Pseudoxanthoma elasticum in childhood in patient with β-thalassaemia.

Pseudoxanthoma elasticum (PXE) is a rare genetic disorder characterised by elastic tissue alterations and caused by mutations in a single gene, ABCC6, on chromosome 16p that includes manifestations that are predominantly cutaneous, ocular and cardiovascular. PXE-like lesions in association with β-thalassemia have previously been reported in the literature in patients with β-thalassaemia intermediate and major, being clinically indistinguishable from classic PXE. The case is presented of a 10-year-old boy with β-thalassaemia minor and characteristic lesions of PXE. It is worth noting the benefit of multimodal imaging in the diagnosis and monitoring of the lesions.
