Sample item

A 50-year-old man has a slowly growing multilocular radiolucency in the anterior mandible crossing the midline. Histology shows cuboidal cells with mucous cells and ciliated cells lining the cavity. The lesion tends to recur after enucleation. What is it?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Glandular odontogenic cyst

The glandular odontogenic cyst is a rare lesion with a lining containing mucous and ciliated cells. It is often multilocular, found in the anterior mandible, and recurs frequently, so wider excision may be needed. It can mimic a low-grade mucoepidermoid carcinoma.

Option by option

  • A. Glandular odontogenic cyst (correct)

    Correct. Mucous and ciliated cells in an anterior mandibular multilocular cyst fit this cyst.

  • B. Dentigerous cyst

    A dentigerous cyst surrounds the crown of an unerupted tooth.

  • C. Lateral periodontal cyst

    A lateral periodontal cyst is a small unilocular lesion beside a vital root.

  • D. Radicular cyst

    A radicular cyst is a periapical inflammatory cyst and does not recur like this.
