ABSTRACT

RESUMEN El carcinoma sebáceo es una neoplasia anexial poco común que puede originarse en cualquier lugar del cuerpo donde existan glándulas sebáceas, siendo la principal ubicación la cabeza y el cuello, existiendo la presentación ocular y extraocular. Alcanza entre 0,2% a 4,6% de todas las neoplasias cutáneas malignas, con mayor incidencia en los adultos mayores caucásicos. La presentación clínica habitual corresponde a un nódulo duro o quístico subcutáneo eritematoso o amarillento, indoloro, de crecimiento acelerado. Sin embargo, puede manifestarse como una amplia gama de lesiones cutáneas, lo que, agregado a su baja incidencia, sea altamente subdiagnosticado. Se presenta el caso de un paciente de 64 años con tumor exofítico malar izquierdo con ulceraciones y áreas de necrosis en la superficie, sin compromiso de párpado inferior, de agudeza visual ni motilidad ocular. Se realiza resección del tumor, cuya biopsia definitiva confirma diagnóstico de carcinoma sebáceo extraocular.


ABSTRACT Sebaceous carcinoma is a rare anexal neoplasm that can develop on any part of the body containing sebaceous glands, but nearly the 70% of sebaceous carcinoma occur on the head and neck, being two ways of presentation, ocular and extraocular. It represents 0.2-4.6 % of all malignant neoplastic cutaneous lesions, whit a peak incidence in the eighth decades of life, in caucasian people. Typical clinical presentation of sebaceous carcinoma is a painless, firm or cystic subcutaneous nodule described as pink to red-yellow, however clinical features can be quite varied, which added to its low incidence leads to the diagnosis is often delayed for months to years. We present the case of a 64 years old patient whit an exofitic malar tumor ulcerated and necrotic in the surface, without compromising the lower eyelid, vision or ocular mobility. The biopsy of the tumor resection shows an extraocular sebaceous carcinoma.
