Mucoepidermoid Carcinoma of the Breast
Mucoepidermoid carcinoma (MEC) of the breast is a tumor composed of mucous-secreting intermediate and epidermoid cells. It can present a great variety of architectural patterns, ranging from cystic to solid. Its features are similar to MEC arising in the major and minor salivary glands (Foschini et al. 2017; Foschini and Krausz 2010).
MEC affects mainly adult patients, aged from 29 to 80 years.
At present breast MEC has been described in female patients only.
MEC can arise in all breast quadrants. When it affects the retro-areolar region, it can present with nipple discharge.
Radical surgical resection is the treatment of choice. Axillary lymph node dissection and chemotherapy have been added in high-grade MEC.
Outcome mainly depends on MEC grading. MEC,...
