We report an 18-year-old male who presented with a two-month history of a lesion over his right forearm with a one-week history of sudden increase in size associated with pain. General and systemic examinations were normal. Dermatological examination revealed a single tender, well-defined, pearly white to erythematous, dome-shaped nodule of approximately 6mm x 5mm x 5mm with central umbilication and surrounding erythema. Dermoscopy revealed a central poly lobular white-yellow amorphous structure with a peripheral punctiform vascular pattern, collarette of scaling, and circumferential homogenous red area. Intracytoplasmic eosinophilic and basophilic inclusion bodies were found on the Tzanck smear. With the above clinical and dermoscopic findings, a diagnosis of molluscum contagiosum (MC) with molluscum dermatitis was made. Following curettage and removal of the contents of the lesion, the surrounding inflammation resolved completely within 20 days. This report emphasizes the fact that curettage of the primary MC lesion itself leads to the resolution of molluscum dermatitis, negating the need for additional topical steroid therapy. The unreported dermoscopic features of molluscum dermatitis in this report provide valuable insights into distinguishing molluscum dermatitis from other dermatological conditions with similar presentations.
我们报告一名18岁男性,其右前臂出现一个皮损已有两个月,在一周内突然增大并伴有疼痛。全身检查正常。皮肤科检查发现一个单发的、触痛的、边界清晰的、珍珠白色至红斑样的圆顶状结节,大小约为6mm×5mm×5mm,中央有脐凹,周围有红斑。皮肤镜检查显示中央为多叶状白色至黄色无定形结构,外周为点状血管模式、鳞屑性衣领样改变及周边均匀红色区域。Tzanck涂片发现胞质内嗜酸性和嗜碱性包涵体。根据上述临床和皮肤镜检查结果,诊断为传染性软疣(MC)合并软疣性皮炎。刮除并清除皮损内容物后,周围炎症在20天内完全消退。本报告强调了一个事实,即对原发性MC皮损进行刮除本身可使软疣性皮炎消退,无需额外的外用糖皮质激素治疗。本报告中未报道的软疣性皮炎的皮肤镜特征为区分软疣性皮炎与其他表现相似的皮肤病提供了有价值的见解。
