RESUMEN
INTRODUCTION: Inflammatory myofibroblastic tumors are a rare cause of primary lung tumors, most often solitary and in more than 50% of cases detected in individuals under 40 years of age. OBSERVATION: A 17-year-old patient consulted in pneumology for development of hemoptysis over a period of two weeks. Thoracic computed tomography revealed a left lower lobe cavity 24mm in diameter with bronchial fistulation and hydro-aeric level. Bronchial fibroscopy by mini-endoscope highlighted an endobronchial lesion in a subdivision of the sub-segmental posterior aspect of the left lower lobe. Paraclinical assessment highlighted a probable inflammatory myofibroblastic tumour. A surgical intervention was indicated and a lower left lobectomy performed. Histological analysis confirmed the presence of the tumour, which was resected in healthy margins by left lower lobectomy.

Pulmonary nodules are a common reason for consultation and their investigation must always exclude a possible neoplastic cause. This means that, in addition to a thorough history, investigations may be necessary which are sometimes invasive and therefore potentially a cause of iatrogenic harm. The toxic aetiologies for pulmonary nodules are rare. We report a case of a patient with pulmonary nodules occurring predominantly in the right lung, about 1cm in diameter, non-cavitating without calcification, and sometimes surrounded by a peripheral halo. The nodules were a chance finding during preoperative evaluation. After a comprehensive review, a reaction to an inhaled irritant was the preferred hypothesis, specifically overuse of a compound insecticide containing, in addition to the propellant gas and solvent type hydrocarbon - a mixture of piperonyl butoxide, of esbiothrine and permethrin. Removal of this led to the complete disappearance of nodules. Pathological examination identified bronchiolitis obliterans with organising pneumonia accompanied by non-necrotizing granulomas and lipid vacuoles.

INTRODUCTION: FOLFOX 4 chemotherapy (5-fluorouracil, leucovorin and oxaliplatin) is the standard adjuvant treatment for stage III colon cancer. The principal secondary effects described are haematological, gastro-intestinal or neurological. A single case of obliterative bronchiolitis with organising pneumonia has been described recently. CASE REPORT: We report the case of a female patient aged 74 years who, after 12 courses of FOLFOX 4 chemotherapy, developed acute onset of severe shortness of breath and a dry cough but remained afebrile. A thoracic CT-scan showed symmetrical bilateral interstitial infiltration that was reticular in appearance, and predominantly basal and peripheral in distribution. Broncho-alveolar lavage revealed an alveolitis with 9% eosinophils and 4% neutrophils. Transbronchial biopsies showed the appearances of obliterative bronchiolitis with organising pneumonia. Systemic corticosteroid treatment led to a remarkable clinical and functional improvement. CONCLUSION: To our knowledge, this is the second case of obliterative bronchiolitis with organising pneumonia that has been described following adjuvant treatment based on FOLFOX 4.

Mass lesions of the mesentery may be fortuitously encountered on computerized tomographic (CT) scans, posing a diagnostic challenge. Despite CT, magnetic resonance (MR) imaging and a surgical biopsy, a patient with mesenteric lipodystrophy was misdiagnosed as having a low-grade mesenteric liposarcoma. Spontaneous regression of the mass on control CT scan and review of the pathological material prompted us to reconsider the diagnosis of malignancy. Because a wide variety of tumors and pseudotumors produce alterations in the density and volume of mesenteric fat on CT scan, a surgical biopsy is usually necessary to obtain a tissue-specific diagnosis, but even then pathological findings may be equivocal. As final resort the natural evolution assessed by radiological follow-up can be of help in determining the nature of the disease.
