AB 47. Incidental non-hodgkin lymphoma in a patient with squamous cell carcinoma of the lung: a case report

Background The appearance of multiple malignancies in the same patient is a relatively rare occurrence, which can either be synchronous or metachronous. The etiology is multifactorial and some of the factors involved in the pathogenesis of these conditions include genetic predisposition, immunodefiency, radiation therapy, chemotherapy and various infectious agents. We report the case of a patient with squamous cell lung cancer in whom non-Hodgkin lymphoma was accidentally found in paratracheal lymph nodes.

AB 34. Solitary fibrous tumor with focal malignant transformation. Description of a rare case

Background Solitary fibrous tumor SFT is a rare mesenchymatogenic neoplasm, with intermediate malignant potential, usually localized in pleura. Malignant transformation observed at 23% of intrathoracic SFT. We present the unusual case of a 62-year-old patient presented to our hospital with a large SFT of the lung.
