A case of primary breast synovial sarcoma diagnosed in a young female patient / 대한내과학회지

ABSTRACT

Synovial sarcoma is a malignant soft tissue neoplasm that develops mainly in para-articular locations in the extremities, but can arise in a wide variety of other sites. Primary breast synovial sarcoma has been reported infrequently worldwide. We report the case of 15-year-old female who was diagnosed with primary breast synovial sarcoma. We performed wide excision for the breast mass. However, local recurrence was detected 9 months later. We performed wide excision for the recurrent breast tumor. After 27 months, a solitary metastasis was found in the right upper lobe of the lung. We performed wedge resection for the lung mass and treated her with palliative chemotherapy using doxorubicin and ifosfamide. Twenty-eight months after chemotherapy, she is alive without evidence of recurrence. We report the details of this case along with a review of the literature.
