Zosteriform Dissemination of Molluscum Contagiosum Infection Diagnosed in an Immunocompetent Girl: A Rare Clinical Presentation.

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.

Mosaic Darier's Disease: A Case of Unilateral Localized Type I Segmental Darier's Disease.

Darier's disease (DD), also known as Darier-White disease, is a rare autosomal dominant genodermatosis resulting from mutations in the ATP2A2 gene. It commonly manifests as keratotic papules or plaques in seborrheic areas and is often triggered by heat, sweating, and trauma. A rare mosaic variant, segmental Darier's disease, occurs due to post-zygotic mutations and presents along Blaschko's lines.
