[Inflammatory pseudotumor of the lung. An anatomoclinical study of a case report]. / Pseudotumeur inflammatoire du poumon. Etude anatomoclinique d'une observation.

One solitary pulmonary nodule was observed in a 47-year-old woman with history of right thigh liposarcoma 1 year before. Histological examination of the pulmonary specimen excluded liposarcoma metastasis and revealed an inflammatory pseudotumor. These unusual lesions with an excellent prognosis may exhibit, as in our case, atypical radiologic features and nuclear atypia, making the diagnosis difficult with malignancy.
