Abstract
A 60-year-old woman was seen at the hospital because of a right breast mass enlarged rapidly during these four months. The mass was 24 cm in diameter on admission. Malignant phyllodes tumor seemed a likely diagnosis from gross, MRI and CT findings and mastectomy was performed. Since preoperative examinations revealed no regional lymph node swelling and phyllodes tumors are reported to metastasize to lymph nodes in a low frequency, axillary lymph node dissection was not done. From immunohistochemistry of the permanent pathological specimen, stromal sarcoma showing differentiating tendency into various directions was diagnosed.
Stromal sarcoma of the breast is a rare entity and most clinicopathological behavious of the tumor have been still unknown. We herein report a patient with an over 20-cm sized stromal sarcoma of the breast who has been free from any recurrences including local recurrence as of three years after the operation, with some bibliographic comments.
