Management of giant intermuscular lipoma of hips: A case report and review of literature.

Intermuscular lipomas are rare soft tissue tumors of mesenchymal origin. They are closely correlated with other benign and malign mesenchymal tumors in clinical presentation and imaging, causing problems in diagnosis and treatment. This study examined a rare giant intermuscular lipoma of the hip and its management, allowing clinicians to become familiar with this lesion. Furthermore, the clinical data of 13 patients with pathologically confirmed giant intermuscular lipomas (1 case treated by the authors, the remaining 12 cases reported in the Chinese literature during the period from January, 1992 to May, 2012) were also reviewed and analyzed. Based on the review, intermuscular lipomas were found to be more common in males and usually presented with an asymptomatic mass, with an average patient age of 39.7 years (range, 11-70), while symptom duration was between 1 month and 10 years. The most common tumor origin sites were the thigh and forearm and the option of treatment was surgical excision. The present study showed that it is crucial for the surgeon to consider infiltrating lipomas when dealing with deep soft tissue masses, while complete removal of the lesion was vital to avoid recurrence.
