We report a rare case of neurofibromatosis type-2 (NF-2) associated with a chest wall schwannoma that was initially suspected of being a breast tumor. The patient was a 28-year-old female who was diagnosed as having NF-2 at 19 years old. At that time, she noticed a mass in the upper lateral region of her left breast but did not have it examined. The mass grew and became painful, and she was therefore referred to our department. Results of the initial examination indicated the possibility of a breast tumor, but a diagnosis of extramammary tumor of the major pectoralis major muscle was made on the basis of the results of ultrasonography and 3-dimensional computed tomography (3D-CT). An endoscope-assisted extirpation of the tumor was performed. Histologically, the tumor was an Antoni type A and B neurilemoma and was diagnosed as a schwannoma.
我们报告一例罕见的2型神经纤维瘤病（NF - 2）合并胸壁神经鞘瘤，该肿瘤最初被怀疑为乳腺肿瘤。患者为一名28岁女性，19岁时被诊断为NF - 2。当时，她注意到左乳房上外侧区域有一个肿块，但未进行检查。肿块逐渐增大并伴有疼痛，因此她被转诊至我科。初步检查结果提示可能为乳腺肿瘤，但根据超声和三维计算机断层扫描（3D - CT）结果诊断为胸大肌乳腺外肿瘤。在内镜辅助下对肿瘤进行了切除。组织学检查显示，该肿瘤为Antoni A型和B型神经鞘瘤，诊断为神经鞘瘤。
