We describe an adenoid cystic carcinoma on the right breast of a 67-year-old woman. Dynamic magnetic resonance (MR) imaging demonstrated a well-circumscribed round lesion with rapid and marked enhancement on T1-weighted images, without washout of the contrast agent. The enhanced area extended gradually from the margin to the center of the tumor, showing very late enhancement of the tumor center. The findings suggested a tumor with rich stromal component, including adenoid cystic carcinoma of a special type of breast cancer. Histological examination of a lumpectomy disclosed a well-circumscribed tumor consisting of ovoid, trabecular, and irregularly shaped 'nests' of tumor cells, with a focally cribriform pattern. The examination confirmed the diagnosis of adenoid cystic carcinoma of the breast.
我们描述了一名67岁女性右乳的腺样囊性癌。动态磁共振（MR）成像显示一个边界清晰的圆形病变，在T1加权图像上有快速且明显的强化，造影剂无廓清。强化区域从肿瘤边缘逐渐向中心扩展，显示肿瘤中心强化非常延迟。这些表现提示肿瘤具有丰富的间质成分，包括一种特殊类型的乳腺癌——腺样囊性癌。肿块切除术的组织学检查显示一个边界清晰的肿瘤，由卵圆形、小梁状和不规则形状的肿瘤细胞“巢”组成，局部呈筛状结构。检查证实为乳腺腺样囊性癌。
