Abstract

Testicular melanotic neuroectodermal tumor of infancy (MNTI) is extremely rare, with 2 cases reported in the literature. Its rarity and rapid and infiltrative growth pattern pose a diagnostic challenge. A previously healthy 3-month-old male, presented with a history of worsening left hemiscrotal swelling for 1 week. An outside ultrasound was suggestive of testicular torsion. Left orchiectomy demonstrated a mass occupying almost entire testicle with a variegated cut surface, with areas of pigmentation, necrosis, and hemorrhage. Histological examination confirmed MNTI of the testis and epididymis. MNTI should be included in differential diagnosis in infants presenting with fast-growing scrotal swelling.
