Acrodermatitis continua of Hallopeau (ACH) is a rare, chronic, and recalcitrant inflammatory disorder classified as a localized variant of pustular psoriasis. Patients usually present with relapsing episodes of subungual pustules, nail dystrophy, and scaling. We report a case of ACH in a 32-year-old female, which developed following a nail infection and exacerbated during pregnancy, with no medication for 2 years. She presented at the clinic with severe manifestations of anonychia and multiple bone resorption on the distal phalanges. The patient was started on topical medication of combination corticosteroid and vitamin D analogue and oral methotrexate initially at l0mg/week then increased to 15mg/week due to poor response. Despite compliance to medications and avoidance of possible irritants, the patient still had relapse of pustules on the nails.

Several treatment options for ACH are available such as topical steroids, vitamin D analogue, systemic biologics, and non-biologics such as methotrexate and cyclosporine. However, systemic biologics are considered the most efficacious for ACH but financial constraints often limit their use in resource-poor settings.
