title: [Eccrine syringofibroadenoma. Report of clinical aspects and histology of two cases with review of the literature].
abstract: Eccrine syringofibroadenoma is a rare benign neoplasm with differentiation towards eccrine ducts. Its recognition depends on the histopathological examination; it is to be differentiated mainly from fibroepithelial basal cell carcinoma. Two new cases which occurred in a 70-year-old woman and a 39-year-old woman are presented. Clinically the two neoplasms were each a solitary hyperkeratotic, partially oozing nodule. On microscopic examination they both showed proliferation of small neoplastic cells in a reticular pattern; immature or mature eccrine ductal structures were seen within them. The neoplastic cells in the two cases differed in their content of PAS-positive glycogen.
