RESUMO

SUMMARY: Isolated incidences of human cysticercosis have been reported world-wide, but it remains a major public health concern in endemic areas such as Mexico, Africa, South-East Asia, Eastern Europe, and South America. Cysticercosis most commonly involves the skeletal muscle, subcutaneous tissue, brain, and eyes. The breast is an uncommon site of presentation for cysticercosis. Due to its rare occurrence, breast cysticercosis is often initially mistaken for other common breast lesions such as cysts, abscess, malignant tumours and fibroadenomas. We report a case of breast cysticercosis in a young South African woman.

RESUMO

Phyllodes tumours (PTs) are rare fibroepithelial lesions of the breast that are classified as benign, borderline, or malignant. As little is known about the molecular underpinnings of PTs, current diagnosis relies on histological examination. However, accurate classification is often difficult, particularly for distinguishing borderline from malignant PTs. Furthermore, PTs can be misdiagnosed as other tumour types with shared histological features, such as fibroadenoma and metaplastic breast cancers. As DNA methylation is a recognised hallmark of many cancers, we hypothesised that DNA methylation could provide novel biomarkers for diagnosis and tumour stratification in PTs, whilst also allowing insight into the molecular aetiology of this otherwise understudied tumour. We generated whole-genome methylation data using the Illumina EPIC microarray in a novel PT cohort (n = 33) and curated methylation microarray data from published datasets including PTs and other potentially histopathologically similar tumours (total n = 817 samples). Analyses revealed that PTs have a unique methylome compared to normal breast tissue and to potentially histopathologically similar tumours (metaplastic breast cancer, fibroadenoma and sarcomas), with PT-specific methylation changes enriched in gene sets involved in KRAS signalling and epithelial-mesenchymal transition. Next, we identified 53 differentially methylated regions (DMRs) (false discovery rate < 0.05) that specifically delineated malignant from non-malignant PTs. The top DMR in both discovery and validation cohorts was hypermethylation at the HSD17B8 CpG island promoter. Matched PT single-cell expression data showed that HSD17B8 had minimal expression in fibroblast (putative tumour) cells. Finally, we created a methylation classifier to distinguish PTs from metaplastic breast cancer samples, where we revealed a likely misdiagnosis for two TCGA metaplastic breast cancer samples. In conclusion, DNA methylation alterations are associated with PT histopathology and hold the potential to improve our understanding of PT molecular aetiology, diagnostics, and risk stratification. © 2024 The Authors.

RESUMO

Fibroadenomas are the most common breast lesion in women of reproductive age. During pregnancy and lactation, fibroadenomas can undergo rapid growth in response to hormonal stimulus. These changes may prompt further investigation and/or intervention due to the risk of an underlying phyllodes tumour. We present a case of a female patient who underwent surgical excision of a giant fibroepithelial lesion at 4 months post partum while continuing to breastfeed. The lesion was successfully excised while maintaining lactation. A postoperative milk fistula resolved with non-operative management. There is limited literature on the surgical management of breast lesions in lactating women. This case illuminates the surgical management of breast lesions in an often well informed group of patients who may choose to have surgery while lactating in spite of the increased risk of complications. This case also highlights the need for a holistic approach to maintain the overall health of mother and child.

RESUMO

BACKGROUND: Approximately 50% of breast mucinous carcinomas (MCs) are oval and have the possibility of being misdiagnosed as fibroadenomas (FAs). We aimed to identify the key features that can help differentiate breast MC with an oval shape from FA on ultrasonography (US). METHODS: Seventy-six MCs from 71 consecutive patients and 50 FAs with an oval shape from 50 consecutive patients were included in our study. All lesions pathologically diagnosed. According to the Breast Imaging Reporting and Data System (BI-RADS), first, the ultrasonographic features of the MCs and FAs were recorded and a final category was assessed. Then, the differences in ultrasonographic characteristics between category 4 A (low-risk group) and category 4B-5 (medium-high- risk group) MCs were identified. Finally, other ultrasonographic features of MC and FA both with an oval shape were compared to determine the key factors for differential diagnosis. The Mann-Whitney test, χ2 test or Fisher's exact test was used to compare data between groups. RESULTS: MCs with an oval shape (81.2%) and a circumscribed margin (25%) on US were more commonly assessed in the low-risk group (BI-RADS 4 A) than in the medium-high-risk group (BI-RADS 4B-5) (20%, p < 0.001 and 0%, p = 0.001, respectively). Compared with those with FA, patients with MC were older, and tended to have masses with non-hypoechoic patterns, not circumscribed margins, and a posterior echo enhancement on US (p < 0.001, p < 0.001, and p = 0.003, respectively). CONCLUSION: The oval shape was the main reason for the underestimation of MCs. On US, an oval mass found in the breast of women of older age with non-hypoechoic patterns, not circumscribed margins, and a posterior echo enhancement was associated with an increased risk of being an MC, and should be subjected to active biopsy.

RESUMO

BACKGROUND: Breast fibroadenoma poses a significant health concern, particularly for young women. Computer-aided diagnosis has emerged as an effective and efficient method for the early and accurate detection of various solid tumors. Automatic segmentation of the breast fibroadenoma is important and potentially reduces unnecessary biopsies, but challenging due to the low image quality and presence of various artifacts in sonography. METHODS: Human learning involves modularizing complete information and then integrating it through dense contextual connections in an intuitive and efficient way. Here, a human learning paradigm was introduced to guide the neural network by using two consecutive phases: the feature fragmentation stage and the information aggregation stage. To optimize this paradigm, three fragmentation attention mechanisms and information aggregation mechanisms were adapted according to the characteristics of sonography. The evaluation was conducted using a local dataset comprising 600 breast ultrasound images from 30 patients at Suining Central Hospital in China. Additionally, a public dataset consisting of 246 breast ultrasound images from Dataset_BUSI and DatasetB was used to further validate the robustness of the proposed network. Segmentation performance and inference speed were assessed by Dice similarity coefficient (DSC), Hausdorff distance (HD), and training time and then compared with those of the baseline model (TransUNet) and other state-of-the-art methods. RESULTS: Most models guided by the human learning paradigm demonstrated improved segmentation on the local dataset with the best one (incorporating C3ECA and LogSparse Attention modules) outperforming the baseline model by 0.76% in DSC and 3.14 mm in HD and reducing the training time by 31.25%. Its robustness and efficiency on the public dataset are also confirmed, surpassing TransUNet by 0.42% in DSC and 5.13 mm in HD. CONCLUSIONS: Our proposed human learning paradigm has demonstrated the superiority and efficiency of ultrasound breast fibroadenoma segmentation across both public and local datasets. This intuitive and efficient learning paradigm as the core of neural networks holds immense potential in medical image processing.

RESUMO

Treatment of multiple benign breast nodules is sometimes challenging with respect to establishing a surgical plan that achieves both therapeutic and cosmetic goals. Successful application of oncoplastic techniques has been reported in selected cases of benign breast lesions. In this case report, we present the surgical treatment and outcome of a patient with multiple fibroadenomas in ptotic and voluminous breasts. A combined procedure of extensive glandular resection and reduction mammoplasty using a modified vertical pedicle technique was performed on this patient, who desired complete lesion removal, volume reduction, and mastopexy. The cosmetic result was satisfactory at both the short- and mid-term follow-up. In addition, different techniques applied in the treatment of breast fibroadenoma are herein reviewed and discussed.

RESUMO

PURPOSE: To investigate the utility of whole-tumor histogram analysis based on multiparametric MRI in distinguishing pure mucinous breast carcinomas (PMBCs) from fibroadenomas (FAs) with strong high-signal intensity on T2-weighted imaging (T2-SHi). MATERIAL AND METHODS: The study included 20 patients (mean age, 55.80 ± 15.54 years) with single PBMCs and 29 patients (mean age, 42.31 ± 13.91 years) with single FAs exhibiting T2-SHi. A radiologist performed whole-tumor histogram analysis between PBMC and FA groups with T2-SHi using multiparametric MRI, including T2-weighted imaging (T2WI), diffusion weighted imaging (DWI) with apparent diffusion coefficient (ADC) maps, and the first (DCE_T1) and last (DCE_T4) phases of T1-weighted dynamic contrast-enhanced imaging (DCE) images, to extract 11 whole-tumor histogram parameters. Histogram parameters were compared between the two groups to identify significant variables using univariate analyses, and their diagnostic performance was assessed by receiver operating characteristic (ROC) curve analysis and logistic regression analyses. In addition, 15 breast lesions were randomly selected and histogram analysis was repeated by another radiologist to assess the intraclass correlation coefficient for each histogram feature. Pearson's correlation coefficients were used to analyze the correlations between histogram parameters and Ki-67 expression of PMBCs. RESULTS: For T2WI images, mean, median, maximum, 90th percentile, variance, uniformity, and entropy significantly differed in PBMCs and FAs with T2-SHi (all P < 0.05), yielding a combined area under the curve (AUC) of 0.927. For ADC maps, entropy was significantly lower in FAs with T2-SHi than in PMBCs (P = 0.03). In both DCE_T1 and DCE_T4 sequences, FAs with T2-SHi showed significantly higher minimum values than PBMCs (P = 0.007 and 0.02, respectively). The highest AUC value of 0.956 (sensitivity, 0.862; specificity, 0.944; positive predictive value, 0.962; negative predictive value, 0.810) was obtained when all significant histogram parameters were combined. CONCLUSIONS: Whole-tumor histogram analysis using multiparametric MRI is valuable for differentiating PBMCs from FAs with T2-SHi.

RESUMO

ABSTRACT: Prostate-specific membrane antigen PET imaging has revolutionized the role of prostate cancer diagnosis and management, with very high sensitivity and specificity. To prevent misdiagnosis and for accurate therapy planning, prostate-specific membrane antigen (PSMA) uptake in nonprostatic diseases needs to be recognized correctly. Besides the physiological PSMA expression, 68 Ga-PSMA-11 uptake has been mentioned in multiple oncological and nononcological lesions. The present case report exhibits 68 Ga-PSMA-11 uptake in fibroadenoma in a male accessory breast in the right axillary region.

RESUMO

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.

RESUMO

El fibroadenoma es la lesión benigna fibroepitelial más frecuente de la mama en la mujer joven, correspondiendo alrededor del 90% de las lesiones sólidas de la glándula en la adolescencia. Sin embargo, el fibroadenoma gigante juvenil es una afección de la glándula mamaria poco frecuente, que afecta principalmente a mujeres menores de 18 años. Debido a la similitud de las características clínicas del fibroadenoma gigante juvenil y el tumor filodes, además del rápido crecimiento de ambas entidades, es importante establecer el diagnóstico diferencial de ambas enfermedades cuando se sospeche de alguna de ellas, con la finalidad de garantizar la actitud terapéutica más adecuada. Adolescente de 14 años de edad sin antecedentes familiares ni personales de interés, quien acude remitida a nuestra consulta en septiembre del 2021 en vista de hallazgos ecográficos, por presentar asimetría mamaria a expensas de nódulo mamario izquierdo de 5 meses de evolución. Se realiza biopsia por aguja gruesa ecoguiada con el resultado de fibroadenoma gigante juvenil. Se practicó tumorectomía. El diagnóstico histopatológico se mostró con fibroadenoma gigante juvenil de mama izquierda. Basándonos en la bibliografía consultada y nuestra experiencia, un diagnóstico diferencial temprano y preciso, en conjunto a la extirpación quirúrgica para una correcta caracterización, sería el manejo más adecuado de estas pacientes. La táctica y técnica quirúrgica dependen de la edad al momento del diagnóstico, de las características clínicas y radiológicas de la glándula mamaria y del tumor, e inclusive de los deseos de la paciente.

Fibroadenoma is the most common benign fibroepithelial lesion of the breast in young women, accounting for around 90% of solid lesions of the gland in adolescence. However, juvenile giant fibroadenoma is a rare condition of the mammary gland, which mainly affects women under 18 years of age. Due to the similarity of the clinical characteristics of juvenile giant fibroadenoma and phyllodes tumor, in addition to the rapid growth of both. Entities, it is important to establish the differential diagnóstico of both pathologies when one of them is suspected, in order to guarantee the most appropriate therapeutic approach. A 14-year-old adolescent with no family or personal history of interest, who was referred to our clinic in September 2021 in view of ultrasound findings due to presenting breast asymmetry at the expense of a 5-month-old left breast nodule. An ultrasound-guided core needle biopsy was performed with the result of giant juvenile fibroadenoma. Lumpectomy was performed. Histopathological diagnóstico compatible with juvenile giant fibroadenoma of the left breast. Based on the consulted bibliography and our experience, an early and precise differential diagnóstico, together with surgical removal for a correct characterization would be the most appropriate management of these patients. The surgical tactics and technique depend on the age at the time of diagnóstico, the clinical and radiological characteristics of the mammary gland and the tumor, and even the wishes of the patient.

RESUMO

Breast tubular adenomas (TAs) are rare, benign glandular epithelial tumors that arise from a proliferation of acini in the terminal duct lobular units. In the literature, 40 TA cases have previously been reported, and we describe 5 additional cases in this article. In the small number of reported cases, TAs present most often in women of reproductive age but may also occur in postmenopausal women. Mammographically and sonographically, TAs are almost indistinguishable from fibroadenomas (FAs), and they typically present on US as hypoechoic, oval, circumscribed, parallel masses with variable internal vascularity. TAs can also be seen on mammography as oval masses with microlobulated margins, or as grouped coarse, heterogeneous microcalcifications with or without associated mass or asymmetry. On MRI, TAs present as heterogeneously enhancing, T2-hyperintense oval masses with persistent kinetics. Histopathologically, TAs consist of closely packed round tubules with minimal stroma, in distinction to FAs, which have a prominent stromal component that surrounds and can distort the associated tubules. Because of their benign classification and excellent prognosis, patients with biopsy-confirmed TAs may resume routine screening. Complete surgical excision may be considered for cosmetic purposes or for TAs exhibiting associated suspicious calcifications or rapid growth.

RESUMO

Breast masses are infrequently encountered in pediatric and adolescent populations. Most breast masses in children are benign entities arising from embryological defects which can be managed once breast development is complete. Diagnostic and management dilemmas arise when fibroepithelial lesions of the breast are seen in clinical practice. Differentiation between a fibroadenoma and a phyllodes tumor is important to guide management. Breast cancer in children under 18 years of age is extremely rare and invasive diagnostic testing and aggressive management is only recommended when clinical suspicion of malignancy is very high. Patient and caregiver counseling plays an important role in the management of these diseases. While adult-onset breast diseases have been studied very closely, there is a dearth of literature on pediatric breast anomalies. This review aims to provide a scoping overview of the available literature on benign, fibroepithelial, and malignant lesions of the breast in pediatric and adolescent populations to help guide physicians and surgeons with decision-making regarding the diagnosis and management of pediatric breast diseases.

RESUMO

BACKGROUND: Breast fibroadenomas and phyllodes tumors are both fibroepithelial tumors with comparable histological characteristics. However, rapid and precise differential diagnosis is a tough point in clinical pathology. Given the tendency of phyllodes tumors to recur, the difficulty in differential diagnosis with fibroadenomas leads to the difficulty in optimal management for these patients. METHOD: In this study, we used Raman spectroscopy to differentiate phyllodes tumors from breast fibroadenomas based on the biochemical and metabolic composition and develop a classification model. The model was validated by 5-fold cross-validation in the training set and tested in an independent test set. The potential metabolic differences between the two types of tumors observed in Raman spectroscopy were confirmed by targeted metabolomic analysis using liquid chromatography-tandem mass spectrometry (LC-MS/MS). RESULTS: A total of 204 patients with formalin-fixed paraffin-embedded (FFPE) tissue samples, including 100 fibroadenomas and 104 phyllodes tumors were recruited from April 2014 to August 2021. All patients were randomly divided into the training cohort (n = 153) and the test cohort (n = 51). The Raman classification model could differentiate phyllodes tumor versus fibroadenoma with cross-validation accuracy, sensitivity, precision, and area under curve (AUC) of 85.58 % ± 1.77 %, 83.82 % ± 1.01 %, 87.65 % ± 4.22 %, and 93.18 % ± 1.98 %, respectively. When tested in the independent test set, it performed well with the test accuracy, sensitivity, specificity, and AUC of 83.50 %, 86.54 %, 80.39 %, and 90.71 %. Furthermore, the AUC was significantly higher for the Raman model than that for ultrasound (P = 0.0017) and frozen section diagnosis (P < 0.0001). When it came to much more difficult diagnosis between fibroadenoma and benign or small-size phyllodes tumor for pathological examination, the Raman model was capable of differentiating with AUC up to 97.45 % and 95.61 %, respectively. On the other hand, targeted metabolomic analysis, based on fresh-frozen tissue samples, confirmed the differential metabolites (including thymine, dihydrothymine, trans-4-hydroxy-l-proline, etc.) identified from Raman spectra between phyllodes tumor and fibroadenoma. SIGNIFICANCE AND NOVELTY: In this study, we obtained the molecular information map of breast phyllodes tumors provided by Raman spectroscopy for the first time. We identified a novel Raman fingerprint signature with the potential to precisely characterize and distinguish phyllodes tumors from fibroadenoma as a quick and accurate diagnostic tool. Raman spectroscopy is expected to further guide the precise diagnosis and optimal treatment of breast fibroepithelial tumors in the future.

RESUMO

BACKGROUND: Fibroadenomas are the most common benign breast lesions in women. They present as a unilateral mass and can rapidly enlarge in size through hormonal changes. Fibroadenomas could be classified as small or giant, and as simple or complex. They are classified as 'giant' when the size exceeds 5 cm and/or weight 500 gram; and as 'complex' if one of the following characteristics is present: cysts with a size >3 mm, epithelial calcifications, sclerosing adenosis and papillary apocrine metaplasia. Giant fibroadenomas can cause compression of surrounding breast tissue or breast asymmetry, requiring surgical excision in order to preserve a normal breast shape. CASE: A 26-year-old pregnant woman was referred with a palpable mass of her right breast. The mass rapidly increased in size to a diameter of 13 cm during the second trimester of her pregnancy. A tru-cut biopsy confirmed a fibroadenoma. The rapid growth and compression of normal breast tissues indicated a lumpectomy during her pregnancy. The mass was easily excised without any consequences for the pregnancy. Pathological examination showed a complex giant fibroadenoma. CONCLUSION: A unique case of a pregnant woman with rapid progression of a fibroadenoma that met the criteria of a complex and giant fibroadenoma, was presented. This case emphasizes the importance of timely surgical intervention, even during pregnancy, to prevent permanent breast tissue damage.

RESUMO

OBJECTIVES: The distinction of benign lesions from malign tumors is crucial for the diagnosis and treatment of breast cancers. BACKGROUND: The aim of this study was to investigate the use of miRNAs as plasma biomarkers for the discrimination of malign and benign breast tumors. METHODS: Whole blood samples obtained from 40 individuals in 3 groups designated as invasive ductal carcinoma group, fibroadenoma group and healthy controls were included in this study. The expression levels of 372 miRNAs were determined using RT-PCR.  Results: The comparison of fibroadenoma group with healthy controls revealed an upregulation of thirty miRNAs and downregulation of twenty-nine miRNAs. The comparison of invasive ductal carcinoma (IDC) group with controls has shown that eight miRNAs were upregulated while eleven miRNAs were downregulated. When comparing IDC and fibroadenoma groups, 15 miRNAs were found to be upregulated, while 10 miRNAs were downregulated. Further analysis of these miRNAs aimed to determine their power in distinguishing  IDCs from fibroadenomas. Among the miRNAs analyzed, seven miRNAs have shown sufficient discriminative power, of which three miRNAs, namely miR-637, miR-523-5p and miR-490-3p, have shown a significantly high discriminative power. CONCLUSIONS: Circulating miR-637 and miR-523-5p combination maybe used to discriminate between invasive ductal carcinomas and fibroadenomas. (Tab. 9, Fig. 4, Ref. 30).

RESUMO

Fibroepithelial lesions (FELs) are among the most common breast masses encountered by breast radiologists and pathologists. They encompass a spectrum of benign and malignant lesions, including fibroadenomas (FAs) and phyllodes tumors (PTs). FAs are typically seen in young premenopausal women, with a peak incidence at 20-30 years of age, and have imaging features of oval circumscribed hypoechoic masses. Although some FA variants are especially sensitive to hormonal influences and can exhibit rapid growth (eg, juvenile FA and lactational adenomas), most simple FAs are slow growing and involute after menopause. PTs can be benign, borderline, or malignant and are more common in older women aged 40-50 years. PTs usually manifest as enlarging palpable masses and are associated with a larger size and sometimes with an irregular shape at imaging compared with FAs. Although FA and FA variants are typically managed conservatively unless large and symptomatic, PTs are surgically excised because of the risk of undersampling at percutaneous biopsy and the malignant potential of borderline and malignant PTs. As a result of the overlap in imaging and histologic appearances, FELs can present a diagnostic challenge for the radiologist and pathologist. Radiologists can facilitate accurate diagnosis by supplying adequate tissue sampling and including critical information for the pathologist at the time of biopsy. Understanding the spectrum of FELs can facilitate and guide appropriate radiologic-pathologic correlation and timely diagnosis and management of PTs. Published under a CC BY 4.0 license.

RESUMO

BACKGROUND: Breast fibroadenoma is the most common benign breast tumour. This study aimed to investigate the advantages and disadvantages of endoscopic-assisted resection via a gas-less transaxillary single-port approach for breast fibroadenoma in adolescent patients, compared with a traditional approach. METHODS: The clinical data of 83 patients with breast fibroadenoma treated in our hospital from October 2019 to October 2021 were collected for retrospective analysis. These patients were divided into an endoscopic-assisted surgery (ES) group (n = 39) and a traditional open surgery (OS) group (n = 44) according to the surgical approach. The operative time, intraoperative blood loss, incision length, postoperative complications, and patient satisfaction were compared between the two groups. RESULTS: The surgical cost was (5.1 ± 0.6) thousand Yuan [(0.7 ± 0.1) thousand US dollars] in the ES group and (3.5 ± 2.7) thousand Yuan [(0.5 ± 0.4) thousand US dollars] in the OS group, showing a statistically significant difference (p < 0.001). There was no significant difference in surgical time, intraoperative blood loss, incision length, or the rate of postoperative complications between the two groups. Stratified analysis revealed that the ES group had a significantly shorter operative time [(57.00 ± 10.26) min vs. (78.27 ± 7.63)] (p < 0.001), a smaller incision length [(3.73 ± 0.34) cm vs. (4.42 ± 0.44) cm] (p < 0.001), and a lower complication incidence rate (11.1% vs. 63.6) (p = 0.011) than the OS group in the cases with a nodule number ≥ 3. The satisfaction score using the BREAST-Q scale indicated that psychosocial well-being and patient satisfaction with the breast in the ES group were significantly superior to those in the OS group [(91.18 ± 3.12) points vs. (87.00 ± 4.45) points and (91.03 ± 6.80) points vs. (84.45 ± 6.06) points, respectively] (p < 0.001). CONCLUSION: ES is a safe and effective method for the treatment of fibroadenoma. In patients with multiple fibroadenomas (≥ 3 tumours), ES has a shorter operative time and fewer postoperative complications. ES demonstrates a significant, prominent advantage in cosmetic appearance. However, it should be noted that ES is associated with higher costs than OS.

RESUMO

A female in her early 20s was referred to the breast-endocrine surgeons with a self-detected tender left breast lump on the background of a family history of breast cancer. A physical examination revealed a rubbery and mobile mass in the left upper breast. Ultrasound demonstrated a solid hypoechoic mass with a likely differential diagnosis of fibroadenoma, with a subsequent core needle biopsy (CNB) confirming a fibroadenoma. Given the size and tenderness of the lump, an excisional biopsy was performed. Histology revealed a fibroadenoma with components of low-grade ductal carcinoma in situ, contained within the fibroadenoma and excised with clear margins.Following surgical excision, a multidisciplinary review determined that no further local therapy was required and recommended a genetics referral. This case was interesting as it raised important questions, including what the best surveillance strategies are for female patients with breast cancer within fibroadenoma and determining the risk and probability of missing epithelial atypia via CNB.

RESUMO

PURPOSE: To evaluate the technical success and efficacy rates of US-guided percutaneous vacuum-assisted excision (VAE) of breast fibroadenomas, also assessing procedural complications and long-term patient satisfaction rates. MATERIALS AND METHODS: The institutional database of a tertiary breast cancer referral centre was retrospectively reviewed to retrieve all women with fibroadenomas who underwent US-guided VAE between May 2011 and September 2019. We subsequently included in this study all fibroadenomas with a maximum diameter of 3 cm at US and an available histological confirmation obtained by core-needle biopsy before VAE. Immediately after VAE, technical success (defined as the correct VAE execution) and the occurrence of procedural complications were evaluated. Imaging follow-up (US ± mammography) after 6, 12, 24 and 36 months was performed to evaluate technical efficacy (defined as the absence of fibroadenoma recurrence at 6-month follow-up). Long-term patient satisfaction was evaluated with telephonic interviews in October 2022. RESULTS: We retrospectively included 108 women (median age 46 years) with 110 fibroadenomas diagnosed at core-needle biopsy with a median lesion size at US of 12 mm. Technical success was obtained in 110/110 VAEs (100%). Minor procedural complications (haematomas) occurred in 7/110 VAEs (6%), whereas 8/110 patients had a fibroadenoma recurrence at 6-month follow-up, resulting in a 93% technical efficacy (102/110 VAEs). All patients available for telephonic follow-up (104/104, 100%) reported high satisfaction with VAE results. CONCLUSION: US-guided VAE is a safe and effective procedure for the excision of fibroadenomas, representing a viable alternative to surgery, with a low complication rate and high patient satisfaction.
