Abstract

Dermal melanocytosis includes Mongolian spot, nevi of Ota and Ito, dermal melanocytic harnartoma, and blue nevus. Nevi of Ota may be respectively associated with Mongolian spot, blue nevi and unilateral or bilateral nevi of Ito. We present a case, a 24 year-old female, who had bilaterally brownish or slatebluish pigmented patches on the face, sclera, neck, anterior chest, deltoid, supraclavicular, scapular, back and sacrococcygeal area. And also she had a bluish, bean-sized nodule on her left mid-back. It is likely that this case may be considered as an extremely extensive case of pig:m.entary anomaly, associating aberrant and persistent mongolian spots, extensive nevus of Ito, bilateral nevus of Ota and blue nevus. To our knowledges it seems that such case has not previously been reported in Korean literature.
