Dermal spindle cell lipoma of the posterior neck: CT and MR findings

ABSTRACT Spindle Cell Lipoma (SCL) is an uncommon benign tumor of adipose tissue that is usually super􀃶cially located in the posterior neck, back and shoulder region. We report a rare case of SCL in a 39 years old male presenting as neck swelling with c/o stridor and dysphagia. The contrast enhanced computed tomographic scan of neck showed an external and internal part of the swelling traversing through the thyrohyoid membrane suggestive of Mixed Pyolaryngocele. The tumor was excised by a trans-cervical approach but the post operative histopathology was found to be spindle cell Lipoma. We report this case due to its atypical presentation and location.

Pleomorphic lipoma is a rare neoplasm that is considered as a variant of spindle cell lipoma. It predominantly occurs in the dermis or subcutis of the posterior neck, upper back, and shoulders. Pleomorphic lipoma may clinically present as a slow-growing and well-circumscribed subcutaneous mass. Though it is a benign tumour it may contain atypical cells for which it may mimick sarcoma or other malignant soft tissue tumours. So histopathological diagnosis is vital for preventing unnecessary surgery. Here we report a case of a pleomorphic lipoma on upper back in a 55yr old patient.

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. Spindle cell lipoma is an extremely rare variant of benign lipoma. It usually occurs as a solitary subcutaneous well-circumscribed lesion in the posterior neck or shoulders of adult men. Local aggressiveness is unusual. This 61-year-old man presented with an increased left cerebellar syndrome and headaches. He also had a posterior neck tumefaction, which had been known about for a long time. 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. The lesion was well delimited, and contrast enhancement was intense and heterogeneous. The tumor, which had initially developed under the muscles of the posterior neck, was totally resected. Histological assessment revealed numerous fat cells with spindle cells secreting collagen. 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. Its presentation could simulate a sarcoma.

Combined Feature

The author describes a benign soft tissue tumor that could be easily mistaken for sarcoma. It represents a combined feature of solitary fibrous tumor and spindle cell lipoma. The clinical presentation, diagnosis, and management of this lesion are discussed. It highlights the importance of proper diagnosis to prevent unnecessary and ineffective treatment by clinicians as the complete excision of this lesion is the treatment of choice and recurrence is very unlikely. It is believed that this case is the first reported case of dendritic myxofibrolipoma occurring in the lower lip mucosa in an Omani patient.
