Ectopic Eruption of a Transmigrated Mandibular Canine: A Rare Case Report.

Migration of teeth, both physiological as well as pathological, is a well-documented phenomenon. Transmigration, on the other hand, is a rare phenomenon where a tooth crosses the midline and migrates to the opposite side without any pathological influence. An impacted tooth especially canines migrate to a location some distance away but do not usually cross the midline. Even so, the tooth remains impacted. Here is a unique case of transmigration of a left mandibular canine, which has erupted labial to its counterpart on the right mandibular arch. Transmigration of the mandibular canine is a rare phenomenon. Even rare is an eruption of this transmigrated canine into the opposite arch where it can be mistaken as a supernumerary tooth.

Pigmented Basal Cell Carcinoma: A Case Report.

Basal cell carcinoma (BCC) which is also known as rodent ulcer is the most common type of skin cancer. Prolonged exposure to high-intensity ultraviolet radiation is regarded as the most common risk factor of BCC. This ionizing radiation can induce DNA damage such as point mutations, and single stranded DNA breaks. Other possible pathogenic mechanism includes the involvement of the tumor suppresser gene, and the members of sonic hedgehog signal transduction pathway. Pigmented BCC (PBCC) is a rare variant of BCC, of which only very few cases have been reported in literature. This is a case report of such a case of PBCC.

Efficacy of Diode Lasers in the Treatment of Oral Leukoplakia: A Case Report.

Leukoplakia of the buccal mucosa is considered a premalignant lesion according to the WHO classifi cation with a malignant transformation rate of 0-20%, especially among men above 40 years of age with a smoking history. Along with the active screening procedures, there is also growing brilliance in surgical interventions aimed at the eradication of such fatal diseases. Laser ablation using diode lasers is one such well-accepted prophylactic treatment modality among clinicians and patients along with low recurrence rates. We have aimed to support this article with the case report of the patient with leukoplakia, who was being treated with a diode laser that unveiled the brilliance of this technique with enhanced healing.

Extra Gingival Pyogenic Granuloma: Unusual Location for the Usual Lesion.

Pyogenic granuloma (PG) is a benign non-neoplastic mucocutaneous lesion formed in reaction to mild irritation or hormonal changes. Although this fairly common lesion has a striking predilection for the gingiva, it can also be found extra gingivally. The clinical diagnosis of such an uncommon extra gingival PG can be quite challenging as the lesions appear as smooth or lobulated red nodules with easy bleeding, occasionally ulcerated mimicking malignancies. The purpose of this article is to report an unusual case of extra gingival PG occurring on the upper lip. The diagnosis of oral lesions is complex due to distinct appearance of the same lesion and leads the clinician to consider lesions with different diagnostic methods.

Oral Manifestations of Neurofibromatosis: A Rare Case Report.

Neurofibroma (NF) is a rare benign non-odontogenic tumor of the oral cavity. NF may present either as solitary lesions or as part of the generalized syndrome of NF or von Recklinghausen’s disease of the skin. The heterogeneous nature of NF was established by Riccardi et al. and he recognized at least seven types of NF. Among these proposed classifications of the disease, two distinct forms are generally accepted namely, a peripheral form known as NF Type I (NF-I), and a central form known as NF-II. NF-I represents the classic form of this disease, described by Recklinghawsen in 1882. Clinically, oral NF usually appears as slow growing, painless, pedunculated or sessile nodules. For illustration, a case of a NF with oral findings is been presented.

Odontoameloblastoma: A Diagnostic Dilemma for Maxillofacial Radiologist / Odontoameloblastoma: Un Dilema Diagnóstico para el Radiólogo Maxilofacial

Odontoameloblastoma is a rare neoplasm of odontogenic origin in which there is proliferation of tissue of the odontogenic apparatus in an unrestrained pattern including complete morphodifferentiation, apposition and even calcification. Till date, around 20 cases have fulfilled the histologic criteria of the current World Health Organization histologic classification of odontogenic tumors. Review of literature from 1944 to 2011 reveals only four reported cases in the anterior mandible. Here, we report a case of odontoameloblastoma in the anterior mandible in which plexiform ameloblastoma was associated with compound odontoma forming an unusual combination.

El odontoameloblastoma es una neoplasia rara, de origen odontogénico en el que existe proliferación tisular del aparato odontogénico en un patrón sin restricciones, incluyendo morfodiferenciación completa, aposición e incluso calcificación. Hasta la fecha, alrededor de 20 casos han cumplido todos los criterios histológicos de la actual clasificación de tumores odontogénicos de la OMS. La revisión de la literatura desde 1944 hasta el año 2011 revela sólo cuatro casos reportados en el sector mandibular anterior. Se presenta un caso de odontoameloblastoma en la region anterior mandibular donde un ameloblastoma plexiforme se asoció con un odontoma complejo formando una combinación inusual.

Mural unicystic ameloblastoma crossing the midline: a rare case report / Ameloblastoma uniquístico mural traspasando la línea mediana: reporte de un caso infrecuente

Ameloblastoma is a benign odontogenic neoplasm which frequently affects the mandible. The term ameloblastoma includes several clinico-radiological and histological types. Apart from the most commonly encountered clinico- pathologic models there are few variants, whose biological profile is unknown or not elicited. The reason for lack of understanding is the scarcity of case report published in the literature. Among the types, unicystic ameloblastoma is the least encountered either it presents as unilocular or multilocular radiolucency, but peculiar radiographic presentation of multilocular radiolucency in posterior mandible with unilocular radiographic appearance crossing the midline is extremely rare, which has not been reported yet. Here we report a distinctive case of mural unicystic ameloblastoma of mandible in a 17-year- old- girl with the radiographic presentation as mentioned above.

El ameloblastoma es un tumor odontogénico benigno que frecuentemente afecta a la mandíbula. El término ameloblastoma incluye varias características clínico-radiológicas y tipos histológicos. Aparte de los modelos clínicopatológicos que se encuentran con frecuencia existen algunas variantes, cuyo perfil biológico es desconocido o aún no elucidado. La razón de la falta de comprensión es la escasez de informes de casos publicados en la literatura. Entre los tipos, el ameloblastoma uniquístico es el menos frecuente y puede presentarse como una radiolucidez unilocular o multilocular, pero la peculiar presentación radiográfica de radiolucidez multilocular en el posterior de la mandíbula con aspecto radiográfico unilocular que cruza la línea mediana es extremadamente rara, y aún no se ha reportado. Se presenta un caso de ameloblastoma uniquístico mural de la mandíbula en una paciente de 17 años con la presentación radiográfica anteriormente descrita.
