Unusual case of Pilomatrixomas with myotonic dystrophy

A 40-year-old female Caucasian patient presented at the Oral and Maxillo-facial clinic Leeds Dental Institute with a 12-month history of multiple firm nodules in the left scalp, right temple and right posterior neck, eight in number. The patient also suffers from myotonic dystrophy and hypothyroidism. Excisional biopsy reveal circumscribed nodules composed of varying proportions of basaloid cells, eosinophilic ghost cells in the central part, calcifications and foreign body-type giant cells. The appearances are entirely in keeping with Pilomatrixoma.
