BARRETO SPANDONARI, Claudia et al. Lucio´s phenomenon. About a case. An. Fac. Cienc. Méd. (Asunción) [online]. 2022, vol.55, n.2, pp.88-91. ISSN 1816-8949.  https://doi.org/10.18004/anales/2021.055.02.88.

Lucio's phenomenon is a rare and severe reactional state mediated by immune complexes that is commonly seen in cases of diffuse lepromatous leprosy. In Paraguay, it represents approximately 2% of leprosy diagnosed cases, mainly as a debut of the disease. It manifests with macule-type skin lesions and polygonal purpuric plaques, generally without visceral involvement. The diagnosis is confirmed by the histopathological study and it is essential to consider differential diagnosis such as vasculitis of other etiologies.
