INTRODUCTION
Pleomorphic adenoma is a rare benign salivary gland neoplasm in children, which can be treated by simple excision. This tumor is rarely included in the differential diagnosis of solid submandibular masses in children. In the neonates, congenital pleomorphic adenoma usually presents in the nasopharynx. Surgical excision is the treatment of choice and recurrence is not expected. We report what appears to be the first case of congenital pleomorphic adenoma in the submandibular region in a one-day-old newborn.
CASE REPORT
The case of a one-day-old term baby is presented with a 5x2 cm left submandibualr mass with extension to the oral cavity. The mass was hard and non-mobile. During Ultrasonography and Contrast-enhanced Computed Tomography (CT) scan, the mass was solid with a heterogeneous internal structure. The tumor was completely excised and proved to be a pleomorphic adenoma during histopathological examination.
CONCLUSION
Congenital pleomorphic adenoma rarely occurs in the nasopharynx and is treated by surgical excision. Our case is unique because the congenital pleomorphic adenoma is located in the submandibular gland of a newborn.
引言
多形性腺瘤是儿童罕见的良性涎腺肿瘤，可通过单纯切除进行治疗。该肿瘤很少被纳入儿童颌下实性肿块的鉴别诊断中。在新生儿中，先天性多形性腺瘤通常出现在鼻咽部。手术切除是首选治疗方法，预计不会复发。我们报告了一例似乎是一日龄新生儿颌下区先天性多形性腺瘤的首例病例。
病例报告
一名一日龄足月儿，左侧颌下有一个5×2厘米的肿块，延伸至口腔。肿块质地硬，活动度差。在超声检查和增强计算机断层扫描（CT）中，肿块为实性，内部结构不均匀。肿瘤被完全切除，组织病理学检查证实为多形性腺瘤。
结论
先天性多形性腺瘤很少发生在鼻咽部，通过手术切除进行治疗。我们的病例很独特，因为先天性多形性腺瘤位于新生儿的颌下腺。
