Carcinoma de células basales. Presentación de un caso / Basal cell carcinoma. Case presentation

El carcinoma de células basales, tumor que deriva de las células que forman la capa basal de la epidermis, es el tipo de cáncer de piel más frecuente en seres humanos, y afecta generalmente a personas de edad avanzada. Se presenta el caso de una paciente de 90 años, con historia previa de carcinoma cutáneo en el hombro izquierdo, que acudió a consulta de oftalmología refiriendo aumento de volumen, irritación y enrojecimiento en el párpado inferior del ojo derecho. Al examen físico ocular se encontró una lesión en párpado inferior, cerca del canto interno, elevada, con un diámetro aproximado de 6-7 milímetros, ulcerada hacia el centro. El diagnóstico histopatológico informó carcinoma basocelular sebáceo, diferenciación de muy baja frecuencia de presentación, lo que motivó la realización de este informe.

Basal cell carcinoma, tumor which derives from the cells that constitute the epidermis basal layer, is the most frequent type of skin cancer and affects generally aged people. It is presented a case of a 90 year old patient, with previous history of cutaneous carcinoma on the left shoulder, presented to the opthalmology consultation complaining of volume increasing, irritation and redness in the lower eyelid of the right eye. On the physical examination it was found a lesion on the lower eyelid close the internal edge, elevated, with a diameter of 6-7 mm, ulcerated to the inside. The hist-pathological  diagnosis informed a sebaceous baso-cellular carcinoma, a differentiation of a very low frequency that motivated the presentation of this report.

A unique case of isolated sebaceous adenoma of the bulbar conjunctiva / Um caso único de adenoma sebáceo isolado de conjuntiva bulbar

ABSTRACT Our patient was a 34 year-old male who presented with a painless conjunctival mass that had developed 3 months before his first visit. On performing slit-lamp biomicroscopy, a lobulated pink-yellowish solid mobile mass was observed on the nasal bulbar conjunctival surface of his left eye. The tumor was excised, and histopathologic examination of the tumor revealed a sebaceous adenoma. Systemic examination was normal. No recurrence was observed during the 24-month follow-up period. Sebaceous adenoma of the bulbar conjunctiva is an extremely rare benign tumor, which may be observed to be isolated in the absence of malignancy.

RESUMO Nosso paciente era um homem de 34 anos que apresentou uma massa conjuntival indolor desde há 3 meses antes da primeira consulta. Na biomicroscopia por lâmpada de fenda, observa-se uma massa rosa-amarelada, sólida, móvel e lobulada na superfície conjuntival bulbar nasal, em seu olho esquerdo. O tumor foi retirado e o exame histopatológico demonstrou um adenoma sebáceo. O exame sistêmico era normal. Nenhuma recidiva foi observada durante os 24 meses de acompanhamento. Adenoma sebáceo da conjuntiva bulbar é um tumor benigno extremamente raro e pode ser visto isolado, sem quaisquer doenças malignas associadas.

Extra ocular sebaceous adenocarcinoma in HIV-positive patient - case report / Adenocarcinoma sebaceo extra-ocular em paciente HIV positivo - relato de caso

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.

Comportamiento de los tumores malignos de los párpados en el Instituto Nacional de Oncología y Radiobiología / Behavior of malignant eyelid tumors treated at the National Institute of Oncology and Radiobiology

Objetivo: evaluar el comportamiento clínico-histopatológico de los tumores malignos palpebrales y las modalidades de tratamiento aplicadas en el Instituto Nacional de Oncología y Radiobiología. Métodos: se realizó un análisis retrospectivo de 255 pacientes tratados consecutivamente en el periodo de enero 1995 a julio 2010. Los casos fueron evaluados según localización del tumor, modalidad de tratamiento, recurrencias, recidivas, complicaciones y sobrevida. El estadiamiento se realizó según los criterios de la la Unión Internacional contra el Cáncer como T1N0M0, T2N0M0, T3N0M0, T4N0M0. Resultados: del total de pacientes, 54,1 por ciento fueron masculinos y 45,9 por ciento femeninos con rangos de edad entre 18 y 80 años. La localización más frecuente fue en el párpado inferior (35 por ciento), y el canto externo, la variedad histopatológica predominante fue el carcinoma basocelular (47,8 por ciento). El tratamiento de elección fue la cirugía, la que se realizó a 198 pacientes. El 50,2 por ciento de los casos tratados tuvieron persistencia tumoral con infiltración de los bordes de sección quirúrgicos, los cuales recibieron tratamiento radiante adyuvante. Se presentaron recurrencias en el 3,5 porciento entre 3 y 5 meses y recidivas en el 7,1 por ciento de los casos, a partir del primer año después de terminado el tratamiento inicial, las complicaciones más frecuentes encontradas fueron los pobres resultados cosméticos, disminución de la visión, úlceras corneales, entre otras. La sobrevida fue de 86,3 porciento. Conclusiones: se hace necesaria la introducción de modernos y conservadores tratamientos como alternativa a la cirugía que sean capaces de controlar el tumor y mejorar la calidad de vida de los pacientes con cáncer palpebral en casos específicos

Objective: to evaluate the clinical and histopathological behavior of malignant eyelid tumors and the treatment options followed at the National Institute of Oncology and Radiobiology. Methods: a retrospective analysis of 255 patients consecutively treated from January 1995 to July 2010 was carried out. The cases were evaluated according to location of tumor, treatment modality, recurrence, relapse, complications and survival rate. The staging of each case followed the criteria of the International Union against Cancer such T1N0M0, T2N0M0, T3N0M0, T4N0M0. Results: of the total number of patients, 54.1percent were males and 45.9percent females with age ranging 18 to 80 years. The most frequent location was the lower eyelid (35percent) and the outer border, the predominant histopathological type was basocellular carcinoma (47.8 percent). The treatment of choice was surgery which was performed in 198 patients. In the study group, 50.2 percent of the treated cases showed tumoral persistence with infiltration of surgical section borders, which received adjuvant radiant treatment. Recurrences occurred in 3.5 percent of cases after 3 to 5 months and relapses appeared in 7.1 percent of patients after the first year of the end of the initial treatment. The most common complications were poor esthetic results, reduced vision, corneal ulcers and others. Survival rate was 86.3 percent. Conclusions: it is necessary to implement modern and conservative treatments as alternative to surgery, which may be able to control tumor and to improve the quality of life of specific eyelid cancer cases

Sebaceous carcinoma of the eyelid - different diagnostic times, different outcomes: case reports / Carcinoma de glândulas sebáceas palpebral - diferentes momentos de diagnósticos, diferentes resultados cirúrgicos: relatos de casos

Sebaceous carcinoma of the eyelid is a very rare slow-growing tumor and is considered an aggressive eyelid neoplasm. It can reach mortality rate of about 6 percent. Diagnosis is often delayed because of its ability to masquerade as other periocular lesions, both clinically and histologically. We present three cases of sebaceous carcinoma, with different surgical outcomes, showing the importance of early diagnosis.

Carcinoma sebáceo é um tumor raro de crescimento lento considerado uma das mais agressivas neoplasias palpebrais. Pode alcançar taxa de mortalidade de aproximadamente 6 por cento. O diagnóstico tardio é comum devido a sua habilidade de se confundir com outras lesões perioculares tanto clinicamente quanto histologicamente. Relatamos três casos de carcinoma sebáceo da pálpebra com diferentes resultados cirúrgicos, enfatizando a importância do diagnóstico precoce.

Carcinoma de Meibômio como segundo tumor em portadores de retinobastoma: relato de dois casos / Eyelid tumor in anophthalmic socket due to retinoblastoma: report of two cases

O retinoblastoma pode acometer um ou os dois olhos, ocorrendo de forma hereditária ou esporádica. O portador dessa doença pode desenvolver, a longo prazo, outros tipos de tumores não oculares. Relatamos dois pacientes: o filho, portador de cavidade anoftálmica bilateral após remoção dos olhos devido ao retinoblastoma, que apresentou segundo tumor palpebral unilateral, afetando a pálpebra superior; e o pai, portador de cavidade anoftálmica unilateral também por remoção de retinoblastoma e que apresentou tumoração de crescimento rápido na pálpebra superior ipsilateral ao olho enucleado. O exame imuno-histoquímico de ambas as lesões excisadas revelou que se tratava de carcinoma de glândulas sebáceas. Os pacientes evoluíram bem após a remoção do tumor palpebral e, até o momento, não apresentam sinais de recidiva ou metástase.

Retinoblastoma is a unilateral or bilateral intraocular tumor, occurring as a hereditary or sporadic tumor. Another not ocular lesion is a possibility for retinoblastoma carriers. The authors report the cases of two patients: a son with bilateral anophthalmic socket due to retinoblastoma, who presented unilateral upper eyelid tumor; and his father with unilateral anophthalmic socket secondary to enucleation due to retinoblastoma and a tumor growing fast in the upper eyelid at the same side of the anophthalmic cavity. Lesions were diagnosed as sebaceous carcinoma confirmed by immunohistochemical exam. Both patients had the eyelid tumors removed, with good resolution. None of them have presented either signs of recurrence or metastasis.

Carcinoma sebáceo palpebral: Presentación de un caso / Palpeebral sebaceous carcinoma: A case report

Se presenta a un paciente de 26 años de edad, con diagnóstico clínico de chalación gigante del párpado inferior del ojo derecho de 6 meses de evolución, con un gran componente inflamatorio y bordes ulcerados que no había respondido a la terapéutica médica ni quirúrgica. El resultado de la biopsia tomada de este lesión fue, carcinoma epidermoide infiltrante, por lo que decidimos hacer la cirugía con margen oncológico, que requirió de un colgajo libre del párpado superior con fines estéticos y funcionales. El estudio histológico de la tumoración evidenció un carcinoma sebáceo. La evolución posoperatoria de este paciente, al año de operado, ha sido satisfactoria.

A 26-year-old patient wich clinical diagnosis of giant chalazi on of the lower eyelid of the right eye with 6 months of evolution and with a great inflamatory component and ulcerated edges that had not responded to mechical and surgical therapeutics is presented. The result of the biopsy was infiltrating epidermoid carcinoma, so it was decided to perform surgery with oncological margin that required a free flap of the upper eyelid with aesthetic functional ends. The histological study of the tumor proved the existance of a sebaceous carcinoma. The posoperative evolution of the patient after a year has been satisfactory.
