauricular area. In all cases, CT showed well marginated soft tissue masses that were located mainly in the subcutaneous fat, partly attaching to the overlying skin. There was no evidence of infiltration to deeper structures. Substantial amounts of calcification were found in one tumor. Pilomatricoma should be included in diagnostic consideration when CT shows a well marginated subcutaneous soft tissue mass adherent to the skin with or without visible calcification in the head and neck region.
