Background: Mucoepidermoid carcinoma (MEC) breast is a very rare triple negative breast cancer with relatively better overall prognosis. They have histomorphological and immunohistochemical features similar to the salivary gland MEC. Literature suggests that they also carry molecular characteristics similar to the salivary gland MEC.

Case Presentation: A 73-years-old woman presented with complaints of painful, foul smelling pus discharging mass in right breast. Patient underwent therapeutic incision and drainage along with diagnostic biopsy. On histopathology, diagnosis of MEC, high grade was made.

Conclusion: Primary MEC is a very rare triple negative breast cancer (TNBC) usually with much better survival outcome in comparison to other TNBCs. However, the index case had locally advanced disease with unique presentation leading to an alternative initial management.
