BACKGROUND
Melanotic neuroectodermal tumor of infancy (MNTI) is a rare clinically benign, pigmented, tumor of neural crest origin which commonly occurs in the maxilla. It is a rare tumor that may pose difficulty in differentiating from other malignant round cell tumors.
CASE PRESENTATION
A 5-month-old Ethiopian infant presented with a mass on his forehead. A wide excision of the lesion was done and subjected to histopathologic evaluation. The histologic and immunohistochemistry for synaptophysin studies confirmed that the infant was having MNTI. The patient was followed and there was no sign of recurrence at the 6th and 9th months of follow-up.
CONCLUSION
MNTI should be considered as a differential diagnosis for tumors occurring in the head region in infants and prolonged follow-up may be needed to check for possible recurrence of the tumor.
背景
婴儿黑色素神经外胚层肿瘤（MNTI）是一种罕见的临床良性、色素性、神经嵴起源的肿瘤，常见于上颌骨。它是一种罕见的肿瘤，可能难以与其他恶性圆形细胞肿瘤区分。
病例介绍
一名 5 个月大的埃塞俄比亚婴儿额头上有一个肿块。对病变进行了广泛切除，并进行了组织病理学评估。突触素的组织学和免疫组织化学研究证实该婴儿患有 MNTI。对患者进行了随访，在随访的第 6 个月和第 9 个月没有发现复发的迹象。
结论
MNTI 应被视为婴儿头颈部肿瘤的鉴别诊断，可能需要进行长期随访以检查肿瘤是否有复发的可能。
