Abstract

Spindle cell lipoma (SCL) is a subtype of lipoma classified by Enzinger et al. in 1975. It is a benign tumor commonly found in the subcutaneous tissue of the shoulder, back, and posterior neck in middle-aged men. This report describes a rare case of low-fat type SCL in the pterygomandibular space. A 33-year-old man was referred to the department for further examination and treatment of a radiolucent area of the left mandibular ramus incidentally detected on a panoramic radiograph taken by a general dentist. Computed tomography and magnetic resonance imaging showed a 50 mm mass with apparent continuity with the inferior alveolar neurovascular bundle in the pterygomandibular space. An incisional biopsy prompted a provisional diagnosis of neurofibroma, and the whole tumor was excised under general anesthesia. Histopathologically, the tumor was found to consist of spindle-shaped cells, adipocytes, and collagen fibers, resulting in a final diagnosis of SCL. There has been no evidence of recurrence more than 5 years postoperatively.
翼状下颌间隙梭形细胞脂肪瘤1例
梭形细胞脂肪瘤(Spindle cell lipoma, SCL)是1975年Enzinger等人分类的一种脂肪瘤亚型。它是一种良性肿瘤,常见于中年男性肩部、背部和后颈部的皮下组织。本文报告一例罕见的翼状下颌间隙低脂型SCL。一名33岁男子被转介到科室进一步检查和治疗在全景x光片上偶然发现的左侧下颌骨分支的透光区域。计算机断层扫描和磁共振成像显示一个50毫米的肿块,与翼下颌间隙的下肺泡神经血管束有明显的连续性。切口活检提示神经纤维瘤的临时诊断,并在全身麻醉下切除整个肿瘤。组织病理学发现肿瘤由梭形细胞、脂肪细胞和胶原纤维组成,最终诊断为SCL。术后5年以上无复发迹象。
