Abstract: Nevus of Ota is a hamartoma of dermal melanocytes. The cause for it unknown, but certain theories have been postulated wherein it has been suggested that it results from failure of migration of melanocytes from the neural crest to dermoepidermal junction. It is also hypothesized that these aberrant dermal melanocytes may be influenced hormonally. Clinically, it depicts a characteristic pattern of the bluish black pigmentation along the cutaneous distribution of the trigeminal nerve. Literature review shows a very few substantial cases reported and incidence of such cases are very meagre in our Indian subcontinent. Prevalence of such cases is directed towards female population and its occurrence in oral cavity is quite rare. This is a case series of unilateral Nevus of Ota of a 28 year old male and 35 year old female patient with oral manifestations.
