| Abstract | dc.description.abstract | A 44-year-old man, previously healthy, consulted for a three-month history of asymmetrical
polyarthralgia with inflammatory features involving. small mod large joints. A few days later, he
developed erythema covered by pustules in the nail folds and progressive degeneration of the nail plate
of the left thumb, with severe functional limitation. The physical exam showed well-defined
erythematous scaly and pustular plaques in the first and third fingers of the left hand, with severe
onychodystrophy, which was a key aspect in the diagnosis of acrodermatitis continua of Hallopeau.
Other signs of the psoriatic spectrum were observed: erythematous patches of the scrotum, erythematous
scaly plaques with hemorrhagic crusts on both knees, and dactylitis. The diagnosis of inverse psoriasis,
plaque psoriasis, and pustular psoriasis, respectively, were confirmed by histopathology and, with the
CASPAR critetia, psoriatic arthritis. This case is of particular dermatological interest due 10 the variety
of psoriatic manifestations recognized in a single patient and because of he poorly described association
between acrodermatitis continua of Hallopeau with psoriatic arthritis. | es_ES |
