Eccrine syringofibroadenoma (ESFA) is a rare disorder. We report the first case of ESFA of the nail apparatus, which presented as a yellow longitudinal onycholytic band of the left fourth finger over an intermittently painful subungual filamentous tumour. Histological examination showed features of ESFA with a digitate pattern of papillomatosis due to the specialized physiological longitudinal arrangement of the ridges in the nail bed. In addition, we describe a new feature of colloidal iron-positive clear cells. In our case, the presence of two types of cells with a central ductal differentiation and a significant amount of mucopolysaccharides in clear cells could suggest differentiation towards both the ductal and the secretory portion of the eccrine gland.
小汗腺汗管纤维腺瘤(ESFA)是一种罕见的疾病。我们报告了首例甲器ESFA病例,表现为左手无名指黄色纵向甲剥离带,其下方有间歇性疼痛的甲下丝状肿瘤。组织学检查显示ESFA的特征,由于甲床嵴的特殊生理性纵向排列,呈现出指状乳头瘤病模式。此外,我们描述了一种胶体铁阳性透明细胞的新特征。在我们的病例中,存在两种具有中央导管分化的细胞以及透明细胞中大量的粘多糖,这可能提示向小汗腺导管和分泌部的分化。
