Pioderma gangrenoso associado à poliartrite piogênica / Pyoderma gangrenosum associated with pyogenic polyarthritis

RESUMO

Relata-se o caso de um homem de 28 anos com poliartrite associada a flictenas de fundo arroxeado e líquido claro em pés. Iniciado tratamento para artrite séptica, porém o paciente evoluiu com novos focos de artrite e rompimento das flictenas, desenvolvendo úlceras dolorosas, de bordos eritematosos, com área central de tecido necrótico. As lesões cutâneas progrediram após o desbridamento cirúrgico, levantando-se a hipótese de pioderma gangrenoso (PG). A biópsia do local confirmou o diagnóstico. Iniciou-se corticoterapia, havendo melhora dos sintomas. Esse trabalho ressalta a associação entre PG e poliartrite piogênica, combinação de patologias pouco relatada na literatura.

ABSTRACT

It was reported the case of a 28-year-old man with polyarthritis associated with purple-colored flicten and light fluid in his feet. Treatment for septic arthritis was initiated, but the patient illness evolved with new outbreaks of arthritis and rupture of the flictenes, developing painful ulcers, erythematous borders, with central area of necrotic tissue. Skin lesions progressed after surgical debridement, raising the hypothesis of pyoderma gangrenosum (PG). A biopsy confirmed the diagnosis. Corticosteroid therapy was started and symptoms improved. This work highlights the association between PG and pyogenic polyarthritis, a combination of pathologies that is rarely reported in the literature.
