Dermatofibrosarcoma protuberans in the breast: Case report

초록

INTRODUCTION AND IMPORTANCE: Dermatofibrosarcoma protuberans (DFSP) represents about 1% of soft tissue sarcomas with an estimated incidence of 0.8-5.0 cases per million per year. The involvement of DFSP in breast is very rare and very few cases have been reported in the literature. DFSP was recurred in situ, not spread to distant site. The complete surgical excision with wide, pathologically negative margins of 3 cms is the optimal treatment for primary or recurrent tumor. PRESENTATION OF CASE: A 46-year-old woman presented with palpable lump in the in the right breast. On ultrasonography, a lesion appeared as hypoechoic, circumscribed mass of approximately 37 mm 30 mm in diameter in the upper central part of the right breast. The mass of right breast was demonstrated DFPS by pathologic examination. Chest computerized tomography (CT) scan and 2-[18F]-fluoro-2-deoxyID-glucose (18F-FDG) positron-emission tomography (PET) showed only primary lesion in subcutaneous layer and no enlarged lymph node. The patient underwent excision of the tumor widely. There was no evidence of DFSP local recurrence after five years of follow-up of the patient. DISCUSSION: DFSP is a rare tumor arising from dermis and subcutaneous mesenchymal tissue. Whereas, characteristic imaging feature of DFSP in the breast are not well-defined. The primary treatment for DFSP is considered to be surgical excision. CONCLUSION: DFSP in breast is extremely uncommon and can mimic a primary breast tumor. Surgical excision with adequate resection margins is recommended to ensure local control of the disease. 2021 The Author. Published by Elsevier Ltd on behalf of IJS Publishing Group Ltd.
