We report an original case of carcinoma en cuirasse associated with zosteriform metastasis. A 40-year-old woman presented to our department with painful erythematous lesions. She had a history of invasive ductal carcinoma of the left breast. Numerous erythematous, papules and whitish vesicles were present over the right side of the chest in a dermatomal distribution with indurated coalescent plaques. Biopsy revealed metastatic carcinoma of breast origin. Breast mammography showed suspicious right nodule. Controlateral breast carcinoma with CM was diagnosed. CM show a wide range of clinical manifestations. Carcinoma en cuirasse, is a very rare form of metastatic cutaneous breast cancer. It is characterized by diffuse sclerodermatous induration of the skin. Zosteriform metastasis is also rarely seen. It may be distributed along dermatomeres in a variety of clinical patterns, including nodular, papulovesicular, or vesiculobullous. In our case, the zosteriform metastasis occurred in the contralateral site. It announced the developing of contralateral breast cancer.
Breast cancer is the first cancer associated with cutaneous metastasis (CM). The clinical presentation of these metastases is comprehensive. We report an original case of carcinoma en cuirasse associated with zosteriform metastasis that indicates the development of contralateral breast cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
