The clinicopathological features of malignant cells are sometimes modified by autologous cytokine production. Inflammatory fibrous histiocytoma (IFH) is characterised by leukocyte infiltration and is a variant of malignant fibrous histiocytoma (MFH). We demonstrated that three MFH cell lines (MF-1, MF-3, and MF-4) have the potential to promote neutrophil chemotaxis and to express mRNA for the cytokines, granulocyte-macrophage colony stimulating factor (GM-CSF) and/or interleukin 8/neutrophil attractant/activation protein 1 (IL-8/NAP-1), both with and without interleukin 1 beta (IL-1 beta) stimulation. MF-1 cells showed the spontaneous production of neutrophil chemotactic activity and the expression of both of GM-CSF and IL-8/NAP-1 mRNA, which was enhanced by exogenous IL-1 beta. In contrast, MF-3 cells showed the expression of GM-CSF and IL-8/NAP-1 mRNA with IL-1 beta stimulation but not without it, and MF-4 cells expressed only IL-8/NAP-1 mRNA when stimulated with IL-1 beta (time- and dose-dependent expression). These findings suggest that neutrophil chemotactic cytokines derived from IFH cells might be responsible for the prominent infiltration of neutrophils in this disease.

We present a case of malignant fibrous histiocytoma accompanied by prolonged spiking fevers, which disappeared after tumor resection. Sarcoma with fever as a primary symptom is rare. Furthermore, in this case, fever was closely related to the clinical course of the tumor. In order to detect possible production of febriferous substance(s), we used blood and tumor tissue samples to investigate nine candidate cytokines possibly responsible for the fever. Expression of IL-8 mRNA was detected in preoperative peripheral blood mononuclear cells by RT-PCR. Expressions of IL-6, IL-8, IFN-gamma and TNF-alpha mRNAs were also detected in tumor tissue, while IL-1alpha, IL-1beta, IL-2, IL-4 and COX-2 mRNAs were not. We suspected IL-8 to be a causative factor, and examined its localization by immunohistochemical staining, paraffin sections of tumor tissue stained positive for IL-8. Since infiltrating mononuclear cells were positive for IL-8, this may explain the tumor-associated fever. This case involves intratumoral production of IL-8 as a causative factor, and IL-6, IL-8, IFN-gamma and TNF-alpha cytokine production might have resulted from stimulation with a substance(s) derived from tumor tissue, since the fever disappeared postoperatively. To date the patient is alive and in good health for 7 years and 2 months since the surgery.

Sarcomatoid variant of anaplastic large cell lymphoma (ALCL) is one of the rarest histologic variants of ALCL that consists of large, bizarre, often spindle-shaped, neoplastic cells resembling a soft tissue sarcoma. We report here such a case of ALCL with both pulmonary and multiple nodal involvement in a 47-year-old woman who initially presented with fever, cough, sputum, itching skin, and weight loss. The initial transbronchial lung biopsy showed discohesive pleomorphic malignant cells in a strong inflammatory milieu reminiscent of inflammatory malignant fibrous histiocytoma (MFH). Subsequent cervical lymph node biopsy revealed a spindle cell sarcoma predominantly composed of plump spindle and oval neoplastic cells in interweaving fascicles, with sparse inflammatory infiltrates, resembling pleomorphic-storiform type of MFH. However, these tumor cells in the lung and node lesions revealed essentially similar immunohistochemical features that were positive for CD30, EMA, TIA-1, granzyme B, and fascin, but negative for anaplastic lymphoma kinase (ALK), and T- or B-lineage-specific marker. The spindled cells stains diffuse strong positive for smooth muscle actin (SMA), along with vimentin. Further studies showed that the tumor produced large quantities of the proinflammatory cytokines interleukin-2 (IL-2), IL-6, and IL-8, which we believe may contribute to the pathogenesis of sarcomatoid transformation of this tumor, and was associated with the patient's inflammatory symptoms. To the best of our knowledge, this is the first reported case of sarcomatoid variant of ALK-negative ALCL with null cell phenotype and in situ production of proinflammatory cytokines presenting as multiple nodes and pulmonary involvement.
