Aggressive angiomyxoma (AA) is a rare, benign, mesenchymal tumour of the pelvis and perineum. It usually occurs in females at reproductive age. However, rare cases have been reported in male children. We present the first case of aggressive angiomyxoma in the penis of a 9-month-old Somalian boy. The infant presented with large, nodular penile mass. The diagnosis was confirmed following complete surgical removal and histopathological examination. Over 6-month follow-up period, no recurrence was noticed. Therefore, we recommend complete surgical removal of the mass with wide safety margin and long-term follow-up is recommended for the cases of AA.
