ABSTRACT
Introducción: El cáncer de mama es uno de los tumores malignos más frecuentes en mujeres, y representa el principal carcinoma que genera metástasis cutáneas (MC), excluyendo al melanoma. Objetivos: Realizar una revisión de las MC del carcinoma mamario y mostrar las principales formas de presentación clínica. Discusión: Las MC pueden presentarse mediante diferentes manifestaciones dermatológicas, aunque lo más frecuente es un infiltrado eritematoso papulonodular único o múltiple, generalmente localizado en la piel subyacente o próxima al área del tumor primario. Las células tumorales alcanzan la piel por 3 vías de diseminación: hemática, linfática y por contigüidad. Los carcinomas mamarios, normalmente, se diseminan por la vía linfática y llegan a zonas de la piel cercanas; así, las MC de mama adoptan como sitio de implantación principal la piel del tórax. Conclusiones: Las MC pueden ser la manifestación inicial de un cáncer, o bien un signo de recurrencia de este. Es necesario tener un alto nivel de sospecha diagnóstica debido a su gran polimorfismo clínico.
Introduction: Breast cancer is one of the most frequent malignant tumors in women and is the main carcinoma leading cutaneous metastasis (CMs), excluding melanoma. Objectives: To present a literature review about CMs from breast cancer and to show the mainly clinical forms. Discussion: CMs can present different skin manifestations, but single or multiple papulonodular erythematosus infiltrate are the most common, generally located in the underlying skin or close to the primary tumor area. Tumor cells reach the skin through three dissemination forms -hematogeneus, lymphatic, and contiguity-. Breast carcinomas normally disseminate through lymphatic via and reach close skin zones; thus, breast CMs mainly allocate in the thorax skin. Conclusions: CMs can be the initial manifestation of a cancer or a sign of its recurrence. There must be a high level of suspicion because its clinical polymorphism.

INTRODUCTION: Cutaneous metastases represent 2% of all metastases. Breast cancer is the most common cause of skin metastases. Schwartz described 8 types of cutaneous breast metastases; one uncommon form is carcinoma telangiectodes (CT), which may resemble angiosarcoma or lymphangioma circumscriptum. However, there are no reports of CT misdiagnosed as eruptive angiokeratomas. CASE REPORT: The authors describe the clinical, histopathologic, and immunohistochemical features of a unique case of CT. Clinical examination revealed an itchy, dark blue-reddish scaly papular eruption that resembled angiokeratomas. The papules were grouped in a zosteriform pattern on the right chest. A biopsy of the papules revealed intravascular thrombi of neoplastic cells and erythrocytes. The neoplastic cells were pleomorphic and with mitotic figures. Immunohistochemical analysis revealed expression of HER-2-neu in neoplastic cells but negative for estrogen and progesterone receptors. The involved vessels were positive for CD31 and negative for podoplanin. This immunoprofile demonstrated intravascular spread of aggressive breast carcinoma. CONCLUSION: CT is an uncommon form of cutaneous metastasis from breast carcinoma with less than 10 cases described in the literature. There are no previous reported cases of CT mimicking angiokeratomas, although lymphangioma circumscriptum-like lesion may occasionally resemble angiokeratomas. A unique clinical presentation of CT is described.
