Talon cusp variations: 2 case reports.

Talon cusps in anterior teeth are relatively rare developmental anomalies. They are characterized by the presence of an accessory cusp-like structure projecting from the cingulum area or cementoenamel junction. Facial talons occur very rarely; <10 cases have been described in the literature. This article attempts to describe the variants of this anomaly with 2 case reports involving facial and bilateral palatal manifestation.

A rare case of unicystic ameloblastoma with luminal, intraluminal, and intramural proliferation.

Unicystic ameloblastoma (UCA) is a cystic lesion that shows clinical, radiographic, or gross features of an odontogenic cyst, but reveals a typical ameloblastomatous epithelium lining in the cyst cavity, with or without luminal and/or mural tumor growth. This article reports the case of a 22-year-old man with dull intermittent pain and swelling in the mandible. Histopathological examination revealed a UCA of a luminal, intraluminal, and intramural histological subgroup, which has a high risk for recurrence.

Desmoplastic ameloblastoma: a report of two clinical cases

Desmoplastic ameloblastoma is a relatively rare histological variant of ameloblastoma with specific clinical, radiological, and histological features. Although radiographic examination of ameloblastomas usually reveals unilocular or multilocular radiolucency, desmoplastic ameloblastoma may appearas a mixed radiopaque-radiolucent lesion resembling benign fibro-osseous lesions. Histologically, desmoplastic ameloblastoma is characterized by small nests and strands of “compressed”odontogenic epithelium supported by pronounced collagenized stroma. This report describes two cases of desmoplastic ameloblastoma in the anterior maxilla of a female patient and the anterior mandible of a male patient, mimicking clinically as an odontogenic cyst.
