Melanotic Neuroectodermal Tumor of Infancy Presenting with Fast Growing Scrotal Swelling: A Case Report and Literature Review

Abstract

Testicular melanotic neuroectodermal tumor of infancy (MNTI) is extremely rare, with 2 cases reported in the literature. Its rarity, 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 one 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.
