Surgical management of a giant fibroadenoma during lactation.

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.

Reduction mammoplasty and mastopexy for multiple bilateral fibroadenomas: a case report and literature review.

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.

A rapidly growing fibroadenoma in a pregnant woman: A case report.

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.

Clinical study on single-port endoscopic resection via a gasless transaxillary approach in the treatment of breast fibroadenoma in adolescents.

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.

Incidental DCIS within a fibroadenoma.

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.

Efficacy and safety of vacuum-assisted excision (VAE) of fibroadenomas: experience in a tertiary centre.

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.

Feasibility and efficacy of ultrasound-guided high-intensity focused ultrasound of breast fibroadenoma.

OBJECTIVE: This nonrandomized prospective clinical trial aimed to assess the efficacy, safety and follow-up outcomes of ultrasound-guided high-intensity focused ultrasound (USgHIFU) surgery in patients with breast fibroadenoma. METHODS: With the approval of the institutional ethics committee and written informed consent, a total of 113 patients diagnosed with breast fibroadenoma by core-needle biopsy in our hospital were recruited. USgHIFU surgery was performed under local anesthesia. Contrast-enhanced ultrasound (CEUS) or contrast-enhanced MRI (CEMRI) was performed to evaluate the nonperfused volume (NPV). The patients were followed up with physical examination and ultrasound imaging. RESULTS: The clinical outcome of 85 patients with 147 fibroadenomas with a follow-up time of more than 3 months was analyzed in this study. Fifty-two patients had one lesion, twenty-one patients had two lesions and twelve patients had more than two lesions. During USgHIFU, the median localization time for all fibroadenomas was 3 (interquartile range: 1, 5) min, and the median treatment time was 9 (interquartile range: 5, 15) min. Under local anesthesia, all the patients tolerated the treatment well. No serious epidermal burns were observed in any of the patients. Based on CEUS or CEMRI imaging evaluation, the median NPV ratio was 100% (interquartile range: 79.2%, 116.8%). The VRR were 26.77 ± 50.05%, 50.22 ± 42.01% and 72.74 ± 35.39% at 3-6 months, 6-12 months and >12 months, respectively, which showed significant statistical difference (p < .001). CONCLUSION: Ultrasound-guided HIFU surgery is an effective and safe noninvasive alternative technique for the treatment of breast fibroadenoma.

Oncoplastic Breast Reconstruction for Large Pediatric Breast Tumors: A Case Series.

ABSTRACT: Large breast fibroadenomas in pediatric females may cause discomfort, asymmetry, and psychological stress, and patients may elect for surgical excision. There are no criteria for reconstruction after the excision of these masses, and the research is limited in describing oncoplastic techniques in pediatric fibroadenoma excision. Nononcoplastic techniques, such as mastectomy with implant or flap reconstruction, have been used for pediatric fibroadenoma excision reconstruction. Oncoplastic techniques using Wise pattern or circumareolar incisions have shown to have efficacious outcomes. In addition, pediatric females undergoing breast surgery risk long-term complications such as continued breast asymmetry due to further breast growth, nipple and breast hypoesthesia, and future breastfeeding difficulty. This case series describes the oncoplastic techniques used for large benign mass excision and reconstruction of 3 pediatric females. A Wise pattern technique was used for all 3 patients, and 2 underwent a free-nipple graft. Oncoplastic techniques for pediatric breast mass excision provide satisfactory aesthetic outcomes with minimal surgical morbidity. Further research assessing the long-term effects of pediatric breast mass excision and reconstruction would be beneficial.

Clinicohistopathological study of benign breast lesions in surgically excised specimens in a tertiary care hospital.

Background: Distinguishing benign breast diseases (BBDs) from malignant breast diseases is a worrisome entity and should also have knowledge of the pattern of occurrence of the disorders in their geographical location. This research aimed to study the clinical and histopathological pattern of BBD in Indian patients. Materials and Methods: The study was conducted on 153 specimens from lumpectomy, core needle biopsy, and mastectomy. Data regarding patients' age, sex, presenting complaints, duration of the complaints, and history of menstrual cycles and lactation were collected from the biopsy requisition forms and case papers. The tissue bits were processed and stained with hematoxylin and eosin, and a histopathological examination was performed. Results: Most of the patients in the present study were females (n = 151, 98.7%). The mean age of the patients was 30.45 years. Most of the BBD cases (n = 118, 77.14%) were benign, of which fibroadenoma (101 cases) accounted for 66%. Majority of the lesions were in the upper outer quadrant (39.22%). Of the 153 cases, 94 cases of fibroadenoma, one case of breast abscess, nine cases of fibrocystic change, four cases of phyllodes, three cases of lipoma, and one case of gynecomastia diagnosed clinically correlated well with histopathology (n = 112, 73%). Conclusion: BBDs are mostly seen in female patients in the age group of 21-30 years. Fibroadenoma is the most common BBD. Clinical assessment followed by histopathological examination provided an accurate diagnosis. The clinical diagnosis correlated well with histopathology.

Bilateral Multiple Giant Juvenile Fibroadenomas in an Adolescent Girl.

Giant juvenile fibroadenomas are usually seen as rare variants of fibroadenomas in adolescents as unilateral solitary masses that may be managed by surgical excision with conservation of normal breast tissue. We report a case of a premenarchal 13-year-old female presenting with bilateral multifocal giant juvenile fibroadenomas requiring essentially bilateral subtotal nipple sparing mastectomies. Surgical evaluation revealed replacement of normal breast tissue on the right side. She then had development of two additional right-sided fibroadenomas requiring excision.

Robotic system for magnetic resonance imaging-guided high-intensity focus ultrasound application: Feasibility of breast fibroadenoma treatment.

PURPOSE: This paper presents a high-intensity focus ultrasound (HIFU) robotic system for treating breast fibroadenoma under the guidance of magnetic resonance imaging (MRI). Based on the thermal and mechanical effects of ultrasound, the system aims to deliver ultrasound energy to a target precisely without damaging the normal tissue. The temperature elevation can be monitored in real time by MRI, and the treatment plan can be adjusted during the procedure. The requirements, design specifications, control system and registration of the robotic system are specified. METHODS: The robotic system was designed with a 3 degrees of freedom manipulator with limit switches and encoders, a customised MRI-compatible breast coil, a water bladder with sets of breast-conforming brackets, and a probe capable of generating ultrasound. Twenty volunteers were recruited for this study, and their data were analysed to provide more precise data for the design. The accuracy of the robot was evaluated in free space using a coordinate measuring machine, phantom and ex vivo porcine tissue in MRI room. The study also verified the signal-to-noise ratio (SNR) of the MRI with the effect of the robotic system. RESULTS: The research findings revealed that the manipulator exhibited a translational precision of 0.10 ± 0.14 mm, a rotational fidelity around the X direction of 0.11 ± 0.09°, and an oscillatory exactness around the Y direction of 0.10 ± 0.08°. The investigation of positioning accuracy demonstrated that the robot's error in free space was 0.26 ± 0.07 mm. When subjected to MRI room with agar-silica phantom and ex vivo porcine tissue, the positioning accuracy amounted to 1.11 ± 0.47 mm and 1.57 ± 0.52 mm. In the presence of the robotic system, the SNR of the MRI experienced a 4.2% reduction, which had a negligible impact on image quality. CONCLUSIONS: The conducted experiments validate the efficacy of the proposed MRI-guided HIFU robotic system in executing agar-silica phantom and ex vivo porcine tissue investigations with adequate positioning accuracy. Consequently, this system exhibits certain feasibility for the treatment of breast fibroadenomas.

The largest and heaviest giant juvenile fibroadenoma of the breast in the Chinese population: A case report.

RATIONALE: Fibroadenoma is the most common benign tumor of the breast, but giant juvenile fibroadenoma exceeding 20 cm is much rare. This report presents the largest and heaviest giant juvenile fibroadenoma in an 18-year-old Chinese girl. DIAGNOSIS AND INTERVENTIONS: An 18-year-old adolescent girl with a 2-year history of a large left breast mass with progressive expansion over 11 months. A 28 × 21 cm soft swelling occupied the entire outer quadrants of the left breast. The huge mass sagged below the belly button, resulting in high asymmetry of the shoulders. Contralateral breast examination results were normal except for hypopigmentary detected on the nipple-areola complex. Under general anesthesia, the lump was completely excised along the outer envelope of the tumor, while reserving excessive resection of the skin. The patient's postoperative recovery was uneventful, and the surgical wound healed well. OUTCOMES: A radial incision operation was finally performed to remove the huge mass and to preserve the normal breast tissue and the nipple-areolar complex, not only considering the aesthetics but also preserving the ability to lactate. LESSONS: Currently, there is a lack of clear guidelines regarding the diagnostic and treatment modalities for a giant juvenile fibroadenoma. The principle of surgical choice is to balance aesthetics and function preservation.

"Growing fibroadenoma": Are there clinical and pathological features predicting a phyllodes tumor on surgical excision?

In cases of growth of FA on imaging, core needle biopsies (CNB) are often performed to rule out phyllodes tumor (PT). We aim to focus on "growing FAs" and to identify clinical and histopathologic features that are likely to predict a PT on excision. Thirty-four FAs with radiologic documentation of growth were included. Various clinical and pathological features such as age, body mass index (BMI), lesion size, and growth rate were recorded. On excision, 17 cases (50 %) were FAs, whereas 16 (47 %) were re-classified as benign PT despite only 19 % being suspicious for PT on CNB. PT patients were older (mean age 42.6) than those with FAs (mean age 28.2), p = 0.0002. All false negative cases demonstrated intracanalicular growth. Mitotic rate was the most significant histologic feature in PT on excision compared to others, such as lesion circumscription and stromal cellularity. Recognition and careful counting of mitotic rate, especially with intracanalicular patterns in growing FAs, can potentially prevent missing a PT on CNB. In patients with "growing FAs" who are ≥40 years of age, excision may be recommended due to the high likelihood of PT diagnosis on excision and high false negative rate on CNB.

Fibroadenoma in axillary breast tissue - Utility of rapid on-site evaluation & report of two cases.

ABSTRACT: Fibroadenoma of axillary breast tissue presents as a palpable mass, cyclic pain in the axilla, and with asthetic concerns. Axillary breast tissue can occur anywhere along the primitive embryonic milk lines, extending from the axilla to the groin, and can present unilaterally or bilaterally. The reported incidence of axillary breast tissue is 0.4%-6% in females. We had two cases of fibroadenoma in the axilla that were diagnosed on rapid on-site evaluation and later confirmed by routine cytology stains in young females. We report the cases for their rarity and high degree of clinical suspicion in the young reproductive age group female. We also emphasize the utility of ROSE in cytopathology.

Fibroadenoma of the breast; incidence of malignancy and indicators for surgical intervention: An analysis of 1392 patients.

BACKGROUND: Fibroadenomas are common among young females. The size of the lesion used to be an indication for further assessment or excision. With arising of the watch and see proponents, criteria for selecting patients are important to establish. METHODS: This is a retrospective study of a prospectively maintained database where all patients having the clinical/radiological provisional diagnosis of fibroadenoma and attending our center - from January 2008 to March 2020 - were enrolled. The primary outcome was the incidence of malignancy and the secondary outcomes were the correlation of malignancy-risk with epidemiologic and radiologic criteria. RESULTS: The study enrolled 1392 patients. The mean age of the patients was 35.7 + ∕- 13.1 years. The median of the longest diameter of the detected breast lesions was 25 mm. The incidence of malignancy was 188 (13.5%). The size of the lesion measured by largest diameter was insignificant (p = 0.99), while the patients' age, marital status, and imaging criteria as measured by BIRADS score were significant (<0.001). CONCLUSION: Approaching patients with the age above 35 or with BIRADS 4 provisionally diagnosed with fibroadenomas should be cautious with biopsy and short-term follow-ups The size of the tumor alone should not be used as an indication for surgical intervention.

Fibroadenoma: a guide for junior clinicians.

Fibroadenoma is the most common cause of benign breast lumps and is typically seen in women under the age of 40 years. Fibroadenomas are classified as simple, complex, giant, myxoid or juvenile. They present as smooth, rubbery, mobile masses on palpation. Ultrasonographic and mammographic features typical of fibroadenomas include solid, round, well-circumscribed masses, with or without lobulated features. They are predominantly treated conservatively although clinical pathways recommend referral for triple assessment. Surgical intervention is indicated by the presence of one or more of the following features: the presence of symptoms, a diameter greater than 2 cm, rapid growth rate, complex features, disease recurrence or patient anxiety.

Fibroadenoma gigante juvenil y cirugía de reconstrucción: reporte de un caso y revisión de la bibliografía / Giant juvenile fibroadenoma and reconstruction surgery: A case report and literature review

El fibroadenoma es la lesión mamaria benigna más frecuente en la mujer joven, siendo el fibroadenoma gigante juvenil una entidad que aparece principalmente en menores de 25 años. Con una etiología actualmente no bien establecida, se caracteriza por ser una lesión tipo masa mayor de 5cm que puede ocupar más del 80% de la mama y que presenta un importante crecimiento con las consecuencias físicas y psicológicas que ello conlleva. A pesar de ser una lesión benigna, su evolución progresiva con un rápido crecimiento obliga a descartar malignidad, lo cual ocurre en menos del 0,2% de los casos. El diagnóstico se basa en una correcta anamnesis, exploración física y pruebas complementarias, siendo preferible la ecografía. El estudio anatomopatológico mediante biopsia permite confirmar el diagnóstico clínico de benignidad o descartar malignidad ante una evolución sospechosa. El tratamiento es quirúrgico y consiste en la escisión completa de la lesión variando la técnica quirúrgica realizada (desde cirugía conservadora hasta mastectomía con reconstrucción) según el tamaño de la lesión, las características de la mama y la edad de la paciente. (AU)

Fibroadenoma is the most common benign breast lesion in young women, being the giant juvenile fibroadenoma an entity that appears mainly in those under 25 years. With an etiology currently not well established, it is described as a mass type lesion greater than 5cm or that occupies more than 80% of the breast and presents significant growth, with the physical and psychological consequences that this entails. Despite being a benign lesion, its fast evolution and growth makes it necessary to rule out malignancy, which occurs in less than 0.2% of the cases. The diagnosis is based on a correct anamnesis, physical examination and complementary tests, preferable with ultrasound. The anatomopathological study by biopsy allows to confirm the clinical diagnosis of benignity or to rule out malignancy in the event of a suspicious evolution. Its management is surgical and consists of complete excision of the lesion, varying the surgical technique performed (from conservative surgery to mastectomy with reconstruction) according to the size of the lesion, the characteristics of the breast, and the age of the patient.

Evaluating the learning curve of high intensity focus ultrasound for breast fibroadenoma by CUSUM analysis: a multi-center study.

OBJECTIVE: To explore the learning curve of high intensity focus ultrasound (HIFU) treatment for breast fibroadenoma. METHODS: A database of 110 patients with 255 breast fibroadenomas who underwent HIFU treatment at two different clinical centers (Center 1 and 2) were retrospectively analyzed. The learning curves of HIFU treatment for breast fibroadenoma were drawn by CUSUM analysis in two centers, respectively. According to the inflection point of the learning curves, the treatment was divided into two groups: initial phase and consolidation phase. HIFU treatment parameters were compared between two groups. The effectiveness and safety results were also evaluated. RESULTS: The inflection points of the learning curves were the 60th treatment in Center 1 and the 65th treatment in Center 2. The screening time, treatment time, sonication time and hyperechoic scale change time were significantly shorter in consolidation phase than those in initial phase of the two centers (p < 0.05). There were no differences in non-perfused volume (NPV) ratio and energy effect factor (EEF) between the two groups in Center 1, while in Center 2, these above-mentioned results in consolidation phase led to a greater improvement than those in initial phase. There was no difference of Visual Analogue Scale (VAS) scores and no adverse event observed in both centers. CONCLUSION: HIFU treatment for breast fibroadenoma was effective and safe. The learning curve of HIFU treatment for breast fibroadenoma can be completed after treating 60-65 tumors without increasing the safety risk.
