Publication date: Available online 7 May 2015 Source:Formosan Journal of Surgery Author(s): Chih-Chiang Hung , Dah-Cherng Yeh , Chen-Hui Lee , Cheng-Chung Wu , Tse-Jia Liu Phyllodes tumors (PTs) are an infrequent breast tumor presentation. An invasive carcinoma arising in a borderline PT is extremely rare. A 58-year-old female presented with a mass over the left breast, which she had had for >1 year, with rapid growth in the past 3 months. The patient underwent wide excision under the assumption that the mass was a PT. Invasive ductal carcinoma and ductal carcinoma in situ arising in a borderline PT were incidentally found. Because the surgical margin was <1 mm, the patient underwent a partial mastectomy to provide a safe margin and a sentinel node biopsy. The pathology of the second excision revealed neither a residual tumor nor lymph node metastasis. The pathologic stage was T2N0M0. This was an extremely rare case of invasive ductal carcinoma arising in a borderline PT, and the clinical course, image, and histological findings are discussed in this paper.
