A 28-year-old lady presented with recurrent episodes of painful, pus-filled lesions over fingertips resulting onychodystrophy, anonychia, and mild tapering of fingers. Based on history and examination findings [Figure 1], a diagnosis of Acrodermatitis continua of Hallopeau was made. It is a chronic sterile pustular eruption of tips of fingers and toes with slow proximal extension. The condition is often refractory to treatment and may evolve into generalized pustular psoriasis.[1]
