Lymphomas of the oral cavity represent 5% of all lymphomas. They usually occur in immunocompromised patients. Lymphoma arising within a single bone, without visceral or lymph node involvement, is known as primary intraosseous lymphoma. It is a rare condition and constitutes 3.1% of malignant bone tumors and 5% of extranodal lymphomas. Primary lymphoma of the jaw is seldom seen and it is often misdiagnosed. Clinically, the manifestations are usually similar to an odontogenic tumor, cyst, or infection. Radiographically it appears as a radiolucent area that may mimic endodontic lesion, periodontal pathology, or odontogenic cyst or tumor. The initial presentation is commonly followed by multiple unnecessary extractions and/or root canal treatments. We present five cases of rare primary lymphoma of the maxillofacial complex, four of them intraosseous.
口腔淋巴瘤占所有淋巴瘤的5%。它们通常发生在免疫功能低下的患者中。起源于单一骨骼且无内脏或淋巴结受累的淋巴瘤称为原发性骨内淋巴瘤。这是一种罕见的疾病，占恶性骨肿瘤的3.1%，占结外淋巴瘤的5%。颌骨原发性淋巴瘤很少见，且常被误诊。临床上，其表现通常类似于牙源性肿瘤、囊肿或感染。影像学上，它表现为一个透射区，可能类似牙髓病变、牙周病变或牙源性囊肿或肿瘤。最初的表现通常会导致多次不必要的拔牙和/或根管治疗。我们报告5例罕见的颌面复合体原发性淋巴瘤病例，其中4例为骨内型。
