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.

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.
