Molluscum contagiosum (MC) is a benign, self-limiting infectious lesion that primarily affects children and young adults, especially those with immunodeficiency. MC is caused by a poxvirus from the Molluscipoxvirus genus of the Poxviridae family. Diagnosis is mainly clinical, with lesions presenting as dome-shaped, spherical, solid, flesh-colored, pearly papules with central umbilication. MC commonly appears on the limbs, face, trunk, and axillary regions. The differential diagnosis includes inflammatory, infectious, and neoplastic causes, varying by age and immunological condition. This case report presents a rare zosteriform distribution of MC infection in an immunocompetent girl, a presentation described only twice in medical literature. The unusual distribution resulted from scratching, a process known as the Koebner phenomenon (pseudo-koebnerization).
传染性软疣（MC）是一种良性、自限性感染性损害，主要影响儿童和年轻人，尤其是免疫功能低下者。MC由痘病毒科软疣痘病毒属的一种痘病毒引起。诊断主要依靠临床症状，皮损表现为圆顶形、球形、坚实、肤色、珍珠样丘疹，中央有脐凹。MC常见于四肢、面部、躯干和腋窝部位。鉴别诊断包括炎症性、感染性和肿瘤性病因，因年龄和免疫状况而异。本病例报告呈现了一名免疫功能正常女孩罕见的带状疱疹样分布的MC感染，这种表现仅在医学文献中被描述过两次。这种不寻常的分布是由搔抓引起的，这一过程称为同形反应（假同形反应）。
