Schwannoma affect mainly head, neck, and flexor aspect of the limbs. Neurogenic tumors arising from the brachial plexus are rare and axillary schwannoma is extremely uncommon. Cystic degeneration is common in longstanding cases and which when aspirated may yield only macrophages or lymphocytes leading to false diagnosis of the case in spite of strong clinical suspicion. We report one such rare case of a solitary axillary schwannoma with extensive cystic degeneration, which was misdiagnosed on fine needle aspiration cytology and subsequently confirmed by the histopathological examination and immunohistochemistry.
神经鞘瘤主要累及头、颈及四肢屈侧。起源于臂丛神经的神经源性肿瘤罕见，而腋窝神经鞘瘤极为少见。长期存在的病例中常见囊性变，抽吸时可能仅得到巨噬细胞或淋巴细胞，尽管临床高度怀疑，但仍可能导致病例误诊。我们报告了一例如此罕见的孤立性腋窝神经鞘瘤伴广泛囊性变的病例，该病例在细针穿刺细胞学检查中被误诊，随后经组织病理学检查和免疫组化得以确诊。
