A case of granular cell tumor of the breast in a 36-year-old woman is reported. The patient presented with a hard mass,1.5 cm in diameter in the upper-outer quadrant of the left breast. Physical examination and ultrasonography suggested the presence of breast carcinoma. An aspiration biopsy cytology(ABC)specimen wasevaluated as class II, and dynamic magnetic resonance(MR)mammography indicated a benign tumor. Granular cell tumor was finally diagnosed on examination of an excisional biopsy specimen. Granular cell tumor of the breast can mimic breast carcinoma on physical examination, mammography, ultrasonography, and even gross inspection. Dynamic MR mammography has the potential distinguish this condition from carcinoma. Awareness of this disease and prudent use of diagnostic procedures, including MR mammography, will help prevent misdiagnosis and unnecessary surgery.
报告了一例36岁女性乳腺颗粒细胞瘤病例。患者左乳外上象限出现一个直径1.5厘米的硬块。体格检查和超声检查提示存在乳腺癌。针吸活检细胞学（ABC）标本评估为II级，动态磁共振（MR）乳腺造影显示为良性肿瘤。最终经切除活检标本检查确诊为颗粒细胞瘤。乳腺颗粒细胞瘤在体格检查、乳腺造影、超声检查甚至大体检查中都可能酷似乳腺癌。动态MR乳腺造影有可能将这种情况与癌区分开来。认识这种疾病并谨慎使用包括MR乳腺造影在内的诊断程序，将有助于防止误诊和不必要的手术。
