It has both Langerhans and non-Langerhans cell histiocytosis immunophenotypic features. We described a 45-year-old man with a 2 years history of multiple yellow-brown papules and a few red nodules on his trunk and extremities. No internal involvement was detected first and after 8 months. As his lesions were asymptomatic and sparse, he didn't receive any treatment. He will be followed at regular intervals. https://acta.tums.ac.ir/index.php/acta/article/view/4546 https://acta.tums.ac.ir/index.php/acta/article/download/4546/4650
