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.

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.

Proliferative Veruccous Leukoplakia: An Extensive Red and White Lesion.

Proliferative verrucous leukoplakia (PVL) is a rare form of leukoplakia, which was first described by Hansen et al. in the year 1985. PVL is a disease with aggressive behavior due to its high rate of recurrence and a high rate of malignant transformation, usually more than 70%. This is a long-term progressive condition, which is observed more frequently in females over the age of 60 years. In the course of time, PVL tends to become multifocal with progressive deterioration of the lesions, making it more and more difficult to control. Unlike other cases of leukoplakia, tobacco use does not seem to have a significant influence on the appearance and progression of PVL. As this condition is seen in non-smokers, the etiology of PVL remains unclear making the management and diagnosis difficult. The aim of this article is to present a case which is diagnosed based on the diagnostic criteria proposed by Cerero-Lapiadra et al.

Multiple Supernumerary Teeth in a Non Syndromic Patient: Case Report.

Supernumerary teeth, also known as hyperdontia, is a term used to describe extra teeth that develop in addition to the 20 primary and 32 permanent teeth that we are predisposed to have. Hyperdontia is seen more commonly in the permanent dentition than primary teeth. Th e incidence in the permanent dentition is reported to vary between 0.1% and 3.8%, and its frequency in the primary dentition is found to be 0.3-0.8%. A 32-year-old male patient reported to the department of oral medicine and radiology with the chief complaint of stains and deposits, his clinical examination revealed 9 supernumerary teeth and panoramic radiographic revealed 3 more extra making a total of 12 supernumerary teeth.
