Eosinophilic globules in pigmented spindle cell nevus

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. Eighty percent of the cases disclosed numerous eosinophilic globules, supporting the hypothesis that this nevus is a variant of Spitz's nevus. Kamino's eosinophilic globules could be considered another important sign for the differential diagnosis between pigmented spindle cell nevus and malignant melanoma.
