Histopathologic examination of the biopsy showed a dermis full of pigment-laden macrophages and multinucleated giant cells with haphazard arrangement of nuclei. Subjacent to the dermis were hypertrophic PCs. The 2 onionlike corpuscles seen in Figure 3 have approximately 33 and 20 concentric lamellae. The dermal changes represent a foreign body reaction to paint. The enlarged PCs are the likely source of progressive pain and represent a rare condition called PC hyperplasia, sometimes called Pacinian neuroma.
