摘要

摘要平滑肌肉瘤是一种罕见的平滑肌恶性肿瘤。这种疾病累及头颈部非常罕见,耳皮肤平滑肌肉瘤更罕见。这是临床上常被误认为鳞状细胞癌或基底细胞癌的原因,正如本报告中一位85岁男性患者的病例。然而,最后的诊断更加有趣,因为这是一种耳廓去分化平滑肌肉瘤,伴有骨肉瘤的异源成分。耳廓皮肤恶性肿瘤的复发率远高于头颈部其他部位的相应恶性肿瘤,即使在手术切缘阴性的情况下也是如此,而去分化平滑肌肉瘤在临床上更具侵袭性。因此,治疗的选择是全耳切除术,并应注意适当的边缘。

Dedifferentiated Leiomyosarcoma of the Auricle with Heterologous Osteosarcoma Component: Case Report and Literature Review
Leiomyosarcomas are rare malignant tumors of smooth muscles. Head and neck involvement by this disease is very rare, and cutaneous leiomoysarcomas of the ear are even rarer. This is way clinically they are usually mistaken for either squamous or basal cell carcinomas, as was the case in an 85-year-old male patient presented in this report. However, the final diagnosis was even more interesting considering that it was a dedifferentiated leiomyosarcoma of the auricle with a heterologous component of osteosarcoma. The auricular cutaneous malignancies have a much higher rate of recurrence than the corresponding malignancy in other regions of the head and neck, even when resected with negative surgical margins, and dedifferentiated leiomyosarcoma is clinically even more aggressive. Thus, the treatment of choice is a total auriculectomy and great attention should be paid to appropriate margins.
