Chest wall schwannomas are rare tumors arising from the intercostals nerves. Schwannomas are lobulated, encapsulated spherical masses, different from neurofibromas in that matter. Men and women are equally affected in their third and fourth decades.
A 42 year old female presented with a 6 month history of progressively worsening pain over the right shoulder and chest wall, aggravated by movement and with associated right arm oedema and paraesthesia. She believed mild symptoms began 2 years prior to presentation. The histopathological examination revealed a benign lesion; a schwannoma with degenerative changes. The section revealed a benign nerve sheath tumor characterized by a proliferation of band spindle cells arranged in fascicles and variable cellularity and associated with dilated and think walled blood vessels.
Chest wall schwannomas are rare; they mimic chest wall malignant lesions.
胸壁神经鞘瘤是起源于肋间神经的罕见肿瘤。神经鞘瘤呈分叶状、有包膜的球形肿块，在这方面与神经纤维瘤不同。男女在第三和第四个十年受影响的几率相同。
一名42岁女性，有6个月的右肩和胸壁疼痛逐渐加重的病史，运动时加重，并伴有右臂水肿和感觉异常。她认为轻微症状在就诊前2年就已开始。组织病理学检查显示为良性病变；一个有退行性改变的神经鞘瘤。切片显示为良性神经鞘瘤，其特征是束状排列的带状梭形细胞增殖、细胞密度可变，并伴有扩张的薄壁血管。
胸壁神经鞘瘤罕见；它们酷似胸壁恶性病变。
