Primary carcinoma of ectopic breast tissue

We describe a case of a 37-year-old woman with a left axillary mass. Often, the initial differential diagnosis of an axillary mass is not easy to make. We performed fine-needle aspiration of the axillary mass that revealed the presence of numerous epithelial neoplastic cells. A bilateral digital mammography, chest and abdomen computed tomography scan, and a magnetic resonance imaging scan (MRI) of the axillary region were performed. In our case, the MRI was able to exclude the presence of neoplastic tissue in the breast; moreover, it confirmed the presence of metastatic lymph nodes and recognized a second type of nodular lesion in the axilla, showing on the MRI a radiologic pattern similar to breast tissue.     

A case of ectopic breast cancer with a literature review

A 63-year-old woman was referred to our hospital because of a right axillary nodule in 2004. Physical examination showed a spherical nodule measuring 0.5 cm in diameter in the right axilla. No mass was palpable in either breast. Mammograms were normal. Ultrasonography revealed a subcutaneous hypoechoic mass 0.7 mm in maximum diameter in the right axilla. The patient underwent an excisional biopsy. Histological examination revealed an invasive ductal carcinoma (scirrhous carcinoma) in ectopic breast tissue. The patient subsequently underwent a wide local excision of the tissue surrounding the biopsy scar, with axillary lymph node dissection. Histologically, no residual tumor or nodal metastasis was found. Postoperatively, she received endocrine therapy and remains well, without any evidence of recurrence 4 years 10 months after operation. Cancer of the ectopic breast tissue is rare, and most cases present as a solitary axillary mass. Long-term outcomes remain unclear. We present a case of breast carcinoma in the axillary ectopic mammary gland and summarize the clinical features of 94 cases, including ours, in Japan. We also compare long-term survival between ectopic breast cancer and usual breast cancer according to TNM T stage and lymph node metastasis.     

Role and extent of lymphadenectomy for early breast cancer.

A better understanding of the locoregional and systemic approaches to breast cancer over the past decade and one-half has altered the perspective on surgical management of the axilla. An increased awareness of the importance of early diagnosis and appropriate staging has focused further attention on the extent of resection of axillary lymph nodes. Examined here are the anatomy and physiology of the axillary lymph nodes, their clinical evaluation, the significance of histologic evaluation, a discussion of the procedure's role in staging and therapy, and a presentation of the complications of axillary lymph node dissection. It is in this light that we discuss the extent of axillary lymphadenectomy in early diagnosis of breast cancer.     

Primary infiltrating ductal carcinoma arising in aberrant breast tissue of the axilla: a rare entity. Report of a case

A 52-year-old woman presented with a palpable nodule in the right axilla. Physical examination revealed a 2.5 x 2.5 cm, nontender, firm, brownish, and peripherally hyperemic mass with overlying skin retraction on the right anterior axillary fold. Bilateral mammogram was negative. Ultrasonography of the right axillary region showed a 1.8 x 1.1 cm, poorly defined hypoechoic mass with irregular margins and posterior acoustic shadowing. Fine-needle aspiration biopsy of the mass revealed malignant epithelial cells. The patient underwent a wide local excision of the right axillary lesion with en bloc axillary lymph node dissection. Histopathological examination revealed an infiltrating ductal carcinoma. Here we report this case of carcinoma originating from aberrant breast tissue in the axilla. It is suggested that subcutaneous lesions of uncertain origin around the periphery of the breast should be suspected for breast carcinoma and treated appropriately.     

Individualizing Axillary Management in Breast Cancer Treatment

Management of the axilla in patients with breast cancer has evolved significantly in the last century. The status of the axillary lymph nodes continues to provide important prognostic information. However, in contrast to the beliefs of Halsted, we now understand that surgical clearance of the axilla is not critical to long-term survival. Indeed, tumor biology and occult systemic metastases determine long-term survival after breast cancer treatment. Randomized controlled trials have demonstrated the safety and efficacy of sentinel lymph node biopsy in patients with early breast cancer and without clinical evidence of axillary involvement. Management of the axilla should be tailored to the individual patient’s clinical stage, patient and tumor characteristics, and treatment preferences. Special consideration should be given to the following situations: elderly patients, pregnancy, treatment of DCIS, prior axillary surgery, prophylactic mastectomy, inflammatory breast cancer, and neoadjuvant chemotherapy. Management of the axilla will continue to change as additional evidence from randomized controlled trials becomes available.     

Tuberculosis of axillary lymph nodes with primary breast cancer

A rare case of tuberculosis of axillary lymph nodes occurring with primary breast cancer is presented. A 78-year-old woman with no history of pulmonary tuberculosis was admitted to our hospital to undergo examination for a lump in her right breast. The tumor was in the upper outer quadrant of the right breast. On palpation, the tumor was 1.2 cm in diameter and axillary lymph node swelling was noted. Mammography disclosed a spiculated mass and swelling and calcification of the axillary lymph nodes. Sonography showed an irregular hypoechoic mass in the right breast and lymph node swelling in the right axilla, indicating breast cancer with axillary lymph nodes metastases. Chest X-ray showed clustered calcifications in the right axilla and a granular shadow in the right upper lobe. Breast conserving therapy was carried out. Invasive papillotubular carcinoma of the right breast and granulomas with calcification of lymph nodes, compatible with tuberculosis, was diagnosed. Tubercle bacillis were detected by culture of lymph nodes. This case suggests that X-ray is useful for diagnosing lymph node tuberculosis. Lymph node tuberculosis should be suspected when lymph node swelling is noted and X-ray shows clustered calcifications in axillary lymph nodes.

A case of occult breast carcinoma with irradiation therapy and axillary lymph node dissection

A 78-year-old woman was seen at the hospital for a swollen left axillary node. There was an elastic hard mass measuring 0.7 cm in diameter in the left axilla, but no breast mass was palpable in the bilateral breasts. Mammography did not reveal any tumor and calcification, and there was no abnormalities on breast ultrasonography (US), computed tomography (CT) and magnetic resonance imaging (MRI). Aspiration biopsy cytology of the left axillary node revealed adenocarcinoma. Systemic examination failed to reveal primary lesion. Thus, to make the diagnosis, we enucleated the axillary nodule. Immunohistochemical staining for the excisional specimen revealed an estrogen receptor, progesterone receptor and gross cystic disease fluid protein-15 (GCDFP-15) was strongly positive, so we diagnosed it as an occult breast carcinoma. After obtaining her informed consent, the patient underwent left axillary lymph node dissection and irradiation therapy of the left breast. The patient has been disease-free under adjuvant chemoendocrine therapy. We treated the occult breast carcinoma with radiation therapy of the breast and axillary lymph node dissection, and provided a review of the literature.     

Phyllodes tumor arising in ectopic breast tissue of the axilla

We examined a 31-year-old woman with a solid mass in her left axilla. Physical examination and ultrasonography confirmed a 2 cm well-defined mass. Fine needle aspiration biopsy suggested fibroadenoma of breast. Excisional biopsy revealed benign phyllodes tumor of the ectopic breast tissue. Phyllodes tumor in ectopic breast tissue is an extremely rare occurrence. Only nine cases have been reported, including tumors of the vulva, inguinal region and axilla. This is the second case in the axillary region.     

Predictors of arm morbidity following breast cancer surgery

Objective: Arm morbidity post‐breast cancer surgery is increasingly being recognized as a chronic problem for some women following breast cancer surgery. The purpose of this study was to examine demographic, disease, and treatment‐related predictors of a comprehensive array of chronic arm morbidity (pain, lymphedema, functional disability, and range of motion) post‐breast cancer surgery. Methods: Women (n=316) with a non‐metastatic primary diagnosis of breast cancer were accrued from cancer centers in four Canadian cities. Patients completed a clinical assessment and measures of arm morbidity at 6–12 months post‐breast cancer surgery. The independent variables in the MANOVA to predict arm morbidity included: Lymph node management type, number of axillary nodes dissected, type of surgery, disease stage, presence of post‐operative infection, radiation to the axilla, body mass index (BMI), assessment time post‐surgery, education, and partner status. Results: Pain was significantly predicted by axillary lymph node management, lack of a partner, and post‐operative infection; lymphedema by axillary lymph node management, number of axillary nodes dissected, radiation to the axilla, and having a modified radical mastectomy; functional disability by post‐operative infection and high BMI; and restricted external rotation by axillary lymph node management, low educational attainment, and advanced disease. Conclusion: Comprehensive behavioral management and rehabilitation programs are needed to treat arm morbidity following breast cancer surgery. These programs should address the full scope of symptoms and associated psychosocial and functional sequelae. Copyright © 2010 John Wiley & Sons, Ltd.     

New concepts in axillary management of breast cancer

In the last decades, surgical treatment of breast cancer has evolved from more extensive procedures like radical mastectomy to less invasive breast conserving surgery. Similarly, surgical management of axilla has enormously changed from routine axillary dissection to sentinel lymph node biopsy. Traditional surgical approach to the axilla in case of sentinel lymph node negativity is to avoid completion axillary dissection. However, surgeons even avoid performing axillary dissection in selected patients with positive sentinel lymph node in clinical practice depending on the recent randomized controlled studies supporting this concept. All of the recent changes in the management of positive axilla necessitate surgeons to refresh their knowledge on this challenging topic.     

Extraskeletal osteosarcoma in the axilla associated with breast carcinoma.

A case of extraskeletal osteosarcoma arising in the axilla in a 77-year-old woman is described. Because of its association with an ipsilateral breast carcinoma, the axillary mass was at first assumed to be a lymph node with metastatic breast carcinoma. The occurrence of extraskeletal osteosarcoma in the axillary is rare and association with breast carcinoma has never, to our knowledge, been described.     

Determination of axillary nodal status in surgery of breast carcinoma: A prospective study of thirty-five patients

Thirty-seven axillary status of patients with breast carcinoma was studied with preoperative and peroperative palpation before mastectomy and total axillary dissection. Special attention was paid to the clinical supiciousness and size of axillary nodes. The preoperative axillary palpation gave false diagnosis of axillary content 27% of the time and peroperative, 19%. Of all 249 nodes studied, 54 were found to contain malignant growth in routine histological examination. Mean diameter of malignant nodes was 12.4 mm and of benign nodes, 6.3 mm. The most clinically suspect axillary lymph node gave correct diagnosis of axillary status in 72 % of the cases. The 2 most suspect lymph nodes together were positive in 89%. There was no case with histologically positive axilla where none of the 3 most suspect lymph nodes was malignant. We conclude that at least the 3 most suspect axillary lymph nodes must be removed for histological examination to be sure that axillary metastasizing of breast carcinoma can be found by routine histological examination.     

Positive and negative aspects of sentinel lymph node biopsy in breast cancer

The sentinel lymph node (SLN) is the first lymph node to receive lymphatic drainage from a tumor. SLN biopsy has become a mainstay of breast cancer management and is used when the axilla is clinically clear of disease. Staging of the axilla in breast cancer is used to predict prognosis and in planning adjuvant treatment. SLN biopsy is not used where there has been previous axillary or breast radiotherapy or surgery, locally advanced or inflammatory disease and stage IV disease. Controversies remain in several specific clinical situations, including management of the axilla following detection of a positive SLN. There are no sufficiently robust predictive tumor features to prevent completion axillary dissection in these cases. However, there is evidence that immediate axillary surgery for operable, clinically node-negative breast cancer provides no survival benefit and may be unnecessary for many women. SLN biopsy may have a role after neoadjuvant chemotherapy, sparing some women from axillary node dissection. Further work is required to ascertain SLN biopsy sensitivity prior to its routine use in the clinic for multicentric and multifocal disease.     

Axillary metastasis as first symptom of occult breast cancer: a case report

Axillary lymph node metastasis from an occult breast carcinoma is a rare occurrence. We report this condition in a 59-year-old woman who presented with a swelling in the right axilla. No breast mass was clinically evident. Mammography, ultrasonography and multiple random fine-needle breast biopsies yielded no pathological findings. No extramammary primary lesions were present. Axillary sampling was performed and histological examination revealed the presence of metastatic adenocarcinoma in three of the 12 dissected lymph nodes. Estrogen receptors were positive and immunohistochemistry pointed to a breast origin. All these data were suggestive of occult breast cancer. The patient refused any further treatment but accepted clinical and radiological follow-up. Eight years later mammography revealed in the same breast a 10-mm nodule containing microcalcifications, which was not evident at physical examination. The patient underwent a lumpectomy. Intraoperative histology was positive for breast carcinoma and complete axillary clearance was performed. Histological examination revealed a lobular invasive breast carcinoma and the presence of micrometastasis in one of the 23 removed lymph nodes. The patient was given radiotherapy to the breast and axilla and tamoxifen. At present, one year after the appearance of the primary tumor, she is free of disease. Based on this case report we suggest an eclectic approach in the management of patients with axillary metastasis from occult breast cancer, depending on the clinical, pathological and biological findings.     

Conservation of the axilla: an audit of sentinel lymph node biopsy after a new start

Background

Four hundred twenty-eight patients with a diagnosis of breast cancer were assessed. All patients underwent axillary ultrasonographic scanning preoperatively or at the time of initial breast imaging. Suspicious axillary glands underwent core needle biopsy under ultrasonographic guidance.

Patients and Methods

The majority of patients were in the age range of 40 to 80 years. Sentinel lymph node biopsy (SLNB) was performed in 360 patients.

Results

Sixty-eight patients had axillary clearance as a first axillary procedure. Of these patients, 55 had a preoperative diagnosis of a positive axillary gland in the axilla on ultrasonographically guided core needle biopsy, and 13 had clinically palpable axillary lymph glands. Seventy-one patients (21%) had a positive sentinel lymph node on histopathologic examination after hematoxylin and eosin (H & E) staining. Preoperative scans of the axilla had been reported as normal in these patients. In 68 patients, further axillary surgery was performed to clear the axilla; 24 of these patients (35%) had more positive glands in the axilla. In 44 patients (65%) the sentinel lymph glands were the only positive glands. Of 224 patients with a tumor size ≤ 20 mm, there were 30 patients (14%) who had a positive sentinel node. Of 136 patients with a tumor size > 20 mm, there were 41 patients (33%) with positive sentinel nodes.

Conclusions

Sentinel lymph node biopsy in breast cancer allowed conservation of the axilla in 80% (289/360) of patients with negative sentinel lymph nodes in this study. Preoperative ultrasonographically guided core needle biopsy reduced the need for a second operation in 55 patients (13%).     

Lack of efficacy of xeroradiography to preoperatively detect axillary lymph node metastases in breast cancer

Xeroradiography of the axilla was performed in 132 patients with operable breast cancer to investigate the status of the axillary lymph nodes. Pathologic findings were correlated with the results of clinical examination and xeroradiographic findings. Xeroradiography does not appear to have improved our ability to identify axillary lymph node metastases in patients with breast cancer.     

Ultrasonography of the axilla in the follow-up of breast cancer patients who have a negative sentinel node biopsy and who avoid axillary clearance

The clinical value of ultrasonography of the axilla in detection of breast cancer recurrence is not known among patients who have a negative sentinel node biopsy and avoid axillary clearance. We studied a cohort of 205 such patients using ultrasonography one and three years after breast surgery. A recurrent tumour was found in the axilla in only two (0.5%) of the total of 383 ultrasound examinations performed during the study, and only one (0.3%) of the 369 examinations performed at the scheduled study visits revealed cancer. None of the ultrasound examinations was false positive, and no study participant was subjected to unnecessary surgery due to ultrasound monitoring. We conclude that the rate of breast cancer recurrence in the ipsilateral axilla is low following sparing of the axillary contents, and that monitoring of such patients with repeated ultrasound examinations is unlikely to be cost-effective.     

Coexistence of breast cancer and tuberculosis in axillary lymph nodes: a case report and literature review

Coexistence of breast cancer and tuberculosis (TB) of the breast and/or axillary lymph nodes is uncommon. In this article, we present a case of tuberculous axillary lymphadenitis existing simultaneously with invasive ductal carcinoma of the left breast. We also conducted an extensive literature review of English language studies published on the coexistence of breast cancer and TB of the breast and/or axillary lymph nodes from 1899 to 2011 using the PubMed and Google Scholar databases. Twenty-nine cases of coexisting breast cancer and TB of the breast and/or axillary lymph nodes have been published to date, including a 74-year-old female diagnosed with left breast cancer and TB of the axillary lymph nodes. A tumor in the right breast was detected in 14 patients and in the left breast in 12 patients between the ages of 28 and 81 years, but no data were available regarding the side on which the tumor occurred in three patients. Eighteen patients underwent a modified radical mastectomy, five patients underwent a radical mastectomy, two a lumpectomy and an axillary lymph node dissection (ANLD), two a quadrantectomy (Q) and an ALND, and two an applied excision. TB was detected at the axilla in all 21 patients in patients with no TB of the breast, and TB was also detected in the axilla in five of eight patients with breast TB. Both a tumor and TB lymphadenitis were detected following an axillary dissection in 14 patients, and both cancer metastasis and TB lymphadenitis were detected at the same lymph nodes in six of these patients. The simultaneous occurrence of these two major illnesses in the breast and/or axillary lymph nodes can produce many problems with respect to diagnosis and treatment. Accurate diagnoses are necessary for down-staging carcinoma of the breast and for identifying curable disease.
