INTRODUCTION: The incidence of @entity4593 in Europe is estimated at one case per 100,000 @entity1 /year. Despite the low incidence of @entity3069 infection, it can result in a nodular lesion simulating @entity2 . We report a case of @entity4593 , mimicking @entity2 , which led to a lobectomy. CASE REPORT: It was a right pulmonary upper lobe nodule found in a 63-year-old @entity1030 @entity1 , partially nephrectomized for @entity703 , and weekly treated by @entity1499 for @entity309 . FDG uptake was weakly positive on PET-CT (SUV=2.2) in the upper fissure. Bronchoscopy yielded no lesions and no bacteriological findings. Percutaneous transthoracic lung biopsy revealed @entity2220 stage T1 (a) N0M0. An upper lobectomy with lymphadenectomy was performed. Histological examination revealed @entity738 surrounded by giant cells suggestive of @entity6551 . The bronchial washing fluid culture was positive for @entity3069 after 7 weeks. CONCLUSION: In pseudo-neoplastic forms of @entity4593 , the presence of alveolar, inflammatory cytonuclear abnormalities can mimic an @entity420 . Making the difference between the cytonuclears defects related to @entity32 remains a daily challenge in histopathology.
