Desmoplastic fibroma of bone with extensive cartilaginous metaplasia.

Desmoplastic fibroma of bone is a rare tumor demonstrating the same histologic and biologic features of its soft tissue counterpart, aggressive fibromatosis. We report the second case of desmoplastic fibroma of bone with extensive chondroid metaplasia. The tumor arose in the left ischium of a 51-year-old male, with extension into adjacent musculature as a pseudoencapsulated mass.

A brief history of head and neck pathology.

Surgical pathology had its beginnings in the late 1800s. A biopsy that gained much attention was from the larynx of Crown Prince Frederick in 1887. The tissue was seen by Rudolph Virchow and the clinical management of the Prince eventuated in a highly publicized furor.
