Histopathological analysis of chronic paronychia.

Background: Chronic paronychia is an inflammatory process of the nail folds lasting more than 6 weeks. Clinically, there is hypertrophy and retraction of the folds and absence of the cuticle. Treatment involves clinical measures and, when there is no response or the hypertrophy of the folds is very pronounced, surgical treatment is indicated.

Description of the most severe signs in nail lichen planus: a strategy to contribute to the diagnosis of the severe stage.

Background: Severe nail lichen planus (NLP) does not respond well to treatment and is often poorly considered and described in detail.

Objective: We sought to describe the characteristics of severe NLP.

Methods: A retrospective data analysis was performed, including the photographic records of the most compromised nails of patients with NLP over 18 years old, who consulted between 2009 and 2019 at the Instituto de Dermatologia Professor Rubem David Azulay in Rio de Janeiro, Brazil.
