Rare Presentation of En Cuirasse Detected on 18-F FDG PET/CT in a Case of Recurrent Breast Carcinoma.

ABSTRACT

Carcinoma en cuirasse is a type of cutaneous metastasis from different malignancies. En cuirasse although is a rare entity, most commonly occurs in cases of recurrent breast carcinoma after surgery or very rarely months or years after diagnosis of primary tumor. We report a rare case of neck carcinoma en cuirasse in a 47-year-old Indian female who is a known case of recurrent carcinoma left breast postmodified radical mastectomy, chemotherapy, and radiotherapy referred for fluorodeoxyglucose positron emission tomography-computed tomography following another six cycles of chemotherapy for response assessment.
