Erythema nodosum leprosum (ENL), characterized by erythematous subcutaneous nodules with multiorgan involvement and systemic manifestations such as neuritis, arthritis, and orchitis, affects approximately 50 % of patients with lepromatous leprosy (LL). It has also been associated with testicular atrophy and adult-onset hypogonadism, but testicular nodules have rarely been reported. We present the case of a 35-year-old male patient with biopsy confirmed LL who completed multidrug therapy and presented for follow-up with a complaint of testicular tenderness. His disease course had been complicated by ENL and polyneuritis. At the time, physical examination revealed a palpable tender nodule in the left testicle. Testicular ultrasound and magnetic resonance imaging showed bilateral intratesticular masses, of which the differential diagnosis included malignancy and inflammatory or postinfectious granulomatous process. Laboratory workup, testicular malignancy markers, and hormone levels were within normal limits. In view of the patient's underlying condition and after Urology evaluation, a diagnosis of granulomatous process was favored. The patient completed a prednisone taper followed by a 3-day prednisone pulse and weekly methotrexate, with sequential testicular ultrasounds to monitor response. After a year of close follow-up and slow tapering of methotrexate, the patient achieved complete resolution of the left intratesticular mass and decrease in size of the contralateral mass, evidenced by both physical examination and imaging. This case highlights the importance of a high index of suspicion in patients with LL and ENL who present with testicular nodules, as awareness of testicular involvement in this population is imperative to avoid life altering procedures such as orchiectomy.
