Abstract

Encapsulated apocrine papilloma of the breast without myoepithelial cell markers is a rare occurrence. For its diagnosis, histopathological examination shows encapsulated apocrine papilloma lacking myoepithelial cell markers. To the best of our knowledge, this is the first documented case of an encapsulated apocrine papilloma entirely devoid of myoepithelial cell markers.

Keywords: apocrine tumor; mastectomy; myoepithelial; papilloma of the breast.
