Acute stridor caused by a previously asymptomatic large oropharyngeal spindle cell lipoma

Lipomas of the larynx, oropharynx and hypopharynx are rare, accounting for approximately 1% of benign laryngeal neoplasms. Spindle cell lipoma is a rarer histological variant characterised by mature adipocytes mixed with collagen-forming spindle cells. We present an unusual case of a 62-year-old lady who acutely presented to the emergency department with a large spindle cell lipoma arising from the vallecula. This lipoma was causing intermittent stridor unless traction was applied to it. Despite the size of the lesion, she had been completely asymptomatic prior to this single episode. To our knowledge, only one previous case of a spindle cell lipoma has been reported as specifically arising from the vallecula. This case also appears to be the largest reported from the oropharynx (17 cm length, 4 cm width). The tumour was completely removed endoscopically and the patient made an excellent recovery, returning home 3 days post-operatively. The histology, management and follow up of these lipomas are discussed. (c) 2007 Elsevier Ireland Ltd. All rights reserved.
