Abstract:
:Surgically resected specimens of skin appendage tumors, spiradenoma, poroma of eccrine glands, syringoadenoma, syringoadenoma papilliferum and mixec tumor of skin were evaluated for tenascin, as well as the basement membrane-associated protein laminin, and the extracellular matrix protein fibronectin, using immunohistochemical methods. In normal sweat glands, tenascin was localized as a delicate, thin band in the immediate vicinity of the basement membrane and laminin was limited to the basement membrane. Tenascin in syringoadenoma was also expressed linearly adjacent to the basement membrane. Mixed tumors of skin showed a characteristic distribution of tenascin in the modified myoepithelial cell area adjacent to the tumor epithelia with a heterogeneous pattern, and particularly strong expression in the hyalinous and chondroid areas. In addition, the localization of laminin in the basement membranes of tumors, intracellular immunoreactivity was observed in syringoadenoma, syringocystadenoma papilliferum, and mixed tumor of skin. Fibronectin reactivity was visualized as a diffuse staining in the tumor stroma of eccrine poroma but its expression was restricted in eccrine spiradenoma. The present study suggests a heterogeneity in the distribution of basement membrane and extracellular matrix proteins in skin appendage tumors and elucidation of their functional roles would assist in understanding the changes in the supporting tumor stroma following neoplastic changes.
