A case of eccrine epithelioma / 대한피부과학회지

Eccrine epithelioma is an exceedingly rare cutaneous tumor ancit is believed to represent the maligant counterpart of the eccrine dermal syringoma. It occirs as an infiltrating basaloid growth, usually on the scalp or head, that frequently recur, apparrntly because of inadequate excision. We report a case of this tumor in a 60-year-old female, who showed a well demarcated, tender nodule on her left parietal scalp which had been present for three years. Histopat.hologically, the tumor was composed of strands of darkly staining epithelial cell embedded in a dense fihrcus stroma with ductal differentiation and cyst formation.
