Metástasis cutánea como primera manifestación de un carcinoma papilar capsulado de mama / Cutaneous metastasis as the first manifestation of an encapsulated papillary carcinoma of the breast

Introducción La mama es el órgano interno que con más frecuencia produce metástasis en la piel en las mujeres. Puede ser un signo de enfermedad sistémica avanzada o ser la primera manifestación de un cáncer asintomático. No se han descrito hasta la fecha metástasis cutáneas por carcinomas papilares capsulados de mama. Caso clínico Mujer de 76 años, con elevada comorbilidad y mastectomía radical modificada izquierda 25 años antes por carcinoma ductal infiltrante. Acudió al servicio de Dermatología por una lesión tumoral vascularizada, sangrante y dolorosa de 0,8cm de diámetro localizada en zona retroauricular mastoidea izquierda. Se realizó biopsia escisional de la lesión que, tras estudio anatomopatológico, fue diagnosticada de metástasis cutánea de cáncer de mama. La mamografía derecha y la ultrasonografía demostraron la presencia de un nódulo de 38mm, bien delimitado. La pieza de tumorectomía demostró la presencia de un carcinoma papilar capsulado, antes conocido también como intraquístico. El estudio de extensión resultó negativo para otras metástasis. Conclusión La mama es el origen más frecuente de las metástasis cutáneas de neoplasias internas. Las formas de presentación son variadas y el clínico debe mantener un alto índice de sospecha para poder realizar un diagnóstico adecuado y precoz. (AU)

Introduction The breast is the internal organ that most often produces skin metastasis in women. Metastasis can be a sign of advanced systemic disease or the first manifestation of asymptomatic cancer. To date, there have been no descriptions of cutaneous metastases from papillary carcinomas encapsulated in the breast. Clinical case We report the case of a 76-year-old woman with high comorbidity and a modified radical mastectomy 25 years previously due to infiltrating ductal carcinoma. The patient attended the dermatology department due to a painful, vascularized, bleeding 0.8cm tumor located in the left mastoid retroauricular area. An excisional biopsy of the lesion was performed, which, after pathological study, was diagnosed as cutaneous metastasis from breast cancer. The presence of a well-defined 38mm nodule was confirmed by mammography and ultrasonography. The tumorectomy specimen demonstrated the presence of an encapsulated papillary carcinoma, previously also known as intracystic carcinoma. The extension study was negative for other metastases. Conclusion The breast is the most frequent origin of cutaneous metastases from internal neoplasms. The forms of presentation are varied and clinicians must maintain a high index of suspicion in order to make an accurate and early diagnosis. (AU)

Idiopathic granulomatous mastitis: A systematic review of 3060 patients.

Idiopathic granulomatous mastitis is a rare benign breast disease. A systematic review was designed. Clinical and therapeutic characteristics were analyzed. Human Development Index (HDI) was used to define two groups of study: group A (very high and high HDI) and group B (medium and low HDI). Corticosteroid therapy was done in 69% group A and 78% group B. Surgery was done in 63% in group A and 83% in group B. Antibiotics were used in 68% group A and 88% group B. There is no consensus about optimal treatment for granulomatous mastitis.

Introducción La mastitis granulomatosa es unaenfermedad infrecuente caracterizada por una inflamación granulomatosa crónica de los lobulillos mamarios. Las opciones de tratamiento siguen siendo controvertidas. Objetivo El objetivo del presente estudio fue analizar nuestra experiencia en el diagnóstico y tratamiento de las pacientes con mastitis granulomatosas, valorando la conveniencia de tratamientos quirúrgicos o tratamientos más conservadores. Material y método Se presenta un estudio retrospectivo y descriptivo de las pacientes diagnosticadas y tratadas en nuestro centro desde enero de 2010 hasta diciembre de 2018. Se analizaron las características clínicas y radiológicas de cada una, así como el tratamiento y su evolución. Resultados Los resultados del estudio fueron los siguientes: • El número de pacientes fue 10; el tiempo medio de seguimiento fue de 10,5 meses (rango 2-49 meses); la mediana de edad fue de 44,5 años (rango 31-81 años);ocho pacientes (80%)se manifestaron como tumoración palpable; el tiempo medio de duración de los síntomas fue de 6,8 meses (rango 2-24 meses); el tamaño medio de la lesión alcanzó los 23,6 mm (rango 12-40); una paciente se clasificó como bi-rads 2, 1 paciente como bi-rads 3, 1 paciente como bi-rads 4y 3 pacientes como bi-rads 5. • El tratamiento fue quirúrgico en 6 ocasiones (4 resecciones y 2 drenajes con biopsia) y médico en 4 ocasiones. Siete de las pacientes (70%) se curaron con el tratamiento efectuado (5 con cirugía y 2 con tratamiento conservador). Tres pacientes presentaron recurrencia o persistencia (1 con cirugía y 2 con tratamiento conservador). Conclusiones La mastitis granulomatosa es una enfermedad infrecuente y de causa desconocida, con tendencia a la recurrencia y cronicidad, cuyo tratamiento es todavía motivo de controversia

Introduction Granulomatous mastitis is an infrequent disease characterized by a chronic granulomatous inflammation of mammary lobules. Treatment options remain controversial. Objective The aim of the present study was to analyze our experience in the diagnosis and treatment of patients with granulomatous mastitis, assessing the convenience of surgical treatments or more conservative treatments. Materials and method This is a retrospective and descriptive study of the patients diagnosed and treated in our center from January 2010 to December 2018. We analyzed the clinical and radiological characteristics of each one, as well as the treatment and its evolution. Results • Number of patients 10; mean time of follow-up 10.5 months (range 2-49 months); median of age 44.5 years (range 31-81 years); eight patients (80%) manifested as a palpable tumor;mean duration of symptoms was 6.8 months (range 2-24 months); mean lesion size of 23.6mm (range 12-40); one patient was classified as bi-rads 2, 1 patient as bi-rads 3, 1 patient as bi-rads 4 and 3 patients as bi-rads 5. • The treatment was surgical 6 times (4 resections and 2 drainages with biopsy) and doctor on 4 occasions.

Progastrin represses the alternative activation of human macrophages and modulates their influence on colon cancer epithelial cells.

Macrophage infiltration is a negative prognostic factor for most cancers but gastrointestinal tumors seem to be an exception. The effect of macrophages on cancer progression depends on their phenotype, which may vary between M1 (pro-inflammatory, defensive) to M2 (tolerogenic, pro-tumoral). Gastrointestinal cancers often become an ectopic source of gastrins and macrophages present receptors for these peptides. The aim of the present study is to analyze whether gastrins can affect the pattern of macrophage infiltration in colorectal tumors. We have evaluated the relationship between gastrin expression and the pattern of macrophage infiltration in samples from colorectal cancer and the influence of these peptides on the phenotype of macrophages differentiated from human peripheral monocytes in vitro. The total number of macrophages (CD68+ cells) was similar in tumoral and normal surrounding tissue, but the number of M2 macrophages (CD206+ cells) was significantly higher in the tumor. However, the number of these tumor-associated M2 macrophages correlated negatively with the immunoreactivity for gastrin peptides in tumor epithelial cells. Macrophages differentiated from human peripheral monocytes in the presence of progastrin showed lower levels of M2-markers (CD206, IL10) with normal amounts of M1-markers (CD86, IL12). Progastrin induced similar effects in mature macrophages treated with IL4 to obtain a M2-phenotype or with LPS plus IFNγ to generate M1-macrophages. Macrophages differentiated in the presence of progastrin presented a reduced expression of Wnt ligands and decreased the number and increased cell death of co-cultured colorectal cancer epithelial cells. Our results suggest that progastrin inhibits the acquisition of a M2-phenotype in human macrophages. This effect exerted on tumor associated macrophages may modulate cancer progression and should be taken into account when analyzing the therapeutic value of gastrin immunoneutralization.
