摘要：

黏膜相关淋巴组织（mucosa-associated lymphoid tissue，MALT）淋巴瘤是一种生长缓慢、无痛的恶性肿瘤，该病好发于胃肠道，发生于头颈部者相对少见。在头颈部病例中，以腮腺受累较为常见，而原发于舌下腺的MALT淋巴瘤报道较少，且该病易与舌下腺良性肿瘤混淆。本文报道1例原发于舌下腺的MALT淋巴瘤，并结合相关文献，对其临床表现、病因及治疗进行讨论。

Abstract:

Mucosa-associated lymphoid tissue (MALT) lymphoma is an indolent and painless malignant tumor that most commonly occurs in the gastrointestinal tract, but it is relatively rare in the head and neck region. Among head and neck cases, involvement of the parotid gland is more common, while primary sublingual gland involvement is rarely reported and can be easily confused with benign sublingual gland tumors. This article reports a case of MALT lymphoma primarily originating from the sublingual gland and discusses its clinical manifestations, etiology, and treatment through a review of relevant literature.

Key words: mucosa-associated lymphoid tissue lymphoma, oral and maxillofacial tumors, sublingual gland
