INFANTILE FIBROMATOSIS OF THE SCROTUM: A CASE REPORT

Infantile fibromatosis is a process that is difficult to differentiate from fibrosarcoma. It is common in neonates and infants and usually arises from head and neck. Only rarely it has been reported to involve the external genitalia or scrotum. We report a case of an eight-month old infant who presented with a painless scrotal mass that has been slowly enlarging for the previous 3months. Gray-scale sonography demonstrated a heterogeneously echogenic paratesticular mass in right hemiscrotum. Histologic examination of the excised mass revealed infantile fibromatosis of the scrotum. Sonographic appearance of this entity has not been described previously.
