Fine Needle Aspiration Cytology of Eccrine Acrospiroma of the Breast: Report of a Case Misdiagnosed as Ductal Carcinoma.: Young Ok Kim, Chang Wan Jeon, Hee Kyung Chang; Korean J Cytopathol. 2005;16(1):31-35.

Abstract PDF: Eccrine acrospiroma is a rare adnexal tumor of the skin. When the clinical presentation is that of a breast lump, diagnosis can be difficult. Also, most of the cytopathologists are not familiar with the cytologic features of this tumor and this is responsible for diagnostic pitfalls. We experienced a case of eccrine acrospiroma of the right breast in a 41-year-old female, misdiagnosed by fine needle aspiration cytology(FNAC). FNAC was characterized by tight clusters or sheets of small round cells, polygonal cells, and spindle cells and tubule like structures within clusters. Myoepithelial cells were not noted in the clusters. The diagnosis of eccrine acrospiroma was confirmed by histology.

Malignant Eccrine Acrospiroma: A case report.: Gil Ro Han, In Sun Kim, Kye Yong Song, Ki Duck Kim, Beom Woo Yeom, Jong Sang Choi; Korean J Pathol. 1993;27(5):538-541.

Abstract PDF: A case of malignant eccrine acrospiroma of the anterior chest wall is reported. This mass had been present for 20 years and during rescent 5 years it showed frequent ulceration and bleeding suggesting malignant transformation. Microscopically, several foci malignant transformation from preexisting benign eccrine acrospiroma are seen and in immunohistochemical staining, the tumor cells both benign and malignant portion, show positive reaction to cytokeratin.
