Its presentation could simulate a sarcoma. The large size of the tumor and the submuscular location, bone erosion, and compression of the CNS were unusual in this rare subtype of benign adipose tumor. We report a patient with an expanding fat density. The relative rarity of such a tumor in this location, especially in the chondrous. The lesion usually presents in male patients between the age of 40 to 60, and is located in the subcutaneous layer of the posterior trunk, shoulder and posterior neck 1. Spindle cell lipoma (SCL) is a rare mediastinal tumor hard to be differentiated from myxoid liposarcoma. led to the diagnosis of a spindle cell lipoma with chondrous metaplasia. Spindle cell lipomas commonly grow around the upper back and neck but can. Histological assessment revealed numerous fat cells with spindle cells secreting collagen. Spindle cell lipoma is an uncommon variant of lipoma, characterized by mature adipocytes and small uniform spindle cells. A spindle cell lipoma is a non-cancerous tumour made up of fat and spindle cells. To our knowledge, the presence of such a tumor in the. The tumor, which had initially developed under the muscles of the posterior neck, was totally resected. Spindle cell lipomas are usually located in the subcu- taneous tissue ofthe back, shoulders, and neck. The lesion was well delimited, and contrast enhancement was intense and heterogeneous. Computed tomography and MR imaging studies revealed a voluminous mass extending to the upper cervical canal and posterior cranial fossa and eroding the neighboring bones. He also had a posterior neck tumefaction, which had been known about for a long time. This 61-year-old man presented with an increased left cerebellar syndrome and headaches. It usually occurs as a solitary subcutaneous well-circumscribed lesion in the posterior neck or shoulders of adult men. Spindle cell lipoma typically occurs in the posterior neck, shoulder and back, and less commonly in a wide range of other locations. We hypothesized that SCL in women have a more varied presentation. In general, there is a frequent tendency to restrict the diagnosis to this specific clinical scenario and a hesitancy to diagnose SCL in women. Spindle cell lipoma is an extremely rare variant of benign lipoma. Spindle cell lipomas (SCL) are typically tumors of the upper back/neck (shawl region) of men (80 to 90).
The authors describe the first case of spindle cell lipoma of the posterior neck invading the upper cervical spinal canal and the posterior cranial fossa.
