Rhabdomyosarcoma is the most common soft tissue tumour in children and adolescents, but extremely rare in adults with comparatively worse outcomes. Metastatic disease is not uncommon, but intra-abdominal metastases are exceedingly rare. We report an unusual case of ileal metastases from an upper extremity rhabdomyosarcoma in a 17-year-old male who presented with abdominal pain during a routine follow-up visit. Laparotomy and ileocecectomy for a perforated ileal mass confirmed metastatic embryonal rhabdomyosarcoma with 1 out of 14 positive lymph node metastases. This case demonstrates that, although rare, intra-abdominal metastases should be considered when patients with a rhabdomyosarcoma present with abdominal complaints.
横纹肌肉瘤是儿童和青少年中最常见的软组织肿瘤，但在成年人中极为罕见，且预后较差。转移疾病并不罕见，但腹腔内转移极为罕见。我们报告了一例罕见的 17 岁男性上肢横纹肌肉瘤累及回肠的病例，该患者在常规随访时出现腹痛。剖腹探查和回盲部切除术切除穿孔的回肠肿块，证实为转移性胚胎性横纹肌肉瘤，14 个淋巴结中有 1 个转移阳性。该病例表明，尽管罕见，但当横纹肌肉瘤患者出现腹部症状时，应考虑腹腔内转移。
