[Breast angiosarcoma: a case report]

Giant primary angiosarcoma of an adolescent girl's breast diagnosed postmortem: a case report

Background

Angiosarcoma is an endothelial malignant tumor; angiosarcoma located in the breast is extremely rare, less than 0.01%. We report a case of a giant angiosarcoma diagnosed postmortem in a 16-year-old girl in a resource-constrained country.

Case presentation

A 16-year-old black African girl was admitted for altered consciousness and a left breast tumor. She was admitted in a state of apparent death. Her death was confirmed on clinical examination. A postmortem biopsy of the mammary tumor showed standard histology of a proliferation of fusiform or rounded tumor cells in places, which were not very cohesive with marked anisokaryosis and numerous foci of tumor necrosis. Immunohistochemistry showed a positivity of CD31 and factor VIII markers with a proliferation index (Ki-67) estimated at 30%.

Conclusion

Primary angiosarcoma of the breast is exceptional in adolescents and has a poor prognosis, especially in countries with limited resources.

[Radiation-induced breast angiosarcoma: about a case]

Breast angiosarcoma is a rare vascular endothelial connective tissue tumor. It is primitive in young patients and radio-induced in older subjects. It is a malignant tumor and it manifests with polymorphic clinical and radiological features. Its prognosis is poor due to the frequent occurrence of visceral metastases and fast recurrence. We here report a case of breast angiosarcoma in a female patient aged 43 years, with a history of breast cancer, treated by conservative surgery and adjuvant radiotherapy. The purpose of this study is to highlight the epidemiological diagnostic and therapeutic features of these rare aggressive tumors.

Recurrence of Primary Breast Angiosarcoma 7 Years after Mastectomy in a 17-Year-Old Woman: A Case Report

Background

Primary breast angiosarcoma is a rare neoplasm; breast angiosarcoma patients under 20 years old are extremely rare. The prognosis is often poor due to a high relapse rate after surgical resection.

Case Report

We report on a case of a 17-year-old woman suffering from a primary breast angiosarcoma, associated with the local recurrence of a right-breast angiosarcoma 86 months after mastectomy. She received extensive local excision and transplantation of an adjacent skin flap. The post-operation diagnosis was angiosarcoma of histological grade III.

Conclusions

This is a rare case as the patient was below 18 years old and the follow-up was greater than 5 years. Taken together, long-term close follow-up is extremely important, regardless of how long after surgery and the status of the surgical margins.

Primary breast angiosarcoma: a rare presentation of rare tumor - case report

BACKGROUND

Primary breast angiosarcoma is defined as malignant proliferation showing endothelial differentiation. It is a very rare tumour (0.05% of primary mammary cancers), whose diagnosis can be difficult.

CASE PRESENTATION

We report the observation of a patient with no previous history, aged 27 years. The clinical examination finds a right breast discreetly increased in volume. The trucut biopsy was in favour of a lactating tubular adenoma. However, an immunohistochemical complement was requested. An absence of pancytokeratin labelling contrasted with strong expression of CD31, CD34 (endothelial markers) are described. The proliferation index (Ki67) was estimated at 30%. This led to the conclusion that the phenotypic aspect is related to a vascular proliferation that evokes an angiosarcoma. After a multidisciplinary assessment, the patient benefited from an enlarged excision of the tumour. The histopathological examination of the surgical specimen found an infiltrating mesenchymal proliferation made of vessels of variable sizes anastomosed to vascular slits with lesional limits. The immunohistochemical examination on the surgical specimen showed to the same phenotypic profile on biopsy. The final diagnosis was a high-grade mammary angiosarcoma of incomplete excision. The patient refused any additional surgical management; external radiotherapy and close supervision were prescribed. After eight months of evolution, no local or remote recurrence was reported.

CONCLUSION

Primary breast angiosarcoma is a mesenchymal malignant tumour of rare vascular origin. Our observation is peculiar by the absence of any prior radiotherapy, its clinical presentation, its morpho-phenotypic characteristics, its management and its evolutive aspects.

[Rare benign breast tumors including Abrikossoff tumor (granular cell tumor), erosive adenomatosis of the nipple, cytosteatonecrosis, fibromatosis (desmoid tumor), galactocele, hamartoma, hemangioma, lipoma, juvenile papillomatosis, pseudoangiomatous hyperplasia, and syringomatous adenoma: Guidelines for clinical practice]

OBJECTIVES

To provide guidelines for clinical practice from the French College of Gynaecologists and Obstetricians (CNGOF), based on the best evidence available, concerning rare benign breast tumors: Abrikossoff (granular cell tumor), erosive adenomatosis of the nipple, cytosteatonecrosis, fibromatosis (desmoid tumor), galactocele, hamartoma, hemangioma, lipoma, juvenile papillomatosis, pseudoangiomatous hyperplasia, and syringomatous adenoma.

METHODS

Bibliographical search in French and English languages by consultation of Pubmed, Cochrane and international databases.

RESULTS

For erosive adenomatosis of the nipple, surgical excision is recommended to exclude Paget's disease or cancer (grade C). When surgery is performed for breast desmoid tumor or syringomatous adenoma, free margins are recommended (grade C). Without clinico-radio-histologic discordance, surgical abstention may be proposed for Abrikossoff tumor (granular cell tumor), cytosteatonecrosis, galactocele, hamartoma, hemangioma, lipoma, juvenile papillomatosis, pseudoangiomatous hyperplasia, and syringomatous adenoma (grade C).
