Malignant fibrous histiocytomas (MFH) belong to the most frequent soft tissue tumours in adults and have to be discriminated from other tumours with similar morphology. Various tumour markers aid the differential diagnosis. Twenty cases of MFH were studied immunohistochemically using antibodies to vimentin, TPA, desmin, lysozyme, alpha 1-antitrypsin, alpha 1-antichymotrypsin, S-100 protein, neurone-specific enolase (NSE), laminin, fibronectin and ferritin. Vimentin and lysozyme were found in the tumour cells of all, alpha 1-antitrypsin of 18, alpha 1-antichymotrypsin of 19, fibronectin of 16 and ferritin of 12 cases. Antibodies of TPA, desmin, S-100 protein, NSE and laminin did not reveal positive immunoreactivity. Exclusion of spindle-cell carcinoma can be made by positive vimentin and negative TPA reactivity, of melanoma by negative S-100 reactivity, and of leio- and rhabdomyosarcoma by lack of desmin immunoreactivity. Schwannomas contain S-100 protein, but lack lysozyme, alpha 1-antitrypsin, alpha 1-antichymotrypsin and fibronectin. Pleomorphic liposarcomas cannot be distinguished from MFH on the basis of immunohistochemical staining. Vimentin, alpha 1-antitrypsin, alpha 1-antichymotrypsin and fibronectin can, therefore, be regarded as useful markers in the differential diagnosis of MFH.

We describe a lupus flare in a 59-year-old woman who presented with pancytopenia, nephritis, severe renal dysfunction and marked hyperferritinemia. The course of the disease was further complicated by an iron-laden, intraspinal ancient schwannoma that compressed the cervical cord mimicking a lupus-related myelopathy and was removed surgically. Treatment with mycophenolate mofetil (MMF) and prednisone induced a gradual decline in levels of serum ferritin with a concomitant improvement in renal function and reduction of proteinuria. Serum ferritin may be a useful marker of the response to treatment with MMF in renal lupus.
