Soft tissue paraspinal inflammatory malignant fibrous histiocytoma presenting as a lumbar abscess

Emmanouil Liarmakopoulos et al. Case Rep Oncol. 2011.

Abstract

The rarest subtype of malignant fibrous histiocytoma (MFH) is the inflammatory type, which due to its peculiar clinical presentation may mimic an infectious process such as an abscess. The rarity of this disease and the unique features of its presentation may mislead the surgeon with consequent catastrophic results for the patient. In this study, a case report of a 65-year-old female patient with a soft-tissue inflammatory MFH presenting as a lumbar abscess and a review of the current literature are presented.

Keywords: Malignant fibrous histiocytoma, inflammatory type; Soft-tissue sarcoma.
