To report a case of intramuscular haemangioma (IMH) with a rare presentation in the mylohyoid, with emphasis on the clinical appearance, and histologic characteristics of the lesion.
Case report and review of the literature.
Neck swellings can often present a diagnostic dilemma, with a wide preoperative differential diagnosis. IMH are rare benign haemangiomas occurring within the skeletal muscle. They account for approximately 1% of all haemangiomas. These are uncommon in the head and neck region and occur most frequently in the trunk and extremities. In the head and neck, masseter and trapezius are the most common sites involved. Intramuscular haemangioma is seldom diagnosed preoperatively, perhaps due to unfamiliarity with this uncommon lesion and nonspecific clinical findings.
报告一例罕见的颏舌骨肌内海绵状血管瘤（IMH）病例，重点阐述该病变的临床表现及组织学特征。
病例报告及文献复习。
颈部肿块常常会带来诊断难题，术前鉴别诊断范围广泛。IMH是发生于骨骼肌内的罕见良性血管瘤。它们约占所有血管瘤的1%。在头颈部区域并不常见，最常发生于躯干和四肢。在头颈部，咬肌和斜方肌是最常受累的部位。肌内血管瘤术前很少被诊断出来，可能是由于对这种罕见病变不熟悉以及临床表现不具有特异性。
