Perianal cutaneous amebiasis is a rare entity, with 0.03% to 0.07% reported incidence. We present two cases of perianal cutaneous amebiasis, both in male patients. Diagnosis was established by biopsy, with demonstration of Entamoeba histolytica trophozoites. Treatment with metronidazol was performed with good outcome. Although incidence of perianal cutaneous amebiasis is low, this entity must be kept in mind when painful atypical ulcers appear in this region. Diagnosis must be confirmed by identification of the parasite and treatment must be established with antiamebic extra-luminal drugs.
肛周皮肤阿米巴病是一种罕见疾病，报告发病率为0.03%至0.07%。我们报告两例肛周皮肤阿米巴病，均为男性患者。通过活检发现溶组织内阿米巴滋养体而确诊。采用甲硝唑治疗，效果良好。尽管肛周皮肤阿米巴病的发病率较低，但当该区域出现疼痛性非典型溃疡时，必须考虑到这种疾病。必须通过识别寄生虫来确诊，并用抗阿米巴肠外药物进行治疗。
