Blue nevi of internal organs are more similar to the so-called dermal melanocytosis than to cutaneous blue nevi.
In this report, we examine several morphologic aspects of blue nevi of internal organs, and compare them to similar conditions of the skin. From a morphologic point of view, blue nevi of internal organs are more similar to the so-called dermal melanocytoses. Nevertheless, since melanocytoses and blue-nevi seem to have the same benign prognosis, and since blue nevus is a historically consolidated term to refer to pigmented spindle cell lesions of internal organs, a most appropriate term, to refer to the latter, will not be easily accepted in literature.
