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.

The finding of a sebaceous carcinoma in a mature teratoma is rare in human pathology, with fewer than 10 cases currently reported in the literature. In this article, we report a case of sebaceous carcinoma in a mature teratoma of the ovary in a 59-year-old patient and discuss its histological findings.

El cuerno cutáneo es un concepto semiológico. Se define como una lesión tumoral hiperqueratósica de aspecto cónico y tamaño variable, que puede tener como base una lesión de origen benigno, premaligno o maligno. El tratamiento consiste en la resección completa de la lesión, seguido de un estudio histopatológico para precisar el diagnóstico. El carcinoma sebáceo, neoplasia maligna derivada del epitelioanexial de las glándulas sebáceas, se ha descrito como una etiología poco frecuente de cuerno cutáneo. Su diagnóstico es difícil, ya que carece de elementos clínicos característicos y su histología puede ser similar al carcinoma espinocelular o basocelular, pero importante ya que constituye una neoplasia agresiva, con riesgo de recurrencia local y metástasis. A continuación, presentamos el caso de un hombre de 68 años con diagnóstico clínico de cuerno cutáneo palpebral y diagnóstico histopatológico de carcinoma sebáceo.
The cutaneous horn is a semiological concept. It is defined as an hyperkeratotic tumor of conical appearance and variable size, which may be based on benign, premalignant or malignant lesion. The treatment is the complete resection followed by an histopathology study to clarify the diagnosis. Sebaceous carcinoma, malignant neoplasm derived from adnexal epithelium of sebaceous glands, has been described as a rare etiology of cutaneous horn. Diagnosis is difficult because it doesnt have characteristic clinical features and histology may be similar to squamous or basal cell carcinoma, but it is important because is an aggressive neoplasm with risk of local recurrence and metastasis. We present a case of a 68-year-old man, with a clinical diagnosis of eyelid cutaneous horn and histopathological diagnosis of sebaceous carcinoma.

Sebaceous adenocarcinoma is a rare adnexal tumor that can affect the skin and is divided into ocular, a more common form and extra ocular, of a rarer occurrence. We report the case of a patient diagnosed with Acquired Immune Deficiency Syndrome (AIDS) who developed an extra ocular, bulky and fast-growing sebaceous adenocarcinoma on the face. The literature has suggested that transplanted patients and HIV-positive patients have an excess risk for developing adnexal tumors, including sebaceous adenocarcinoma.
Adenocarcinoma sebáceo é um tumor anexial raro que pode envolver a pele e é dividido em ocular, mais comum e extraocular, mais raro. Relatamos o caso de um paciente com diagnóstico de Síndrome da Imunodeficiência Adquirida que desenvolveu um adenocarcinoma sebáceo extra-ocular, na face, volumoso, de rápido crescimento. A literatura tem sugerido que pacientes transplantados e portadores do vírus da imunodeficiência humana têm um excesso de risco para o desenvolvimento de tumores anexiais, incluindo o Adenocarcinoma sebáceo.

We report a sebaceous carcinoma confined to the corneoscleral limbus without involvement of the eyelid. A 60-year-old man, who showed multiple masses on the corneaoscleral limbus and limbal ulceration but with normal eyelids, underwent surgical en-bloc excision of the masses. Histopathologic examination revealed a sebaceous carcinoma. Three weeks after excision, multiple pagetoid recurrences were found along the bulbar conjunctiva 2 mm away from the limbus. After the application of topical mitomycin C, the pagetoid spread regressed completely. After a 2 year follow-up, no other local or systemic recurrences were observed. This report shows that the ulcerative mass which is confined to only the corneoscleral limbus may be a sebaceous carcinoma even without eyelid involvement. Topical mitomycin C may be effective for treating pagetoid spread of sebaceous carcinoma of limbal origin.

El carcinoma sebáceo es un tumor maligno infrecuente derivado del epitelio de las glándulas sebáceas. Potencialmente puede desarrollarse de cualquier glándula sebácea, pero más comúnmente lo hace en el área periobitaria y de la cabeza y el cuello. Los carcinomas sebáceos extraoculares son tumores extremadamente raros, agresivos, malignos, con menos de 150 casos descritos.

Sebaceous carcinoma of the ocular adnexa is a malignant neoplasm which can exhibit aggressive local behavior and can metastasize to regional lymph nodes and distant organs. The neoplasm is known to masquerade as other benign and less malignant lesions, resulting in delay in diagnosis and relative high morbidity and mortality. Fine needle aspiration cytology (FNAC) of recurrent upper eyelid nodules treated elsewhere as chalazion was done. Cytological smears were suggestive of malignancy. Subsequently histopathology confirmed the diagnosis of sebaceous gland carcinoma. Eyelid reconstruction was done after histopathologically confirmed tumor-free margins. The article highlights the role of FNAC in early diagnosis and subsequent appropriate surgical management of eyelid sebaceous gland carcinoma to prevent recurrence and metastasis.

El carcinoma sebaceo es una neoplasia maligna poco frecuente de observar, constituída por células que muestran una diferenciación hacia el epitelio sebaceo. Suele presentarse a finales de la séptima década de la vida, con cierto predominio en mujeres y en la raza asiatica. De acuerdo con su localización, se distinguen 2 variedades: ocular y extraocular. La primera es la mas frecuente y se origina de las glandulas sebaceas presentes en los anexos óculo-palpebrales, siendo el parpado superior la localización mas común. Se caracteriza por un comportamiento agresivo, con diseminación directa y alto potencial metastasiante regional y a distancia. La segunda variedad es aún mas rara, menos agresiva y se localiza en cabeza y cuello, siendo la glandula parótida la zona mas comprometida. La patogénesis es incierta, pero los procesos inflamatorios crónicos, la radiación ultravioleta y la radioterapia favoreceran su desarrollo. El carcinoma sebaceo cutaneo es un tumor versatil, que se presenta con diferentes aspectos clínicos y distintos patrones histológicos de crecimiento, que retardan el diagnóstico definitivo. El tratamiento de elección es la cirugía con margenes amplios. Presentamos 4 pacientes con carcinomas sebaceos extraoculares y realizamos una revisión de la literatura
