Abstract
- Clear cell hidradenoma is a relatively infrequent benign tumor that shows differentiation from or toward the structure of the eccrine sweat gland. We report four cases of clear cell hidradenoma which consists mainly of typical clear cells with small numbers of polyhedral cells. Clinically these tumors represented solitary erythematous firm nodular or cystic mass. In immunohistochemical study of one case, polyhedral cells rather than clear cells reacted positively for carcinoembryonic antigen and cytokeratin. We also review the previous reports of clear cell hidradenoma in Korean dermatologic literature.
