“…Any area of the oral cavity can be affected, although most lesions are observed on the palatal mucosa. The oral pigmentation in nevus of Ota is described as irregularly shaped, macular, flat and bluish [9, 19, 20]. Hidano et al [19] found an involvement of the oral mucosa in 11 of 61 cases (18%) of nevus of Ota.…”

“…The sclera, conjunctiva, cornea, iris, retina, optic nerve, extraocular muscles, retrobulbar fat, the pharynx, the nasal mucosa and the tympanic membrane may be involved. Involvement of the mucosa of the oral cavity is not an uncommon feature in Japanese subjects but can be found only very rarely in non-Orientals [9, 18]. Any area of the oral cavity can be affected, although most lesions are observed on the palatal mucosa.…”

“…In all cases, the oral blue-black pigmentation was located near the midline of the palate in a sagittal extension. Page et al [9] reviewed the non-Orientals with oral involvement of nevus of Ota. They found only 7 cases reported in the literature, 5 in whites [9,10,11,12,13], 2 in blacks [20].…”

Background: The blue nevus of the oral cavity is a rare lesion with important differential diagnoses. The plaque-type blue nevus is an uncommon variant of the blue nevus. Because of its particular clinical appearance, it can easily be confused with satellite metastases from malignant melanoma. The diagnosis usually requires a biopsy. Objectives: To describe the clinical and histological features of a plaque-type blue nevus of the buccal mucosa in a 20-year-old white woman, to review all intraoral blue nevi and all plaque-type blue nevi reported in the literature so far and to compare the criteria of blue nevi and nevus of Ota. Results: An intraoral blue nevus was described for the first time in 1959. Since then around 70 further cases have been documented. Our case is the first report of a plaque-type blue nevus of the oral cavity. Conclusions: The exceptional widespread intraoral blue nevus described herein can clinically be confused with an intraoral malignant melanoma, and it has a very similar clinical appearance as the intraoral part of nevus of Ota. Apart from the clinical resemblance, there is also some degree of histological overlap of the dermal melanocytoses. Transitional states between blue nevus and nevus of Ota may occur clinically and histologically.

“…7 Involvement of the nasal, buccal, palatal, and pharyngeal mucosa is also not unusual. 2,8 Nevus of Ota appears to have a female predilection. 1 It is far more widespread in Asian populations, with an estimated incidence of 0.1% in this group.…”
