A granulomatous dermal infiltrate consisting predominantly of histiocytes and multinucleated giant cells of Langhans and foreign body types, as well as lymphocytes and rare eosinophils, was evident on hematoxylin-eosin–stained sections. The granulomas were located in the upper half of the dermis and were focally periadnexal in distribution (Figure 2 and Figure 3). Special stains were negative for mycobacteria and fungal organisms. Polarizable material was not identified within the granulomas.
