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.

Three-dimensional imaging of progressive facial hemiatrophy (Parry-Romberg syndrome) with unusual conjunctival findings.

Progressive hemifacial atrophy, also known as Parry-Romberg syndrome, is an uncommon degenerative condition which is poorly defined. It is characterized by a slow and progressive atrophy affecting one side of the face. The onset usually occurs during the first two decades of life. Characteristically, the atrophy progresses slowly for several years, and then it becomes stable. Ophthalmic involvement is common, with progressive enophthalmos which is a frequent finding. Cutaneous pigmentation is common in such conditions, however its extension to the conjunctiva is rarely reported. We report a case of Parry Romberg syndrome with characteristic clinical and radiographic presentation accompanied with rare ocular findings. The clinical features, radiological findings, and differential diagnoses to be considered, and the available treatment options are discussed in this report.

Asymptomatic presentation of aggressive ossifying fibroma:a case report.

Ossifying fibromas form a part of the spectrum of fibro-osseous lesions of the jaws. They are rare, benign, nonaggressive tumors that are commonly seen in head and neck region. This paper presents the case of a 40-year-old female patient presented with minimal clinical symptoms, diagnosed to be suffering from aggressive form of ossifying fibroma of maxilla involving the maxillary sinus and ethmoid sinus. This paper emphasizes the importance of computed tomography in diagnosing such unapparent aggressive tumors.

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.
