Axillary Ectopic Breast Tissue Research Articles

Axillary Masse, is it an Ectopic Mammary Gland?

Ectopic breast tissue or super numerary mammary gland is a congenital condition characterized by the development of mammary tissue along the embryonic milk line. This condition Occurs in 0.4-6% of the general population. The most common site of development of super numerary mammary gland is the axillar region. Axillary ectopic breast tissue may provide a diagnostic challenge, as other benign and malignant lesions occur in this area. We report a case of 18 years-old girl presenting an axillary masse considered firstly as an ectopic mammary gland. Ultrasound aspect and axillary MRI correct the diagnosis and lead to provide specific management of this tumor.

Primary adenoid cystic carcinoma of axillary ectopic breast tissue: Case report of a rare entity

Ectopic breast tissue, a developmental anomaly, is a rare occurrence. Isolated pathologies in ectopic breast tissue with normal breast architecture are even rarer. Cases with primary invasive ductal carcinoma, invasive lobular carcinoma, secretory carcinoma, and mucinous carcinoma have been reported in ectopic breast tissue. We report a case of primary adenoid cystic carcinoma of axillary ectopic breast tissue, which to our belief has never been reported earlier.

A Rare Finding of Coexisting Fibroadenoma and Duct Ectasia in Axillary Ectopic Breast Tissue

Ectopic breast tissue (EBT) can present anywhere along the milk line from axilla to groin. It can harbor all the pathological conditions as that of the normal breast though incidence is very low. Fibroadenoma is rare in accessory breast and only a few cases have been reported in the literature. Here, we report a 30-year-old female presented with a firm and freely mobile right axillary lump measuring 6 cm × 4 cm. Fine-needle aspiration cytology revealed it as accessory breast tissue. However, the excision biopsy of the same showed fibroadenoma along with duct ectasia in EBT. This case has been reported due to its rarity and for consideration of fibroadenoma in differential diagnoses of axillary swellings.

Fibroadenoma of the Ectopic Axillary Breast Tissue: Sonographic Appearances

Ectopic breast tissue is reported to occur in 0.4% - 6% of women. Breast neoplasms may develop in ectopic breast tissue, as in eutopic breast tissue. The most frequent condition in ectopic breast is breast cancer. Fibroadenomas of ectopic breast tissue have been reported, but are rare. We report two cases of fibroadenomas of ectopic axillary breast tissues. The sonographic appearance of the nodules was spherical and hypoechoic. We found the component of breast tissue near the nodule. It is important to diagnose fibroadenomas of ectopic breast tissue before a histologic examination.

Fibroadenoma of axillary ectopic breast tissue: A rare clinical entity

Supernumerary breast or polymastia is a well-documented anomaly of the breast and commonly presents along the embryonic milk line extending between the axilla and groin. Reported incidence of accessory breast is 0.4-6% in females. During 2 years period, we encountered only two cases out of twenty cases of axillary lumps. We present one case of fibroadenoma in ectopic breast tissue (EBT) in axilla. Ectopic breast denotes breast tissue at more than two pectoral regions, which is mostly benign but at times can be malignant. EBT is at a greater risk of malignancy. Fibroadenoma of ectopic axillary breast tissue (EBT) is quiet rare, but should always be kept in mind for differential diagnosis of an axillary mass.

Gastric metastasis of ectopic breast cancer mimicking axillary metastasis of primary gastric cancer.

Ectopic breast tissue has the ability to undergo all the pathological changes of the normal breast, including breast cancer. Gastrointestinal metastasis of breast cancer is rarely observed and it is very difficult to differentiate gastric metastases from primary gastric cancer. We present a case of 52-year-old female, who suffered from abdominal pain. Physical examination showed a palpable mass in the left anterior axilla and computerized tomography revealed gastric wall thickening with linitis plastica. When gastroscopic biopsy showed no signs of malignancy, excisional biopsy was performed in the left axilla. Histological examination revealed invasive lobular carcinoma of the breast, consistent with ectopic breast cancer. Further gastroscopic submucosal biopsies and immunohistochemical studies revealed gastric metastases of invasive lobular carcinoma. Axillary ectopic breast tissue carcinomas can mimic axillary lymphadenopathies. Additionally, gastric metastasis of breast cancer is an uncommon but possible condition. To the best of our knowledge, this is the first report of ectopic breast cancer with gastric metastasis.

Lobular ectopic breast carcinoma: A case-report

In about 1–2% of the population an incomplete regression of the embryonic mammary line occurs, which may result in the presence of ectopic breast tissue. An ectopic breast tissue carcinoma is a rare entity. The authors present a case-report of a 51-year-old female patient, with a lobular carcinoma in an axillary ectopic breast tissue submitted to surgery and adjuvant radiotherapy.

Male breast cancer arising in ectopic axillary breast tissue: A diagnostic dilemma

Male breast cancer arising in ectopic axillary breast tissue is a rare occurrence and few cases have been reported in the literature. Due to its rarity, male axillary breast cancer is easy to misdiagnose. As for adenocarcinoma in the axilla, it is difficult to identify whether the origin is the mammary tissue or the skin appendages, particularly in cases where there is a poor differentiation. The present study reports the case of a male patient with a right axillary lesion that had been present for 6 months. A histological evaluation revealed the features of a poorly-differentiated adenocarcinoma with regards to the pathological report. The patient was diagnosed with a metastatic adenocarcinoma with unknown primary origin. However, following 4 cycles of intensive chemotherapy, the patient experienced bone metastasis while the local lesion was in partial remission. Further immunohistochemistry confirmed its mammary origin. There is limited literature relating to male ectopic axillary breast cancer, and a high probability of misdiagnosis of this disease.

Gynecomastia-Like Hyperplasia of Axillary Ectopic Breast Tissue in a Young Female

Gynecomastia-like hyperplasia of orthotopic female breast tissue is a rare entity. We present the singularly unique case of a 22-year-old female who presented with a small axillary mass subsequently discovered to be a discrete deposit of ectopic breast tissue with gynecomastia-like hyperplasia. This case highlights the etiology, variable presentation, and evaluation of ectopic breast tissue.

MRI Appearance Of Ectopic Axillary Breast Tissue During Lactational Period

Popülasyonun %1-5’inde aksesuar meme dokusuna rastlanmaktadır. Otuzbir yașında bir kadın hasta postpartum dönemde ağrılı aksiller kitle ile bașvurdu. Rutin MRG sekanslarında aksillada normal meme parankim dokusu ile benzer özellik gösteren ancak ayrı olarak izlenen sinyal değișiklikleri belirlendi. Aksiller kitlelerde benign durumların malign lezyonlardan ayrılması gereksiz girișimlerden kaçınılması açısından önem tașımaktadır. MRG özellikle peripubertal-pubertal kız çocuklarında ve genç hastalarda aksesuar meme dokusu tanısında değerli bir modalite olarak bildirilmektedir

Bilateral axillary ectopic breast tissue

A 14-year-old girl presented with progressively growing bilateral painful axillary tumours (fi gure A). Histopathology showed slightly hyperplastic glandular tissue without cytological atypia within the reticular dermis and fatty tissue (fi gure B). The glandular epithelium stained positive for oestrogen and progesterone receptors (fi gure C), which led to the diagnosis of ectopic breast tissue. An MRI scan showed extensive axillary breast tissue without connection to the eutopic breasts (fi gure D). Ectopic breast tissue occurs in 2–6%

Bilateral axillary ectopic breast tissue

Summary Ectopic breast tissue is a developmental anomaly which may occur anywhere along the milk line through the axilla to the inguinal region. Although ectopic breast tissue is often asemptomatic , it may cause cosmetic complaints. As benign and malignant breast diseases may develop within this tissue, it is very necessary to be careful. Here, a 48year- old female patient with bilateral axillary ectopic breast tissue is presented. Ectopic breast tissue should be considered in the differential diagnosis of patients with axillary mass.

Primary carcinoma of ectopic axillary breast tissue

The presence of ectopic breast tissue is reported in 2-6% of the general population with most cases being located in the axillary region. Although the same pathology occurs in both eutopic and ectopic breast tissue, primary carcinoma of ectopic breast tissue has been reported only in a small number of cases. Because an overlying accessory areola or nipple is often missing and because of a general lack of awareness among physicians and patients concerning these unsuspicious nodules, clinical diagnosis is frequently delayed. Histological diagnosis can also be delayed if ectopic breast tissue is not present or screened for in the biopsy specimens as apocrine glands of the breast and skin, respectively, exhibit striking similarities and immunohistochemistry is of limited help. Diagnostic delay is demonstrated by the case of a 56-year-old patient who underwent a series of four surgical excisions of a primary ectopic breast carcinoma and developed local lymph node metastasis until treatment with tamoxifen was started. As two-thirds of reported cases of primary ectopic breast carcinoma arose within the axillae, this case underlines the importance of a search for ectopic breast tissue in the context of axillary ductal carcinoma.

Sonographic appearance of a carcinoma developed in ectopic axillary breast tissue

Primary breast cancer of ectopic axillary breast tissue is almost never diagnosed preoperatively. When not accompanied by nipple-areolar complex, the mass is often believed to be a lipoma, an enlarged lymph node, or a skin lesion such as a sebaceous cyst or hydradenitis suppurativa. When an axillary mass is found, a percutaneous needle biopsy is mandatory to rule out the diagnosis of cancer in ectopic breast tissue. We describe the sonographic findings of a case of ductal carcinoma in axillary ectopic breast tissue.

Lobular Carcinoma in Ectopic Axillary Breast Tissue

Accessory mammary tissue is reported to occur in 2 per cent to 6 per cent of women and results from failure of regression of a portion of the galactic band, which runs from the axilla to the groin during embryogenesis. The differential diagnosis of a mass located along the course of the primitive milk line must include accessory breast tissue. This tissue is subject to the same physiologic and pathologic changes as in the breast proper. There are numerous case reports of masses arising in accessory breast tissue ranging from fibroadenomas and phyllodes tumors to invasive mucinous adenocarcinoma. The predominant pathology, as with the pectoral breast, is that of invasive ductal carcinoma. We present the case of a lobular carcinoma arising in axillary ectopic breast tissue. Although this has previously been reported, it is a rare entity.

Axillary breast tissue mistaken for suppurative hidradenitis: an avoidable error

The differential diagnosis for a solitary axillary mass is extensive. Based on the initial history and physical examination of the patient presented in this case report, the diagnosis of suppurative hidradenitis was incorrectly reached. This subjected her to a surgical procedure that was not indicated for the actual diagnosis of ectopic axillary breast tissue. This article reviews the workup for a solitary axillary mass and discusses multiple aspects of ectopic breast tissue.

Breast-feeding With Ectopic Axillary Breast Tissue

Axillary breast tissue, which may be an extension of the tail of Spence, is a normal variant that has been reported in the literature relatively infrequently, although it may be present in a number of asymptomatic women. If axillary breast tissue becomes symptomatic, this usually occurs during pregnancy or immediately postpartum when a woman begins breast-feeding. Symptoms are swelling and pain due to engorgement. A literature review revealed that management is generally conservative, with cessation of breast-feeding to allow regression of the tissue. This report describes a woman who successfully pumped her axillary breasts to relieve pain and engorgement; this allowed her to continue breast-feeding for several weeks. Axillary breast tissue should be monitored for pathologic change.
