The 3-year-old proband exhibited systemic pustules leading to a GPP diagnosis, while his 6-year-old sister developed nail ulcers and subungual pustules characteristic of ACH. Despite standard treatments, their conditions were refractory. Genetic analysis revealed a homozygous splice variant c.115+6 T>C, with heterozygous parents. This case underscores the role of IL36RN mutations in pustular psoriasis and supports ACH as a localized form of the disease. The distinct subtypes in siblings with identical mutations suggest a complex pathogenesis influenced by additional factors. Our findings highlight the importance of genetic testing in pustular psoriasis and warrant further investigation into the phenotypic variability of IL36RN-related disease.Keywords: Acrodermatitis Continua of Hallopeau, generalised pustular psoriasis, IL36RN gene mutations |
