The purpose of this report is to present a case of orbital rhabdomyosarcoma (RMS) masquerading as a dermoid cyst. A six-year-old boy with an unremarkable medical history presented in the outpatient department with a palpable mass in the superonasal region of the right orbit, which had rapidly grown in the past month. The most likely diagnosis was dermoid cyst and the patient was scheduled for surgical excision. A high index of suspicion was raised intraoperatively based on the appearance of the lesion due to the presence of a feeder vessel. The histopathology examination identified alveolar RMS. The patient was referred to a pediatric oncology department and commenced intravenous chemotherapy. RMS may masquerade as various conditions, including dermoid cysts and chalazion. A high index of suspicion should be raised in cases with rapidly growing lesions.
本报告旨在介绍一例伪装成皮样囊肿的眼眶横纹肌肉瘤（RMS）病例。一名既往病史无异常的6岁男孩在门诊就诊，其右眼眶鼻上区域可触及肿块，该肿块在过去一个月内迅速增大。最可能的诊断是皮样囊肿，患者被安排进行手术切除。术中由于发现有一支供血血管，基于病变外观引发了高度怀疑。组织病理学检查确诊为肺泡型RMS。患者被转诊至儿科肿瘤科并开始静脉化疗。RMS可能会伪装成多种病症，包括皮样囊肿和睑板腺囊肿。对于病变迅速生长的病例应提高警惕。
