Erysipelatoid Carcinoma

SUMMARY Erysipelatoid Carcinoma (EC), also known as Inflammatory Metastatic Carcinoma, is a rare form of cutaneous metastasis, secondary to an internal malignancy, more often related to breast cancer. Clinically, the lesion has a well-marked, bound erythematous appearance, much like an infectious process, such as erysipelas and cellulitis, these being the most common differential diagnoses. It is characterized by an acute or subacute appearance with an erythematous plaque, sometimes hot and painful, being more often situated in the primary tumor vicinity, especially in the thorax wall in the region of a mastectomy due to breast cancer. Here we present the case of a 75-year-old patient with ductal infiltrated carcinoma for 3 years, who presented an acute erythematous and infiltrated plaque in the region of a previous mastectomy, with a final diagnosis of EC.

Cutaneous metastases in a patient with no previous diagnosis of cancer: diagnostic challenge

Abstract: On rare occasions, skin lesions are the first local of metastatic manifestation of internal malignancies. In case of no previous diagnosis of these tumors, the approach of suspicious skin lesions becomes a challenge, especially in differentiating cutaneous metastases and adnexal primary neoplasms. Currently, besides epidemiologic, dermoscopic and histopathologic aspects, the evaluation also integrates immunohistochemical exams and cell markers such as p40 and p63, highly specific for skin metastases. This article describes the case of cutaneous metastases as the sole obvious sign of breast cancer in a previously asymptomatic woman. The diagnosis was made by the finding of neoplastic cells in the dermis and immunohistochemistry compatible with ductal carcinoma.

Breast cancer metastasis to the pituitary gland / Metástase de câncer de mama para a hipófise

Metastatic tumors to the pituitary gland are an unusual complication typically seen in elderly patients with diffuse malignant disease. Breast and lung are the commonest sites of the primary tumor. Prognosis of patients with breast cancer metastasis is poor and depends on the primary neoplastic extension. We report a 54 year-old woman with breast cancer metastasis to the pituitary stalk first diagnosed because of visual disturbance with no other symptoms. Pituitary gland stalk metastasis is a very uncommon find and this case report includes a literature review.

Os tumores hipofisários malignos são raros e geralmente se constituem de metástases de neoplasias disseminadas. Câncer de mama e pulmão são os sítios primários mais frequentes e o prognóstico depende do grau de comprometimento da doença. Este é o relato do caso de uma mulher de 54 anos que apresentou uma lesão tumoral restrita à haste hipofisária, que se revelou como metástase do câncer de mama previamente conhecido. O acometimento da haste hipofisária é muito raro, motivo pelo qual descrevemos o caso com a revisão da literatura específica.

Breast carcinoma en Cuirasse - case report / Carcinoma de mama em couraca - relato de caso

Cutaneous metastasis is a phenomenon that results from a tumor spreading via lymphatic or vascular embolization, direct implant during surgery or skin involvement by contiguity. The primary malignant tumor that most commonly metastasizes to the skin in women is breast cancer, which can be manifested through papulonodular lesions, erysipeloid or sclerodermiform infiltration, en cuirasse. We report the case of a female patient, 78 years old, with papular, scaly and confluent lesions in the right breast for one year, progressing to edema and skin infiltration, reduction of breast volume and plaque en cuirasse, and similar lesions in the contralateral breast and abdomen for four months. The pathological diagnosis was invasive ductal breast carcinoma with Paget-like foci, epidermal skin metastases and lymphatic embolization.

A metástase cutânea é conseqüente à disseminação do tumor por embolização linfática, vascular, implantação direta durante cirurgias ou envolvimento da pele por contiguidade. Em mulheres, o tumor maligno primário que mais comumente metastatiza para a pele é o de mama, que tanto pode se expressar por lesões tumorais papulonodulares, infiltração erisipelóide ou esclerodermiforme, em couraça. Relatamos o caso de paciente do sexo feminino, 78 anos, apresentando lesões nodulares, descamativas e confluentes em mama direita, evoluindo com edema e infiltração cutânea, com redução do volume mamário e placa endurecida ilimitada. Invasão da mama contralateral e abdome ocorreram 4 meses após o início dos sinais. O diagnóstico histopatológico foi de adenocarcinoma ductal invasivo de mama com focos pagetóides epidérmicos e embolização linfática.

The prevalence and significance of oestrogen receptor (ER) positivity in breast cancer at the University Hospital of the West Indies, Jamaica / Prevalencia y significación de la positividad del receptor de estrógeno (RE) en el cáncer de mama en el Hospital Universitario de West Indies, Jamaica

OBJECTIVE: To identify the prevalence of oestrogen receptor (ER) positivity, and determine the relationship of ER status with patient and tumour characteristics, in patients with breast cancer. SUBJECTS AND METHODS: A retrospective review was conducted regarding the prevalence and clinical significance of ER in patients with breast cancer at the University Hospital of the West Indies (UHWI). Oestrogen receptor status results of 243 patients treated at UHWI were collected for the period January 1, 2002 to December 31, 2009. One hundred and ninety-nine were available for review. RESULTS: Oestrogen receptor status was positive in 125 (63%) and negative in 74 (37%) patients. Mean age at diagnosis was 52.6 ± 13.0 years for the ER positive group and 58.5 ± 14.23 years for the ER negative group. Postmenopausal women accounted for 55.2% and 64.9% of the ER positive and negative groups, respectively. Mean BMI was 28.0 kg/m² and 29.6 kg/m² for the ER positive and negative groups, respectively. Menarche occurred mainly between ages 12 and 13 years for both groups. Mean age at 1st parity was 23.4 years for the ER positive and 21.4 years for the ER negative group with median parity of two for both groups. The most prevalent risk factors were oral contraceptive pill (OCP) use (24.3% for the ER positive group, 17.1% for the ER negative group), family history of breast cancer (12.0%; 13.4%) and previous smoking (8.4%; 6.9%). Tumour node metastasis (TNM) stage was Stage II in most cases (46%; 49%). Infiltrating ductal histology was most common (81.5%; 87.7%). Her 2/ neu status was negative for most patients (91.3%; 91.5%). Most patients were disease free (77.6%; 70.0%) after an average follow-up period of 3.5 years. More persons in the ER negative group had locoregional recurrence (8%) and metastases (22%). CONCLUSIONS: Oestrogen receptor positive cohort was more prevalent. The ER negative group was older (p = 0.003).

OBJETIVO: Identificar la prevalencia del receptor de la positividad de receptor de estrógeno (RE), y determinar la relación del estatus de RE con el paciente y las características del tumor, en las pacientes con cáncer de mama. SUJETOS Y MÉTODOS: Se realizó un estudio retrospectivo con respecto a la prevalencia e importancia clínica del RE en los pacientes con cáncer de mama en el Hospital Universitario de West Indies (UHWI). Se recogieron los resultados del estatus del receptor de estrógeno de 243 pacientes tratados en UHWI en el periodo del 1 de enero de 2002 al 31 de diciembre de 2009. Ciento noventa y nueve estuvieron disponibles para examen. RESULTADOS: El estatus del receptor de estrógeno fue positivo en 125 (63%) y negativo en 74 (37%) pacientes. La edad promedio al momento del diagnóstico fue 52.6 ± 13.0 años para el grupo de RE positivo y 58.5 ± 14.23 años para el RE grupo negativo. Las mujeres menopáusicas representaron el 55.2% y el 64.9% del RE de los grupos positivos y negativos respectivamente. El índice de masa corporal (IMC) promedio fue 28.0 kg/m2 y 29.6 kg/m2 para el RE de los grupos positivos y negativos respectivamente. La menarquia ocurrió principalmente entre las edades de 12 y 13 años para ambos grupos. La edad promedio en la primera paridad fue 23.4 años para el grupo de RE positivo y 21.4 años para el de RE negativo, siendo la paridad mediana igual a dos para ambos grupos. Los factores de riesgo de mayor preponderancia fueron el uso de anticonceptivos orales (ACO) (24. 3% para el grupo de RE positivo, 17.1% para el grupo RE negativo); historia familiar de cáncer de mama (12.0%; 13.4%); y hábito de fumar con anterioridad (8.4%; 6.9%). De acuerdo con la estadificación tumor-nódulo-metástasis (TNM), se trataba de la Etapa II en la mayor parte de los casos (46%; 49%). La histología ductal infiltrante fue la más común (81.5%; 87.7%). El estatus Her2/neu fue negativo para la mayoría de las pacientes (91.3%; 91.5%). La mayoría de las pacientes se hallaban libres de enfermedad (77.6%; 70.0%) después de un periodo promedio de seguimiento de 3.5 años. En el grupo de RE negativo había más personas con recurrencia locoregional (8%) y metástasis (22%). CONCLUSIONES: La cohorte positiva del receptor de estrógeno positiva fue más prevaleciente. El grupo negativo de RE fue de mayor edad (p = 0.003).

Clinical significance of matrix metalloproteinase 2 and 9 in breast cancer.

Background: Invasion and metastasis are the most strenuous problems in the management of breast cancer. These events require diverse proteolytic enzymes, among which MMP-2 and MMP-9 play a significant role in degradation of type IV collagen, the major component of the basement membrane. Therefore, the major objective of the study is to evaluate the clinical usefulness of MMP-2 and MMP-9 with respect to malignant tumor growth, invasion, and metastasis in breast cancer. Materials and Methods: Gelatin zymography was performed on 157 tissue extracts of malignant and adjacent normal breast tissues as well as negative and positive lymph nodes from 49 breast cancer patients. Statistical analysis was carried out using SPSS statistical software (version 10). Results: ProMMP-2 levels were significantly higher in adjacent normal tissues. Active MMP-2 and MMP-9 levels were higher in malignant breast tissues. Activation ratios of MMP-2 and MMP-9 were significantly higher in malignant breast tissues and in patients with lymph node metastasis. ProMMP-2, active MMP-2, and active MMP-9 could significantly discriminate between malignant and adjacent normal breast tissues. The MMP-2 activation ratio showed significant discriminatory efficacy between patients with and without lymph node metastasis and significant association with increased risk of lymph node metastasis in node-negative patients. Conclusion: The results indicate significant clinical utility of these proteolytic enzymes in malignant tumor growth, invasion, and metastasis in breast cancer.

Metastatic eyelid disease associated with primary breast carcinoma: case report / Doença metastática palpebral associada a carcinoma primário de mama: relato de caso

Metastasis confined to eyelids are rare, representing less than 1 percent of malignant eyelid lesions. More than 50 percent of all eyelid metastasis are reported to have the breast as the most common primary origin. Two cases of metastatic eyelid disease associated with primary breast carcinoma are described. These lesions were the first sign of metastatic systemic disease. Case 1: An 80-year old woman with no significant ophthalmological history complaining of a discrete painless lesion in the left upper eyelid. She had been diagnosed 10 years before as infiltrated ductal carcinoma of right mammary gland with no reference of metastatic disease. Case 2: A 77-year old woman who attends our ophthalmology service came complaining of a four-month history of a painless swelling and erythema of right lower eyelid. The past medical history was significant for infiltrated ductal carcinoma on right mammary gland 2 years before the ocular manifestation. Breast carcinoma is notorious for its presentation diversity. Metastatic disease should be considered as differential diagnosis of eyelid lesions. Although rare, these lesions can be an initial sign of systemic malignancy.

Metástase confinada às pálpebras é rara, representando menos de 1 por cento das lesões malignas palpebrais. Mais de 50 por cento das metástases palpebrais são relatadas como tendo a mama como sítio primário. Relatamos dois casos de doença metastática palpebral associada a carcinoma primário de mama. Estas lesões foram o primeiro sinal de doença metastática sistêmica. Caso 1: Paciente do sexo feminino, 80 anos de idade sem antecedentes oftalmológicos apresentando discreta lesão nodular indolor na pálpebra superior do olho esquerdo. O carcinoma ductal de mama foi diagnosticado há 10 anos sem doença metastática. Caso 2: Paciente do sexo feminino, 77 anos de idade, com queixa de edema indolor e hiperemia na pálpebra inferior do olho direito há quatro meses. Apresentava antecedente pessoal de carcinoma ductal infiltrativo de mama diagnosticado há dois anos, sem doença metastática. O carcinoma de mama é notório por sua diversidade na apresentação clínica. A doença metastática deve ser considerada no diagnóstico diferencial das lesões palpebrais. Embora raras estas lesões podem ser o primeiro sinal da doença sistêmica.

Marcadores moleculares em câncer de mama preditivos de metástases axilares / Molecular features of breast cancer predictive of lymph node metastases

OBJETIVO: Avaliar e relacionar fatores morfológicos e moleculares de câncer de mama preditivos de metástases em linfonodos axilares. MÉTODOS: Selecionamos 123 casos de carcinomas mamários invasores subdivididos em três grupos de acordo com o status axilar (pacientes com macrometástases, com micrometástases e linfonodo-negativas). Avaliamos e correlacionamos a presença de metástases axilares com fatores morfológicos (tamanho do tumor, tipo e grau histológicos, invasão linfática e sangüínea em lâminas coradas pela hematoxilina e eosina) e moleculares do tumor primário (receptores de estrógeno e progesterona, Ki67, p53, E-caderina, Her2, e invasão linfática e sangüínea em lâminas coradas pela imunoistoquímica, para D2-40 e CD31). RESULTADOS: A ocorrência de metástases axilares esteve positivamente relacionada à embolização neoplásica em vasos linfáticos em lâminas coradas pela hematoxilina e eosina (HE), quando analisamos os casos com metástases e sem metástases (p=0,04), e, quando eles eram analisados em três subgrupos (p=0,002). Também identificamos relação positiva e estatisticamente significativa entre a presença de metástases axilares e invasão de vasos sangüíneos em lâminas coradas pelo CD31 (p=0,02). As demais variáveis moleculares e morfológicas não mostraram relação estatisticamente significativa com a presença de metástases. CONCLUSÃO: A invasão neoplásica em vasos linfáticos e sangüíneos identificadas em cortes histológicos corados pela HE e por marcadores imunoistoquímicos relaciona-se positivamente com a ocorrência de metástases, e é preditivo de metástases em linfonodos axilares em câncer de mama.

OBJECTIVE: The aim of our study was to analyze morphologic and molecular markers of breast cancer relating them to the presence of metastases in axillary lymph nodes. METHODS: We selected 123 cases of invasive mammary carcinomas stratified into three subgroups: with macrometastases, with micrometastases, and lymph node negative. Presence of metastases was evaluated relating them with morphologic factors (size of primary tumor, type and grade, presence of lymphatic and blood vessel invasion in hematoxylin and eosin-stained slides) and molecular factors of primary tumor (estrogen and progesterone receptors, E-cadherin, Ki67, p53, Her2 expression, and the presence of lymphatic and blood vessel invasion in immunostained sections for D2-40 and CD31). RESULTS: Axillary lymph node metastases were positively related to the presence of lymphatic vessel invasion in hematoxylin and eosin (H&E)-stained slides, when analyzed with or without metastases (p=0.04) and when analyzed in the three subgroups (p=0.002). Lymph node metastases were also positively related to presence of blood vessel invasion identified by immunohistochemistry (IHC) for CD31 (p=0.02). However other morphologic and molecular factors were not related to the presence of axillary node metastases. CONCLUSION: Lymphatic and blood vessel invasion identified in H&E and IHC-stained slides are positively related to the rmetastatic status of axillary lymph nodes and are predictive of axillary lymph node metastases in breast cancer.

A Case of Diode Laser Photocoagulation in the Treatment of Choroidal Metastasis of Breast Carcinoma

To report a single case of improvement on choroidal metastasis of breast cancer after laser photocoagulation. A 52-year-old female patient who complained of visual disturbance of the right eye with multiple states of metastasis of breast carcinoma. On initial examination, the right best-corrected visual acuity was 0.63. Right fundoscopy revealed an elevated mass-like lesion temporal to the macule with serous retinal detachment. The mass had a 3.5-disc diameter. A right fluorescein angiogram revealed hypofluorescence during the prearterial and arteriovenous phase and hyperfluorescence during the venous phase. The venous phase showed almost total masking of background choroidal fluorescence at the elevated lesion because of leakage and neovascularization. The patient was treated 4 times by diode laser photocoagulation in addition to chemotherapy. Fifty days after the diode laser treatments, the funduscopy examination and fluorescein angiogram revealed that the serous retinal detachment had been absorbed, the choroid had become flat, the lesion had been reduced in size and hyperfluorescence. The right best-corrected visual acuity was improved to 0.8. Laser photocoagulation appears not to cause any problems for the patient and may be an efficient treatment for patients with choroidal breast carcinoma.

Metástases pulmonares em homem: localização incomum do tumor primário / Pulmonary metastases in men: primary tumor in an unusual location

Os autores relatam caso de câncer de mama em um homem de 72 anos achado acidentalmente durante a pesquisa do tumor primário para investigação de metástases pulmonares. São abordados aspectos epidemiológicos, diagnóstico, tratamento e prognóstico desta patologia no sexo masculino.

We report a case of breast cancer identified in a 72-year-old male as an accidental finding during the course of the investigation of a primary tumor and the search for pulmonary metastases. We address aspects related to the epidemiology, diagnosis, treatment and prognosis of this condition in males.

Cancer de mama oculto: dos casos clínicos analizados según el concepto actual / Occult breast cancer: Report of two cases

Occult breast cancer is expressed as a metastatic axillary lymph node without clinical or imaging evidence of a primary tumor in the breast. The old concept involved non palpable tumors. Its incidence is low, representing only 0.3 to 1 percent of all breast cancer cases. The search for the primary tumors is performed with mammography, whose sensitivity is low, ranging from 0 to 56 percent. Several studies have shown a higher sensitivity of magnetic resonance imaging, ranging from 85 to 100 percent, to detect occult lesions. The treatment of isolated axillary metastases of breast cancer is controversial. An axillary dissection is recommended. If there is a suspicious image, a radiosurgical or stereotaxic biopsy should be done. However, in patients without radiological lesions in the breast, the tendency is not to perform a radical mastectomy as previously recommended, since the primary tumor will not be found in the surgical specimen in two thirds of cases. A superior and external quadrantectomy or exclusive radiotherapy should suffice. An expecting behavior is not recommended as a therapeutic alternative. Treatment should be complemented with hormonal therapy or chemotherapy. The literature suggests that prognosis is better than stage II, with a ten years survival ranging from 50 to 71 percent. We report two patients with a well defined occult breast cancer and based on them, a review of the subject is attempted. Considering its prognosis, physicians should be aware of this uncommon and difficult to diagnose disease.

Chroidal metastasis from breast carcinoma

To report a case of intraocular metastasis from breast carcinoma. A 54-year-old woman diagnosed with multifocal ductal adenocarcinoma, grade III, of the left breast presented with blurred vision of the left eye. Funduscopy under pupil dilation in the left eye revealed a plateau-shaped, yellow choroidal focus measuring 4 optic disc diameters and located 3 optic disc diameters below the fovea. The patient was treated with two cycles of docetaxel and capecitabine. One month later the patient's visual acuity improved. Funduscopy confirmed reduction of oedema. This case shows that impaired vision can be an alarming symptom in a breast cancer patient and a description is given of the morphological features that could help in recognizing the smallest detectable breast cancer metastasis

Metastasis to maxillary gingiva from carcinoma of breast. A case report.

A rare case of metastatic infiltrating duct carcinoma involving gingiva in relation to maxillary left canine-premolar of a 40 year old female is presented. The unilateral gingival enlargement in canine-premolar region was quite unusual. Pertinent history and histological examination revealed that the tumor was a metastatic carcinoma, the primary lesion of which was in the breast. The differential diagnosis of gingival enlargements is discussed in this paper. The resemblance of this mass to an inflammatory hyperplastic condition reflects the need for a detailed case history and examination.

Cáncer de mama sin tumor / Breast cancer without tumor

Existen tres formas bajo las cuales un cáncer de mama puede aparecer clínicamente sin evidencia de un tumor palpable. El cáncer oculto de la mama es aquel que se manifiesta primariamente por metástasis axilares o por metástasis a distancia, sin que el tumor mamario pueda ser evidenciado. El cáncer de mama no palpable es aquel que se manifiesta por síntomas diferentes del tumor, como eczema del pezón o la descarga por el pezón. El cáncer subclínico es aquel que se dianóstica a través de métodos complementarios sin que exista ninguna manifestación clínica previa. La frecuencia con que este tipo de cánceres de mama sin tumor clínico se presentan es desconocida, puesto que varía para cada subtipo y para las diferentes series, según sean experiencias clínicas o proyectos de screening. Dada esta gran variedad de circunstancias, se decidió analizar la experiencia acumulada durante años con el fin de establecer cúal es la forma en que estos cánceres de mama sin tumor se presentan en nuestro medio y cuáles son los resultados de su tratamiento. Se realizó una revisión de las fichas de seguimiento de 37 pacientes atendidas en un período de 15 años (3,8 por ciento del total de cánceres). En 13 de ellas el diagnóstico fue un hallazgo radiológico y en otras 19 habían algún signo de sospecha, entre los cuales la galactorragia fue el más frecuente. En 25 casos el estudio diagnóstico preoperatorio con método cuadriasociado permitió llegar al diagnóstico en el preoperatorio. El 89, 2 por ciento de los cánceres fue de tipo ductal. En 36 casos el tratamiento primario fue quirúrgico, asociado o no a radioterapia. Se encontró un promedio de 1 ganglio axilar comprometido. La sobrevida estimada para el grupo fue 80,02 por ciento a 120 meses

Metástase de carcinoma de mama para a glândula tireóide / Metastasis to the thyroid gland from carcinoma of the breast

Os autores apresentam um caso de metástese para a glândula tireóide produzido por um carcinoma de mama. É discutida a raridade da patologia, assim como os mecanismos de difusäo metastático
