The epithelioid blue nevus (EBN) is considered a cutaneous marker of the Carney complex. Sporadic EBN has been reported in patients not exhibiting the Carney complex. The EBN does not exhibit unique clinical features that help to differentiate it from other lesions and is often provisionally diagnosed as an acquired melanocytic nevus, or a malignant melanoma. A 52-year-old African-American female had a 3-4 mm bluish macule of the left anterior hard palate. An excisional biopsy was performed to rule out an incipient melanoma. Formalin-fixed, hematoxylin and eosin-stained sections were examined microscopically. On the basis of histopathological features, a diagnosis of EBN was rendered. We document a case of the rare EBN affecting the oral mucosa. The patient did not exhibit any features associated with the Carney complex. Two years post-operatively, there is no evidence of a recurrent tumor.
