Mucocutaneous leishmaniasis (MCL) is a chronic infection that can affect the skin and mucous membranes. We report a case of oral, nasopharyngeal, and penile lesions in a 35-year-old cocaine user. The patient presented with ulcerated lesions in 2014. Histopathologic analysis revealed amastigotes, and serological test results were positive for leishmaniasis. Systemic therapy with meglumine antimoniate was administered; however, the patient failed to present for follow-up. In 2018, he returned with nasal collapse, and another histopathologic test confirmed MCL. This case illustrates the importance of careful differential diagnosis of skin and mucous ulcers to identify the particular pathology.
黏膜皮肤利什曼病（MCL）是一种慢性感染，可影响皮肤和黏膜。我们报告了一例 35 岁可卡因使用者的口腔、鼻咽和阴茎病变。患者于 2014 年出现溃疡性病变。组织病理学分析显示存在无鞭毛体，血清学检测结果利什曼病阳性。给予葡甲胺锑治疗全身治疗；然而，患者未能进行随访。2018 年，他因鼻塌陷再次就诊，另一次组织病理学检查证实为 MCL。该病例说明了仔细鉴别皮肤和黏膜溃疡以确定特定病理的重要性。
