Incisional and Excisional Biopsy

The biopsy specimens showed fragments of loose and vascular granulation tissue covered by proliferative stratified squamous epithelium. The latter contained clusters of neutrophils (Fig 4). The granulation tissue supporting the epithelium was infiltrated by many neutrophils, lymphocytes, plasma cells and foamy macrophages (Fig 5)

Figure 4.  Low power (x200) histology shows small fragments of loose and vascular granulation tissue covered by non-keratinized and proliferative stratified squamous epithelium containing small clusters of neutrophils.
