Cutaneous leishmaniasis is characterized by ulcers with raised edges and a granular bottom, mainly on the lower limbs. This is a case report of a male patient with an ulcer on the left plantar region. The diagnosis was confirmed by positive PCR for L. braziliensis and the presence of amastigotes of Leishmania sp. in the histopathological examination. After treatment with Glucantime, the patient showed full healing of the ulcer. The unusual location of the ulceration calls attention to atypical presentations of leishmaniasis, and the importance of histopathological examination and PCR, leading to the appropriate diagnosis and treatment.
皮肤利什曼病的特征是边缘隆起、底部呈颗粒状的溃疡，主要发生在下肢。这是一例左足底区域出现溃疡的男性患者。通过对 L. braziliensis 的 PCR 检测呈阳性和组织病理学检查中存在利什曼原虫的无鞭毛体，确诊为该病。经葡聚糖胺治疗后，患者的溃疡完全愈合。溃疡的不寻常位置提示利什曼病的非典型表现，组织病理学检查和 PCR 的重要性，从而进行了适当的诊断和治疗。
