Anterior abdominal wall ischaemia in association with multiple myeloma

This article reports a case of anterior abdominal wall ischaemia in a 52-year-old woman with an underlying diagnosis of multiple myeloma. The patient underwent emergency surgical debridement of the affected area. The abdominal wall was subsequently resurfaced with a split skin graft. Histological examination of the excised tissue revealed the cause to be a paraneoplastic vasculopathy with immunoglobulin light chain (lambda-type) deposition in the blood vessels of her abdominal apron secondary to multiple myeloma. Literature review has failed to show previous reports of this condition. The differential diagnosis and aetiology are discussed.
