摘      要：Background: The spindle cell lipoma is a rare benign tumor that originated from subcutaneous adipose tissue. It is a slow growing lesion and may become voluminous causing the patient an aesthetic disfigure. The diagnosis is made by the histological examination combined with immunohistochemical analysis. Radiological features present a variety of description because of the proportions difference of spindle cell lipoma components, but imaging is useful to determine the mass extents. The treatment of this kind of benign tumors is surgery which must be completed without need for other therapy. Aim: This case report highlights the exceptional location of spindle cell lipoma in the soft tissues of the parotid-masseter lodge, which may raise differential diagnosis problems with a primary parotid gland tumor. Case Presentation: A 58-year-old man, with no medical history, was presenting a swelling of the parotid region, growing progressively for 6 years, without other associated sign. The patient benefited from a careful physical examination. A computed tomography and magnetic resonance imaging were carried out. Clinical and radiological findings were suggesting a benign tumor occupying the left parotid-masseter lodge. The patient went through a surgical excision of the tumor. Histological and immunohistochemical features revealed a classic shape of spindle cell lipoma. After one year of follow-up, we notice a good recovery without local recurrence. Conclusion: Surgeons and pathologists have to keep in mind the possible development of spindle cell lipoma in any subcutaneous site even if unusual one.
