Abstract |
Pilomatrixoma is an unusual benign cutaneous tumor, originating from precursor cells that normally differentiate into hair matrix cells. The majority of pilomatrixoma is seen in the first two decades of life, and they are extremely rare in older patients. Thus, pilomatrixoma is often not considered in the clinical differential diagnosis of solitary, firm nodules in older adults. Most present as firm, solid nodules in the head and neck region. We present two cases of a non-calcifying pilomatrixoma in older patients. One lesion arose from the upper neck in 54 year-old male and the other from the cavum concha of left ear in 35 year-old male. |
