Treatment

Under local anesthesia, a full-thickness flap around the area was raised and the area was scrapped. There was some straw-colored fluid but no solid tissue. The area was sutured and the specimen submitted for microscopic evaluation.

Excisional Biopsy

Histologic examination reveals multiple pieces of hard and soft tissue composed of bone, fibrous connective tissue with small blood vessels, extravisated erythrocytes and small fragments of peripheral nerve bundles (Figures 2 & 3). Bone comprises the bulk of the specimen and is viable. Inflammatory cells are absent.

Figure 2 Low power (x100) H & E histology illustrates fragments of bone interspersed with fibrous connective tissue containing small blood vessels, erythrocytes, and small bundles of peripheral nerve fibers.

Figure 3 Higher power (x200) H & E histology illustrates higher power of the fibrous connective tissue with small blood vessels and extravisated erythrocytes.
