Sebaceoma: hallazgos dermatoscópicos a propósito de dos casos / Sebaceoma: dermatoscopic findings at purpose of two cases

El sebaceoma es una neoplasia sebácea benigna inusual, que inicialmente se denominaba epitelioma sebáceo, lo que generaba confusión respecto a su biología tumoral, dado que histopatológicamente no presenta diferenciación suficiente como el adenoma sebáceo y tampoco es tan indeferenciado como el carcinoma sebáceo. Su diagnóstico precoz tiene gran relevancia, dado que, junto con el adenoma sebáceo y el carcinoma sebáceo, tienen una asociación directa con el síndrome de Muirr-Torre y, por lo tanto, con el desarrollo de cáncer de colon, endometrio, entre otros. En este punto, el uso de la dermatoscopia es muy importante. Considerando los pocos reportes en la literatura sobre la dermatoscopia en sebaceomas, presentamos dos casos clínicos en adultos, donde se destaca la presencia de estructuras amarillas homogéneas y vasos en corona o arboriformes.

Sebaceoma is an unusual benign sebaceous neoplasm, initially known as sebaceous epithelioma, which generated confusion regarding its tumor biology, given that it is histopathologically less differentiated than sebaceous adenoma, but with a higher differentiation than sebaceous carcinoma. Early diagnosis becomes relevant, given that together with sebaceous adenoma and sebaceous carcinoma, there is a direct association with Muirr-Torre syndrome and therefore the development of colon and endometrial cancer, among others. Because of this, the use of dermatoscopy becomes very important. Given the few reports in the literature on dermatoscopy in sebaceomas, we present two clinical cases, where the presence of homogeneous yellow structures and crown or arboriform vessels stands out.

Sebaceoma on the scalp simulating a malignant pigmented neoplasia.

The correct identification of pigmented nodular lesions of the scalp is often challenging. Despite the importance of clinical patterns and dermoscopy, important adjuvant tools that are usually helpful, their interpretation sometimes is not clear-cut. Here, the authors discuss a case of sebaceoma mimicking a malignant pigmented neoplasia, with conclusive histopathology.

Cuerno cutáneo y carcinoma sebáceo: diagnóstico diferencial a propósito de un caso / Cutaneous horn and sebaceous carcinoma: differential diagnosis of a case report

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 doesn’t 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.

Giant extraocular sebaceous carcinoma: case report and a brief review of a literature.

Extraocular sebaceous carcinoma (ESC) is a rare, aggressive malignant tumor that originates from the adnexal epithelium of the sebaceous gland. We present herein one of the largest cases reported in the literature until now. We also review briefly the relevant aspects including clinical presentation, differential diagnosis, histopathological features, inmunohistochemical profile, and therapeutic options.

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

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.

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.

Immunohistochemistry screening of sebaceous lesions for Muir-Torre syndrome in a 26-year period in a Mexican population.

Muir-Torre syndrome (MTS) is an autosomal dominant genodermatosis defined as the association of rare sebaceous gland skin tumors, keratoacanthomas, and a personal or familial history of malignant visceral tumors. Germline mutations in certain mismatch repair genes (MMR) have been identified in MTS families and their identification is a cornerstone for diagnosis of MTS. We reviewed our series of sebaceous neoplasms and performed immunohistochemistry (IHC) in order to screen for new MTS cases. Sebaceous neoplasms and visceral tumors from the same patient diagnosed between 1980-2006 were included. Immunohistochemistry to determine the presence or absence of MMR gene products in skin and visceral tumors was performed with mouse monoclonal antibodies anti-MSH2, anti-MSH6 and anti-MLH1. Six sebaceous neoplasms were identified in six females. Four patients presented a lack of expression of at least one of the MMR proteins in visceral and cutaneous neoplasms, thus warranting the diagnosis of MTS. Immunohistochemistry is a useful and accessible technique for the characterization of MMR gene expression in patients with sebaceous neoplasms.

Intraoral sebaceous carcinoma.

Intraoral sebaceous carcinoma (SC) is a rare tumour in the oral cavity thought to arise from malignant transformation of oral sebaceous glands. To our knowledge, only six cases of intraoral SC have been reported in the English language literature. The purpose of the present article is to report an additional case and review the literature.

[Sebaceous gland carcinoma of the eyelids]. / Carcinoma de glándulas sebáceas de los párpados.

Sebaceous gland carcinoma is considered a relatively rare tumor and represents approximately 1 and 5% of all eyelid tumors. These tumors usually arise in the Meibomian glands of tarsus, in the Zeis glands, and the sebaceous glands of caruncle or eyebrow. In some instances it had multicentric origin, while in other cases the initial location was unable to be determined. It occurs more frequently in women than in men and presentation age varies from 50 to 90 years. Clinical diagnosis is difficult because is can be confused with chalazion, blepharoconjunctivitis, conjunctivitis, and basocellular carcinoma. Sebaceous gland carcinoma could go unnoticed; thus, it is necessary to carry out excision of conjunctiva as well as to inform the pathologist of the possibility of malignancy, because pagetoide spread can be easily incorrectly interpreted or not observed even by expert pathologists (up to 50%). Five-years mortality has been estimated at 30% due delayed diagnosis and treatment. The present work intends to describe incidence, and clinical and histopathologic presentation of sebaceous gland carcinoma during the last 40 years at the Dr. Luis Sanchez Bulnes Hospital, Association to Prevent Blindness in Mexico, as well as to review treatment modalities forecast for this entity.

Carcinoma sebáceo de los párpados (carcinoma de glándula de Meibomio). Correlación clínico-patológica / Meibomian gland carcinoma. Clinicopathological correlationship

El carcinoma sebáceo es relativamente frecuente en los párpados y raro en otras localizaciones. Representa la segunda neoplasia maligna en los párpados. Se presenta después del quinto decenio de la vida. La incidencia es discretamente mayor en las mujeres. Es un tumor maligno con un alto grado de mortalidad. Es recidivante, invasor y metastatisante. Los aspectos histopatológicos más importantes para el diagnóstico son el grado de diferenciación, multicentricidad, invasibilidad, invasión pagetoide, dimensiones y metástasis. En la clínica puede confundirse con procesos inflamatorios y retrarse el diagnóstico, lo que agrava el pronóstico. El tratamiento ideal es quirúrgico en forma temprana y seguido por radio y quimioterapia
