Акрокератоз верукозний Хопфа

Визначення(English summary)

A rare, genetic, acrokeratoderma disease characterized by multiple, symmetrical, asymptomatic, skin-colored (rarely, brownish), flat-topped, wart-like papules located on the dorsal aspects of the hands and feet (occasionally found on other parts of the body, such as knees, elbows and forearms), typically associated with palmoplantar punctate keratosis and variable nail involvement (including leukonychia, thickening, ridging, longitudinal striations and splitting). Histology reveals undulating hyperkeratosis, papillomatosis, hypergranulosis, and acanthosis, creating a characteristic 'church spire' appearance, with no acantholysis nor dyskeratosis associated.
