Chromoblastomycosis is a subcutaneous mycosis with chronic evolution that mainly affects the lower limbs and, less frequently, the auricles. Clinically, it presents with papillary verrucous, nodular, and/or tumoral lesions, whether isolated or infiltrated, forming plaques and, sometimes, atrophic in some areas. Histopathologically, it is characterized by a dermal granulomatous inflammatory infiltrate, and the diagnosis can be confirmed by the presence of fumagoid bodies in anatomopathological or direct mycological exams. The treatment to be indicated will depend on the extent and location of the lesions, using systemic antifungals, surgical removal, cryotherapy, thermotherapy, and immunoadjuvants. The present study reports an atypical presentation of chromoblastomycosis on the auricle.
着色芽生菌病是一种具有慢性病程的皮下真菌病，主要累及下肢，较少累及耳廓。临床上，表现为乳头状疣状、结节状和/或肿瘤样病变，可为孤立性或浸润性，形成斑块，有时在某些区域出现萎缩。组织病理学上，其特征为真皮肉芽肿性炎性浸润，在解剖病理学或直接真菌学检查中发现烟曲霉样小体可确诊。所选用的治疗方法将取决于病变的范围和部位，可采用全身抗真菌药、手术切除、冷冻疗法、热疗法和免疫佐剂。本研究报告了一例耳廓着色芽生菌病的非典型表现。
