Intra oral junctional nevi: a rare case presentation with review

Aim: The aim of this case report is to enlighten about an intra oral lesion that had a clinically challenging presentation, which highlights the importance of the differential diagnosis of oral pigmented lesions. Background: Melanocytic nevus is the accumulation of melanocytes predominantly in the dermo-epidermal junction. They are often quite darkly pigmented, mostly macular or very thinly papular with minimal elevation above the skin. They are an acquired lesion and may change characteristic to that of a compound nevus. Though they are benign lesions, they have the potential to transform into malignant lesion. Case description: The following is a case report of a 29 year old female patient who reported with an irregular pigmented growth, which had a slight exaggerated appearance in an unusual site, and on excision proved to be a junctional nevus. Conclusion: Proper visual examination is always necessary as it may reveal pathological cases which are left unnoticed by patients. Clinical significance: As a dental professional, it is important for us to recognise the common as well as rare lesions of the oral cavity to list down a differential diagnosis for a proper investigatory and treatment modality.
