Carcinoma en cuirasse

Carcinoma en cuirasse is a rare form of metastatic cutaneous breast cancer. We report a typical case of cancer en cuirasse in a 36 years old female who presented with diffuse erythema and scaly nodular lesions over the left breast, axilla, neck and arm. Imaging revealed a lump in upper-outer quadrant of affected breast. Histopathological examination of the cutaneous nodules and fine needle aspiration cytology of the breast lump revealed features of infiltrating ductal cell carcinoma.
