Immunohistochemical Study of Cytokeratin Polypeptides in Eccrine Gland Tumors

Abstract
|
|
|
Background :
@EN Different distributions of cytokeratins (CKs) have been found in various layers of the epidermis and in the structure of cutaneous appendages. Benign tumors of the epidermis or cutaneous appendages usually retain the characterisitic
distribution of
CKs of their origin.
@ES Objective and Method :
@EN To elucidate the nature and differentiation of various eccrine gland tumors, we performed immunohistochemical staining using a panel of monoclonal antibodies against CKs in a normal eccrine gland, syringoma, eccrine hidrocystoma, eccrine
poroma
and
clear cell hidradenoma. The tissue distribution of various keratins in the normal eccrine gland was compared with that in various eccrine gland tumors.
@ES Results :
@EN With regard to CKs expression, the results indicated that syringoma represents a tumor differentiating toward both the uppermost part of the dermal duct and the lower intraepidermal duct, and eccrine hidrocystoma represents a tumor
differentiating
toward the luminal cell f the dermal duct of the eccrine gland. Eccrine poroma cells seemed to be most closed related to the uppermost dermal duct of eccrine gland. We also found that analyse distribution of CKs was insufficient to elucidate the
histogenesis of clear cell hidradenoma.
@ES Conclusion :
@EN Analysing CKs is helpful in the analysis of epidermal neoplasms with differentiation toward the eccrine gland. (Kor J Dermatol ;34(1) : 78~84)
