Abstract
Until now, leprosy remains a problem and challenge in the world because it can cause disability and morbidity in affected individuals, including problems due to the emergence of type 2 lepra reaction or erythema nodosum leprosum (ENL). The clinical picture of ENL can appear in an atypical and severe form, called ENL necroticans (ENN), which becomes a problem in diagnosis and therapy. We report a 17-year-old female with lepromatous leprosy and ENN who received therapy in the form of a combination of steroids and methotrexate. Four months after consuming this therapy, the ulcers on the patient's body improved, leaving atrophic and hypertrophic scars. ENN's unusual clinical presentation poses diagnostic difficulties in that its appearance does not follow the typical patterns, making it challenging to identify correctly. Furthermore, managing cases of ENN may necessitate supplementary treatment beyond steroids alone.
