Primary cylindroma of the breast is extremely rare. To the best of our knowledge, there have been only 18 tumors reported. All of them were benign and had no mitosis. However, the rarity of this entity made the correct diagnosis preoperatively very difficult. Here we present a unique cylindroma with focal brisk mitosis and largest diameter of 5cm in an 80-year woman, she was misdiagnosed as adenoid cystic carcinoma in biopsy and then underwent a radical breast resection. We reviewed the related literature and emphasized differential diagnosis.
乳腺原发性圆柱瘤极其罕见。据我们所知，仅有 18 例肿瘤报道。所有肿瘤均为良性且无有丝分裂。然而，由于该实体罕见，术前正确诊断非常困难。在此，我们报告了一例独特的圆柱瘤，其具有局灶性有丝分裂活跃，最大直径为 5cm，发生于 80 岁女性，在活检中误诊为腺样囊性癌，随后行根治性乳房切除术。我们复习了相关文献并强调了鉴别诊断。
