Scalp schwannomas are rare, benign peripheral nerve sheath tumors often misdiagnosed due to their nonspecific presentation. They typically present as slow-growing, painless subcutaneous nodules, most commonly in the occipital region.
We report a 29-year-old female with a gradually enlarging, painless occipital scalp nodule for 7 months. Clinically, it was suspected to be a lipoma or pilar cyst. Excision under local anesthesia revealed a well-encapsulated, yellowish mass. Histopathology confirmed a benign schwannoma. The patient had an uneventful recovery with no recurrence at 6-month follow-up.
Scalp schwannomas, though rare, exhibit characteristic clinical and histopathological features. They are frequently misdiagnosed due to their rare occurrence as well as their clinical and radiological resemblance to other benign lesions. Complete surgical excision is the preferred treatment, offering an excellent prognosis with minimal risk of recurrence. Extended follow-up is recommended to monitor potential late recurrences.
头皮神经鞘瘤较为罕见，是一种良性周围神经鞘膜肿瘤，因其表现不具特异性，常被误诊。它们通常表现为生长缓慢、无痛的皮下结节，最常见于枕部区域。
我们报告一名29岁女性，枕部头皮有一无痛性结节，逐渐增大7个月。临床上，怀疑为脂肪瘤或毛囊囊肿。局部麻醉下切除显示为一个包膜完整的黄色肿物。组织病理学证实为良性神经鞘瘤。患者恢复顺利，6个月随访无复发。
头皮神经鞘瘤虽罕见，但具有特征性的临床和组织病理学特征。由于其罕见性以及在临床和影像学上与其他良性病变相似，它们经常被误诊。完整的手术切除是首选治疗方法，预后良好，复发风险极小。建议进行长期随访以监测潜在的晚期复发。
