A 32 year-old Malay lady presented with a swelling over the dorsal surface of her right thumb for 6 months. The swelling was non-tender, smooth surfaced, mobile and nonfluctuating with no bony involvement. The provisional diagnosis was ganglion cyst. Excisional biopsy did not show features of ganglion cyst as it appeared to be wellencapsulated, multi-lobulated and yellowish in colour. Histopathological examination showed that it was a schwannoma. Schwannomas are relatively rare benign tumours which are frequently misdiagnosed. In this case, it was misdiagnosed both as a ganglion and a lipoma.
一名32岁的马来女性因右手拇指背侧肿胀6个月前来就诊。该肿胀无压痛，表面光滑，可活动，无波动感，且未累及骨质。初步诊断为腱鞘囊肿。切除活检显示其并非腱鞘囊肿的特征，因为它似乎有完整包膜、多叶且呈黄色。组织病理学检查表明这是一个神经鞘瘤。神经鞘瘤是相对罕见的良性肿瘤，常被误诊。在这个病例中，它先后被误诊为腱鞘囊肿和脂肪瘤。
