Eccrine Spiradenoma Arising from the Breast Skin

Figure 1

Eccrine spiradenoma of breast. The tumor is located at the interface of the deep dermis and superficial breast tissue, well-circumscribed with a thick fibrotic capsule (a and b). Two-cell populations within the tumor clusters are identified with dark-grey and light-grey nuclei being evident. The two-cell populations constituting this tumor: small dark and basaloid cells with hyperchromatic nuclei and larger cells with a pale nucleus, often near the center of the cluster.
