Cutaneous Mucoepidermoid Carcinoma (MEC) of the breast is extremely rare and must be distinguished from MEC originating in the breast parenchyma. Histologically, MEC is characterised by the presence of both solid and cystic components and morphological identification of the three intermixed components of squamoid, intermediate, and mucin cells. Diagnosis may be difficult given the rarity of this disease, the variable clinical presentation and histological heterogeneity. Here we describe the first published case of primary multifocal MEC arising in the skin of the breast and masquerading as a breast mass. Cutaneous MEC may prone to recurrences so wide local excision with pathologic confirmation of tumour-free margins is appropriate and careful follow-up is recommended.
