Although epithelioid blue nevus (EBN) is a rare variant of blue nevus that was first reported in patients with Carney complex, which encompasses cardiac and cutaneous myxomas, spotty skin pigmentation, endocrine overactivity, and psammomatous melanotic schwannomas,1 it has been also documented in the absence of such clinical features.2 Histological characteristics of EBN are variably pigmented, large epithelioid melanocytes with vesicular nuclei and prominent eosinophilic nucleoli and a small number of melanophages that are sometimes associated
with a few pigmented, spindle, and dendritic cells.3 EBN is a diagnostically challenging entity because of its rarity and histological overlap with other pigmented melanocytic lesions, such as cellular blue nevus, malignant blue nevus, and the so-called animal-type malignant melanoma. Because it is very uncommon and no cases have been recorded in the Korean literature,this Korean case is reported.
