Figure 4: Intraoperative view: Incisional biopsy taken at the site of the lesion.(a) Low power view of the histological section showed marked cellular infi ltrate in the connective tissue (H&E stain, x40)(b) Photomicrograph shows aggregates of histiocytes along with lymphocytes (H&E stain, x100). (c) High power view shows aggregates of histiocytes with indistinct cell borders and pale eosinophilic cytoplasm (H&E stain, ×400). (d) The histiocytic cells showing positivity for S-100 protein (IHC stain, ×100). (e) The aggregates of histiocytes were positive for CD 1a protein (IHC stain, ×400)
