Incisional and Excisional Biopsy

The excisional biopsy revealed small fragments of bone and fibrous connective tissue.  Bone comprises the bulk of the specimen, is viable, and is both reparative and lamellar in type (Figure 3).  The bony fragments contain spaces filled with loose and vascular fibrous connective tissue (Figure 4).  Note that clusters of extravasated erythrocytes are also present .

Figure 3.  Low power (x100) histology shows small fragments of lamellar bone with viable osteocytes and small fragments of loose and vascular connective tissue within small spaces and around the bony fragments.  

Figure 4. Higher power (x200) histology shows lamellar bone and loose fibrous connective tissue.
