Poroid neoplasms are benign epithelial proliferations with eccrine sweat gland differentiation. They are a challenging diagnosis because of the clinical heterogeneity, being able to mimic several malignant neoplasms. They are classified into classic poroma, hidroacanthoma simplex, dermal duct tumor and poroid hidradenoma. Association of histological subtypes occurs in more than 25% of cases. We report a case of a combined poroid neoplasia of classical poroma and poroid hidradenoma, reviewing its dermatoscopic features.
多孔状肿瘤是具有小汗腺分化的良性上皮增生。由于临床异质性,它们是具有挑战性的诊断,能够模仿几种恶性肿瘤。它们分为经典汗孔瘤、单纯性汗腺棘皮瘤、真皮导管瘤和多孔状汗腺腺瘤。超过25%的病例存在组织学亚型的联合。我们报告一例经典汗孔瘤和多孔状汗腺腺瘤合并的多孔状肿瘤病例,并回顾其皮肤镜特征。
