Mastopatía diabética. Revisión sistemática con 93 pacientes / Diabetic mastopathy. A systematic review of 93 patients

Introducción La mastopatía diabética (MD) es una afectación benigna de la mama que aparece en pacientes diabéticas con mal control glucémico de larga evolución. La enfermedad se caracteriza por la aparición de nódulos fibrosos que pueden simular tanto clínica como radiológicamente un cáncer de mama. Su diagnóstico debe realizarse con biopsia con aguja gruesa (BAG) y el tratamiento debe evitar resecciones quirúrgicas. El objetivo de este trabajo es caracterizar con más exactitud esta enfermedad y sus características aportando claridad en su diagnóstico diferencial. Material y métodos Se ha realizado una revisión sistemática de los artículos publicados en los últimos 5 años en las principales bases de datos médicas usando para ello los términos «Mastopatía diabética» y «Diabetic mastopathy». Se incluyeron todo tipo de artículos científicos que aportasen datos sobre la MD, excluyendo aquellos que incluyeran otras enfermedades inflamatorias de la mama. Se seleccionaron finalmente 28 artículos. Para el análisis estadístico se dividió a las pacientes en 2 grupos, diabetes mellitus (DM) tipo 1 (DM1) y DM tipo 2 (DM2), y se compararon la media y la proporción de las diferentes variables analizadas utilizando para ello la prueba t de Student. Se utilizó el programa STATA para realizar el análisis estadístico. Resultados Se analizaron 28 artículos, con un total de 93 pacientes incluidas. En los artículos analizados todos los pacientes eran mujeres. La mayoría de las pacientes presentaron DM1 y el tiempo medio de evolución de la diabetes fue de 20 años. La lesión asociada a la DM que se observó con mayor frecuencia fue la retinopatía diabética (34%). La lesión palpable fue la forma de manifestación más frecuente (53%). Respecto al diagnóstico el hallazgo mamográfico más habitual, fue la hiperdensidad asimétrica y en la ecografía la lesión hipoecoica de bordes irregulares y sombra acústica posterior. El tratamiento más habitual fue conservador. Conclusión ... (AU)

Introduction Diabetic mastopathy is a benign disease of the breast that develops in patients with long-standing diabetes and poor glycemic control. The disease is characterised by fibrous nodules that can be confused with breast cancer both clinically and radiologically. Diagnosis should be made with core needle biopsy (CNB) and treatment should avoid surgical resections. The main objective of this study was to characterise this rare disease in order to improve its differential diagnosis and treatment. Material and methods A systematic review was conducted, including articles published in the last 5 years in the main medical databases using the terms “Mastopatía diabética” and “Diabetic mastopathy”. We included all types of scientific articles providing data on diabetic mastopathy. We excluded articles including other inflammatory breast diseases. Finally 28 articles were selected. For the statistical analysis, patients were divided in 2groups: DM1 patients and DM2 patients. The mean and proportion of the different variables were analysed with the Student t-test. The statistical analysis was performed with the STATA programme. Results We analysed 28 articles, with 93 patients. None of the included articles reported male patients. Most patients had type 1 diabetes and diabetic mastopathy developed at a mean of 20 years after diabetes onset. The most frequent complication of diabetes was diabetic retinopathy (34%). The most common manifestation was a palpable nodule (53%). Regarding diagnosis, the most common mammographic finding was asymmetric hyperdensity and the most common ultrasound finding was a hypoechoic lesion with irregular edges and posterior acoustic shadow. The most frequent treatment was conservative. Conclusion... (AU)

Imágenes en mastopatia diabética / Mr imaging of diabetic mastopathy

Objective: To retrospectively analyze the clinical records and imaging data of patients with diabetic mastopathy according to pathological findings of samples obtained by histological puncture with ultrasound guidance. Methods: Between 2002 and 2007, six patients were diagnosed with diabetic mastopathy, and their medical records and MR images were assessed. All patients underwent both mammography and ultrasound examination. One of them was additionally submitted to MRI. Results: The patients' mean age was 36.6 years. Mammograms showed asymmetric tissue densifications without micro calcifications, while ultrasound examination evidenced ill-defined solid nodular or pseudonodular areas greater than 2 cm, with posterior sonic attenuation. Magnetic resonance imaging revealed a nodular area with poorly defined contours with enhancement similar to normal breast tissue. By performing eco-guided biopsy, it was possible to establish the differential histological diagnosis of breast carcinoma and to confirm diabetic mastopathy. Conclusion: Diabetic mastopathy presents mammographic and ultrasound imaging features indistinguishable from breast cancer. Since MRI does not reveal pathological stromal enhancement it can be helpful for a differential diagnosis. The echo-guided biopsy allows the diagnosis of this condition.

Objetivo: Analizar retrospectivamente las historias clínicas e imágenes de pacientes conmastopatía diabética, según hallazgos en anatomía patológica de muestras obtenidas por punción histológica con guía ecográfica. Material y Métodos: Entre los años 2002 y 2007, se diagnosticaron 6 pacientes con mastopatía diabética, evaluándose sus historias clínicas e imágenes. A todas las pacientes se le efectuó mamografía y ecografía; a una paciente se realizó además resonancia magnética. Resultados: La edad promedio de las pacientes fue de 36,6 años. Las mamografías mostraron densificaciones tisulares asimétricas sin microcalcificaciones; las ecografías evidenciaron áreas sólidas nodulares o seudonodulares mal definidas, mayores a 2 cm, con atenuación sónica posterior y la resonancia magnética: un área nodular de contornos mal delimitados con realce similar al tejido mamario normal. La punción biopsia ecoguiada pudo establecer el diagnóstico histológico diferencial con carcinoma mamario y confirmar mastopatía diabética. Conclusión: La mastopatía diabética presenta características imaginológicas en mamografía y ecografía que pueden ser similares al carcinoma. La resonancia magnética, al no presentar realce patológico estromal, puede colaborar en el diagnostico diferencial. La biopsia eco-guiada permite el diagnóstico de esta patología.

Mastopatia diabética: um inusitado diagnóstico diferencial: relato de caso / Diabetic mastopathy: an unusual differential diagnosis: a case report

A mastopatia diabética acomete mulheres na pré-menopausa com diabetes mellitus tipo 1 de longa data. Seu diagnóstico é feito associando achados clínicos (espessamento ou nódulo mamário endurecidos, uni ou bilateral), radiológicos (aumento da densidade mamária), ultra-sonográficos (acentuada sombra acústica posterior) e histopatológicos (fibrose e infiltrado linfocítico perivascular e periductal). Pode simular carcinoma. Neste artigo relata-se um caso de paciente com mastopatia diabética.

Diabetic mastopathy affects premenopausal women with longstanding type 1 diabetes mellitus. The diagnosis is based on clinical findings (uni or bilateral hardened, palpable mass) associated with radiological (increase in breast density), sonographic (marked posterior acoustic shadowing), and histopathological (fibrosis and perivascular and periductal lymphocytic infiltration) findings. This disease may clinically simulate a breast carcinoma. The case of a patient with diabetic mastopathy is reported.

Mastopatía diabética: presentación de caso / Diabetic masthopathy: case presentation

La mastopatía diabética es una entidad poco frecuente y de relativa nueva definición que puede simular una neoplasia maligna. Se presenta principalmente en pacientes diabéticas premenopáusicas insulino-dependientes con antecedentes de hiperglucemias prolongadas. Su etiopatogenia se asocia con el depósito estromal de colágeno y una infiltración linfocitaria de células B de causa autoinmune. La presentación clínica y radiológica no permiten concluir con un diagnóstico certero, siendo necesario la realización de biopsia con aguja gruesa y en la mayoría de los casos biopsia incisional. Presentamos el manejo de un caso en nuestra unidad.

Diabetic masthead is uncommon breast lesion and relative new definition that can be mistaken by a malignant neoplasia. It is mostly described in premenopausal patient’s diabetic and insulin dependent with history of persistent hyperglycemia. The ethiopatogenic is associated with extensive lymphocytic infiltration mostly B cells is detected an autoimmune reaction. Neither clinical nor radiologic exams rule out malignancy, so core biopsy and even incision biopsy are mandatory: Ephiteloid fibroblast in dense fibrous stroma is unique to the condition in diabetics. We present a case report, diagnosed and treated in our center.

Regression of the fibrous disease of the breast in a non-diabetic woman after pregnancy and breastfeeding

Fibrous mastopathy, also known as diabetic mastopathy and lymphocytic mastopathy, may mimic breast cancer at the physical examination, mammography, and ultrasound. We report a case of a woman who presented a non-tender mass clinically suggestive of breast carcinoma; however, the fine-needle aspiration cytology indicated atypia and the core needle biopsy revealed lymphocytic mastopathy. The magnetic resonance imaging of the breast showed a lesion with benign features. It was not demonstrated diabetics mellitus and autoimmune diseases. The patient got pregnant, breastfed, and it was observed the progressive regression of the lesion, with complete disappearance of the solid mass. Three years and three months later, there was no palpable mass at the clinical examination and ultrasound. In conclusion, fibrous mastopathy shall be considered for all breast lesions, regardless of the diagnosis of diabetes mellitus. Once a definitive diagnosis of this pathology is reached, it is recommended clinical, imaging studies and fine-needle aspiration biopsy follow-up of the patient, avoiding unnecessary surgical procedures.

A mastopatia fibrótica, também conhecida como mastopatia diabética e mastopatia linfocítica, pode, ao exame clínico, mamografia e ultra-som, simular um carcinoma mamário. Descrevemos o relato de uma mulher na qual o nódulo foi inicialmente suspeito de carcinoma mamário, mas o diagnóstico pela punção aspirativa com agulha fina foi de atipia, e o com biópsia com agulha grossa foi de mastopatia linfocítica. A ressonância magnética da mama mostrou a lesão com características de benignidade. Não foram demonstradas diabetes mellitus e doenças auto-imunes. A paciente engravidou, amamentou e foi observada regressão progressiva da lesão, com desaparecimento da mesma. A paciente persiste sem lesão na mama ao exame clínico e de ultra-som após acompanhamento de três anos e três meses. Em conclusão, a mastopatia fibrótica deve ser considerada para todas as lesões de mama, mesmo em pacientes sem diabetes mellitus. Quando o diagnóstico definitivo da patologia for realizado, é recomendável o acompanhamento da paciente com estudos clínicos e de imagem e biópsia com agulha fina, evitando-se procedimentos cirúrgicos desnecessários.

Mastopatia diabética bilateral- relato de caso / Bilateral diabetic mastopathy - case report

Objetivo: relatar um caso de mastopatia diabética bilateral, um tipo incomum e raro de doença inflamatória da mama. A associação entre mastopatia e diabete insulino-dependente é uma condição não muita conhecida. Relato do caso: paciente do sexo feminino, trinta e dois anos de idade, com diagnóstico de diabete desde os doze anos. A investigação clínica se baseou na anamnese e exame físico; realizada, também, ultra-sonografia e histopatologia. Considerações finais: o caso apresentado demonstra a importância do diagnóstico precoce das doenças que afetam a mama e a gravidade da mastopatia diabética, quando detectada tardiamente.
