Abstract
Carcinoma en cuirasse is a rare form of cutaneous metastasis characterized by the spread of a primary malignant tumor to the skin, most commonly associated with breast cancer in women. It may present as papulonodular lesions, erysipeloid, sclerodermiform infiltration, or en cuirassed, typically appearing months or years after the initial diagnosis of the primary malignancy. Diagnosis of carcinoma en cuirasse can be challenging, but histology can help distinguish it from other skin conditions. Treatment options for carcinoma en cuirasse are not well-defined due to the limited number of reported cases. Here, we report a case of a 30-year-old female, who presented with invasive ductal carcinoma which presented as carcinoma en cuirasse with a spoke-wheel pattern over the course of 6 months.
