Abstract
The term "nevus" was originally used with its Latin meaning of "a mark," with no conception of the etiology or pathology of the various types of lesions. As the various types of nevi were studied microscopically, other designations were utilized which seemed more appropriate; for instance, vascular nevi are now generally designated as angiomas. There are certain types, however, which have not been satisfactorily classified and for which the name "nevus" is still used. The most interesting type in this group is the pigmented nevus. More and more interest has been evinced in this lesion, and certain ideas are gaining ground. Some of the older theories of the origin of the pigmented nevus, i. e., that it was a histiocytic tumor or an endothelial tumor, have long been abandoned. The two theories which still have supporters are (1) the epidermal theory of Unna, Bloch and others and (2) the theoryThis publication has 0 references indexed in Scilit:
