A 39-year-old man presented with a two-month history of painful erythematous-violet nodular lesions on his trunk and lower limbs, accompanied by arthralgia in the small joints of the hands, wrists, ankles, and elbows, with morning stiffness for about an hour that improved with movement. He reported having experiencing similar, self-limited episodes for the last year and a half, each episode lasting for approximately five days and ac companied by significant weight loss. On physical examination, the patient was malnourished, with lamellar desquamation and mobile nodules of approximately 3 cm, together with erythema tous-violet lesions on the anterior surface of thighs, just above the knees bilaterally and at the left thoracoabdominal junction. He also had gross thickening of the fibular and ulnar nerves bilater ally, as well as of the right greater auricular nerve (Figure 1). The diagnosis of lepromatous leprosy was confirmed by skin biopsy. We assessed the peripheral nerves by ultrasound (Figure 2).
