Pilomaticoma or Pilomatrixoma also known as cacifying epithelioma of Malherbe. It is a rare calcifying epithelioma of hair follicle matrix cell origin. It happens in the Head and Neck 50% of the time. It is sometimes associated with other genetic disorders such as Turner Syndrome, Myotonic Dystrophy, Garder’s Syndrome and Cranial Dysostosis. It seems to be slightly more prevelent in females and in young people 8-13 years of age.
Wide local excision is the treatment of choice and recurrence is rare. It does seem though that if you do not get clear margins it will persist.
