Sebaceous breast carcinoma

ABSTRACT Breast sebaceous carcinoma is one of the rarest breast neoplasms, with less than 30 cases reported worldwide. Due to the rarity, the new WHO classification of breast tumors grouped these tumors among the ductal carcinoma. A detailed description of these cases is relevant due to the insufficient knowledge about the prognosis of this neoplasm. We report the clinical, histological, and immunohistochemical characteristics of a case of sebaceous carcinoma of the breast in an 81-year-old woman with a right breast nodule. The tumor was composed of nests of a varying mixture of sebaceous cells with abundant slightly vacuolated cytoplasm, surrounded by smaller oval-to-fusiform cells with eosinophilic cytoplasm without vacuolization. No lymph node metastases were present. The immunohistochemical reactions were positive for GATA3, EMA, CD15, and GCDFP15 (focal staining), and negative for RE, RP, and HER-2. The tumor was classified as triple-negative. Morphologically, the differential diagnoses included skin sebaceous carcinoma, lipid-rich carcinoma, apocrine carcinoma, and glycogen-rich clear cell carcinoma. Most of the previously reported cases were positive for RE and RP, which generally was associated with a better prognosis. However, some cases presented a more aggressive behavior with distant and lymph node metastases.

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.

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.
