Multinodular pilomatrixoma.
A hard deep nodule, 6 x 3 mm in size, was excised from the cheek of a 12-year-old girl. The histological sections showed a multinodular cyst-like proliferation, each nodule showing the typical structure and cytology of pilomatrixoma. A comparison is made between this case and the budding phenomenon that has been described in isthmus-catagen (tricholemmal) cyst.
