Large Cell Lung Carcinoma with Unusual Imaging Feature, Immunophenotype and Genetic Finding

We present a case of large cell lung carcinoma in sixty-one year old male with typical lung cancer symptoms but unusual radiological presentation and immunophenotype. Tumor morphological finding related to its radiological finding was suggestive for large cell lymphoma or carcinoma, but its immunophenotype made confusion for pathological diagnosis. No p53 mutations were detected in genetic investigation. Multidisciplinar diagnostic approach to some tumors is useful for their final diagnosis.
