RESUMO
Giant fibroadenomas are common in young females and are rarely reported in perimenopausal or menopausal females. These fibroadenomas are observed as single, mobile, small to large, with distinct boundaries. These tumors are hyperplastic and characterized by their aberrant growth in both the epidermal and mesenchymal layers, which can be accompanied by pain in some instances. These tumors have similar clinical resemblances to other epithelial and stromal tumors, such as phyllodes tumors, except for the level of disease severity and malignancy. Treatment of giant fibroadenomas includes surgical resection. Surgical excision is done by complete excision of the fibroadenoma, with the rest of the breast tissue and the nipple-areolar complex preserved. Timely diagnosis can be helpful in the prevention of adverse outcomes. This is a case of a 40-year-old female who presented with a lump in her right breast, for which she underwent a wide local excision. On histopathology, it was found to be a giant fibroadenoma. Her postoperative recovery was uneventful.
RESUMO
Benign breast diseases are a common presentation in the breast clinic outpatient department. These diseases, including giant fibroadenoma, multiple fibroadenoma in different quadrants, and large or recurrent phyllodes tumors, pose challenges in surgical management. We present a case series of 16 patients aged 19 to 63 years (average age, 41.5 years) who presented with breast lumps and underwent surgery using the round block technique for benign breast diseases at our institute between November 2019 and March 2024. Prior to surgery, all patients had clinical, radiological, and pathological assessments. Age, duration of lump, and detailed menstrual, obstetric, and family history of each patient were recorded. Eight (50%) of the patients had phyllodes tumor, four (31.25%) had fibroadenoma, three (18.75%) had both fibroadenoma and phyllodes tumor, and one (6.25%) had adenolipoma. The average size of tumors was 7.5 cm in our study. During postsurgical follow-up, none of the patients had nipple areola necrosis, and they reported that nipple sensation was acceptable. A mastectomy was avoided in all circumstances. Good cosmetic outcomes and clear margin status are achievable using the round block technique.
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.

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.

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.

Fibroadenomas are common benign breast tumors. Fibroadenomas that exceed 5 cm in diameter, weigh more than 500 g, or replace more than four-fifths of the breast are characterized as giant. A fibroadenoma diagnosed in patients during childhood or adolescence is characterized as juvenile. An extensive PubMed search of the literature in English up until August 2022 was performed. In addition, a rare case of a gigantic fibroadenoma in an 11-year-old premenarchal girl who was referred to our adolescent gynecology center is presented here. Eighty-seven cases of giant juvenile fibroadenomas have been reported in the literature along with our case. Patients with giant juvenile fibroadenoma presented at a mean age of 13.92 years and usually after menarche. Juvenile fibroadenomas are usually unilateral, occurring either in the right or the left breast; the majority of them are diagnosed when they are already more than 10 cm in size, and they are most frequently treated with total lump excision. Differential diagnosis includes phyllodes tumors and pseudo-angiomatous stromal hyperplasia. Conservative management is feasible, but surgical excision is recommended to patients with suspicious imaging features or when the mass grows rapidly.
RESUMO
Giant juvenile fibroadenomas, encountered usually in adolescents, are rapidly growing benign breast masses which lead to discomfort, anxiety and significant psychological stress. The breasts are in their early formative years, and thus, it is important to rule out malignancy as well as plan treatment options to preserve as much breast tissue as is possible. This report highlights a case of giant juvenile fibroadenoma diagnosed in a 12-year-old female child and our endeavour to achieve a good aesthetic result.

Giant fibroadenomas are uncommon benign lesions, defined as fibroadenomas of >5 cm in size and/or weighing more than 500 g. They can distort the shape of the breast and cause asymmetry, so they should be excised. Here, we report two cases of giant fibroadenoma, where wide local excision and reconstruction with lateral oncoplasty were done. Compared to all previous reports of patients with giant fibroadenoma, where the lump was excised either through a submammary incision or by round block technique depending on the location of the tumour, we used the lateral oncoplasty technique in both patients. Lateral oncoplasty is a new reconstructive option to maintain cosmesis and symmetry after the excision of giant fibroadenomas in the outer and central quadrants of the breast. It is a good option for reconstruction in cases where the defect is very large and facilities for conventional flap surgeries are not available.
RESUMO
INTRODUCTION: Fibroadenoma is the most common benign lesion of breast in young women, characterized by an aberrant proliferation of both epithelial and mesenchymal elements. It is termed giant fibroadenoma when it is larger than 5â¯cm or weighs more than 500â¯g with an incidence of 0.5-2% of all fibroadenomas. PRESENTATION OF CASE: In this report, we discuss a case of a 13-year-old Pakistani girl who presented with a giant juvenile fibroadenoma in left breast and was treated by a subareolar lump excision through a periareolar incision with excellent cosmetic outcome. To the best of our literature search, this is the first case of giant juvenile fibroadenoma in an adolescent being reported from Pakistan. DISCUSSION: Surgical management of giant juvenile fibroadenoma in immature breast is challenging as it may either result in asymmetric defect or damage to developing breast tissue resulting in long term poor outcomes. Surgical decision should be carefully undertaken and reported for future reference in such cases. CONCLUSION: The diagnosis and management of giant juvenile fibroadenoma can be challenging because these tumors clinically and histologically mimic phyllodes tumor due to their rapid growth and large size. Excision through a periareolar approach for fibroadenomas located in subareolar region provides good cosmetic results in these patients with minimal scar visibility.
RESUMO
INTRODUCTION: Fibroadenomas of the breast present as two phenotypic variants. The usual variety is 5 cm or less in diameter and there is another large variant called giant fibroadenoma which is greater than 5 cm in diameter. Despite of its large size, it is not malignant. The aim of our study is to determine whether this large variant is different from the usual fibroadenoma in terms of its biological pathways and biomarkers. METHODS: mRNA was extracted from 44 fibroadenomas and 36 giant fibroadenomas, and transcriptomic profiling was performed to identify up- and down-regulated genes in the giant fibroadenomas as compared to the fibroadenomas. RESULTS: A total of 40 genes were significantly up-regulated and 18 genes were significantly down-regulated in the giant fibroadenomas as compared to the fibroadenomas of the breast. The top 5 up-regulated genes were FN1, IL3, CDC6, FGF8 and BMP8A. The top 5 down-regulated genes were TNR, CDKN2A, COL5A1, THBS4 and BMPR1B. The differentially expressed genes (DEGs) were found to be associated with 5 major canonical pathways involved in cell growth (PI3K-AKT, cell cycle regulation, WNT, and RAS signalling) and immune response (JAK-STAT signalling). Further analyses using 3 supervised learning algorithms identified an 8-gene signature (FN1, CDC6, IL23A, CCNA1, MCM4, FLT1, FGF22 and COL5A1) that could distinguish giant fibroadenomas from fibroadenomas with high predictive accuracy. CONCLUSION: Our findings demonstrated that the giant fibroadenomas are biologically distinct to fibroadenomas of the breast with overexpression of genes involved in the regulation of cell growth and immune response.

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.

Giant fibroma of the breast in adolescence is a benign tumor of the breast that occurs in a special period in women, often in adolescent women aged 18-25 years old. These tumors are characterized by short course and large size. They are rare in clinic and easy to be misdiagnosed. We report a case of 22 cm-pubertal breast giant fibroadenoma which underwent inverted "T" incision resection. The diagnosis, pathological characteristics, and treatment of adolescent giant fibroadenoma of the breast are also discussed based on literature.

Purpose: The removal of the giant breast fibroadenoma (GFA) with esthetic repair of the severe deformed breast is a surgical challenge. Materials and Methods: This was a retrospective study of data of 10 patients with GFAs who treated with a modified round block technique at the Department of Breast Surgery, Hangzhou First People's Hospital (Hangzhou, Zhejiang province, China) from March 2014 to June 2017. Preoperatively, according to the degree of excess skin and asymmetry, a four-point approach was designed. The area between the inner and outer circles was de-epidermized. The tumors were entirely stripped off along the capsule through an incision on a part of the outer circle. To avoid the nipple-areola complex widening, purse-string suture technique was used. Results: Patients' age ranged from 12 to 32 years (mean age, 23 years), and the largest tumor weighed 2 kg, with a diameter of 16.5 cm. After a mean follow-up of 25 months (range, 9-32 months), no local recurrences were found. Cosmetic results were satisfactory with breast symmetry and minimal scarring. Complications were minimal and widening of the periareolar scar was slight as well. Conclusion: The modified round block technique is recommended to resect GFA in order to improve the cosmetic results with minimal scar.

A 19-year-old girl presented with a lump in her right breast and with a history of surgery for the similar complaint 3 years back. Ultrasound was suggestive of benign solitary lesion of size 16 cm × 10 cm. Core biopsy was suggestive of phyllodes tumor, and the histopathology report of previous surgery was also suggestive of phyllodes tumor. Wide excision of the tumor and reconstruction was done with batwing mastopexy and with a slight modification of the described technique so that to avoid contralateral reduction mammoplasty in a young unmarried girl. Postoperative histopathology was suggestive of fibroadenoma measuring 15 cm × 8 cm with all margins free of tumor, and it is probably one of the biggest fibroadenomas reported so far. On follow-up, no significant disparity noted between the appearances of both breasts.

INTRODUCTION: Fibroadenomas are common benign lesions of the breast that are usually found young patients. Giant fibroadenomas are uncommon benign lesions, defined as fibroadenomas of >5â¯cm in size, which are usually found in patients of less than 20 years of age. PRESENTATION OF CASE: A 39-year-old premenopausal woman presented with a right breast tumor that had rapidly increased in size and which showed ulceration and bleeding. Needle biopsy showed mixed connective tissue and an epithelial tumor without a leaf-like pattern, but indeterminate. Total mastectomy and skin grafting were performed. Histopathology confirmed the diagnosis of giant fibroadenoma. DISCUSSION: In comparison to all previous reports on patients with giant fibroadenoma, this patient was relatively old and the etiology was unknown. Although rare, an appropriate therapeutic strategy should be decided according to the results of a histopathological examination. CONCLUSION: Early treatment could allow breast preserving surgery and patients should be recommended to undergo reexamination with awareness of progression.
RESUMO
Malignant phyllodes may transform from benign phyllodes; low-aggressive malignant phyllodes tumor is manageable by locally wide excision.
RESUMO
Objective: Oncoplastic surgery was developed to allow for large tumor excision and immediate breast reconstruction with the goal of optimal breast shape and symmetry. Although initially used in women who underwent lumpectomy for breast malignancy, these techniques can be useful for cosmetic issues caused by benign breast disease. We describe a modification of an inferior pedicle with Wise-pattern reduction mammoplasty for oncoplastic reconstruction of a giant fibroadenoma. Methods: A 30-year-old woman with size 32 DD breasts was referred by the surgical oncologist with a biopsy-proven fibroadenoma of the right breast. Surgical oncology excised the mass, and immediate reconstruction was performed with an inferolateral pedicle Wise-pattern reduction technique. Results: Immediately postoperatively, the patient showed excellent symmetry. Follow-up postoperatively showed good wound healing, preserved symmetry, and a viable, sensate nipple. Conclusions: Oncoplastic breast reconstruction in a reduction pattern technique after giant fibroadenoma removal provides an excellent outcome, allowing for improved symmetry.
RESUMO
Resumen ANTECEDENTES: El fibroadenoma gigante es raro; suele aparecer en mujeres entre 10 y 18 años. Se caracteriza por el crecimiento rápido de una tumoración encapsulada. De 0.5 a 4% corresponden a una forma especial descrita como fibroadenoma gigante o juvenil. La ecografía es el método de elección para el diagnóstico primario. Si bien la causa principal de una masa asimétrica mamaria en niñas es benigna, la extirpación quirúrgica temprana es la mejor manera de asegurar un buen resultado estético. CASO CLÍNICO: Paciente femenina de 12 años, llevada a la consulta debido al aumento de tamaño de la mama izquierda en el lapso de los tres meses previos. Sin antecedentes personales de importancia, sin cirugías previas, sin consumo de medicamentos y sin alergias conocidas. En la exploración física se apreció la asimetría de las mamas debido al aumento de tamaño de la izquierda; la forma de la areola y el pezón sin alteraciones. Se palpó una tumoración de bordes delimitados, consistencia homogénea blanda que ocupaba toda la glándula mamaria de aproximadamente 20 cm. CONCLUSIONES: El fibroadenoma juvenil es una lesión de crecimiento rápido y exponencial que distorsiona la asimetría y afecta la calidad de vida de la paciente. Es importante establecer el diagnóstico diferencial con tumoraciones mamarias para poder aclarar las dudas de nuestras pacientes acerca de su pronóstico. En pacientes jóvenes es importante tener en cuenta un solo acceso para la reconstrucción.
Abstract BACKGROUND: Giant fibroadenoma is rare; It usually appears in women between 10 and 18 years old. It is characterized by the rapid growth of an encapsulated tumor. From 0.5 to 4% correspond to a special form described as giant or juvenile fibroadenoma. Ultrasound is the method of choice for primary diagnosis. Although the main cause of an asymmetric mammary mass in girls is benign, early surgical removal is the best way to ensure a good aesthetic result. CLINICAL CASE: Female patient of 12 years, taken to the consultation due to the in-crease in size of the left breast in the span of the three previous months. No significant personal history, no previous surgeries, no medication and no known allergies. On physical examination, the asymmetry of the breasts was seen due to the increase in size of the left; the shape of the areola and nipple without alterations. A tumor of delimited edges was palpated, smooth homogenous consistency that occupied the entire mam-mary gland of approximately 20 cm. CONCLUSIONS: The juvenile fibroadenoma is a rapidly growing and exponential lesion that distorts the asymmetry and affects the quality of life of the patient. It is important to establish the difference diagnosis with mammary tumors in order to clarify the doubts of our patients about their prognosis. In young patients it is important to consider only one access for reconstruction.
RESUMO
Objective To compare the effect between Mammotome minimally invasive surgery and traditional surgery in resection of youth giant breast fibroadenoma (YGBF).Methods We randomly selected 73 patients who had YGBF and already accepted surgical treatment in our hospital from Jul.2009 to Jan.2016.The 75 patients recruited from screening programmes were alloted to either treatment according to their choice (37 cases in MS and 38 cases in traditional surgery).The median follow-up was 18 months (from 6 to 36 months).Comparative analysis was done between the two groups in operation time,incision healing time,incision length,intraoperative bleeding,wound infection,subcutaneous hematoma,residual tumor,breast deformation,scar size,and patient satisfaction degree.Results There was no statisticaly significant difference betwen these two groups in operation time,intraoperative blood loss,incision infection,subcutaneous hematoma,or residual tumor (P>0.05),however,MS group was superior to traditional surgery group in the incision healing time,incision length,breast deformation,scar size and postoperative satisfaction degree,and the difference was statistically significant(P< 0.05).Conclusion The advantage of Mammotome minimally invasive operation auxiliary for YGBF is obvious,such as fast wound healing,small incision,infection rate,small breast without deformation and scar etc.,also higher satisfaction degree to the treatment,which is regarded as the preferred surgical treatment for YGBF patients.
