Granular cell tumor is a rare, usually benign neoplasm of neural origin that may arise in virtually any site and, when situated in the breast, can mimic breast carcinoma. We describe a case of granular cell tumor of the breast in a 57-yr-old woman. Clinical evaluation, mammography, sonography and MRI suggested a carcinoma with infiltration of skin and muscle. However, the tumor did not display increased glucose metabolism on PET. Clinical findings, imaging results, histological characteristics and surgical management are discussed.
颗粒细胞瘤是一种罕见的、通常起源于神经的良性肿瘤，几乎可发生于任何部位，位于乳腺时可酷似乳腺癌。我们报告一例57岁女性乳腺颗粒细胞瘤病例。临床评估、乳腺钼靶、超声及磁共振成像提示为浸润皮肤和肌肉的癌。然而，该肿瘤在正电子发射断层显像（PET）上未显示葡萄糖代谢增加。本文讨论了其临床发现、影像学结果、组织学特征及外科治疗。
