RESUMEN

Anetoderma or macular atrophy is a rare skin condition of unclear pathogenesis, often associated with autoimmune diseases and skin damage from various infections. Human immunodeficiency virus (HIV), syphilis, and poxviruses have been implicated in the development of anetoderma. A 37-year-old male patient with HIV and recent unprotected sexual encounters presented with more than 400 skin lesions, consistent with Mpox. Symptomatic treatment for Mpox resulted in acute symptom resolution. However, 8 months later he developed papular anetoderma lesions in areas previously affected by Mpox. Biopsy confirmed the loss of elastic fibers in the affected skin areas, leading to the diagnosis of Mpox-induced anetoderma. This report presents a unique case of anetoderma following Mpox in an HIV-positive patient.

RESUMEN

Diagnosis of pityriasis lichenoides et varioliformis acuta (PLEVA) is based on the characteristic pattern of lesions in different stages of development, ranging from erythematous maculopapules to papules with a crusted and/or necrotic centre. However, it may raise the differential diagnosis with other entities. It is therefore not uncommon to have to perform skin biopsies to reach a diagnosis, including in infants. In this study, we report the cases of three patients with PLEVA, highlighting the correlations between the clinical, dermoscopic and histological features. Observation of the dermatoscopic findings described, such as punctate or glomerular vessels and erythematous globules surrounding a homogeneous orange or crusty central area, may allow for a rapid diagnosis, avoiding the need for invasive techniques.
