title: A case of cutaneous ganglioneuroma developing within a lesion of seborrheic keratosis.
abstract: A 67-year-old man noticed on the abdominal skin a coin-sized verrucous plaque, in which a small granulation-like lesion developed several weeks before the first consultation at our clinic. The histology of the biopsied granulation-like lesion showed a well demarcated, but not associated with the collagenous capsule, mass of proliferating eosinophilic cells, consisting of intervening spindle-shaped Schwann cells and mature ganglion cells scattered in the tumor nest. We diagnosed this tumor nest as a ganglioneuroma, which rarely develops in the skin tissue. The simply resected surrounding verrucous lesion was histologically seborrheic keratosis.
