Bilateral iliopsoas haemophilic "soft tissue pseudotumours": A case report.

Haemophilic soft tissue pseudotumour is one of the rarest complications of haemophilia that caused by repetitive bleeding resulting in an encapsulated mass of clotted blood and necrotic tissue. Soft tissue pseudotumour may not only cause flexion contracture but also chronic pain and femoral nerve compression that cause severe disability. Thus, surgical excision is the treatment of choice. It should only be carried out in a major haemophilic center by an integrated multidisciplinary surgical team.
