Acquired Generalized Blue Nevi

Blue nevus is a benign melanocytic neoplasm and represents itself usually as a solitary blue or blue-black papule. It rarely occurs as multiple lesions grouped in a circumscribed area. How-ever, non-grouped disseminated blue nevi are exceedingly rare.

We report a patient with acquired multiple blue nevi that was distributed over the entire body discretely and showed an increase in the number of the nevi without any causal factors.
