Lucio's phenomenon in a patient with leprosy on Aruba

Background: Lucio's phenomenon is a rare leprosy reaction characterised by bizarrely-shaped, purpuric skin lesions and ulceration. It occurs in diffuse lepromatous leprosy and it is mainly reported in patients from Mexico and the Caribbean.

Methods: We describe the case of a 90-year-old Aruban man with recurrent leg ulcers and flexion contractures of the lower extremities. Occurrence of Lucio's phenomenon led to a diagnosis of diffuse lepromatous leprosy. Presence of Mycobacterium leprae was demonstrated in skin, bone marrow and lymph nodes.

Conclusions: Lucio's phenomenon led to a diagnosis of leprosy. Leprosy is still endemic in Aruba.
