Subcorneal pustular dermatosis: Eleven years of experience in a national reference center. Report of cases

Subcorneal pustular dermatosis is a rare and little known dermatosis. The objective of this paper is to describe the experience of the authors in the diagnosis and treatment of a group of Colombian patients with this disea-se. Six cases are presented, diagnosed between 2010 and 2021. All of the patients had long-standing lesions (on average 5 years) and the most affected areas were the thorax (83%), the armpits (66%), and the proximal third of the extremities (50%). The most common lesions were pustules (83%), papules (83%), and erythematous-crusted plaques with circinated edges (50%); typical flaccid pustules were only observed in two cases (33%). In conclusion, the timely diagnosis of subcorneal pustular dermatosis requires recognition of a wide spectrum of clinical presentations, as well as adequate clinicopathological correlation.
