Carcinoma en cuirasse with Zosteriform Metastasis-A Rare Presentation of Breast Carcinoma

Carcinoma en cuirasse is a form of cutaneous metastasis of breast carcinoma. Although a rare condition, it is most commonly associated with breast carcinoma with local recurrence after mastectomy and metastasis occurs a few months to years after primary has been diagnosed. Less frequently a metastasis is diagnosed at the same time as primary tumour is diagnosed. We report a case of carcinoma en cuirasse in a 60 year old female who presented with elevated nodular indurated skin lesions on anterior and posterior left chest wall and axillary region. FNAC of lesions was performed. It was diagnosed as metastatic deposits of Duct Cell Carcinoma. It was followed by histopathology and the diagnosis was confirmed. Hence it is very important to investigate thoroughly keloid like or indurated patches on skin of long duration.
