A Case of Carcinoma en Cuirasse from Thyroid Cancer / 대한피부과학회지

ABSTRACT

A 52-year-old male had presented with painful swelling on the left shoulder. The lesion had progressed to involve the left chest, neck, and arm, and 3 months later, evolved into brown to light purplish hard plaque mimicking the feature of scleroderma. A skin biopsy findings were consistent with metastatic carcinoma, and neck MRI and thyroid sonogram revealed primary thyroid cancer of left lobe. The patient's condition was carcinoma en cuirasse, an uncommon clinical feature of metastatic skin cancer. Skin metastasis of thyroid cancer is rare, and to our knowledge, there is not any documented case of carcinoma en cuirasse from thyroid cancer. We present a case of carcinoma en cuirasse from thyroid cancer.
