Which histopathological feature is associated with chondroblastoma?

• A. Chick-pea morphology
• B. "Chicken-wire calcification"
• C. Cystic degeneration
• D. Giant cell formation

Answer: (B)

Chondroblastoma is a benign bone tumor that is primarily found in the epiphyses of long bones, particularly in young adults and adolescents. The histopathological feature known as "chicken-wire calcification" is a distinctive characteristic observed in chondroblastomas. This involves the presence of small calcifications that create a lattice-like appearance within the tumor, resembling a chicken wire. This feature arises from the presence of calcified cartilage matrix and is a key diagnostic indicator for pathologists when evaluating biopsy specimens from suspected chondroblastomas. In addition to this, chondroblastomas exhibit various other histopathological features such as round to oval cells resembling chondroblasts, a high cellularity, and sometimes a multinucleated giant cell formation, but the specific "chicken-wire calcification" stands out as a signature feature that aids in the definitive diagnosis of this tumor. Understanding this characteristic is crucial for correctly identifying chondroblastoma and differentiating it from other bone lesions that may have overlapping features.
