The answer and the reasoning

A. Ameloblastoma

Ameloblastoma is a locally aggressive benign odontogenic epithelial tumour of the mandible, commonest at the angle and ramus, with a multilocular soap-bubble appearance. It recurs if enucleated, and treatment is wide resection with margins of 1 to 1.5 cm. It does not metastasise typically.

Option by option

  • A. Ameloblastoma (correct)

    Correct. A multilocular lesion at the angle suggests ameloblastoma.

  • B. Osteosarcoma

    Osteosarcoma gives a sunburst periosteal reaction.

  • C. Mandibular torus

    A torus is a bony exostosis.

  • D. Dentigerous cyst

    A dentigerous cyst is unilocular and surrounds an unerupted crown.
