Pathology of breast lesions in female transgender / Patología de las lesiones mamarias en las mujeres transgénero

Female transgender (male to female) is an individual assigned male sex at birth born but who identifies itself and desires to live as female. To achieve and maintain these characteristics, sometimes, it is necessary to undergo hormone therapy and/or surgical treatment. Benign lesions have been described including: fibroadenoma, lobular hyperplasia, pseudoangiomatous stromal hyperplasia, myofibroblastoma, angiolipoma and benign prosthesic reactions. And malignant pathology such as: ductal carcinoma in situ, Paget's disease, infiltrating carcinoma of non-special type (ductal, NOS), secretory adenocarcinoma, malignant phyllodes tumor and breast implant associated anaplastic large cell lymphoma. The described cases of each of these entities are reviewed. In conclusion, hormonal action or prosthesis implantation in female transgender can lead to associated pathologies in the mammary gland that follow a similar pattern to that found in the male breast. Although breast cancer is less frequent than in cisgender women, gynecological control or screening is recommended by some associations

La mujer transgénero (hombre a mujer) es aquella persona nacida varón pero que se identifica y desea vivir como una mujer. Para lograr este objetivo muchas veces precisa de tratamiento hormonal o quirúrgico para alcanzar los atributos sexuales de una mujer. La patología mamaria que estos pacientes pueden presentar es superponible a la patología de la mama masculina, a la patología derivada del tratamiento hormonal y a la relacionada con los implantes mamarios sintéticos. Se han descrito lesiones benignas que incluyen: fibroadenoma, hiperplasia lobulillar, hiperplasia estromal seudoangiomatosa, miofibroblastoma, angiolipoma y reacciones benignas a la prótesis. Y patología maligna como: carcinoma ductal in situ, enfermedad de Paget, carcinoma infiltrante de tipo no especial (ductal, NOS), adenocarcinoma secretor, tumor filoides maligno y linfoma anaplásico de célula grande asociado a prótesis. Se revisan los casos descritos de cada una de estas entidades. En conclusión, la acción hormonal o la implantación de prótesis en las mujeres transgénero pueden llevar asociadas patologías en la glándula mamaria que siguen un patrón similar al de la patología encontrada en la mama del varón. Aunque el cáncer de mama es menos frecuente que en las mujeres cisgénicas, se recomienda un control ginecológico o mediante cribado igual al de estas

Lesiones papilares intraductales mamarias: nuestra experiencia 2007-2017 / Intraductal papillary lesions of the breast: our experience 2007-2017

OBJETIVOS: Revisión y análisis de los casos de lesiones papilares intraductales mamarias diagnosticados en nuestro centro entre enero del 2007 y diciembre del 2017. Estudiar la asociación de las lesiones papilares con el cáncer de mama. PACIENTES Y MÉTODOS: Estudio descriptivo retrospectivo utilizando la base de datos de Anatomía Patológica. Se incluyó a 135 pacientes que en el periodo descrito tuvieron un diagnóstico anatomopatológico de lesión papilar (papiloma benigno aislado, papilomatosis múltiple, papiloma con carcinoma in situ, papiloma con atipia o carcinoma papilar intraductal). Las variables principales a analizar fueron la edad de las pacientes, las pruebas diagnósticas realizadas, la presencia de lesiones de mayor grado asociadas a la lesión papilar y el desarrollo de neoplasia de mama durante el seguimiento. RESULTADOS: La edad media de las pacientes fue de 50 años. La ductoscopia demostró ser una prueba con alta sensibilidad diagnóstica (88%). En 12 casos (9%) existía carcinoma en la lesión papilar o en sus alrededores (8 carcinomas in situ y 4 infiltrantes) y en 4 casos (3%) encontramos hiperplasia atípica asociada. Con un seguimiento medio de 34 meses, 6 pacientes tuvieron una recidiva en forma de lesión papilar (una papilomatosis múltiple y 5 papilomas), 3 pacientes recidivaron en forma de lesión neoplásica y una paciente desarrolló una neoplasia contralateral. CONCLUSIONES: Ante la sospecha de una lesión papilar y la presencia de secreción por el pezón, debemos considerar la realización de una ductoscopia por su alta sensibilidad. La alta incidencia de una neoplasia asociada a la lesión papilar o su aparición durante el seguimiento justifica su exéresis quirúrgica completa y un seguimiento estricto

OBJECTIVES: To provide a review and analysis of cases of intraductal papillary breast lesions diagnosed at our centre between January 2007 and December 2017, and to study the association between papillary lesions and breast cancer. PATIENTS AND METHODS: We performed a retrospective descriptive study using the pathology database of our centre. We included 135 patients with a pathological diagnosis of papillary lesion (isolated benign papilloma, multiple papillomatosis, papilloma with carcinoma in situ, papilloma with atypia or intraductal papillary carcinoma). The main variables were age, the diagnostic procedures performed, the presence of higher-grade lesions associated with the papillary lesion, and the development of breast neoplasms during follow-up. RESULTS: The patients' mean age was 50 years. Ductoscopy had high sensitivity (88%). Twelve patients (9%) had carcinomas on the papillary lesion or its surrounding areas (8 carcinomas in situ and 4infiltrating carcinomas) and 4 patients (3%) had associated atypical hyperplasia. With a mean follow-up of 34 months, 6 patients had recurrence as a papillary lesion (one multiple papillomatosis and 5papillomas), 3 patients relapsed with a neoplastic lesion, and one patient developed a contralateral neoplasm. CONCLUSIONS: In the presence of a suspected papillary lesion and nipple secretion, ductoscopy should be considered due to its high sensitivity. The high incidence of neoplasms associated with papillary lesions or their development during follow-up justifies their complete surgical excision and strict follow-up

Carcinoma escamoso con cambios quísticos asociado a embarazo / Pregnancy-associated squamous cell carcinoma with cystic changes

El cáncer de mama asociado al embarazo representa una compleja situación clínica por la dificultad de su diagnóstico. La clínica principal del cáncer de mama gestacional es el nódulo palpable, sin embargo, debido a los cambios fisiológicos que se producen en la glándula durante el embarazo o la lactancia, el diagnóstico es especialmente difícil, lo que provoca un retraso en el diagnóstico. El carcinoma escamoso es un subtipo histológico raro, que representa menos del 0,5% de los cánceres de mama. Se trata de un tipo de tumor que suele presentarse en forma de masa quística y cuyo diagnóstico puede confundirse con una entidad benigna. Se presenta el caso de una mujer de 35 años diagnosticada de un carcinoma escamoso de mama tras múltiples ingresos médicos por sospecha de galactoceles y mastitis. El cáncer de mama debe ser el primer diagnóstico diferencial que tener en cuenta ante un nódulo persistente que no mejora tras tratamiento médico y es importante pensar en el carcinoma escamoso en caso de que se trate de una masa quística o absceso mamario

Pregnancy-associated breast cancer represents a complex clinical situation due to the difficulty of diagnosis. The main clinical feature is a palpable nodule. However, due to the physiological changes that occur in the gland during pregnancy or lactation, diagnosis is especially difficult and sometimes delayed. Squamous cell carcinoma is a rare histological subtype, representing less than 0.5% of breast cancers. It usually presents as a cystic mass that can be mistaken for a benign entity. We present the case of a 35-year-old woman diagnosed with squamous cell carcinoma of the breast after multiple medical admissions due to suspicion of galactoceles and mastitis. Breast cancer should be the first differential diagnosis to consider in the presence of a persistent nodule that does not improve after medical treatment and it is important consider squamous cell carcinoma if there is a cystic mass or breast abscess

Influence of the in situ component in 389 infiltrating ductal breast carcinomas.

BACKGROUND: Our aim was to evaluate and compare lymph node involvement, as well as disease-free survival (DFS) and overall survival (OS), between infiltrating ductal carcinoma with (group 1) and without (group 2) intraductal carcinoma component in order to determine the prognostic value of the intraductal component. METHODS: Data from 389 cases of infiltrating ductal carcinoma of the breast were included in the study by means of reviewing medical charts and pathology slides. RESULTS: There was no statistically significant difference between both groups regarding node status. The 5-year DFS rate was 90.7% in group 1 and 81.8% in group 2 (p = 0.014), with a median follow-up of 73.2 months (95% CI 68.3-77.4). There was no statistically significant difference in 5-year OS between groups (98% group 1 vs. 93% group 2) with a median global survival of 134 months (95% CI 131-137). CONCLUSIONS: The presence of intraductal component in the infiltrating carcinoma seems to increase DFS and may be an independent and favorable prognostic factor for breast cancer.

[Node status in 454 ductal breast cancers cases according to the association with in situ component]. / Afectación ganglionar en 454 casos con carcinoma ductal infiltrante de mama según el hallazgo de componente intraductal asociado.

BACKGROUND: Studies have shown that breast infiltrating ductal carcinoma develops from precursor lesions or pre-invasive. It is accepted that the risk of invasive ductal carcinoma increased slightly in hyperplasia, but especially in cases of atypical hyperplasia and intraductal carcinoma. OBJECTIVES: To evaluate and compare the nodal status between ductal breast cancer with in situ component (group 1) or without it (group 2). MATERIAL AND METHOD: Descriptive and retrospective study that included 454 ductal breast cancers. Data concerning clinical and pathological variables was collected. All data was compared between both groups. RESULTS: Among all cases, 176 (38.8%) showed positive lymph nodes, 136 patients (39.5%) from group 1 and 40 cases (36.4%) from group 2. Among group 1 cases, high-grade subgroup showed higher positive lymph node rate (82 cases, 55.4%) than the extensive in situ carcinomas subgroup (84 cases, 49.7%). Both of them had a significant higher rate than group 2 cases (p = 0.003 y p = 0.028, respectively). Moreover, the low-grade in situ carcinomas without cellular necrosi had positive lymph nodes just in 30 cases (24%), significantly lower (p = 0.034) than group 2. CONCLUSIONS: We did not find overall statistical differences between groups depending on in situ associated component. But when we analyzed in situ subgroups, we found differences with higher positive lymph node rate in high grade carcinomas and extensive in situ carcinomas subgroups, while lower affectation rates were observed in low grade carcinomas (without cellular necrosis), compared to the group of breast cancers without in situ component associated.

Rotura uterina. Diagnóstico y consecuencias en una gestante de 30 semanas / Uterine rupture. Diagnosis and repercussions at 30 weeks of pregnancy

La rotura uterina es una complicación obstétrica infrecuente con una morbimortalidad maternofetal alta. Su diagnóstico temprano y tratamiento inmediato son importantes factores pronósticos, tanto para la madre como para el feto. Presentamos el caso de una paciente gestante de 30 semanas que presentó una rotura uterina espontánea en la zona de una cicatriz de miomectomía laparoscópica anterior, lo que dio lugar a un hemoperitoneo materno y a la muerte fetal intraútero. Se practicó un tratamiento quirúrgico de urgencia mediante una histerectomía subtotal por vía abdominal (AU)

Uterine rupture is an infrequent obstetric complication with high morbidity and mortality for both the mother and fetus. Early diagnosis and treatment of this entity are important prognostic factors. We report the case of woman at 30 weeks of pregnancy with spontaneous uterine rupture in a previous scar from a laparoscopic myomectomy, giving rise to maternal hemoperitoneum and intrauterine fetal death. Emergency surgery was performed with subtotal abdominal hysterectomy (AU)
