Amyloid deposition was encountered in 10 of 16 samples of pilomatricoma, indicating that the deposition of amyloid is nearly as common as calcification in pilomatricoma. In addition, a simultaneous occurrence of calcification and amyloid deposit in pilomatricoma was recognized in 9 of 16 samples. The calcification and the deposition of amyloid developed topographically in the same area within the shadow cell masses. Such an area was revealed as moderately basophilic, amorphous, or hyalinized by H&E staining. Electron microscopy revealed spotty calcium deposits in amyloid. No light chains of human immunoglobulin were detected in the amyloid-deposited area. Amyloid in this tumour may facilitate calcification or serve as a matrix for subsequent calcification.Downloads
