Primary angiosarcoma of breast: A case report

A rare case report of breast sarcoma and synchronous thymoma in a 60-year-old woman

This case report aims to describe the clinical presentation, imaging findings, histopathological features and therapeutic approach of a patient diagnosed with coexisting breast sarcoma and thymoma. A 64-year-old woman presented with a palpable lump in her left breast, and subsequent imaging studies (ultrasound, mammography, and MRI) revealed breast sarcoma, a rare and aggressive subtype of breast cancer. At the same time, the MRI revealed the presence of a thymoma. A multidisciplinary approach involving surgeon, breast specialist and oncologist is essential for optimal management and favorable outcomes in patients with this rare diagnosis.

Primary angiosarcoma of breast in an octogenarian woman: A case report with literature review

INTRODUCTION AND IMPORTANCE

Primary breast angiosarcomas are endothelial derived breast sarcomas found in younger to middle age groups. The diagnosis of primary breast angiosarcoma in an octogenarian woman is a rare incidence.

CASE PRESENTATION

We report a case of 87-year-old postmenopausal woman presenting with history of lump in her right breast for four months. Ultrasound guided biopsy was performed which confirmed the diagnosis of angiosarcoma hence, subjected to simple mastectomy. She was doing quite well for one year when ultimately, she developed metastatic disease and couldn't survive more.

CLINICAL DISCUSSION

Microscopically, these tumours are classified into grades I, II and III. Hematogenous route has been taken for metastasis having lungs being most involved. There are limited case reports and studies that have investigated the use of adjuvant radio/chemotherapy.

CONCLUSION

Primary angiosarcoma of breast is a rare disease in old age group with limited treatment options which resulted in poor prognosis and early relapse.

R, Dewangan M, Issar AK. Primary Angiosarcoma of the Breast: A Rare Case Report in Postmenopausal Women

Primary angiosarcoma (PAS) of the breast is a rare malignant tumor arising from endothelial cells lining the blood vessel and accounts for 0.04% of all breast tumors. It occurs predominantly in young patients usually presenting as nonspecific imaging features and is often overlooked and misdiagnosed at radiology and pathology. Angiosarcoma prognosis is generally poor; however, surgery followed by adjuvant chemotherapy and radiotherapy improves the prognosis. We report a rare case of PAS in a 65-year-old postmenopausal woman. She was diagnosed with PAS based on typical clinical, mammography, ultrasound, and magnetic resonance imaging (MRI) features followed by core biopsy of the lesion. Our case had the unique features of enlarged vessels within and surrounding the lesion in mammography, as well as in MRI, which could be very helpful for future diagnosis of this rare PAS in postmenopausal women.

A rare presentation of pregnancy associated primary angiosarcoma of the breasts

Primary angiosarcoma of the breast is a rare malignancy that is important for radiologists to recognize in young patients because its imaging appearance may mimic benign lesions resulting in advanced stages of disease and overall decreased patient survival. We present a unique case of a bilateral primary angiosarcoma in a pregnant patient in her twenties. She presented with a self-detected, rapidly enlarging, non-tender right breast mass while in her third trimester.

Metastasis of primary breast angiosarcoma to axillary and supraclavicular lymph nodes: a rare case diagnosed using imaging data

Primary breast angiosarcoma (PBA) is a rare malignant tumor. PBA usually undergoes hematogenous metastasis; lymph node metastasis is very rare in such patients, and metastasis of PBA to the supraclavicular lymph nodes has not previously been reported. Here, we describe a rare case of PBA manifested by a diffuse enlargement of the left breast, with metastasis to the left axillary and bilateral supraclavicular lymph nodes. Contrast-enhanced ultrasound and positron emission tomography findings indicated a malignant lesion, whereas magnetic resonance imaging suggested a benign lesion. Core needle biopsy identified the lesion as a lymphangioma, and the histological characteristics suggested a high-grade angiosarcoma. Multimodal imaging and perfusion patterns obtained using various contrast agents can thus help to diagnose PBA.

Primary breast angiosarcoma resembling a common benign tumor: A case report

Introduction and importance

The breast angiosarcoma is a rare malignant vascular neoplasm; it represents nearly 0.05% of all breast cancers. Clinically, it could look like a haemangioma or pseudoangiomatous hyperplasia. Here, we report a case of a primary angiosarcoma of the breast (PAB) that mimics a giant fibroadenoma in physical examination and ultrasound features.

Case presentation

A 22 year-old woman came to our hospital complaining of a mobile non-tender mass in her right breast. It was monitored for a while until it became an 8 × 7 cm². Past medical and family histories were unremarkable. Ultrasonography showed a well circumscribed hypoechoic lobular mass. The wide excision was performed and the pathological study showed angiosarcoma. The patient was re-operated for total mastectomy, screened for distant Metastases and followed-up closely for one year.

Clinical discussion

Fibroadenoma-like lesions are not uncommon and physicians should pay an attention for any breast mass even in the patient who is young and has no risk factors of the traditional breast cancer. PAB is used to be missed in the clinical practice over the world; it is extremely rare and is proved by Immunohistochemistry. The full management could be totally completed by a mastectomy with/out axillary node dissection.

Conclusion

The primary angisarcoma of the breast (PAB) could resemble a fibroadenoma in pre-operative investigations. In many reviews, PAB mimicked many diseases. Thus, the medical literature needs more case reports and series to identify an ideal protocol of diagnosis and management.

Magnetic resonance imaging and contrast-enhanced ultrasound findings of a recurrent primary breast angiosarcoma: A case report

RATIONALE

Primary breast angiosarcoma (PBA) is a rare and overly aggressive entity and account for less than 1% of all breast cancer cases. PBA had a high rate of delayed preoperative diagnosis due to absent distinctive radiographic characteristics.

PATIENT CONCERNS

We report a case of a 47-year-old female patient who had a previous history of luminal cancer in the right breast with mastectomy; the patient complained of asymmetrically diffuse enlarged, accompanying with a painless mass in the left breast 12 years after the mastectomy of her right breast.

DIAGNOSES

The tumor mimicked idiopathic granulomatous mastitis on magnetic resonance imaging (MRI) at the first presentation. Contrast-enhanced ultrasound (CEUS) was performed for further lesion characterization and showed heterogeneous rapid hyper enhanced. An ultrasound-guided core needle biopsy was performed, and the pathology report indicated a breast angiosarcoma.

INTERVENTIONS

The patient underwent a nipple-sparing simple mastectomy with immediate reconstruction of the left breast.

OUTCOMES

After 8 months later, the tumor recurred, CEUS and MRI examination suggested PBA recurrence, then re-excision with implant removal was performed, the patient had a lung metastasis 4 months later eventually died 22 months after diagnosis.

LESSONS

It is not easy to diagnose PBA with the radiographic examination. This case's importance is by combining CEUS and MRI to reflect enhanced morphology and hemodynamic characteristics of PBA and help diagnose breast angiosarcomas.

A Case Report of Primary Breast Angiosarcoma: Clinical Presentation and Outcome After Adjuvant Radiotherapy

Angiosarcomas of the breast are infrequent subtypes of sarcoma that are often diagnosed after radiation therapy for primary breast cancer. Primary angiosarcomas (PAS) are rare tumors that constitute 0.04% of all malignant breast tumors. We report a case of a 40-year-old woman with a lump in the right breast and diagnosed as angiosarcoma by pathological evaluation. She underwent simple mastectomy followed by adjuvant radiation. She is alive and disease-free for 66 months although tumor size was large and one surgical margin was tumor positive. Breast angiosarcoma is often in advanced stage at diagnosis and tends to recur locally. Although surgical methods constitute the primary treatment, we believe that a multidisciplinary treatment strategy should be used in high-risk patients with large primary tumors and tumor positive margins.

Management of Localized Breast Angiosarcoma by North American Radiation and Medical Oncologists

INTRODUCTION

Primary breast angiosarcoma is a rare malignancy with no clinical trials to guide management. The current use of surgery, chemotherapy, and radiotherapy among North American oncologists is unknown.

PATIENTS AND METHODS

An institutional review board-approved anonymous electronic survey was distributed to 9660 practicing North American radiation and medical oncologists. Questions pertained to treatment recommendations for localized nonmetastatic primary breast angiosarcoma, as well as knowledge/use of β-blockers in angiosarcoma. The Fisher exact test was used to compare responses of medical and radiation oncologists.

RESULTS

Surgery was recommended by 95% of all respondents. Chemotherapy was recommended by over half of medical and radiation oncologists. Radiotherapy was recommended by 92% of radiation and 56% of medical oncologists. The most common treatment recommendation was a trimodal treatment, with up-front surgery followed by adjuvant chemotherapy, then by adjuvant radiotherapy. Twenty-two percent of respondents were aware of clinical data pertaining to the use of β-blockers in management of angiosarcoma, and among these respondents 69% were comfortable incorporating this treatment into standard practice.

CONCLUSION

Trimodal management of primary localized breast angiosarcoma is supported by North American radiation and medical oncologists, with the majority recommending up-front surgery followed by adjuvant chemotherapy and radiation. The recently published reports of successful use of β-blockers are not yet known among North American clinicians, but there is a great enthusiasm to incorporate these commonly prescribed medications into standard practice. These findings may greatly influence the standard of care for breast angiosarcoma treatment, particularly given the absence of Level I-supported evidence.

Diagnostic difficulties of primary angiosarcoma of the breast: a case report

Background

Angiosarcoma of the breast is a rare tumor, which may be primary or secondary to breast surgery or irradiation. It is characterized by polymorphic and nonspecific clinical and radiological features. A pathologist plays a key role in positive and differential diagnosis and in establishing the prognosis: only a histological examination can confirm the diagnosis, and the histologic grade is the most important prognostic factor. In fact, angiosarcomas of the breast constitute a very heterogeneous group and they are classified into three grades based on the degree of differentiation. We will illustrate diagnostic challenges through this new case of primary angiosarcoma of the breast. Microscopic findings were initially interpreted as a benign vascular tumor. We will also discuss the relevant medical literature.

Case presentation

A 56-year-old Arabian woman presented with a palpable right breast mass that had been enlarging for 2 months, measuring 5 cm, without axillary lymphadenopathy. She had no personal or family history of breast surgery or breast irradiation. A mammography showed no evidence of spiculation. No suspicious calcifications were seen. A needle core biopsy was performed. Microscopic findings were initially interpreted as a benign vascular tumor. However, as the mass measured 5 cm, the diagnosis of angiosarcoma was more appropriate, and mastectomy without axillary dissection was performed. Microscopic examination found mild to moderately scattered pleomorphic cells, and scattered mitotic figures. It also showed papillary formations, solid foci of spindle cells, and hemorrhagic necrosis. The margins of the tumor were infiltrative. The diagnosis of primary intermediately differentiated angiosarcoma of the breast (grade II) was made. No distant metastases were found. Our patient was lost to follow-up and further treatment after mastectomy until she developed local tumor progression 4 months later.

Conclusions

Through this case report, we emphasize the importance of clinicopathological confrontation in angiosarcoma of the breast.

Recurrent Primary Angiosarcoma of the Breast Presenting as Kasabach-Merritt Syndrome: A Case Report and Review of Literature

Angiosarcoma of the breast is an unusual tumour. The diagnosis of this condition is difficult clinically, pathologically and radiologically. Treatment includes surgery followed by chemoradiation. The tumour is notorious for its recurrence and is generally associated with poor prognosis. Kasabach-Merritt syndrome also is a very rare entity seen primarily in infants with vascular malformations and carries a poor prognosis. In this report, the authors describe a patient with recurrent primary angiosarcoma of the breast, which presented as Kasabach-Merritt syndrome.

Management experiences of primary angiosarcoma of breast: a retrospective study from single institute in the People's Republic of China

Background

Primary angiosarcoma of breast (PAOB) is a rare and highly aggressive malignancy. There is no general agreement on optimal treatments or prognostic factors for this orphan disease. The objective of this study was to investigate the clinicopathologic features and management experiences of PAOB.

Methods

We performed a retrospective review of medical and pathologic records of 17 consecutive patients diagnosed with PAOB between January 2000 and February 2014 at FuDan University Shanghai Cancer Center. We evaluated the clinical characteristics, multimodality treatments, and associated clinical outcomes.

Results

A total of 16 patients were included in this retrospective study (median age at PAOB presentation 33.5 years, range: 19–56 years). Palpable tumor with or without breast skin ecchymosis presented as the most common initial symptom. All patients underwent surgery with curative intent. Median disease-free survival and overall survival (OS) were 9 months and 13.6 months, respectively. One-year and 3-year disease-free survival rates were 43.8% and 6.3%, with OS rates of 93.8% and 78.1%, respectively. High histologic grade indicated poorer OS by univariate analysis (P=0.01). However, neither adjuvant chemotherapy nor radiotherapy contributed to clinical outcomes in our series.

Conclusion

PAOB is considered as an infrequent breast neoplasm with aggressive characteristics. Histologic grade and early metastasis (within 12 months after diagnosis) are associated with poor prognosis. Regardless of grade, additional benefit was not observed with adjuvant therapy.

Primary breast angiosarcoma: pathological and radiological diagnosis

Primary breast angiosarcoma is a very rare aggressive mesenchymal tumor, which may represent only 0.04% of all breast malignant tumors. We report a case of primary angiosarcoma in the breast of a 22-year-old woman who presented with a mass in her right breast. Ultrasonography revealed a large heterogeneous lobulated mass lesion consistent with a fibroadenoma or phyllodes tumor. After a period of six months, she presented with nipple retraction, so a core needle biopsy was performed. Histopathology revealed a well differentiated angiosarcoma (grade I/III), but in the mastectomy specimen, numerous neoplastic multinucleated giant cells were evident, which resembled those found in other sarcomas, such as malignant fibrous histiocytoma or extra skeletal osteogenic sarcoma, and this caused difficulty making the diagnosis. Using immunohistochemical (IHC) studies, neoplastic cells were positively stained for CD31, CD34, and factor VIII-related antigens, which confirmed that the tumor was a high grade, poorly differentiated angiosarcoma (grade III/III). In conclusion, angiosarcomas may have different grade patterns in the same tumor, and as a result it is necessary to examine the whole tumor for definite grading. Imaging findings in angiosarcomas are non-specific, therefore they may misdiagnosed, frequently by other benign lesions.
