Malignant Fibrous Histiocytoma of the Lung

Malignant fibrous histiocytoma (MFH) is a primitive sarcoma originating in the deep soft tissue and composed of fibrocytic and histiocytic cells in a storiform pattern. It is rare but the most common soft tissue sarcoma of adulthood. MFH occurred in various epithelial organs derived from the supportive mesenchymal elements. The lung represents an extremely rare primary site. We have experienced one case of MFH, arising in the lung parenchyme in 67 years old male patient with cough for 6 months. The patient was taken right upper lobe and right middle lobe lobectomy with good post-operative results. But another MFH was recurred in the left upper lobe 3 months after complete resection. So he had been treated with chemotherapy and radiofrequency ablation of tumor. Then he continued to be treated with chemotherapy

A Case of Bronchiolitis Obliterans Organizing Pneumonia Following CHOP Chemotherapy and Filgrastim Use in a Patient with Diffuse Large B-cell Lymphoma / 결핵및호흡기질환

Bronchiolitis obliterans organizing pneumonia (BOOP) is often diagnosed in patients with pneumonia who respond poorly to antibiotics. BOOP is often idiopathic, and the etiology of the remaining cases has been attributed to a wide range of agents or medical conditions. When a patient develops the clinical symptoms characteristic of BOOP, the medical team must endeavor to determine the etiology of this disease because it can be treated with glucocorticoid and avoidance of the causative agent. In particular, if BOOP is diagnosed during or after chemotherapy for a malignancy, the possible culprit agent can be the anti cancer drugs but other drugs used for supportive care must be also be considered. We report a case of BOOP that arose after CHOP chemotherapy and a filgrastim injection in a patient with a diffuse large B-cell lymphoma.
