Which neoplasm shows histology with Léstage ring calcification?

• A. Odontogenic Keratocyst
• B. Pindborg tumor
• C. Ameloblastoma
• D. Osteosarcoma

Answer: (B)

The presence of Léstage ring calcification is specifically associated with the Pindborg tumor, also known as an calcifying epithelial odontogenic tumor (CEOT). This type of neoplasm is characterized histologically by the prominent feature of concentric layers of calcified material, which appear as Léstage rings. These rings are a result of calcification within the tumor and help to distinguish it from other odontogenic tumors. In the case of the Pindborg tumor, the tumor typically arises in the jaw and has a unique histological appearance that sets it apart from other tumors, such as the odontogenic keratocyst, ameloblastoma, and osteosarcoma. While ameloblastoma may show various patterns of calcification, it does not feature Léstage rings. Similarly, the osteosarcoma typically presents with different histological characteristics, primarily involving spindle-shaped cells and varying degrees of bone production. The odontogenic keratocyst is more known for its keratinized epithelium rather than calcification patterns. Recognizing Léstage ring calcification is crucial in identifying Pindborg tumors within the spectrum of odontogenic neoplasms, making it a distinct histological marker that is characteristic of this specific tumor
