A 28-year-old woman presented with a painful rash on her right thigh. Five days before presentation, she had been walking on sea rocks on an island in the Cyclades region of Greece when she fell, landing on her buttocks. She immediately felt a severe pain in her right thigh, and an itchy, red lesion developed. On physical examination at the current presentation, innumerable fine, erythematous, linear lesions in a stellate distribution, with central clearing, on the posterior right thigh were seen. By what marine animal did the patient most likely get stung?

一名28岁女性右大腿出现疼痛性皮疹。就诊前5天，她在希腊基克拉泽斯群岛的一个岛屿上走在海礁上时摔倒，臀部着地。她立刻感到右大腿剧痛，并出现一处瘙痒、发红的病变。本次就诊时进行体格检查，发现右大腿后侧有无数细小的、红斑状的、呈星状分布的线性病变，中央区域皮损消退。该患者最有可能是被哪种海洋动物蜇伤？

A. Coral珊瑚

B. Jellyfish水母

C. Sea anemone海葵

D. Sea urchin海胆

E. Stingray鳐鱼

答案解析：

诊断为海葵蜇伤。海葵蜇伤所致的病变表现为疼痛性的圆形病灶，通常中央区域皮损会消退。皮肤接触海葵毒液会导致伤口局部发炎。希腊基克拉泽斯群岛是地中海地区已知有大量海葵分布的区域。

正确答案：C
