Treatment

Under local anesthesia, an incisional biopsy was performed and the specimen was submitted for microscopic examination.

Excisional Biopsy

Histologic examination reveals multiple pieces of soft tissue composed of a mass of granulation tissue with many giant cells which are haphazardly arranged (Figures 3 & 4). The granulation tissue is loose, cellular and has many small blood vessels. It contains clusters of hemosiderin pigment. The granulation tissue also contains many giant cells of variable shapes and sizes haphazardly arranged some closely associated with small blood vessels.

Figure 3 Low power (x100) H & E histology shows a mass of granulation tissue with many giant cells which are haphazardly arranged. The granulation tissue is loose and cellular, with many small blood vessels.

Figure 4 Higher power (x200) H & E histology shows many giant cells suspended on vascular granulation tissue.
