Lipoma Of Neck Research Articles

Pulmonary embolism and deep jugular venous thrombosis resulting from compression by a lipoma

Lipomas usually extend in subcutaneous tissues and rarely may be compressive. We report a case of neck lipoma resulting in jugular vein thrombosis and pulmonary embolism in a patient treated by clozapine. Clozpine may be considered an associated risk factor for thrombosis. This case suggests that performing a regional evaluation may be particularly important when thrombophlebitis occurs.

Lipomas of the head and neck: presentation variability and diagnostic work-up

Head and neck lipomas have seldom drawn attention in the literature, except in isolated case reports. This study aimed to assess the presentation variability of head and neck lipomas as well as the relative importance and efficiency of pre-operative diagnostic methods used. A retrospective review was undertaken of medical records and imaging studies of 24 patients with histopathologically proven head and neck lipomas, over a three-year period. The 24 patients had 26 lipomas. Men predominated (62.5 per cent). The posterior subcutaneous neck was the most common site. Three patients had deep lipomas affecting the hypopharynx, larynx and parotid gland; all were correctly diagnosed pre-operatively. Computed tomography (CT) scan with specific radiodensity recording was the preferred pre-operative investigation. Lipomas should be considered in the differential diagnosis of soft-tissue head and neck masses even in rare locations. A CT or magnetic resonance imaging scan can correctly diagnose a lipoma pre-operatively, thereby allowing better treatment planning.

Lipoma with dumb-bell extradural extension through the intervertebral foramen into the spinal canal

The authors present the case of a 60-year-old woman with a neck lipoma that developed dumb-bell extradural extension, causing radiculopathy. To the best of the authors' knowledge, this is the first report of a lipoma originating in the neck with dumb-bell extradural extension through the intervertebral foramen and into the spinal canal. The lipoma was first excised from the foramen via a posterior approach to allow decompression of the nerve roots. The remaining lipomatous tissue was then resected via an anterior approach to avoid the region around the vertebral artery.

A clinicopathological study of lipomas of the head and neck

Background: Lipoma of the head and neck region are fairly common. Methods: This twelve year retrospective study evaluated thirty-nine cases of head and neck lipomas in Nigerians. Results: They constituted 14.4% of benign tumours of the head and neck region and 17.6% of total body lipomas seen within the study period. There were two peaks in the age distribution with patients in the fifth and seventh decades of life recording the highest number of cases. More males were affected with a male-female ratio of 2:1. Most cases (33.3%) were seen in the neck, followed by the scalp (23.1%). Only one intra oral case presenting on the tongue was recorded. The two patients with multiple lipomas were negative for associated systemic disease. Two histological variants were seen (conventional and fibrolipoma). Conclusion: Tumours of adipose tissue are common head and neck neoplasms. While conventional lipomas are the commonest histological variants, the diagnosis of these lesions may be arrived at from clinical presentations supplemented with histological examinations. Treatment by surgical excision (lipectomy) produces satisfactory results. (Nig J Surg Res 2003; 5; 12 – 17) Key words: Head and neck, lipomas

頚部腫りゅう切除後に副神経麻ひを生じた３例

Three cases of accessory nerve injury after excision of the neck tumor were reported. Characteristic complains of these patients are shoulder pain, atrophy of the trapezius, and weakness of shoulder abduction.A 59-year-old female visited our hospital 7 months after excision of the right neck lipoma. She noticed pain, atrophy, weakness and inability to horizontally abduct the shoulder. Intraoperatively, the accessory nerve was found to be buried in the scar. Neurolysis was performed because muscle twitch was elicited by electrostimulation. She could horizontally abduct the shoulder 3 weeks after neurolysis and complete recovery was seen after 3 years and 3 months.A 27-year-old male was referred to our hospital, 2 months after excision of the right neck lymphnode. Intraoperative findings revealed a neuroma in-continuity of the accessory nerve. 7 months after resection of the neuroma and epineural repair, complete recovery was seen.A 36-year-old male visited our hospital, 2 months after excision of the right neck lymphnode. The accessory nerve was buried in the scar and one of three funiculi was tied. Resection of neuroma and funicular repair were performed in the funiculus and neurolysis was carried out in the other. Six months after surgery, muscle strength was recovered, but trapezius atrophy remained.

Lipomas of the head and neck in children

Head and neck lipomas in the pediatric population are rarely described in the literature. Two patients who presented to the Hospital for Sick Children with rapidly enlarging head and neck lipomas are presented. Radiographic imaging, including CT and MRI, as well as fine needle aspiration implicated a lipoma as the probable diagnosis. Both patients were treated by surgical excision. The clinical behavior, diagnostic work-up and treatment of these rare lesions are the focus of this study.
