The bacteria were interpreted
as likely superficial skin inhabitants. Histopathologic
examination of hematoxylin–eosin-stained
sections of formalin-fixed biopsy tissue revealed a core
of fibrous connective tissue covered by a mildly hyperplastic
keratinizing stratified squamous epithelium. A
large nodular accumulation of cholesterol clefts mixed
with numerous hemosiderin-laden macrophages,
fewer lymphocytes and plasma cells, and rare multinucleate
giant cells was present in the submucosa
(Figure 4).
