We report 2 cases of invasive ductal carcinoma of the breast occurring near a phyllodes tumor. The first case was ofa 58- year-old woman who had a tumor in her right breast and visited our hospital. Following a core needle biopsy (CNB), a malignant phyllodes tumor was diagnosed. We performed a lumpectomy for the phyllodes tumor, with 1.5-cm surgical margins. Pathological diagnosis of the resected specimen confirmed the malignant phyllodes tumor. A ductal carcinoma in situ (DCIS) was also discovered near the phyllodes tumor. The second case was of another 58-year-old woman who had a big tumor in her right breast and visited our hospital. CNB resulted in pathological diagnosis ofa benign phyllodes tumor. The tumor was removed by a lumpectomy with 1.5-cm surgical margins. The pathological diagnosis from the resected specimen was borderline phyllodes tumor with invasive ductal carcinoma in the proximity. In both cases, DCIS could not have been diagnosed preoperatively.
我们报告2例发生在叶状肿瘤附近的乳腺浸润性导管癌。第一例是一名58岁女性，其右乳有一个肿瘤，前来我院就诊。在进行粗针穿刺活检（CNB）后，诊断为恶性叶状肿瘤。我们对叶状肿瘤进行了肿块切除术，手术切缘为1.5厘米。切除标本的病理诊断证实为恶性叶状肿瘤。在叶状肿瘤附近还发现了导管原位癌（DCIS）。第二例是另一名58岁女性，其右乳有一个大肿瘤，前来我院就诊。CNB病理诊断为良性叶状肿瘤。通过肿块切除术切除肿瘤，手术切缘为1.5厘米。切除标本的病理诊断为交界性叶状肿瘤，附近有浸润性导管癌。在这两例中，术前均未诊断出DCIS。
