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.
期刊介绍:
Oral and Maxillofacial Surgery Cases is a surgical journal dedicated to publishing case reports and case series only which must be original, educational, rare conditions or findings, or clinically interesting to an international audience of surgeons and clinicians. Case series can be prospective or retrospective and examine the outcomes of management or mechanisms in more than one patient. Case reports may include new or modified methodology and treatment, uncommon findings, and mechanisms. All case reports and case series will be peer reviewed for acceptance for publication in the Journal.
