Are both distinct epithelial and stromal cells molecular analysis from phyllodes tumors versus fibroadenoma components affected in breast fibroepithelial progression?

Purpose: To determine molecular events involved in the tumorigenesis of phyllodes tumors (PT) and the role of each stromal (SC) and epithelial (EC) cell. Methods: Frozen breast samples enriched with epithelial and stromal cells from three fibroadenomas and 14 PT were retrieved and laser microdissected. Sanger and polymerase chain reaction-based sequencing of exon 2 MED12 and TERT promoter hotspot mutations were performed; 44K microarray platform was used to analyze gene expression. Results: All three fibroadenomas (FAs) presented mutations in MED12, but not in TERT, whose mutation was observed in five of the 14 PTs. EC and SC of each affected tumor displayed identical alterations. Of the total differentially expressed genes (DEG) (EC = 1,543 and SC = 850), 984 were EC-eDEGs and 291 were SC-eDEGs. We found a high similarity of diseases and functions enriched by both cell types, but dissimilarity in the number of enriched canonical pathways. Three signaling canonical pathways overlapping with EC and SC were predicted to be activated in one cell type and inactivated in the other, while no overlap in eDEGs was assigned to them. We also identified 13 EC-eDEGs and five SC-eDEGs enriched networks, in which the SC-eDEGs were able to segregate FA from PT samples. Conclusions: Identical TERT mutations from both SC and ES origins might affect the PTs tumorigenesis. Gene expression differences suggest coordinated molecular processes between these components with determinant differences acquired by SC, able to fully distinguish PTs from FAs lesions.

Expression of metalloproteinases 2 and 9 and plasma zinc concentrations in women with fibroadenoma

SUMMARY OBJECTIVE: This study aims to investigate the association between the immunohistochemical expression of matrix metalloproteinase-2 and matrix metalloproteinase-9 and plasma zinc in women with fibroadenoma. METHODS: This cross-sectional study included 37 premenopausal women with fibroadenoma. Waist circumference and body mass index of the participants were measured. Plasma zinc concentrations were determined using atomic flame absorption spectrophotometry. Fragments of breast tissue were fixed and incubated with primary mouse monoclonal antibodies (monoclonal antibodies matrix metalloproteinase -2 -507 and monoclonal antibodies matrix metalloproteinase -9-439). Semi-quantitative analysis of matrix metalloproteinase-2 and matrix metalloproteinase-9 immunoreactivity was performed. Spearman's test and Friedman's test were used for statistical analyses. The p<0.05 were considered statistically significant. RESULTS: The average age of the participants was 32.81±9.51 years. The body mass index and waist circumference values were within the normal range. The mean plasma zinc concentration was 42.73±13.84 µg/dL, with 94.6% inadequacy. A statistically significant difference was found between the positive expression of matrix metalloproteinase-2 and matrix metalloproteinase-9 (p=0.0184). There was no significant correlation between the matrix metalloproteinase expression and the plasma zinc levels. CONCLUSIONS: Women with fibroadenoma had hypozincemia and positive expression of metalloproteinases.

Carcinoma ductal in situ associado à fibroadenoma: relato de caso / Carcinoma ductal in situ arising in a fibroadenoma: report of a rare case

Apesar de fibroadenoma ser uma das lesões mais comuns da mama, sua correlação a alteração maligna é rara.1,2,3,5,7 Quando ocorre tem apresentação clínica similar a dos fibroadenomas típicos, diagnóstico anatomopatológico em geral pós-cirúrgico e tratamento conforme do carcinoma do mesmo tipo histológico isolado.1,2,3,4,6 Apresentamos caso de mulher de 52 anos, apresentando em propedêutica investigativa nódulo em mama direita. Core-biopsy sugeriu carcinoma ductal in situ desenvolvido dentro de fibroadenoma, confirmado em análise anatomopatológica pósoperatória. Tratamento e seguimento se deu conforme já estabelecido pela literatura para carcinoma in situ. Devido baixa incidência, há poucas evidências científicas quanto ao diagnóstico, tratamento e prognóstico desse tipo de lesão. Portanto, apresentar à comunidade científica casos de carcinoma inclusos a fibroadenoma se faz relevante.

Although fibroadenoma is one of the most common lesions of the breast, its correlation with malignant changes is rare. When it occurs, the clinical presentation is similar to typical fibroadenomas, anatomopathological diagnosis is after surgery and treatment goes according to the carcinoma histological type. A case of a 52-year-old woman is presented, with an impalpable nodule in the right breast, diagnosed from screening exams. Corebiopsy suggested carcinoma ductal in situ developed within fibroadenoma, confirmed in the postoperative anatomopathological analysis. Treatment and follow-up followed as established in the literature for carcinoma in situ. Due the low incidence, there are poor scientific evidence regarding the diagnosis, treatment and prognosis of this type of injury. Therefore, presenting cases of Carcinoma ductal in situ arising in a fibroadenoma to the scientific community is so relevant.

Fibroadenoma gigante juvenil de mama: presentación de un caso clínico / Juvenile giant fibroadenoma of the breast: presentation of a clinical case

RESUMEN El fibroadenoma gigante juvenil es un tumor de mama benigno y una variante rara de los fibroadenomas. La presentación clínica suele ser una masa tumoral unilateral, de crecimiento rápido e indolora. En este artículo presentamos el caso de un fibroadenoma gigante juvenil de 12 cm de diámetro en la mama de una niña de 13 años. Se realiza estudio radiológico e histológico de la lesión siendo categorizada como un fibroadenoma gigante juvenil por lo que se realiza tumorectomía completa con remodelación mamaria posterior. A los dos meses de seguimiento, la paciente se encuentra sin signos de recidiva, con buena situación general y a la espera de cirugía de remodelación mamaria.

ABSTRACT Juvenile giant fibroadenoma is a benign breast tumor and a rare variant of fibroadenomas. The clinical presentation is usually a painless, fast growing, unilateral tumor mass. In this article we present the case of a giant juvenile fibroadenoma of 12 cm in diameter in the breast of a 13-year-old girl. A radiological and histological study of the lesion was carried out and it was categorized as a juvenile giant fibroadenoma, so a complete lumpectomy with posterior breast remodeling was performed. After two months of follow-up, the patient is without signs of recurrence, in good general condition and waiting for the breast remodeling surgery.

Fibroadenoma como causa de tumor en la vulva. Presentación de caso / Fibroadenoma as the cause of tumor in the vulva. A case report

Introducción: El fibroadenoma es una lesión bastante común en mama, pero su localización en la región vulvar es extremadamente rara, con alrededor de sesenta casos, descritos en la literatura. Se presenta como una masa unilateral, subcutánea y asintomática, de crecimiento insidioso. El tamaño de este tipo de lesión varía entre 1 y 12 cm en los casos reportados hasta la fecha. A pesar de ser infrecuentes, las tumoraciones a nivel vulvar continúan siendo importante motivo de consulta. La histogénesis de este tipo de lesiones ha sido tema de discusión en los últimos años, sobresalen dos teorías: la presencia de tejido mamario ectópico, y la degeneración tumoral de un grupo de glándulas similares a tejido mamario, descritas como componente habitual de la región. Objetivo: Aportar un diagnóstico diferencial polémico de tumores vulvares. Presentación del caso: Se presenta una paciente de 22 años con diagnóstico histopatológico de fibroadenoma de vulva. Se realiza exéresis de la lesión, la cual al examen macroscópico midió aproximadamente 15 cm en su eje longitudinal (la más grande reportada en la literatura). Conclusiones: A pesar de su baja frecuencia de presentación, el fibroadenoma de vulva es una entidad a tener en cuenta como diagnóstico diferencial de los tumores subcutáneos de localización vulvar(AU)

Introduction: Fibroadenoma is a fairly common lesion in the breast tissue, but its location in the vulvar region is extremely rare, with about 60 specific cases in the literature. It is presented as a unilateral, subcutaneous and asymptomatic mass, with insidious growth. The size of this type of lesion is between 1 and 12 cm in the cases reported to date. Despite being infrequent, vulvar tumors continue to be important reasons for medical consultation. The histogenesis of this type of lesions has been the subject of discussion in recent years; two theories stand out: the presence of ectopic breast tissue, and tumor degeneration of a group of glands similar to breast tissue described as a common component of the region. Objective: To providea polemic differencial diagnosis of vulvar tumors. Case presentation: We present a 22-year-old patient with histopathological diagnosis of vulvar fibroadenoma. Excision of the lesion was performed, which at the macroscopic examination measured approximately 15 cm in its longitudinal axis (the largest reported in the literature). Conclusions: Despite its low frequency of presentation, vulvar fibroadenoma needs to be considered as differencial diagnosis of vulvar tumors(AU)

Adenomioepitelioma de mama. Presentación de un caso / Adenomyoepithelioma of the breast. A case presentation

RESUMEN El adenomioepitelioma es un tumor de la mama poco frecuente, generalmente de comportamiento benigno, de histología variable, que puede simular otras lesiones epiteliales, mioepiteliales y bifásicas de la mama. Patológicamente es un desorden raro caracterizado por la proliferación simultánea de las células del epitelio ductal y células mioepiteliales. Es más común en las glándulas salivales o en la piel, raras veces es encontrado en el tejido mamario. Afecta fundamentalmente al sexo femenino, alrededor de los 50 años de edad. Clínicamente se presenta por una pequeña masa palpable que ocupa cuadrantes centrales de la mama. El tratamiento de elección es la exéresis amplia de la lesión. Es frecuente la recidiva local y en algunas ocasiones puede tener degeneración maligna. Se presentó una paciente 13 años de edad, que acudió al Servicio de Cirugía del Hospital "Dr. Mario Muñoz Monroy" , municipio Colón, provincia de Matanzas con un tumor de consistencia dura; pero no pétreo, de 8-10 cm de diámetro, en cuadrantes inferiores y región retroareolar de la mama derecha. El estudio sonográfico informó la presencia de una imagen hipoecoica, de forma oval. Se realizó exéresis de la lesión. El estudio patológico e inmunohistoquímico aportó un adenomioepitelioma de la mama. La paciente no presentó complicaciones postoperatorias. Actualmente se sigue por consulta a 7 años de la cirugía.

ABSTRACT Adenomyoepithelioma is a very rare and generally benign tumor of varying histology that can simulate other epithelial, myoepithelial and biphasic lesions of the breast. Pathologically it is rare disorder characterized by the simultaneous proliferation of ductal epithelium and myoepithelial cells. It is more common in salivary glands and in skin. Rarely found in mammal tissue, it mainly affects women, aged around 50 years, and clinically presents like a palpable mass occupying central breast quadrants. The treatment of choice is the extensive excision of the lesion. Local recidivisms is very frequent, and sometimes they could have malignant degeneration. The authors present the case of a female patient, aged 13 years, who assisted the service of Surgery of the Hospital "Dr. Mario Muñoz Monroy", municipality of Colon, province of Matanzas with a tumor of hard consistence, of 8-10 cm diameter, in lower quadrants and retro alveolar region of the right mamma. The sonographic study informed the presence of a hypoechoic, oval image. The lesion was excised. The pathological and immunohistochemical study showed a breast adenomyoepithelioma. The patient did not have post-surgery complications. Currently she is followed in consultation after seven years of the surgery.

Fibroadenoma vulvar: a propósito de un caso clínico / Vulvar fibroadenoma: about a clinical case

RESUMEN El fibroadenoma vulvar es un tumor benigno poco frecuente con muy pocos casos descritos en la literatura. Por lo general, se diagnostica entre los 20 y 70 años. Tiene un buen pronóstico y rara vez recurre después de la escisión. Presentamos un caso de fibroadenoma vulvar, en una mujer de 33 años, manifestado como un tumor localizado, bien definido de partes blandas en el labio mayor izquierdo. La lesión fue extirpada completamente y la histología confirmó un fibroadenoma con marcador de estrógeno positivo.

ABSTRACT Vulvar fibroadenoma is a rare benign tumor with few cases reported in the literature. It usually occurs between 20 and 70 years of age. It has a good prognosis and rarely recurs following excision. We present a case of vulvar fibroadenoma as a localized, well-defined soft tissue mass in the left labium majus of a 33-year-old woman. The mass was excised completely, and histology demonstrated a fibroadenoma positive for estrogen receptor.

Fibroadenoma de la vulva. A propósito de un caso / Vulvar Fibroadenoma with regards

El fibroadenoma vulvar es una lesión extremadamente rara. Se presenta como una masa unilateral, de tamaño variable, asintomático y ocasionalmente asociado a otras lesiones vulvares o extravulvares y existe gran controversia sobre su origen. Estas lesiones necesitan del examen histopatológico para llegar al diagnóstico definitivo. El comportamiento de este tumor es similar al mamario. La escisión generalmente tiene un buen pronóstico y rara vez recidiva. Presentamos un caso donde se diagnosticó histopatológicamente esta lesión en una mujer de 26 años de edad con masa tumoral en la vulva, a la que se le realizó excéresis quirúrgica.

Vulvar fibroadenoma is extremely rare. It presents as a unilateral mass of variable size, asymptomatic and occasionally associated to other vulvar and extra-vulvar lesions. There is a great controversy about their origin. These lesions need a histo-pathological exam to reach a concluding diagnosis. Its behavior is similar to the breast tumor. Its removal generally has a good prognosis and there is rarely a relapse. This is a case of a 26 year old woman who was histo-pathologically diagnosed a vulvar tumor. A surgical removal was performed.

Fibroadenoma gigante juvenil de mama: presentación de un caso clínico / Giant juvenile fibroadenoma of the breast: a clinical case

El fibroadenoma gigante juvenil es un tumor de mama benigno y una variante rara de los fibroadenomas. La presentación clínica suele ser una masa tumoral indolora en la mama, aislada y unilateral. Representa entre el 0, 5% y el 2% de todos los fibroadenomas y se desconoce su etiología precisa. Sin embargo, se cree que las hormonas son factores contribuyentes. En este artículo presentamos el caso de un fibroadenoma gigante juvenil de 20 cm de diámetro en la mama de una niña de 14 años. La paciente tenía una masa tumoral indolora, que se había agrandado progresivamente durante 1 año. La ecografía reveló la presencia de un fibroadenoma y se realizó una excisión quirúrgica. Tras diez meses de seguimiento, la paciente se encuentra bien.

Juvenile giant fibroadenoma is a benign breast tumor and rare variant of the fibroadenomas. Clinical presentation is usually a painless, solitary and unilateral breast mass. It accounts for 0.5%-2% of all fibroadenomas and exact etiology is not known; however, hormonal influences are thought to be contributing factors. We present a case of a 20 cm diameter giant juvenile fibroadenoma of the breast in a 14-year-old girl. The patient was suffering from a painless, progressively enlarging mass for 1 year. Ultrasound revealed fibroadenoma and total surgical excision was performed. The patient is doing well in ten months of follow up.

Tumor filoide en una mujer indígena colombiana / Phyllodes tumor in a Colombian indigenous woman

Solitary eccrine syringofibroadenoma - Case Report

Eccrine syringofibroadenoma is a rare benign adnexal neoplasm derived from cells of the acrosyringium of eccrine sweat glands. ESFA usually manifests as a solitary nodule on the extremities of elderly patients, but it may also present as papules, nodules or plaques. Its clinical appearance is nonspecific and malignant neoplasms should beconsidered in the differential diagnosis. However, histopathological findings are typical. The main treatment is surgical excision. In order to illustrate a typical presentation of the tumor, we report a case of solitary eccrine syringofibroadenoma, including the surgical treatment used and its result.

Fibroadenoma vulvar: reporte de un caso y revisión de la literatura / Vulvar Fibroadenoma: A case report and review of the literature

Los fibroadenomas son lesiones benignas localizadas usualmente en mama, siendo su localización en zona vulvar bastante rara. Clínicamente se presenta como una masa asintomática, subcutánea, unilateral, de tamaño variable con múltiples diagnósticos diferenciales, por lo cual, el examen histopatógico es necesario para llegar al diagnóstico. Los fibroadenomas vulvares son tumores fibroepiteliales bifásicos conformados por un componente glandular epitelial y otro estromal, similares a los hallados en mama. La histogénesis de este tipo de tumores es incierta. El tratamiento de este tipo de lesión es la resección, siendo su pronóstico excelente. Se presenta un caso de una paciente de 42 años, sin enfermedades de base, la cual presenta una masa asintomática en zona vulvar. (MÉD.UIS. 2014;27(2):93-96).

A fibroadenoma is a benign lesion usually found in the breast. However, it is rare to find it in the vulvar area. It is clinically presented as an asymptomatic, subcutaneous, unilateral lump, of different sizes and with multiple diagnosis, therefore the histopathologic exam is needed to give a diagnosis. Histopathologically, these are biphasic fibroepithelial tumors composed of a glandular epithelial component and a stromal component, similar to those found in the breast. The histogenesis of this type of injuries is unknown. The treatment for this type of injury is the resection, giving an excellent prognostic. We report a case of 42 years-old patient without diseases, who shows a asymptomatic lesion in the vulvar area is presented.(MÉD.UIS. 2014;27(2):93-96).

Clouston syndrome associated with eccrine syringofibroadenoma

Eccrine syringofibroadenoma is a rare benign neoplasia derived from acrosyryngium cells of the eccrine sudoriferous glands. It affects the extremities of elderly individuals as solitary tumors, or may also present as multiple lesions. There are controversies about the pathogenesis and differentiation of the tumor. Eccrine syringofibroadenoma has been associated with subjacent conditions, such as for example, hypohidrotic ectodermic dysplasias. The authors describe a case report of a patient with Clouston Syndrome, who presented papules and nodules in extremities, clinically and histologically compatible with eccrine syringofibroadenoma. There are only three cases described in the literature, associated with Clouston Syndrome, and this is the fourth case.
