The epidermis showed hyperplasia in many of the biopsy specimens. The predominant finding over time was an inflammatory dermal infiltrate composed of polymorphonuclear leukocytes, lymphocytes, plasma cells, and histiocytes, with varying numbers of foreign body giant cells. Many of the biopsy specimens showed focal abcess formation, and gram-positive organisms were noted in at least 1 biopsy specimen. Dermal fibrosis was present in many of the specimens that were obtained later.
