PIGMENTED HAIRY NEVUS OF THE NOSE: WITH PIGMENTED HAIRY AND WARTY NEVUS OF THE CHEEK AND LIP

Archives of Otolaryngology - Head and Neck Surgery, 1925
The case that I report does not offer anything very new with regard to the operative procedure employed to remove the nevus in question. I shall draw a comparison between the different surgical methods at our disposal, and at the same time say a few words on the use of physical agents for this kind of condition. In choosing autoplasty, I was especially

IDENTIFICATION OF MALIGNANT POTENTIALITIES OF MELANOCYTIC (PIGMENTED) NEVUS

Journal of the American Medical Association, 1956
• An attempt is made to state the clinical features by which the physician can decide whether a common pigmented mole, appropriately designated as a melanocytic nevus, should be removed. At the junction or interface between epidermis and dermis lie the melanocytes whose multiplication and extrusion into the dermis is called junctional activity ...

DEFINING THE MALIGNANT POTENTIAL OF THE GIANT PIGMENTED NEVUS

Plastic and Reconstructive Surgery, 1976
An unusual giant pigmented nevus, containing lymphocytic infiltrates and apparent muscle invasion, but without the presence of melanoma, is described in detail--including its related immunological parameters. The controversy concerning the malignant potential of giant pigmented nevi, and the paradoxes that are encountered clinically, are discussed.

Eosinophilic Globules in Pigmented Spindle Cell Nevus

The American Journal of Dermatopathology, 1990
Reed's pigmented spindle cell nevus is often misdiagnosed as malignant melanoma despite reliable clinical and histopathologic diagnostic features. In the present report, 10 cases of pigmented spindle cell nevus were studied with step sections to identify Kamino's eosinophilic globules.
