Abstract
- Pilomatricoma is a rare benign neoplasm arising from the outer sheath of hair follicles. A firm, freely movable, and well-circumscribed subcutaneous nodule is a characteristic clinical feature of pilomatricoma. Diagnosis is usually based on clinical features, and surgical excision is performed without the use of imaging. Radiological evaluation has been used primarily as a means for differentiating pilomatricoma from other tumors or inflammatory conditions and also for examining unusually large or aggressive tumors. As a result it is important to be familiar with radiological characteristics of pilomatricoma. In this report, three cases of pilomatricoma from a pool of 28 pathologically confirmed cases are examined. Characteristic radiological findings of pilomatricoma are well-defined, oval shaped subcutaneous nodules adherent to the overlying skin with various amounts of calcification on plain radiography, CT scan, and ultrasound.
