Descripción de un caso: ¿es factible realizar una biopsia selectiva de ganglio centinela en tumores de mama originados en el tejido ectópico axilar?

Breast cancer on axillary ectopic breast tissue is very rare, representing 0.3-0.6% of malignant breast cancers. Therefore, its early diagnosis is a real challenge. In this case, we describe a breast cancer on left axillary ectopic tissue in a 36-year-old female patient, who underwent local surgery with excision of the tissue. When approaching the nodal study of this patient, the possibility of selective study of the sentinel lymph node was considered. The absence of validated clinical guidelines in these cases and the exhaustive review of the literature led the multidisciplinary tumour committee of our hospital, the Hospital Clínico de Santiago de Compostela, to adopt the decision to attempt to perform this technique, adapting it, however, to this particular case. A double tracer was used, injecting technetium-99m in the periareolar area of the left breast and patent blue in the intratumoral area of the axillary ectopic tissue to determine whether both the breast and the tumour had the same lymphatic drainage pathways.Finally, 7 sentinel nodes and 1 palpable non-sentinel node were detected, of which the first was marked with both technetium-99m and patent blue, 4 with the radioisotope only, and 2 stained with patent blue. Two macrometastases were detected intraoperatively in the sentinel nodes, stained only with patent blue, while the rest were negative. The tumour committee took the decision to treat the axilla with radiotherapy. It is therefore concluded that in these cases the periareolar lymphatic drainage and that of the tumour itself may be different, so it would be advisable to use the double tracer injected in different areas to correctly identify the sentinel lymph node. The literature available for this type of situation is scanty and there are no approved clinical guidelines to support our therapeutic decisions, so it would be essential to study breast cancer in infrequent locations, in depth, in order to achieve protocols standardised by international societies that would serve as a benchmark for the management of these cases.

Primary ectopic breast carcinoma: a case report

BackgroundEctopic breast tissue is present in 2–6% of women. Ectopic mammary tissue can experience physiological changes and the same pathological processes as the eutopic breast. Ectopic breast cancer represents an uncommon condition accounting for 0.3% of all breast neoplasms, and it is most frequently located in the axilla.Case reportWe report a rare case of a 57-year-old Tunisian woman who presented with a left-sided axillary mass evolving for about 1 month. The axillary ectopic breast tissue containing the mass was excised with axillary dissection. Pathology revealed a medullary multifocal carcinoma and metastasis was detected in two lymph nodes. She had local radiotherapy after six cycles of chemotherapy. She received herceptin therapy and hormonotherapy. After a 2-year follow-up, no evidence of local recurrence or distant metastases have been identified.ConclusionEctopic breast carcinoma is a rare entity that should be the first diagnosis to be considered if an axillary lump is present in ectopic breast tissue. No particular guidelines on diagnosis and treatment are available. Therefore, physicians should be aware of this condition to avoid treatment delays. Once diagnosed, careful patient follow-up is essential because of the ambiguous natural history of this rare entity.

Axillary ectopic breast tissue in the adolescent.

Ectopic breast tissue (EBT) includes a spectrum of disease that entails other entities based on the presence of glandular tissue, nipple, or areola. The diagnosis in adolescents is infrequent. A retrospective study was performed including girls with axillary EBT (class IV or V of Kajava's Classification) operated in 2006-2020. Imagining studies, clinical and surgical reports, and histopathology were reviewed. Eleven girls from 13 to 16years old were included. Two patients (18.2%) presented bilateral EBT. The most frequent clinical manifestation was 2-5cm mass (100%), associating cyclic pain with menstruation (45%) and fluctuating volume (36%). Bilateral axillary ultrasonography allowed preoperative diagnosis. All of them were treated by open excision, through small incisions located in an axillary y fold. Clinical and aesthetic results were self-assessed as "very good", with normalization of the axillary y hollow and imperceptible scars. No recurrences were observed after one year of follow-up. An immediate postoperative hematoma was reported, which did not require drainage. Histopathology showed mature breast tissue without atypia. Axillary accessory breasts must be included in differential diagnosis of pediatric axillary masses. Bilateral ultrasonography is recommended for the preoperative diagnosis. Excision through minimal incision at this age seems to be safe and effective.

Axillary Ectopic Breast Tissue Primary Cancer: A Rare Presentation of a Common Disease

Background: Carcinoma of ectopic breast tissue represents a rare condition. Ectopic glandular tissue is frequently located in the axilla, so ectopic breast lesions must be distinguished from other subcutaneous masses arising in this location. Case presentation: We describe the case of e 75 y/o woman presented to our department for the recent manifestation of an axillary cutaneous lesion. She underwent mammogram, breast ultrasound, fine-needle aspiration citology, breast MRI, thoraco-abdominal CT-scan and punch biopsy, and she was subsequently treated as a CUP-syndrome case. The final pathologic report showed the evidence of an ectopic breast tissue cancer. Conclusion: Despite the rarity of this condition, physicians should always keep in mind the possibility of ectopic BC in order to make an early diagnosis and adequately treat these patients.

Experience of Ultrasound-Guided Vacuum-Assisted Excision of a Phyllodes Tumor Arising From Ectopic Axillary Breast Tissue: A Case Report

: An axillary breast is a common condition, which can cause various diseases arising from the breast tissue. Among these diseases, phyllodes tumors are very rare fibroepithelial tumors, which resemble fibroadenomas. Surgical removal is the treatment of choice for phyllodes tumors to prevent recurrence. Inpatient treatment and general anesthesia are required for surgical removal, and fibrosis, skin scarring, and neurological symptoms may occur after surgery. Ultrasound-guided vacuum-assisted excision, because of its advantages, is an alternative to surgical excision for clinically benign breast masses. Therefore, in cases of clinically benign or concordant benign lesions, following a core needle biopsy, ultrasound-guided vacuum-assisted excision can be considered with sufficient preoperative measures and close follow-up of the ectopic axillary breast.

Gynaecomastia-like hyperplasia of axillary ectopic breast tissue – a case report

Aim: To highlight the incidental finding of gynaecomastia-like hyperplasia of axillary ectopic breast tissue in a female patient, with review of the literature. Case report: A 36 year old multiparous female presented for surgical management of right axillary ectopic breast tissue on a background history of a previously excised right lower quadrant breast lesion one year prior that showed a 29mm grade 3 invasive breast carcinoma of no special type with triple negative immunophenotype. The sentinel nodes were uninvolved and excision margins were clear. She underwent neoadjuvant chemotherapy and local radiotherapy. There was no radiological or clinical evidence of recurrence at the one year mark. Excised axillary fibroadipose tissue histologically showed benign breast ducts without lobules demonstrating occasional micropapillary hyperplasia, as well as stromal pseudoangiomatous stromal hyperplasia (PASH). There was no evidence of in-situ or invasive malignancy. The overall appearance was that of gynaecomastia-like hyperplasia. Discussion: Gynaecomastia-like hyperplasia is a rare finding in breast specimens in female patients. It is exceedingly rare in ectopic breast tissue, with only a single case report in the literature to date. The spectrum of histologic changes are characteristic, although the pathogenesis is poorly understood due to the rare nature of this process.

Ectopic breast tissue carcinoma—a case report

Background: Ectopic breast cancer is a rare entity and an important diagnostic and treatment challenge. Case Presentation: 46-year-old female with previous history of resection of ectopic axillary breast tissue who was referred to our Institution after a second resection following an increase in left axillary volume. Histology reported a ductal ectopic breast tissue carcinoma that invaded the deep layer of the dermis and was positive for estrogen and progesterone receptors and Human Epidermal growth factor Receptor-type 2. After being referred to our Institution, surgical margin re-excision and sentinel node biopsy were performed. The patient initiated hormone therapy and underwent adjuvant radiotherapy to the breast and axilla (50 Gy/25 fractions, in daily 2 Gy fractions with a 3D conformal radiation therapy technique) and boost with bolus to the axilla (to complete 60 Gy). She remains in follow-up, with no recurrence to date. Conclusion: A high index of suspicion is required for the timely diagnosis of this rare condition. Since there are no specific guidelines, treatment remains a challenge.

Fibroadenoma of bilateral axillary ectopic breast tissue: A rare case report based on Orem’s Self Care theory

Introduction: Ectopic Breast Tissue (EBT) is still a condition seen as sporadic (2-5%), and it is often delayed and ignored due to lack of awareness, whereas it may be exposed to malignant diseases. it must be always kept in mind for differential diagnosis of an EBT. We think that this case report is important because EBT associated with fi bro-adenoma is a quiet rare condition.

Malignant Phyllodes Tumor in Ectopic Breast Tissue: A Case Report with a Literature Review

Supernumerary breasts come from ectopic breast tissue which regression was incomplete. Typically, it is a single supernumerary gland, located in the axilla. Ectopic breast tissue is subject to the same pathologic events that occur in normally positioned breasts. Excision may be required for diagnosis, treatment of symptoms or cosmesis. We report a case report of a female patient aged 22 years, without medical history. She consulted for a left axillary swelling. Breast ultrasound showed: Voluminous mass of axillary tail with polylobed contours, Aspect evoking a phyllodes tumor. The patient had a wide excision. Anapath review concluded: Malignant phyllodes tumor in ectopic breast tissue and absence of residual tumor. Abdominal ultrasound and chest x-ray were normal. Adjuvant systemic treatment and radiotherapy were not delivered. Our patient is regularly followed: She doesn’t develop distant metastases or loco-regional relapse. Axillary ectopic breast tissue may provide a diagnostic challenge, as other benign and malignant lesions occur in this area. Malignant Phyllodes tumor in ectopic breast tissue is an extremely rare occurrence. Wide breast surgery is the mainstay of the treatment of non-metastatic malignant phyllodes tumors of the breast.

Bilateral Ectopic Axillary Breast Tissue in an Adult Female

Accessory breast tissue is rare, affecting about 2-6% of the general population and it is usually bilateral. It is a benign lesion that indicates incomplete involution of the milk line during embryogenesis. Most of the defects appear where the embryonic milk-line was located, but cases have been reported of ectopic breast tissue in other parts of the body, including the face, scapula, limbs or buttocks. The first classification of congenital breast anomalies was published by Kajava in 1915, who ordered them in classes from I to VIII. Although this classification was later simplified, the original continues to be that most used. The case is described here of a 42-year-old woman who presented with bilateral axillary lumps which had recently increased in size. Ultrasonography (US) and mammogram suggested ectopic breast tissue and the masses were surgically removed. Histopathological examination of the specimen confirmed the initial diagnosis of ectopic breast tissue. Because of the benign nature of the lesion, no further treatment was needed, but 3 and 6-month and annual follow-up was suggested.

Giant Axillary Fibroadenoma: A Rare Case Report

Axillary ectopic breast tissue occurs commonly in women The fibroadenoma is commonest benign tumour of the normal female breast But fibroadenoma occurring in axillary ectopic breast tissue is of rare occurrence The giant fibroadenoma are very rare in axillary ectopic breast tissue This case is being reported having a giant fibroadenoma of x cm in right axilla in years female The clinical history did not give any clue to presence of ectopic breast tissue in axilla Excision biopsy confirmed the diagnosis of fibroadenoma This case is being reported as giant fibroadenoma of such a large size occurring in axilla for its rarity nbsp

Fibroadenoma of ectopic breast tissue of the axilla in an adolescent girl

Ectopic breast tissue (EBT) is a well-described entity in the English literature. However, fibroadenoma of the ectopic breast is a rare entity. We present a case of a 13-year-old adolescent girl with a subcutaneous mass in the right axilla that was pathologically identical to fibroadenoma seen in the EBT. To our knowledge, this is the second youngest patient reported with axillary EBT, which should be considered as a part of the differential diagnosis for axillary masses.

A Nonpalpable Nodule in Ectopic Axillary Breast Tissue: Consider Phyllodes Tumor

Benign and malignant pathology can develop in ectopic axillary breast tissue, such as fibroadenomas, phyllodes tumors, and breast cancer. We present a rare case of an asymptomatic 43-year-old woman with an axillary nodule which was identified during screening mammography within ectopic axillary breast tissue, initially considered as a suspicious lymph node. Radiologic studies were considered as Breast Imaging-Reporting Data System (BI-RADS) 4. A hyperdense, lobular, and well-circumscribed nodule was identified in mammogram while the nodule by ultrasound (US) was hypoechoic with indistinct microlobular margins, without vascularity by Doppler, and measuring 1.26 × 1 cm. Core-needle biopsy reported a fibroepithelial neoplasm. The patient was submitted to local wide-needle excision located in intraoperative radiography of the surgical specimen and margin evaluation. Final histopathological study reported a 1.8 × 1.2 cm benign phyllodes tumor, with irregular, pushing, and clear wide margins within normal ectopic breast tissue. The patient without surgical complications continued annual screening without recurrence during a follow-up that took place 24 months later.
