ABSTRACT

Resumen Introducción: El tumor Phyllodes mamario es una entidad muy poco frecuente, con tendencia a la recidiva local y una tasa de malignización de 5-10%. La base de su tratamiento es la resección quirúrgica. Material y Métodos: Mujer de 32 años diagnosticada de un tumor Phyllodes maligno en mama derecha sometida en otro centro a cirugía conservadora con colocación de expansor y a dos tumorectomías posteriores por recidiva local. Fue referida a nuestro Hospital al presentar una nueva recidiva de gran tamaño (9,2 cm) para valoración de intervención quirúrgica. Resultados: Se realizó exéresis del tumor (remanente de tejido mamario y músculo pectoral mayor) y retirada del expansor con reconstrucción mamaria con colgajo de dorsal ancho en el mismo tiempo quirúrgico. En el momento actual la paciente se encuentra pendiente de iniciar tratamiento radioterápico. Conclusiones: El tumor Phyllodes maligno es una entidad poco frecuente y cuyo manejo terapéutico se basa en la resección quirúrgica con márgenes. De forma adyuvante se puede administrar quimiorradioterapia. Es de gran importancia realizar un manejo multidisciplinar e individualizado de cada caso para ofrecer el mejor pronóstico.


Introduction: Phyllodes tumor is a rare entity, with a high tendency to local recurrence and a malignancy rate of 5-10%. The basis of its treatment is the surgical resection. Materials and Method: We report a 32-year-old woman who was diagnosed of a malignant Phyllodes tumor who had previously underwent conservative breast surgery and expander placement in another center. Two subsequent lumpectomies due to local recurrences were necessary. She was referred to our Hospital for she presented a new large-sized recurrence (9.2 cm) at the retroarelor area for assessment of new surgical treatment. Results: Surgical resection of the tumor (remnant of mammary tissue and pectoralis major muscle) and removal of the expander with immediate breast reconstruction with latissimus dorsi flap was performed. At the present time, the patient is pending radiotherapeutic treatment. Conclusions: Malignant Phyllodes tumor is a rare entity whose therapeutic management is based on margin-free surgical excision. Adjuvant chemoradiotherapy might be administered. It is very important to carry out a multidisciplinary and individualized management of each case to offer the best possible forecast.

ABSTRACT

Los tumores Phylloides se originan del estroma de la glándula mamaria. La frecuencia es menor a 1 por ciento predominando en mujeres entre 35 a 55 años. Típicamente se presentan como nódulos móviles, redondeados, usualmente indoloros, y pueden tener crecimiento rápido. El tratamiento de elección es la escisión local de la lesión, tanto para formas benignas y malignas, con márgenes de al menos 1 cm. Presentar el caso de una paciente con Tumor Phylloides de mama y su evolución natural por retraso en el diagnóstico y tratamiento temprano. Paciente de sexo femenino, 42 años, nulípara, sin antecedentes familiares de Cáncer de mama que consulta presentando un tumor de gran tamaño, en cuadrante inferior interno de la mama izquierda, cuyo crecimiento fue progresivo hasta deformar la glándula mamaria. Se le realizó biopsia por Trucut, con diagnostico histopatológico de tumor Phylloides de bajo grado de malignidad y se somete a tratamiento radical mediante mastectomía de limpieza. Resultados: Se realizó mastectomía de limpieza, sin complicaciones postquirúrgicas, siendo la evolución clínica satisfactoria. Toda paciente con tumor de crecimiento progresivo después de los 30 años, debe de ser de estudiada de inmediato para determinar su estirpe histológica y el tratamiento adecuado, sin permitir que continúe con la evolución de la historia natural de enfermedad(AU)


Phylloides tumors originate from the stroma of the mammary gland. The frequency is less than 1percent predominantly in women aging 35 and 55 years. They typically present as mobile, rounded nodules, usually painless, and may grow rapidly. The treatment of choice is local excision of the lesion, both for benign and malignant forms, with margins of at least 1 cm. We present the case of Phylloides tumor of the breast and its natural evolution due to delay in diagnosis and early treatment with a 42-year-old female patient. She was nulliparous, with no family history of breast cancer who came to consultation presenting a large tumor in the inner lower quadrant of her left breast. The tumor grew progressively until the mammary gland was deformed. A trucut biopsy was performed with a histopathological diagnosis of Phylloides tumor of low grade of malignancy. This patient underwent radical treatment by mastectomy. Cleaning mastectomy was performed, without postoperative complications, and the clinical evolution was satisfactory. All patients with progressive growth after the age of 30 should be studied immediately to determine histological characteristics of the tumor, and the appropriate treatment to prevent the evolution of the natural history of the disease(AU)

ABSTRACT

Las lesiones mamarias se dividen histológicamente en dos grandes grupos, malignas y benignas. Las lesiones malignas pueden ser de origen ductal o lobulillar, siendo el carcinoma ductal infiltrante la neoplasia invasiva más frecuente. Las lesiones benignas se clasifican en no proliferativas, proliferativas sin atipias y proliferativas con atipias. Dentro de los dos últimos grupos se encuentran entidades que conllevan un alto riesgo de desarrollar carcinoma de mama, como pueden ser la hiperplasia ductal atípica, la cicatriz radial o la neoplasia lobular. Revisamos en qué consisten dichas entidades y cuáles son sus características principales en imagen, fundamentalmente en mamografía y ecografía. Si tras realizar una biopsia se obtiene uno de esos diagnósticos histológicos, es importante analizar las características imagenológicas y el tipo de procedimiento realizado (número de cilindros obtenidos, calibre de aguja...), para realizar un adecuado manejo posterior. En algunos casos la actitud a seguir será la extirpación quirúrgica completa de la lesión, mientras que en otros se podrá realizar una extirpación percutánea (mediante biopsia con aguja de vacio), o incluso seguimiento estricto por imagen. Mediante diferentes casos mostraremos nuestra experiencia y analizaremos la literatura vigente para recordar esas entidades y llegar a un consenso adecuado sobre el manejo de las mismas.


Breast lesions are divided histologically into two large groups, malignant and benign. Malignant lesions may be of ductal or lobular origin, with infiltrating ductal carcinoma being the most frequent invasive neoplasm. Benign breast lesions are classified as proliferative, proliferative without atypia and proliferative with atypia. Within the last two classifications are entities that carry a high risk of developing breast carcinoma, such as atypical ductal hyperplasia, radial scar or lobular neoplasia. We review what these entities consist of and what are their fundamental characteristics in image, fundamentally in mammography and ultrasound. When we perform one of these histological diagnoses after a biopsy, it is important to analyze the radiological characteristics and the type of procedure performed (number of cylinders, needle gauge ...) to perform an appropriate posterior management. In some cases the attitude to be followed will be the complete surgical removal of the lesion, while in others a percutaneous excision (through vacuum needle biopsy) or even strict image follow-up may be performed. Through different cases we will show our experience and analyze current literature to remember these entities and reach an adequate management consensus.

ABSTRACT

Phyllodes tumour is an uncommon fibro epithelial tumour of breast that often presents clinically as a rapidly enlarging lump. On mammography it appears as a soft tissue density well circumscribed mass. Ultrasound shows it to be a solid hypoechoic mass with small cystic spaces. A case of malignant phyllodes tumour with an atypical appearance of intracystic tumour on sonography is reported with pertinent imaging features and histopathological diagnostic criteria. The tumour had undergone osteosarcomatous differentiation
