“…Oral blue nevus has a prevalence of 0.1% in the general population, appears mainly from the third to the fifth decades, and women tend to be more affected than men [ 2 , 4 , 7 , 14 ]. It develops more frequently in the hard palate (69%), followed by the labial mucosa and vermillion border [ 1 – 3 , 5 – 7 , 14 ].…”

“…It develops more frequently in the hard palate (69%), followed by the labial mucosa and vermillion border [ 1 – 3 , 5 – 7 , 14 ]. Most lesions are asymptomatic, and therefore, its oral presentation is mostly discovered during routine dental examinations [ 2 , 15 ]. Clinically, the common blue nevus usually presents as a solitary, smooth-surfaced, well-defined, flat, or elevated papule with a diameter of less than 10 mm, though wider lesions have been described [ 1 , 2 , 5 , 7 , 9 , 11 , 13 ].…”

Its color varies from brown to blue, depending on the pigment quantity and depth or location [ 2 – 5 , 13 ]. Histologically, the diagnostic cell of the blue nevus is a pigmented, spindle-shaped dendritic melanocyte with a slender, branching network of dendritic processes without atypia or mitotic figures [ 1 – 3 , 7 , 10 – 13 ].…”

“…Histologically, the diagnostic cell of the blue nevus is a pigmented, spindle-shaped dendritic melanocyte with a slender, branching network of dendritic processes without atypia or mitotic figures [ 1 – 3 , 7 , 10 – 13 ]. The nuclei are small, elongated, and hyperchromatic [ 2 , 11 , 13 ]. Blue nevus' cells are frequently positive to S100, MelanA (MART-1), and HMB-45 [ 2 , 4 , 11 , 13 ].…”

Oral common blue nevus is an asymptomatic, benign, rare, pigmented lesion and sometimes clinically indistinguishable from other pigmented lesions such as the cellular blue nevus or early-stage malignant melanoma. Since it shows clinical similarities with a malignant lesion and with cellular blue nevus that can itself suffer malignant transformation, the decisive diagnosis is crucial for adequate treatment, follow-up, and prognosis. Diagnosis confirmation is given by histological analysis, the reason why most oral pigmented lesions are excised. The following case presents an asymptomatic oral pigmented lesion of the hard palate discovered during observation in an emergency setting due to an abscess of dental origin. The lesion was fully excised, and histological examination reported a “common blue nevus.” In this case, we intend to present a rare lesion of the oral cavity and the importance of performing a routine oral examination when given a chance as a preventive approach.

Blue Nevus: A Case Report

Oral melanocytic nevi are rare and benign tumors arising from melanocytes located in the oral mucosa. These lesions are clinically asymptomatic and often discovered during a dental consultation . All melanocytic proliferations are not benign and an histological examination have to be performed to rule out malignancy and adjust the treatment and the follow-up. Herein, we presented the case of a 23-year-old-Asian woman with an asymptomatic pigmented lesion on the hard palate discovered during a dental consultation. The lesion was excised and sent to the anatomopathological laboratory and turned out to be a blue nevus, a particular subtype of nevus.
